Ladies & Gentlemen, dear friends from Taiwan
I am very delighted to have the pleasure of your company here in Munich.
The Zoological Society Wallacea was founded one and a half years ago, during an entomologist=s meeting in Kranichfeld, Thuringia. The main focus of the society is to support the contact between zoologists working on topics related to the Indo-Australian region, and we see this region in its widest range from South East Asia to New Guinea, of course including Taiwan, and eastwards to the Solomon Islands and maybe Fiji, Tonga and even Samoa.
Our good connections to Taiwan were established 6 years ago, when Prof. Schönitzer met Keh-miin Chen from the press office of the Taiwan Representation Office in Munich. Mr. Chen is an enthusiastic entomologist and was the main organisator of the Taiwan exhibition during the Bavarian Entomological Day in March >96. Already in September >96 the first symposium on ANature conservation in Taiwan@ was held in the Zoological State Collections here in Munich.
So, the special topic AZoogeographic aspects of Taiwan@ is the natural result of our continuous contacts and increasing friendship with the representatives of the Taipeh Representation Office in Munich, who again made a fantastic exhibition possible, here in the lobby of the ZSM, which I would highly recommend you to look at today.
Last but not least, I have to express my thanks to our friends from Taipeh Representation Office, Munich, for their kind help and generous financial support for this event - General Director Jiunn-man Liu, Director Tsing-min Chao, Mr. Liang and all the others, thank you very much!
Of course I have to thank the staff of the ZSM who helped in the well-established manner.
Ulf Buchsbaum pushed this congress from the beginning and did the main organisation, thank you Ulf. Marianne Müller was a great help in arranging the logo of the society and the poster of the congress program.
My special thanks go to the director of the ZSM, Prof. Haszprunar, for the hospitality to carry out this congress in the rooms of the ZSM - Prof. Haszprunar, thank you very much.
Ladies & Gentlemen, I wish you a successful congress, informative discussions and many possibilities of closer acquaintance.

The status of Insect biodiversity and biogeography studies in Taiwan
Prof. Dr. Jeng-Tze Yang
Department of Entomology, Chung Hsing University, Taichung 402,Taiwan

Abstract
The number of Taiwanese insect taxonomists including graduate students is 65 in the year 2000. It shows a 30% increasing than the number 50 of 1997. There are 17,634 described species of insect are recorded as distribution in Taiwan. It is about 2.2% of the total species number of the world (787,393 species). The proportion of insect taxonomists by the species looks higher than that of other animal taxonomists in Taiwan. However most insect taxonomists focus only on their own interested groups, leaving many other groups untouched. If we look at the order category, there are only 14 insect orders have been studied by Taiwanese taxonomists. The top four popular insect orders in Taiwan are Homoptera (24%), Diptera (13%), Coleoptera (11%) and Hymenoptera (11%). There are more and more taxonomists working on Orthoptera and Lepidoptera during the past 5 years. Although many more young taxonomists joined the taxonomic team, but no sign of increasing in studying groups. The challenge to taxonomists was focused on identification of the agricultural insect pests and the natural enemies. It is now shifting to focus on the insect biodiversity, conservation and some environmental issues. The requirement of taxonomic man-power is increasing fast and suddenly. It is necessary to build up a identification service network in Taiwan in order to resolve the shortage of taxonomic man-power and to proof the quality of the services. A insect identification service network has been proposed by the author. It is the idea to connect and unite the insect taxonomist from all over the world to do the insect identification for the applied researchers. Besides, there are some topics that the insect taxonomists are undergoing study in Taiwan such as Taiwan Biodiversity Network (TaiBNET), Long Term Ecological Research (LTER), Taiwan Digital Archieves projects and Quarantine insects identification. There is an insect taxonomy and biodiversity research team is going to be started to do supporting research for the national biodiversity program in order to meet the requirement of Convention on Biological Diversity. There is no much taxonomist study on the insect biogeography in Taiwan until 5 years ago. The subject concerned about the intermediate and/ or overlapping effects of the insect fauna in Taiwan is the main theme for the tasks of geographic study by now.

Malesian Island Biogeography: From Alfred Russel WALLACE to Robert H.MACARTHUR and beyond. What makes WALLACEA so unique?
Prof. Dr. Josef H. Reichholf
Zoologische Staatssammlung Muenchen, Muenchhausenstr. 21, D-81247 Munich.

A. R. Wallace, puzzled by the extraordinary richness of the Malayan archipelago, tried to delineate the oriental fauna (and flora) in what is now Indonesia against the Australian. The result was the subsequently several times modified "Wallace's Line".Though indicating the intergradation of two different major faunas, "the line" did not solve at all the question why this region is so rich in species. Roughly a hundred years later, Robert MacArthur, together with Edward O. Wilson, developed the "Theory of island biogeography" as a mathematical concept. It includes two main processes, the rate of immigration of species onto an island, and the rate of extinction; both processes balancing over time to a dynamic equilibrium of species richness. Two factors are of major importance in this proces, the one being the size of the island, the other the distance from a mainland (as a source of species). The famous and widely applied formula gives the process on the power equation: S = C Az.
S is the (final) number of species, A the area (size) of the island, C the species group specific factor (giving the average number of species of the taxon considered per unit of area; conveniently per square kilometre) and the exponent z represents the increase of species with area in a double logarithmic scale (i.e. the continental-insular distributional exponent). MacArthur's species-area-relationship proved to be very useful in the now emerging field of quantitative and predictive biogeography, especially with respect to species losses due to habitat fragmentation and with respect to questions of how big natur reserves should be to enable the survival of most of the species present, finding critical size dimensions and so on. But applied to the richness of what we now call WALLACEA the species-area-relationship only partly can explain the extraordinary richness, which in fact equals at least that of Amazonia but very likely surpasses it (as it is shown on the charts in the lecture). Going back to A.R.Wallace, the modern look onto the problem of how two major faunas intermingle where they meet in South-east Asia, the recent findings in geology and earth history, especially plate tectonics, provide a better tool for understanding the richness of Wallacea. Because is has not only been the collision of two continental plates, but also the extensive changes of sea levels during the Pleistocene, which gave rise to a series of unification and isolation events. These should have acted as a species pump in just the same way as it has been the case in Amazonia, but in right the inverse way: During the glaciations sea levels fell to less than 100 metres or so below the present level, which united much of the South-east Asian islands to the mainlands, but in Amazonia the massive reduction in rain fall isolated the tropical forest into an archipelago of island-like forest remnants. In the subsequent interglacials, the rainy & warm periods, sea levels rised again and brought the Malesian region backt into the state of the most extensive area of islands of all sizes whereas Amazonia became a huge closed forest 2.5 times the size of present day Indonesia. This mechanism of a quite dynamical earth during the last few million years created in fact a much higher species density than predictable according to mere immigration & extinction processes according to the MacArthur-formula.
Nevertheless some other puzzling facts remain, and they do not fit neither into the geological process of island formation nor into MacArthurs model. There are several instances of taxa which have their neares relatives in Central and South America (e.g.the poisonous pit vipers, the China Alligator, several palm genera and so on). The author's interpretation of these puzzling biogeograpic facts is based on the conditions of the trans-pacific ocean currents during the Tertiary, when North and South America had not been united by the Central American land bridge. This state lasted for about 50 Million years and should have made the equatorial current much stronger than after the closing of the opening between South and North America. Many taxa may have come across the Pacific driven by the very strong and fast flowing current - and became established as parts of flora and fauna not only in South-east Asia but as far reaching as Madagaskar and other marginal parts of the Indian ocean. It is this third component which fills the gaps in explaining the high diversity of Wallacea, which in fact is the most diverse region in the world. Otherwise recent developments in human land use forms, expecially the cutting of tropical forests in which Indonesia is second only to Brazil, highly endanger the biotic richness oth this region. Indonesia is top ranking in the number of endangered species worldwide. But it is the example of Taiwan, which gives hope and which can be used as a model for the integration of modern development and conservation of natural resources and diversity. Despite being very densly populated (23 million people on a mere 36 000 square kilometres of size), the degree of endandered species is very low. A special look onto Taiwan, therefore, can reveal the options for preserving Wallacea's extraordinary wealth in natural diversity.

Pacific monitor lizards of the Indo-Australian Archipelago - A most successful invasion
K. M. Philipp
Zoologische Staatssammlung Muenchen, Sektion Herpetologie, Muenchhausenstr. 21, 81247 Munich.

Abstract
The pacific monitor lizards (Varanus indicus group) are a group of closely related big-growing monitor lizards. The species group ranges from Sulawesi in the west to the Solomon Islands in the east and from Australia in the south to Micronesia in the north. Until now nine species are recognized: V. caerulivirens, V. cerambonensis, V. doreanus, V. finschi, V. indicus, V. jobiensis, V. melinus, V. spinulosus and V. yuwonoi. Many of the listed species have been discovered and described just recently. It seems that many of them have very limited distribution areas. Therefore the knowledge on their ecology is still very limited. A tenth species from the Solomon Islands will be published soon (Böhme et al. in press).
All ten species are introduced with special regards on their diagnostic characters and distribution pattern.
Field observations on the niche segregation of the three New Guinean species V. doreanus, V. indicus and V. jobiensis are presented. V. indicus is the least specialized and shows a high ecological plasticity. As an euryoecious reptile species it inhabits numerous different vegetation types (e.g. beach woodland, littoral forest, mangrove forest, mixed alluvium forest and mixed hill forest). Most frequently V. indicus is found in vegetation types that are influenced by saltwater. Contrary V. doreanus and V. jobiensis seems to avoid all saltwater influenced forest types. These species prefer mixed alluvium forest and mixed hill forest. Stomach content analyses of museum vouchers reflect such a special niche segregation of the New Guinean species. Furthermore these stomach content analyses give some first impression of the life habits of the remaining species of the Pacific monitor lizard group, as no field observations are published and their ecological requirements are almost unknown.

The Zoogeography of Taiwan’s Notodontidae
Alexander Schintlmeister
Calberlastr. 3, D-01326 Dresden, e-mail:schintlm@aol.com

Abstract
The Exploration of Taiwan’s Notodontidae started practically 1910, when Wileman published his first article dealing with Taiwanese Heterocera, including a dozen Notodontidae. Later more the Notodontidae from Taiwan become better known, mainly recorded by British (Wileman, South), German (Strand) and Japanese (Kishida, Matsumura, Nakamura, Okano, Sugi) authors. Recently Schintlmeister (1992; Schintlmeister & Fang, 2001) dealt with China Notodontidae. Actually also Taiwanese scientists (Chang, Lin and Shen) made important contributions on Taiwan’s Notodontidae.
From 1995 until today, particularly by Hungarians Expeditions (T. Csõvári, Csorba, Gy. Fàbián, Herczig, M. Hreblay (‡), Juhasz, S.T. Kovács, A. Kun, Gy. M. László, L. Mikus, L. Nèmeth, L. Peregovits, & G. Ronkay, L. Ronkay, S. Simonyi,
I. Soós, P. Stéger, C. Szabóky and others) the knowledge of Taiwanese Heterocera increased rapidly. The collections covered the whole islands and were running also in wintertime. About 11.000 specimens of Notodontidae come to Europe (today mainly housing in the Museum Witt, Munich) and were studied by me.
The last available Checklist of the Notodontidae of Sugi (in Heppner & Inoue 1992) lists 114 species. I know actually (2002) 131 species from Taiwan (under them also a few species new to science). I expect, that we know today more then 90% of the Taiwan Notodontids and this is the database for the following lecture.
For the zoogeographic analysis I use the category "Faunenlement", introduced by de Lattin (1957, 1967). Each species started its expansion (sometime wider, sometime restricted on a small area) from center of origin respectively a refugee. According this refugee the Faunal Element are named. In Schintlmeister 1989, the method is discussed and the Palaearctic Notodontidae are assigned to Faunal Elements.
The base of such an analysis must be the exact knowledge of the whole area of the studied species. In the lecture some examples are given, how an insufficient knowledge of the area would lead to wrong conclusions. It is to notice, that a species known exclusively from Taiwan must not be in every case an endemic species. In many cases such species was discovered later outside of Taiwan, e.g. Syntypistis nigribasalis (Wileman, 1910), Phalera obscura Wileman, 1910, Micromelalopha baibarana Matsumura, 1929. Also the taxonomy of the species must be clear. Particularly in Taiwanese Notodontids in former times many rare species was recorded as "endemics" because of the impossibility of comparison. Since more material arrived in Europe it was possible to compare material from Taiwan with related taxa. So the number of Endemics decreased in the time, e.g. Acmeshachia takamukui Matsumura, 1929 (described from Taiwan) = gigantea Elwes, 1890 (described from Darjeeling), Megashachia takamukuana Matsumura, 1929 (Taiwan) = fulgurifera Walker, 1858 (Assam), Subwilemanus pictus Kiriakoff, 1963 (Zhejiang) = Fentonia parabolica Matsumura, 1925 (Taiwan).
According this method the Taiwan Notodontidae belonging zoogeographic to the following categories:

    1. Pacific Elements 24% + 29% Taiwan Endemics
    2. Mandshuric Elements 9%
    3. Himalayan Elements 7%
    4. Siamic Elements 7%
    5. Oriental Elements 24%

Often the centres are split into subcenters. The Pacific centre contains the Sinopacific subcenter (refugee is situated in SE mainland China) and the Taiwanese subcenter. All (really) endemic species of Taiwan should belong to the Pacific-Taiwanese Faunal elements. Remarkable is the very high number of endemic Biretinae (bamboo feeding prominent moths). Characteristic examples of Taiwanese endemics are Torigea formosana Nakamura, 1973, Paracerura subrosea (Matsumura, 1927) and Notodonta griseotincta Wileman, 1910. Sinopacific Faunal Elements are Tarsolepis taiwana Wileman, 1910, Periergos magna (Matsumura, 1920) and Betashachia angustipennis angustipennis Matsumura, 1925. The Pacific Faunal Elements extends in some cases their area until Yunnan, but mostly they are restricted to SE China.
Besides the Pacific Elements the Oriental Faunal Elements of expansive type are important for the Taiwanese fauna: Neopheosia fasciata, (Moore, 1888), Chadisra bipars (Walker, 1862), Phalera combusta (Walker, 1855). This means mainly expansive Sundanian Faunal elements of many subcenters. However the influence of the geographic nearby situated Philippine subcenter seems to be unimportant, compared with the Sumatran subcenter.
The Mandshurian Elements (the majority of the Taiwan species probably immigrated from Japan) lives in Taiwan often the higher altitudes, e.g. Syntypistis pryeri (Leech, 1889), Uropyia meticulodina (Oberthür, 1884), Lophocosma sarantuja Schintlmeister & Kinoshita, 1984, Hupodonta lignea Matsumura, 1920.
The Siamic Faunal Element, introduced by Schintlmeister (2001), groups species originated in Indochina (particularly N.Vietnam). Only a few species reached Taiwan: Paracerura priapus (Schintlmeister, 1997), Pseudosomera noctuiformis Bender & Steiniger, 1984, Hiradonta angustipennis Nakatomi & Kishida, 1984
The Himalayan Faunal Elements are differing in its area-type from the Siamic Elements (the area includes the Himalaya). They are also a minority in Taiwan, e.g. Megashachia fulgurifera (Walker, 1858) Acmeshachia gigantea (Elwes, 1890), Somera viridifusca Walker, 1855 (which is Polytypic), Cleapa latifascia Walker, 1855.
Besides the zoogeographic analysis there seems to be in some cases in Taiwan a concentration of many nearly related species.
The Genus Paracerura Schintlmeister 2002 contains in the oriental region 13 nearly related species in 3 groups. Everywhere From India to Australia only 2 species are occurring sympatric. In Taiwan there are 3 species of all groups sympatrically.
In the genus large genus Besaia Walker, 1865 in Taiwan there is a group of 4 similar and endemic species (sordida Wileman, 1914, inconspicua Wileman, 1914, nebulosa Wileman, 1914 and a hitherto undescribed species), which have outside of Taiwan no near relatives.
These two examples give us a view on the island of Taiwan as a refugee and "hot spot" of evolution.

Phylogenetic relationships and biogeography of Aglaopini Alberti, 1954 (Lepidoptera, Zygaenoidea, Zygaenidae sensu lato)
Shen-Horn Yen
Department of Biological Science, Imperial College at Silwood Park, Ascot, Berkshire, SL5 7PY, UK
Department of Entomology, The Natural History Museum, Cromwell Road, London, SW7 5BD, UK

mail: shenhornyen@hotmail.com ; s.yen@ic.ac.uk

Abstract.
The chalcosiine tribe Aglaopini Alberti, 1954 was previously based only on Aglaope Latreille, 1809, a genus containing two similar species confined to S.W. Europe and N. Africa. Although Aglaope bears several apomorphies, which was thought to be a distinct lineage from all the other genera, however, the phylogenetic relationships and validity of this tribe have become very questionable since Formozygaena Inoue, 1987 from Taiwan was included. According to my present cladistic analysis of the generic level phylogeny for the whole of the Chalcosiinae sensu lato, a hypothetical relationship of (Atelesia+(Aglaope+(Philopator+Formozygaena))) is reconstructed, and this clade may represent a terminal rather than a basal one. Since Atelesia is endemic to New Guinea, Philopator and the Agalope genus complex range throughout the Himalayas, S.W. China and Indochina Peninsula, the proposal of an earlier vicariance of Aglaope from all the other genera is rejected. The phylogeny favors a new hypothesis that Aglaope have been dispersed from the Himalayas to the W. Palaearctic region with a speculated extinction between these two areas. Finally, Aglaopini (viz. Aglaope and Formozygaena) is not accepted as a valid tribe because it may cause Agalopini paraphyletic. The apomorphies of Aglaope are suspected to reflect its isolated distribution and completely different habitat from all of its other Asian relatives.

Lepidoptera diversity at low and high altitudes in Taiwan and Luzon
W. Mey & W. Speidel
Museum für Naturkunde, Humboldt Universität Berlin, Invalidenstr. 43, D - 10115 Berlin, Germany

Abstract
Two localities were selected in central Taiwan, the first one (Huei-sun) is situated in about 500 m above sea-level, the second (Mei-feng) in about 2000 m. The collecting sites in northern Luzon are situated in the Central Cordillera, Benguet Province at adequate altitudes. The Lepidoptera were collected by light. We have studied all taxa (Microlepidoptera, Pyraloidea, Heterocera) except Rhopalocera. The collected specimens were counted and identified to family. The morphospecies concept was used to determine the species numbers. The two localities of both islands are compared at the species and family level. We found a considerable congruence between the fauna of Taiwan and that of mainland China especially in the families Noctuidae and Crambidae, Acentropinae in both altitudes. However, it is problematic in many families to separate Palearctic and Oriental elements in Taiwan, though it can be easily seen that the fauna of the high mountains of Taiwan has a distinctive Palearctic aspect. The composition of the Lepidoptera communities in the Philippines is rather distinct from the localities in Taiwan. The number of species common to both islands is extremely low and doesn not exceed 0,5 %. The altitudinal differences are less pronounced and the diversity at the family level is lower. This will be demonstrated by a quantitative analysis

Entomological reasearch visits to Taiwan
K. Schönitzer & A. Dubitzky

Zoologische Staatssammlung Muenchen, Muenchhausenstrasse 21, D - 81247 Munich

Abstract
We reported on the scientific cooperation between the Zoologische Staatssammlung München, Germany and the entomological department of the National Chung Hsiung University of Taichung, Taiwan. In the course of this cooperation, which was supported by the DAAD and NSF (PPP-Project D/0039914), two groups of German entomologists visited Taiwan to collect insects. In the year 2000 Mr. Wolfgang Schacht, Mr. A. Dubitzky and Mrs. S. Szczepanek made a trip to Taiwan, and in 2001 Dr. K. Schönitzer, Mr. Buchsbaum and Mr. Schacht collected insects there. Some Taiwanese scientists, on the other hand, visited Germany in 2001 and 2002. This cooperation was initiated by the helpful initiative of Mr. Keh-Miin Chen (Government Information Office, Taipei). The scientific head of the Taiwanese partners is Prof. Jeng-Tze Yang from Taichung . The Taiwanese partners enabled us to travel in Taiwan and use the excellent Taiwanese infrastructure to collect in different sites. We want to express our deep gratitude to the friends and colleagues for excellent organisation of our trips and their great hospitality. The partners agree that one third of the material as well as all holotypes are to be deposited in Taiwan after scientific exploration and identification.

In the lecture we introduced to the beautiful nature of Taiwan, especially the magnificent life of insects and showed some aspects of daily life and of the Chinese culture. Of special interest is the high standard of the Universities we visited in Taiwan with their field stations in different sites of ecological value.

Plant Galls in Taiwan
Sue-Yen Yang1 , Jeng-Tze Yang2, and Ming-Yih Chen1
1. Dept. of Botany, National Chung-Hsing University, Taichung, Taiwan 402
2. Dept. of Entomology, National Chung-Hsing University, Taichung, Taiwan 402

Abstract
Based on the inventory during 1994?2000, 255 kinds of insect-induced galls induced on 150 plant species have been recorded in Taiwan. The Cecidomyiidae of Diptera is the dominant gall maker. 97% insect galls were found in angiosperm, in which Lauraceae ranked as the highest one followed by Fagaceae. 57% insect galls were on the leaf and 29% on the stem. Among the 200 forms of insect galls collected in Taiwan, the gall makers of 130 types were recognized. They belong to 5 orders and 10 family groups.
The interaction between the plant genus Ficus and the fig wasps shows the coevolution between plants and insects. The Hymenoptera is a major group of gall inducers and the most parts of gall wasps are highly host specificity in this study.
Key words: Lauraceae Fagaceae, Gall-wasps, Hymenoptera, Taiwan.

Preliminary report on Tetrigidae (Orthoptera: Tetrigoidea) from Taiwan
Ming-Yu Tsai and Jeng-Tze Yang
Department of Entomology, 250 Kuokuang Rd., National Chung Hsing University, Taichung, 40227 Taiwan, R. O. C.

Abstract
Taiwan is located on north of the western Pacific ocean in geography and set in the Oriental region in biogeography. Tetrigoidea includes 2 families, Tetrigidae and Batrachididae. There is no single species of Batrachididae in Taiwan as far as we know. There were 16 genera and 36 species of Tetrigidae were recorded as distribution in Taiwan. They belong to 4 subfamilies, Cladonotinae, Scelimeninae, Metrodorinae, and Tetriginae. In this study totally 249 localities in Taiwan and its adjacent offshore islands were surveyed during 3 years. After this study, there are 18 genera and 38 species, in which 2 genera and 2 undetermined species, Alulatettix sp. and Thoradonta sp. are newly records to Taiwan. In this work, the key to Taiwanese genera in each subfamily was provided. The illustrations of some species representative to the subfamilies were also presented.

Keywords: Orthoptera, Tetrigidae, fauna, key, Taiwan
