Significance of Oriental Taxa in Phylogeny of Crab Spiders (Thomisidae S.Lat © 2016. Indian Journal of Arachnology 5 (1-2): 143-171 ISSN 2278-1587 (Online) SIGNIFICANCE OF ORIENTAL TAXA IN PHYLOGENY OF CRAB SPIDERS (THOMISIDAE S.LAT. AND STIPHROPODIDAE) Pekka T. Lehtinen Zoological Museum, FIN-20014 University of Turku, Finland [email protected] ABSTRACT Numerous taxonomic changes in Oriental crab spiders are listed with justifications and suprageneric taxa are discussed at global level. Similar pattern of more than one inner cheliceral setae is found to be a synapomorphy for Borboropactidae, Stephanopidae and Thomisidae. The separation of Stiphropodidae as a valid family is confirmed. The polyphyly of Dietinae sensu Petrunkevitch, 1928 is confirmed and its tribes are listed in Thomisidae, Thomisinae (Dietini, Alcimochthini, and Amyciaeini) and Bomidae (Apyretini, Tagulini, Emplesiogonini, Mystariini, Porropini, and Talaini). Boliscini, new tribe of Bomidae is created for Boliscus Thorell, 1891 and Corynethrix L. Koch, 1876, and family group names based on Bomis L. Koch, 1874 without known female is discussed. A strange gnathocoxal process in all Boliscus spp. is described. The Stephanopine groups Phartini, Borboropactini and new tribes Cebrenninini, Angaeini and Geraestini are transferred to Borboropactidae Wunderlich, 2004, and Phrynarachnini, Stephanopoidini, and Hedanini to Thomisidae s.str. These transfers are based on similar structure of copulatory organs of both sexes, trichobothrial patterns of legs and several ultrastructural characters. Phrynarachne Thorell, 1869 with type species P. rugosus Latreille, 1804 is now included in the same tribe as Synema Simon, 1864. Senoculifer Balogh, 1936 from New Guinea is transferred from Philodromidae to Thomisidae and synonymized with Demogenes Simon, 1895. Xysticus palawanicus Barrion, 1995 is synonymized with Alcimochthes limbatus Simon, 1885 (Alcimochthini). Lehtinelagia Szymkowiak, 2014 and its type species Xysticus evanidus L. Koch, 1867 (Queensland) are synonymized with Tharrhalea L. Koch, 1875 and its type species T. albipes L. Koch, 1875 (Queensland). Ocyllus Thorell, 1887 with juvenile type species O. binotatus Thorell, 1887 from Myanmar is synonymized with Cebrenninus Simon, 1887; the latter is selected as valid for simultaneously published names. Ocyllus pallens Thorell, 1895 is transferred to Oxytate L. Koch, 1878 in Dietini. Taypaliito Barrion, 1995 and its type species T. iorebotco (Philippines, Palawan) are synonymized with Talaus (Microcyllus) Thorell, 1892 and its type species T. (M.) elegans (Indonesia, Sumatra). Takachihoa Ono, 1985 (type species Oxyptila truciformis Bösenberg & Strand, 1906 = Xysticus nebulo Simon, 1909, syn. n.) is synonymized with Pycnaxis Simon, 1895, and Coriarachne nigrostriata Simon, 1886 is transferred to Pycnaxis. Tharrhalea maculata Kulczyński, 1911 and T. variegata Kulczyński, 1911, both from New Guinea are transferred to Massuria Thorell, 1887. INTRODUCTION This work is a part of worldwide revisional study of Thomisidae sensu auct. It is not formally a complete modern revision, as it is based on selected important results. It is a list of results with carefully justified taxonomic changes in the Oriental taxa of this group. In this way, a lot of taxonomic results about this group can be published rather quickly. Limitation of space and time available makes the inclusion of normal complete data of true revisions impossible. December, 2016 143 Significance of oriental taxa in phylogeny of crab spiders Pekka T. Lehtinen Complete descriptions of treated taxa are not presented here, but taxa with new status or limitation are shortly diagnosed and reasons for the new opinion is explained. Exceptionally extensive personal field work in all tropical areas has also made possible the conclusions here, even though some of them much deviate from previously presented results. Problems to be solved. a) Many name-bearing types of crab spiders described long ago by Simon, Thorell, L. Koch, Karsch, Workman, O. Pickard-Cambridge, and other spider taxonomists of the past have never before been studied after their original description, even those preserved in well known European museums in Paris, Genoa, Stockholm, London, Geneva, Oxford, and Dublin. b) Several local specialists in the Oriental region have not at all or quite seldom, at least, tried to co-operate with colleagues or at least ask for advice from well trained specialists from Europe, North America or Australia. This is unfortunately true for most arachnologists from India, Pakistan and Philippines working with crab spiders after 1960. Positive exceptions have been several current arachnologists in Japan, China, Taiwan, Sri Lanka and Thailand, while much arachnological work for Laos (in addition to the work in Thailand) has been recently carried out by some active European specialists. Incorrectly placed Philippine crab spiders have been checked in IRRI, Los Baños, and many of Dahl´s (1907) errors from slides in ZMB. c) Fruitful work of most European, North American and even of many local arachnologists has been prevented and/or complicated by worldwide unique policies of some museums, especially ZSI (Kolkata), preventing not only the loan of material, but also suggested work with them on site. d) After the United Nations Conference on Environment and Development in Rio de Janeiro in 1992, governmental offices in many (less developed) countries interpreted the decisions in a way, which largely stopped the real co-operation with scientists in developed countries (except for those living in countries with high economical resources), e.g., by legally prohibiting all transport of biota to foreign countries for scientific purposes. Although the policies were most radically changed in Brazil, almost similar is the situation in Philippines. This explains that the situation does not depend at all on the attitudes of local arachnologists. The results are presented in two parts. Complete description of a new Malagasy-Mauritian tribe of Stephanopidae, new limitation of Stiphropodidae and Bomidae, all changes within the traditional subfamily Thomisinae and within most true members of the tribe Hedanini will be published separately. Bond et al. (2014) and Fernandez et al. (2014) have recently used an entirely different method of molecular biology, phylogenomics, and independently obtained surprisingly similar results as the phylogenetic conclusions presented here that are based on ultrastructural analysis of cuticle, setae and sensory organs. This seems to confirm the applicability of ultrastructure as a reliable method in solving problems of phylogenetic relationships of supraspecific taxa. The aim of this study is to list and discuss taxonomical changes to crab spider taxa of the Oriental region, according to the results of personal work and give sufficient justification for them, though formal details for complete taxonomic revisions are presented only for a few selected cases. Special attention has been directed to the correction of numerous strange taxonomic interpretations of Oriental crab spiders after 1960, both by Indian and Philippine active arachnologists also working with the crab spiders. Essential abbreviations used: * I have checked the holotype/syntypes. This refers to type material of the type species. Indian Journal of Arachnology 5 (1-2) 144 Significance of oriental taxa in phylogeny of crab spiders Pekka T. Lehtinen # I have checked authoritatively identified material. ¤ I have compared topotypical adults of both sexes and juvenile specimens of different age with holotype in cases, where the holotype is not adult. This is the only way to confirm the identity of the holotype in a few cases. Abbreviations for eye and spinneret patterns according to widely accepted formulae. If not otherwise noted, the source of photographed and micrographed specimens is the personal temporary collection (PTL) or ZMT for material collected before 1999. A further technical solution: for all new taxa in Barrion & Litsinger (1995), Barrion is here cited as the only author, as it has been officially confirmed that Mr. Litsinger has not participated to the taxonomic work with results published in this book. This principle should be generally applied as strictly Code-compliant (ICZN, 1999 § 50.1). References concerning the book as such should not be changed. MATERIAL AND METHODS My field research on tropical spiders began in the Oriental region in 1969 by a field trip to Sri Lanka (with four later expeditions). Number of visits to other Oriental areas are listed in brackets: Malaysia (5), Thailand (4), Indonesia: Sumatra, Java, Kalimantan, Sulawesi, Bali, Lombok & Flores (5), Vietnam (1), Philippines: Luzon, Mindoro, Cebu, Palawan & Mindanao (3), India (3), Pakistan (1), Singapore (3), China+Hongkong & Lantau Island+Macau & Coloane Island (3), and Taiwan (5). During these trips, spider material was also collected from Samoa (Savaii, Uapou & Tutuila), Tonga (Tongatapu, Eua, Vavau), Fiji (Viti Levu) (3), Micronesia (Guam), New Guinea with Goodenough Islands & Manus Island (2), Australia with Tasmania (4), New Caledonia (3), New Zealand (2), 19 islands of Polynesia (Cook-, Society-, Marquesas- & Tuamotu- Islands with 5 expeditions), as well from Easter Island, Baltra & Santa Cruz I. of the Galapagos Islands, and Kauai, Oahu, Maui & Hawaii in Hawaiian Islands. In addition to the personally collected material, an absolute provision for this study has been the checking of type material in numerous museums all over the world.

Oster, Jr. A THESIS SUBMITTED IN PARTIAL FULFILLMENT OF THE REQUIREMENTS FOR THE DEGREE OF MASTER OF ARTS Thesis Director's Signature: Houston, Texas May 1971 ABSTRACT JULIUS FIRMICUS MATERNUS: DE ERRORE PROFANARUM RELIGIONUM. INTRODUCTION, TRANSLATION AND COMMENTARY BY Richard E. Oster, Jr. B.A. Texas Technological College M.A. Rice University Julius Firmicus Maternus, author of De Errore Profanarum Religiomm. and Mathesis, is an important but oftentimes over¬ looked writer from the middle of the fourth century. He is known to us only from the two works which he left behind, the former being a Christian polemic against pagan religion and the latter, a work he wrote while still a pagan, being on the subject of astrology. It is his Christian work which is the topic of this thesis. The middle of the fourth century when Firmicus wrote his work, A.D. 346-350, was a time of religious change and struggle in the Roman Empire. Within Christianity there were still troubles over the issues which precipitated the Council of Nicea. Outside of the church, paganism, though on the defensive, was still strong. Legislation had been passed against the pagan cults but it was not being enforced. So, about A.D. 348, a Roman Senator, Julius Firmicus Maternus, wrote a letter Concerning the Error of Profane 1 2 Religions to the Emperors Constans and Constantius. The first section of this work, chapters 1-17, presents the various gods of antiquity. Firmicus ridicules these by de¬ picting the crimes and immorality of the gods, by showing that the pagan gods were nothing more than personified elements or processes of nature.

Mahavidyalaya, Kavathe Mahankal, Sangli. *Former Professor and Head, Department of Zoology, Shivaji University, Kolhapur. ABSTRACT Diversity of spiders from Radhanagari Wildlife Sanctuary, Chandoli Na- tional Park and Koyna Wildlife Sanctuary in Western Ghats is studied for the first time. A total of 247 species belonging to 119 genera and 28 families are recorded from the study area during 2010-2012 with a dominance of Araneid, Salticid and Lycosid spiders. Key words: Spider diversity, Western Ghats INTRODUCTION Spiders comprise one of the largest (5-6th) orders of animals. The spider fauna of India has never been studied in its entirety despite of contributions by many arachnologists since Stoliczka (1869). The pioneering contribution on the taxonomy of Indian spiders is that of European arachnologist Stoliczka (1869). Review of available literature reveals that the earliest contribution by Blackwall (1867); Karsch (1873); Simon (1887); Thorell (1895) and Pocock (1900) were the pioneer workers of Indian spiders. They described many species from India. Tikader (1980, 1982), Tikader, and Malhotra (1980a,b) described spiders from India. Tikader (1980) compiled a book on Thomisid spiders of India, comprising two subfamilies, 25 genera and 115 species. Of these, 23 species were new to science. Descriptions, illustrations and distributions of all species were given. Keys to the subfamilies, genera, and species were provided. Tikader and Biswas (1981) studied 15 families, 47 genera and 99 species from Calcutta and surrounding areas with illustrations and descriptions.

Introduction As one of the most widely recognized group of Arthropods, Spiders are widespread in distribution except for a few niches, such as Arctic and Antarctic. Almost every plant has its spider fauna, as do dead leaves, on the forest floor and on the trees. They may be found at varied locations, such as under bark, beneath stones, below the fallen logs, among foliage, [23] house dwellings, grass, leaves, underground, burrows etc. (Pai IK., 2018) . Their success is reflected by the fact that, on our planet, there are about 48,358 species recorded till now according to World Spider Catalog.
