Davies and Żabka 1989 ILLUSTRATED KEYS TO THE GENERA OF JUMPING SPIDERS (ARANEAE: SALTICIDAE) INAUSTRALIA Var-enrn Topp Devtns eNo Maner ZrsKA Davies, V. Todd and Zabka, M. 1989 I I 13: Illustrated keys to the genera of jumping spiders (Araneae : Salticidae) in Australia. Mem Qd Mus. 27(2): 189-266. Brisbane. ISSN 0079-8835. From the keys, accompanying notes and illustrations 57 presently described genera ofAustralian salticids can be identified, Four genera, Rhombonotus, Canoma, Jotus and Prostheclinahave been reinstated. Three genera, Harmochirus, Omoedus atad Mintonia are newly recorded from northern Australia. The following spiders are illustrated for the first time: ? Canama hinnuleus, 9 Cocolus gibbosus, 6 Coccorchestesferreus, ? Hypoblemum sp., 6 Ligonipes sp., 3 'Lycidas' miehaelseni, 9 Maratus sp., 6 Prostheclina pallida, I Sandalodes bipenicillatus, ? 'Trite' daemelii, and 9 'Trite' longula. Discocnemius Thorell, l88l and Haterius Simon, 1900 are newly synonymised with Zrgonlpes Karsch, 1878, resulting in new combinations: D. lacertosus = L. lacertosus (Thorell, l88l) n. comb.; 1L semitectus = L. semitectus (Simon, 1900) n. comb. The Australian Pystiro spp. have been transferred to Zenodorus thus P. orbiculata = Z. orbiculatus (Keyserling, l88l) n. comb. and P. obscurofemorata = Z. obscurofemoratus (Keyserling, 1881) n. comb.

  • The Short-Range Endemic Invertebrate Fauna of the Ravensthorpe Range
    THE SHORT-RANGE ENDEMIC INVERTEBRATE FAUNA OF THE RAVENSTHORPE RANGE MARK S. HARVEY MEI CHEN LENG Department of Terrestrial Zoology Western Australian Museum June 2008 2 Executive Summary An intensive survey of short-range endemic invertebrates in the Ravensthorpe Range at 79 sites revealed a small but significant fauna of myriapods and arachnids. Four species of short-range endemic invertebrates were found: • The millipede Antichiropus sp. R • The millipede Atelomastix sp. C • The millipede Atelomastix sp. P • The pseudoscorpion Amblyolpium sp. “WA1” Atelomastix sp. C is the only species found to be endemic to the Ravensthorpe Range and was found at 14 sites. Antichiropus sp. R, Atelomastix sp. P and Amblyolpium sp. “WA1” are also found at nearby locations. Sites of high importance include: site 40 with 7 species; sites 7 and 48 each with 5 species; and sites 18 and 44 each with 4 species. WA Museum - Ravensthorpe Range Survey 3 Introduction Australia contains a multitude of terrestrial invertebrate fauna species, with many yet to be discovered and described. Arthropods alone were recently estimated to consist of approximately more than 250,000 species (Yeates et al. 2004). The majority of these belong to the arthropod classes Insecta and Arachnida, and although many have relatively wide distributions across the landscape, some are highly restricted in range with special ecological requirements. These taxa, termed short-range endemics (Harvey 2002b), are taxa categorised as having poor dispersal abilities and/or requiring very specific habitats, usually with naturally small distributional ranges of less than 10,000 km2 and the following ecological and life-history traits: • poor powers of dispersal; • confinement to discontinuous habitats; • usually highly seasonal, only active during cooler, wetter periods; and • low levels of fecundity.

  • Spiders of the Hawaiian Islands: Catalog and Bibliography1
    Pacific Insects 6 (4) : 665-687 December 30, 1964 SPIDERS OF THE HAWAIIAN ISLANDS: CATALOG AND BIBLIOGRAPHY1 By Theodore W. Suman BISHOP MUSEUM, HONOLULU, HAWAII Abstract: This paper contains a systematic list of species, and the literature references, of the spiders occurring in the Hawaiian Islands. The species total 149 of which 17 are record­ ed here for the first time. This paper lists the records and literature of the spiders in the Hawaiian Islands. The islands included are Kure, Midway, Laysan, French Frigate Shoal, Kauai, Oahu, Molokai, Lanai, Maui and Hawaii. The only major work dealing with the spiders in the Hawaiian Is. was published 60 years ago in " Fauna Hawaiiensis " by Simon (1900 & 1904). All of the endemic spiders known today, except Pseudanapis aloha Forster, are described in that work which also in­ cludes a listing of several introduced species. The spider collection available to Simon re­ presented only a small part of the entire Hawaiian fauna. In all probability, the endemic species are only partly known. Since the appearance of Simon's work, there have been many new records and lists of introduced spiders. The known Hawaiian spider fauna now totals 149 species and 4 subspecies belonging to 21 families and 66 genera. Of this total, 82 species (5596) are believed to be endemic and belong to 10 families and 27 genera including 7 endemic genera. The introduced spe­ cies total 65 (44^). Two unidentified species placed in indigenous genera comprise the remaining \%. Seventeen species are recorded here for the first time. In the catalog section of this paper, families, genera and species are listed alphabetical­ ly for convenience.

    Bangladesh J. Zool. 47(2): 185-227, 2019 ISSN: 0304-9027 (print) 2408-8455 (online) CHECKLIST OF THE SPIDER FAUNA OF BANGLADESH (ARANEAE : ARACHNIDA) Vivekanand Biswas* Department of Zoology, Khulna Government Womens’ College, Khulna-9000, Bangladesh Abstract: Spiders are one of the important predatory arthropods that comprise the largest order Araneae of the class Arachnida. In Bangladesh, very few contributions are available on the taxonomic study on these arachnids. The present paper contains an updated checklist of the spider fauna of Bangladesh based on the published records of different workers and the identified collections of the recent studies by the author. It includes a total of 334 species of spiders belong to the infraorders Mygalomorphae and Araneomorphae under 21 families and 100 genera. A brief diagnosis of different families and their domination together with the distribution throughout the country are provided herewith. Key words: Checklist, spiders, Araneae, Arachnida, Bangladesh INTRODUCTION Bangladesh is basically a riverine agricultural country. It lies between 20.35ºN and 26.75ºN latitude and 88.03ºE and 92.75ºE longitude, covering an area of 1,47,570 sq. km (55,126 sq. miles). The country as such offers varied climatic situations viz., temperature, rainfall, humidity, fogmist, dew and Haor- frost, winds etc. (Rashid 1977). With the vast agricultural lands, also there are different kinds of evergreen, deciduous and mangrove forests staying different areas of the country viz., the southern Sunderbans, northern Bhawal and Madhupur forests and eastern Chittagong and Chittagong Hill-Tracts forest. Along with the agricultural lands, each of the forest ecosystems is composed of numerous species of spider fauna of the country.
