Arachnida, Araneae ) 1985 . The Journal of Arachnology 13:399 ON THE CHILEAN SPIDERS OF THE FAMILY PALPIMANIDAE (ARACHNIDA, ARANEAE ) Only two species of palpimanid spiders have previously been recorded fro m Chile. Anisaedus pellucidas Platnick is known only from Antofagasta an d Atacama provinces in northern Chile, and (judging by the presence of a translucent embolar flange) seems most closely related to Anisaedus rufus (Tullgren) of northwestern Argentina (Platnick, N . I. 1975. Amer. Mus. Novit. , 2562:1-32). Two localities can now be added to the only previous records of A . pellucidas from Atacama province (Platnick, N . I. 1977. J. Arachnol., 3:203-205): 40 km S Copiapo (700 m), 23-25 October 1983 (L. E. Pena G.), 1 male, and between El Transito and Pinte (1100-1600 m), 25-27 October 1980 (L . E. Pena G.), 1 male, 1 female, all in the American Museum of Natural History (AMNH) . The second species, Otiothops lanus Platnick, is known only from the Quebrada de la Plata in Santiago province . It differs from all other previously known Otiothops in having relatively small posterior median eyes separated b y almost twice their diameter ; this discrepancy was perhaps responsible for the original description of the species as a Fernandezina (Zapfe, H. 1961. Invest. Zool. Chilenas, 7 :141-144) . It was of particular interest, therefore, to discove r (among material recently sent to the AMNH by Dr . Luis E. Pena G.) a male of a second Chilean species of Otiothops from Maule province . The new specie s resembles O. Lanus, rather than other Otiothops, in eye pattern. Although Figs. 1, 2 .-Left male palp of Otiothops maulensis: 1, ventral view ; 2, retrolateral view. 1985 . The Journal of Arachnology 13:400 outgroup comparison with the Stenochilidae indicates that the separated posterio r median eyes are plesiomorphic, the distolaterally originating and distally bifid embolus suggests that the new taxon is indeed the sister species of O . Lanus. This work was supported by grants BSR-8312611 and BSR84-06225 from the National Science Foundation . The illustrations are by Dr . M. U. Shadab. Otiothops maulensis, new species Figs. 1, 2 Type.—Male holotype from W of Cauquenes, Maule, Chile (May 1984, L . Irarrazaval), deposited in AMNH . Etymology.—The specific name refers to the type locality. Diagnosis.—Males can be distinguished from those of all other Otiothops except O. Lanus by the widely separated posterior median eyes, and from thos e of O. Lanus by the proximally bulging embolus (Figs. 1, 2). Male.—Total length 3 .28 mm. Carapace 1 .55 mm long, 1 .15 mm wide . Femur I 1 .19 mm long, 0.54 mm wide. Cephalic area moderately elevated . Posterior median eyes separated by twice their diameter . Abdomen with scattered brownis h purple patches on pale brown background. Claw tufts reduced to few seta e surrounding onychium . Palp with globose tibia, long narrow cymbium, an d retrolaterally prolonged bulb almost entirely occupied by reservoir. Embolus originating retrolaterally near tip of bulb, distally bifid, with proximal lob e translucent, distal lobe sharply pointed (Figs . 1, 2). Female.—Unknown.

LABORATORY INFECTION OF GARYPUS CALIFORNICUS (PSEUDOSCORPIONIDA, GARYPIDAE) WITH NEOAPLECTANID AND HETERORHABDITID NEMATODES (RHABDITOIDEA ) Entomogenous nematodes of the genera Neoaplectana and Heterorhabditis are being commercially produced as biological control agents for use against a variet y of insect pests (Poinar, Jr., G. .0. 1983. Proc. Tenth Int . Congr. Plant Prot . 2:751-758) . Tests are being conducted to examine the ability of these nematode s to infect non-insect representatives of the Arthropoda . The present study was conducted to determine if members of these nematode genera could infect representatives of the Pseudoscorpionida under laboratory conditions ..

College, Kushinagar, U.P., 2Department of Zoology, University of Rajasthan, Jaipur-302004, Rajasthan, 3Department of Zoology, Deendayal Upadhyay University of Gorakhpur-273009, U.P., India. Abstract The present article deals with the faunal diversity of eleven families of spiders, viz. Palpimanidae, Pimoidae, Psechridae, Psilodercidae, Segestriidae, Selenopidae, Sicariidae, Stenochilidae, Symphytognathidae, Tetrablemmidae and Theridiosomatidae (Araneae: Arachnida) in different Indian states and union territories. None of the spider species of these families is recorded from following Indian states: Arunachal Pradesh, Chhattisgarh, Haryana, Mizoram, Telangana and Tripura and among the union territories they are reported from Andaman, Nicobar Islands, Jammu & Kashmir, Lakshadweep and Puducherry. Three families Tetrablemmidae, Selenopidae and Psechridae are represented by 10, 8 and 7 species, respectively. Other families are very poorly reported, 5 species in Segestriidae, 4 species each in Palpimanidae and Pimoidae, 3 species each in Psilodercidae and Stenochilidae, 2 species in Sicariidae while single species each in Symphytognathidae and Theridiosomatidae. Maximum number of spider species of these families were recorded in Tamil Nadu (16 species) followed by Kerala and Uttarakhand (10 species each), Maharashtra (9 species), Karnataka (8 species), and less number in other states. Endemism of these families is very high (62.5%), out of 48 species of all these families recorded in India, 30 species are strictly endemic.

  • 129 Malta, December 2005
    The Central Mediterranean Naturalist 4(2): 121 - 129 Malta, December 2005 THE CURRENT KNOWLEDGE OF THE SPIDER FAUNA OF THE MALTESE ISLANDS WITH THE ADDITION OF SOME NEW RECORDS (ARACHNIDA: ARANEAE). 1 2 3 David Dandria , Victor Falzon & Jonathan Henwood ABSTRACT The current knowledge of the spider fauna of the Maltese Islands is reviewed. Four species are recorded for the first time, and information is given about the banded argiope, Argiope trifasciata, which is thought to be a recently introduced species. An updated checklist of the spider fauna of the Maltese Islands is also provided. INTRODUCTION The recorded spider fauna of the Maltese Islands hitherto comprises 137 species in 31 Families, including seven endemic species. Only one species belongs to the suborder Orthognatha - the endemic trapdoor spider Nemesia arboricola, first recorded by R.I. Pocock in 1903, and recently re-described by Kritscher (Kritscher, 1994). Another nemesiid (N. macrocephala) was recorded by Baldacchino et al. (1993), but after re-examination of the specimens in the light of Kritscher's 1994 redescription, this was found to be based on misidentification and the material was assigned to N. arboricola (Dandria 2001). The other 136 species belong to the sub-order Labidognatha, and their occurrence was documented by Cantarella (1982), Baldacchino et al. (1993), Bosmans & Dandria (1993) and Kritscher (1996). The largest family is that of the ground spiders, Gnaphosidae, numbering 21 species including the endemic Poecilochroa loricata Kritscher 1996. The jumping spiders, Salticidae, which were the first Maltese spider family to receive serious attention in Cantarella's 1982 study, are represented by 19 species, among which is the sub-endemic Aelurillus schembrii Cantarella 1983, which has so far only been recorded from Malta and Sicily.

Koedoe 48(1): 77–86. Pretoria. ISSN 0075-6458. The Swartberg Nature Reserve is situated in the Large Swartberg mountain range, in the Oudtshoorn district of the Western Cape Province. Spiders were collected from the reserve over a 10-year period. This is one of the inventory projects of the South African National Survey (SANSA) for spiders of the Succulent Karoo Biome. A total of 45 fam- ilies comprising 136 genera and 186 species were collected, all which are new records for the area. This represents about 9.4 % of the total known South African spider fauna. Of the spiders collected 142 species (76.5 %) were wanderers and 44 (23.5 %) web dwellers. The plant dwellers comprised 43.3 % of the total number of species and the ground dwellers 56.7 %. The Gnaphosidae was the most diverse family represented by 33 species, followed by the Salticidae with 23 and Thomisidae with 15. Ten species are possibly new to science and the Filistatidae is a first record for South Africa. An anno- tated checklist with information on the guilds, habitat preference and web types are pro- vided.

PLATNICK1 & ROBERT J. RAVEN2 1Division of Invertebrate Zoology, American Museum of Natural History, Central Park West at 79th Street, New York NY 10024 USA. E-mail: [email protected] 2Queensland Museum, PO Box 3300, South Brisbane, Queensland 4101, Australia. E-mail: [email protected] Spider systematics has a history that reaches back over 250 years, to the publication of Carl Clerck’s Svenska Spindlar (Clerck, 1757). Linnaeus (1758), in the famous 10th edition of his Systema Naturae that was published the following year (and which serves as the starting point for the rest of zoological nomenclature), recognized only 39 species of spiders, worldwide, even though he knew (and cited) Clerck’s book. Clerck had already recognized more species than that from Sweden alone, and (unlike Linnaeus) provided good, color illustrations of them, often including even drawings of the male palps. So it is not surprising that arachnologists take Clerck, rather than Linnaeus, as their starting point. The most current version, 13.5, of the World Spider Catalog (Platnick, 2013) lists a total of 43,678 currently valid species, placed in 3,898 genera and 112 families (Table 1). The database version of the catalog has recently been updated to include the information from version 11.0 of the text catalog (previously, only the information from version 8.5 was accessible in database form).

  • History and Advances of Spider Studies in the Caucasus
    History and advances of spider studies in the Caucasus Yuri M. Marusik It is an update of the lecture given in Blagoevgrad in 2005 History was divided into 4 periods/stages 1) Beginning 1878-1938 2) Pre-Dunin 1939-1974 3) Dunin’s 1974-1998 4) Modern 1999- … Now one more period should be added. Guess what? First period: 1878 1789 First was Samuel G. G. Gmelin (1744-1774), in whose book 3 species were described in Kalmykia (not coincides with modern boundaries). Passed away in captivity in Daghestan. Victor I. Motschulsky Started to collect when he was army officer during the Caucasian War, visited Tiflis. Described 2 species from “Kalmykia” in 1849. First period: Collecting efforts: E. Keyserling (visited Northern Persia in 1859, and collected there). First detail publication by L. Koch (1878): 25 species of spiders, as well as scorpions, pseudoscorpions, Opiliones and solifuges. Contribution were made by Russians: A. Kroneberg, E. Wierzbitski, A.M. Zavadski, S.A. Spassky, and foreign arachnologists: W. Kulczyński, E. Simon, T. Thorell. Affinities: all authors lived outside the Caucasus (except Spassky); 206 species reported and described. Second period: Start by series of papers by Charitonov (1939) and activities of Georgian arachnologist Tamara S. Mcheidze. Another contributors A.S. Utotchkin (Perm) and V.E. Pitchka (Kiev). I had a pleasure to mee Tamara Mcheidze when visited Georgia in 1982. She gave me a bottle of Georgian brandy (we say Коньяк)? And it was consumed with other collegues-arachnologists in Leningrad. Affinities: slow and low growth of knowledge. Third period: 1974-1998 I count it from Peter Dunin (1952-1998) from Baku who started publishing papers since 1974.
