Stenotarsus scissistylus gen. et sp. n. (Theraphosidae: Theraphosinae), eine Vogelspinne aus Französisch Guyana

Marc Tesmoingt, Gunter Schmidt ,2002

The genus Stenotarsus gen. nov. closely related to Aphonopelma Pocock, 1901 is established for South American species formerly desgnated as Eurypelma group A according to SIMON 1892 where metatarsus I containing many spines is as long as or not as long as tibia I. It differs from Aphonopelma by a procurved fovea (fig. 13), urticating hairs of type 1 and 3, a distally widened embolus (fig. 3) and spermathecae widely fused (fig. 19 - 21) with two little heads of different shape. S scissistylus is a medium-sized species. It's embolus appears deeply rutted (fig. 4) The relations to other species living in the Guyanas, North Brazil and Venezuela are discussed.

The first mygalomorph spider without spermathecae: Sickius longibulbi, with a revalidation of Sickius (Araneae. Theraphosidae, Ischnocolinae)

Rogério Bertani, Pedro Ismael da Silva Júnior ,2002

The monotypic Brazilian genus Sickius Soares & Camargo 1948 is revalidated, rediagnosed, and tentatively transferred to the Ischnocolinae. The formerly unknown female of S. longibulbi Soares & Camargo 1948 is found to lack spermathecae. This unusual genital feature, not found in any other mygalomorph spider species, is described and discussed.

Revision of the African genera Pterinochilus and Eucratoscelus (Araneae, Theraphosidae, Harpactirinae) with description of two new genera.

Rogério Bertani ,2001

The 16 species of the South American theraphosine genera Vitalius Lucas, Silva Junior & Bertani, 1993; Nhandu Lucas, 1981; and Proshapalopus Mello-Leitfio, 1923 are described, keyed, illustrated, diagnosed, and a cladistic analysis using 30 terminals and 35 characters is provided. Vitalius comprises nine species ofwhich 4 are newly described: Vitalius paranaensis, Y. longisternalis, Y. buecherli, andy' lucasae.

Fabian Vol ,2001

I give a summary of the following description of Metriopelma ledezmae to be published in its full form in the book of Jean Michel VERDEZ and Frédéric CLETON, Les mygales, Editions Philippe Gerard. This should be out in September in 21 x 29.7 format, and with over 200 colour photographs with more than 130 species, constitutes no doubt the best book in French on these spiders.

A new species of tarantula spider (Araneae, Mygalomorphae, Theraphosidae) from the Cayo District of Belize

Steven B Reichling, Rick C. West ,2000

A new species of theraphosid spider, Citharacanthus meermani sp. nov., is described. It was collected in the foothills of the Mountain Pine Ridge and the Vaca Plateau, Cayo District, Belize. It is distinguished from congeners by filiform plumose setae on the basoprolateral faces of both trochantera and femora I-II, and the presence of five prominent keels on the apical division of the male embolus.

Description de Bonnetina cyaneifemur, gen. n. & sp. n. (Araneae, Theraphosidae, Theraphosinae) du Mexique

Fabian Vol ,2000

In August of this year was André Leetz send me a mature male and a few molts a remarkable Theraphosidae its femurs and dark blue bristle on the abdomen, a deep red. It was determined that a spider had been circulating for some years among collectors as the "Schizopelma sp." Fortunately, among the few exuviae accompanying the male there were two female.

A review of primary and secondary sexual characters of the male was soon revealed that this tarantula belonged to a new genus. The shape of the spermatheca confirmed quickly.

I did not have any data on the origin of this spider apart from the fact that came from Mexico. However, it is only by a happy coincidence, this summer I collected Theraphosidae few in the state of Colima on the Pacific coast of Mexico. Among these included a subadult male with the same characteristics as that made me André achieve Leetz especially this dark blue shade remarkable on femurs. With this information so I could start the following description.

Eine seltsame Eucratoscelus-Art aus Ostafrika (Araneae: Mygalomorphae, Theraphosidae, Harpactirinae)

Gunter Schmidt, Jurgen Gelling ,2000

A new species of Eucratoscelas POCOCK, 1898, E. lenuitibialis sp. nov., is described. It differs from the two other species of this genus by a normal, not thickened tibi a IV and rounded secondary receptacula seminis instead of more or less elongated ones. lt is very similar to species of Pterinochilus Pocock, 1897. A revised key of the Harpactirinae is provided.

Biochemical identification of Selenocosmia hainana sp. nov. from south China (Araneae, Theraphosidae)

Liang Songping, Peng Xianjin, Huang Renhuai, Chen Ping ,1999

By means of reverse phase and ion-exchange high performance liquid chromatography (HPLC), matrix-assisted laser desorption/ionization time-of-flight mass spectrometer (MAIDI-TOF MS) and amino acid sequence analysis of peptides, the venom from the spider found in Tongshi county, Hainan province of south China was analyzed and compared with that of the spider Selenocosmia huwena. Evident differences were found in the HPLC chromatograms and MAIDI-TOF spectrum of the venom from the two spiders. The amino acid sequences of the main neurotoxin from the two spiders are also different. The results indicated that, although the two spiders are similar to each other morphologically, they should belong to different species. The spider from Tongshi, Hainan was identified as a new species and was named Selenocosmia hainana sp. nov. Type specimens are deposited in College of Life Sciences, Hunan Normal University.

Une nouvelle espece d'Avicularia du Bresil: Description d'Avicularia braunshauseni (Araneae, Theraphosidae, Aviculariinae)

Marc Tesmoingt ,1999

This variety has been captured by André Braunschausen Santarem, which lies between Macapa and Manaus in Brazil. This spider can reach amazing dimensions to say the least as Jean-Michel Verdez, colleague and friend, showed me at his home. This tarantula is aggressive and handling must be done with caution. Fast, it must, given its size, make astounding jumps. André Braunshausen indicates that the specimens were captured on the edge of a trail, in the trees and shrubs and that he has a male to conduct breeding. The name of this Avicularia species is braunshauseni. Finally, note that this species is still not widespread in France
