Eine neue Vogelspinne aus Neu Guinea: Selenotypus arndsti sp. n. (Araneida: Theraphosidae: Selenocosmiinae)

Gunter Schmidt, Volker von Wirth ,1991

Since the beginning of 1989 a tarantula from New Guinea is imported to Germany, here and in England is sold under the name Selenocosmia lanipes Ausserer 1875. It differs from the species of the genus by the Selenocosmia stridulations organ, the eye position and the relative eyes Grobe. This is an undescribed species of the previously monotypic Genus Selenotypus Pocock 1895, of which only the genotype, Selenotypus plurnipes Pocock 1895, the groBte Australian spider species from Queensland, was known. Due to the finding of a second type, the genus diagnosis Mmust be extended.

Notes on some mygalomorph spiders in the Musée Royal de l'Afrique Centrale (Dipluridae, Hexathelidae, Ctenizidae: Araneae)

Robert John Raven ,1983

Diagnoses (with scanning electron micrographs of relevant structures) of genera of Dipluridae (Lathrothele, E11typesa), Hexathelidae (Heterothe/e) and Ctenizidae (Aporoptychus) in the Musee Royal de l'AJirique Centrale are given with notes on some species. Macrothele darche11i Benoit, 1966 is transferred to Heterothe/e Karsoh. Relationships of those genera are discussed.

Arañas terafosidas de Costa Rica (Araneae, Theraphosidae). IV. Generos Metriopelma y Cyclosternum, incluyendo especies de Panama

Carlos E. Valerio ,1982

Four new species are described from Costa Rica and Panama. Metriopelma zebrata Banks is redescribed, its female being new to science. Cyclosternum fasciatus, new combination, is discussed. M. morosus Banks is reduced to synonymy of M. zebrata. An English Appendiz with keys, diagnosis and explaination to figures is included.

Arañas terafósidas de Costa Rica (Araneae: Theraphosidae). III. Sphaerobothria, Aphonopelma, Pterinopelma, Citharacanthus, Crypsidromus y Stichoplastus

Carlos E. Valerio ,1980

Thirteen species of theraphosid spiders ("tarantulas") are described as new. Sphaerobothria hoffmani and Aphonopelma seemannz are redescribed and the male 01" S. seemanni is described for the first time . It is argued that the genera discussed here, which are traditionally placed in separa te subfamilies (Grammostolinae and Isehnocolinae) should be grouped . Common features to these genera are the shape of the bulb (distally atenuated and curved ventrally), spermatheea divided in two portions by a deep noteh, and coxa 1 with anterior side covered by conic spinules. The feature formerly used to separa te the two groups is not consistent within genera. Keys, diagnosis and explanations to figures are included in an English Appendi x.
