Einige Anmerkungen zur Gattung Citharacanthus Pocock, 1901 (Theraphosinae: Theraphosidae: Mygalomorphae)

Jan-Peter Rudloff ,1998

This is an attempt, to characterize the genus Citharacanthus Pocock, 1901, with todays knowledgement. For this, we look at the historic developement within the systematic. A key to the today known species will be developed. Citharacanthus longipes niger FRANGANILLO, 1931 will be revised and get the status of a own kind. The future name is Citharacanthus niger FRANGANILLO, 1931, and Cyrtopholis sargi STRAND, 1907 is in future Citharacanthus sargi (STRAND, 1907). Also we discuss the position of Citharacanthus spinicrus (LATREILLE, 1818) this species has to be categorized as "nomen dubium incertae sedis". At the end we talk about the close relationships within their kind, for future work there is a key to easier identify both sexes.

A diminutive new species of Acanthopelma from Belize (Araneae: Theraphosidae)

Steven B Reichling ,1997

A new species of Acanthopelma (Araneae: Theraphosidae) from northern Belize is described, and is among the smallest theraphosid spiders known. The new taxon is distinguished from congenerics by an incrassate palpal tibia, preapical embolar process and unmodified tibial spur in males, and a unique abdominal pattern in females. Both sexes possess unusually short medial segments of the posterior lateral spinnerets. Data on meristic and morphometric character variation and natural history notes are also presented.

Eine weitere Tapinauchenius-Art aus Ecuador: Tapinauchenius subcaeruleus n. sp. (Arachnida: Araneae: Theraphosidae: Aviculariinae)

Stefan Bauer, Daniele Antonelli ,1997

The new Tapinauchenius species, T subcaeruleus n. sp. , is very similar to T elenae Schmidt 1994, but differs in some peculiar features of its coloration. As in T elenae the receptacula seminis terminate in some ovoid structures instead of a knob as in other species of this genus.

A new species of Crypsidromus from Belize (Araneae, Mygalomorphae, Theraphosidae)

Steven B Reichling ,1997

A new species of Theraphosidae, Crypsidromus gutzkei, is described (from the male only ) from northern Belize . Unique coloration in combination with pedipalps of intermediate length distinguishe s C. gutzkei from all congeners . Character states proposed as diagnostic for males of Crypsidromus Ausserer 1871 and Metriopelma Becker 1878 are combined in the male of this new species, supporting the maintenance of Metriopelma in the synonymy of Crypsidromus.

Revision der Gattung Holothele Karsch, 1879 nebst Aufstellung einer neuen Gattung Stichoplastoris gen. nov. (Araneae, Theraphosidae) und Wiedereinsetzung einiger weiterer Gattungen der Mygalomorphae

Jan-Peter Rudloff ,1997

The genus Holothele KARSCH, 1879 is revised. Stichoplastoris gen. nov. is established to Substitute Stichoplastus SIMON, 1889 which will not be available in future. Schismatothele KARSCH, 1879 will be revaluated as a genus of Theraphosidae. Euthycaelus SIMON, 1889 is also revaluated but placed into the family of Barychelidae. Proshapalopus MELLO-LEITAO, 1923 is removed from synonymy with Stichoplastus SIMON, 1889. Hemiercus SIMON, 1889 and Schismatothele KARSCH, 1879 are removed from synonymy with Holothele KARSCH, 1879. A key is added to all actually known species of Holothele as well as detailed descriptions of Holothele sericea SIMON, 1903 and Schismatothele lineata KARSCH, 1879. Diagnosis and drawings are given to qualify even non-specialists for identifying these taxa.

Chaetopelma karlamani sp. n., (Araneida: Theraphosidae: Ischnocolinae) eine Vogelspinne aus Nord-Zypern

Patrick Vollmer ,1997

A new Chaetopelma-species from north-cyprus (Besparmak-mountain) is discribed. It differs from other species of this genus by two very seperate receptacles who thickin at the end, the structure of palpal bulb and a extrem short bodysize. Ischnocolus gracilis (AUSSERER, 1871) is transfer to the genus Chaetopelma (AUSSERER, 1871) and Chaetopelma aegyptiacum (AUSSERER, 1871) is synonymy with Chaetopelma gracile.

Description de Brachypelma annitha n. sp. et de Brachypelma hamorii n. sp. mâles et femelles, nouvelles espèces proches de Brachypelma smithi (Cambridge, 1897) du Mexique

Marc Tesmoingt, Frédéric Cleton, Jean Michel Verdez ,1997

Brachypelma annitha n.sp. and Brachypelma hamorii n.sp. (Mexico) show morphological differences with B. smithi although visually closer to the latter. Spermathecae and copulatory organs of males are food for thought. Indeed, if the spermathecae of hamorii are distinct, those of annitha are not. On the other hand, in the copulatory organs and tibial apophysis, the opposite is true: where the bulbs and tibial apophysis of annitha are distinct from smithi, in contrast those of hamorii are similar to the latter making it possible to consider including these as a subspecies in the genus.

Theraphosidae of the Mojave Desert west and north of the Colorado River (Araneae, Mygalomorphae, Theraphosidae)

Thomas R Prentice ,1997

Two new species of Aphonopelma from the Mojave Desert are described, A. joshua and A. mojave. Four nominal species, Aphonopelma iodium (A. iodius), A. melanium (A. melanius), A. angusi, A. nevadanum, described from the Mojave Desert and the Great Basin are treated as a single species ; Aphonopelma iodium (Chamberlin 1939) is proposed as the species name since it is one of two possible senior synonyms (the other, A. melanium (A. melanius) in the same publication) and is the specific nam e of the first Theraphosidae to be described from the Mojave Desert ; A. iodium is redescribed. Generic, subgeneric, and specific characters previously used to separate Aphonopelma are reviewed. Aphonopelma is redefined; Clavopelma is removed from the synonymy of Aphonopelma. The status of the following eight species described prior to 1939 with type localities either in the United States or in Baja, Californi a is discussed: Aphonopelma californica, A. leiogaster (Doleschall), A. steindachneri (Ausserer), A. rusticum, A. marxi, A. helluo (Simon), A. rileyi (Marx), and A. pseudoroseum (Strand). Aphonopelma steindachneri , A. rusticum, A. marxi, and A. helluo are considered as valid species ; A. californica, A. leiogaster, A. rileyi, and A. pseudoroseum are considered as nomina dubia.

Haplocosmia nepalensis gen. et sp. n., die erste Vogelspinne aus Nepal (Araneida: Theraphosidae: Selenocosmiinae)

Gunter Schmidt, Volker von Wirth ,1996

The new genus Haplocosmia differs from all other genera of Selenocosmieae by an undivided spermatheca resembling that of Haplopelma and the following combination : Third unpaired claw on tarsus IV, thornlike setae on chelicerae prolaterally, scopula on tarsi I,II parted, III divided by thin hairs, IV divided by setae, procurved fovea, procurved front row of eyes and butterknife?like stridulating setae on prolateral surface of maxillae.
