Thrixopelma lagunas sp. n., eine bisher unbekannte Vogelspinnenart aus Peru (Araneae: Theraphosidae: Theraphosinae)

Gunter Schmidt, Jan-Peter Rudloff ,2010

Thrixopelma lagunas sp. n. is the fourth species of the genus distributed in Peru. It is characterized by a prolonged embolus in the male (fig.4-5) and very simple receptacula seminis in the female (fig. 9). The scopula of metatarsus III extends over a third of the segment only. In T. pruriens Schmidt, 1998 it covers 2/3, in T. cyaneolum Schmidt, Friebolin & Friebolin, 2005 and in T. ockerti Schmidt, 1994, 1/2 of the metatarsus III. It differs by its dark brown colour from T. cyaneolum which shows a cyan brightness of carapace and extremities and from T. ockerti by its spermathecae which are pointed- caplike. The new species is closely related to T. pruriens also distri-buted in Peru.

Zur Kenntnis der Gattung Phormictopus Pocock, 1901 - einem Faunenelement der Grossen Antillen (Mygalomorphae: Theraphosidae: Theraphosinae)

Jan-Peter Rudloff ,2008

Hitherto the genus Phormictopus POCOCK, 1901 consisted of 14 species and 2 subspecies of which 5 were reported from South America. This article reduces the species number to 12. Five new species are decribed, 4 new synonyms declared, 3 nomina dubia (missing types), and 3 of the former species belong to other genera (now status “incertae sedis”). The distribution of the genus Phormictopus is restricted to the Greater Antilles.

Eine neue Brachypelma-Art aus Mexiko (Araneae: Mygalomorphae: Theraphosidae: Theraphosinae)

Jan-Peter Rudloff ,2008

In this paper a new species of Brachypelma from Veracruz, Mexico, Brachypelma kahlenbergi n. sp., is described. Males and females are almost entirely black with red orange setae on the dorsal face of the opisthosoma. The species described here is named in honour of Herwig KAHLENBERG, Berlin, Germany, who first recognized that it is an undescribed species of Brachypelma.

Eine neue Brachypelma-Art aus Mexiko, Brachypelma schroederi sp. n. (Araneae: Mygalomorphae: Theraphosidae: Theraphosinae)

Jan-Peter Rudloff ,2003

In this paper a new species of Brachypelma from Mexico, Brachypelma schroederi sp. n., is described. A division of the genus in two groups without any intention on systematics is proposed: the "emilia"-complex, containing colorfull spiders, and the "vagans"-complex consisting of species characterized by the more or less monotone coloration of their integuments.

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.

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.

Una nueva especie de Cyrtopholis de San Blas (Cienfuegos) - Cuba (Theraphosidae: Mygalomorphae) incluido una comparación entre Cyrtopholis gibbosus Franganillo 1936 y Cyrtopholis regibbosus Rudloff 1994

Jan-Peter Rudloff ,1995

En Febrero de 1992 el Doctor G. Scbmidt publico un trabajo sobre el genero Cyrtopholis, en el cual el rectifica la revision de Bryant, quien situada la Cyrtopholis gibbosus Franganillo 1936 en el genero Sphaerobothria . En su investigación el mismo utiliza el igual tipo de ejemplar que utilizara Bryant. Bryant determino su ejemplar procedente de San Bias como Cyrtopholis gibbosus Franganillo 1936. Teniendo en cuenta el articulo de Scbmidt y la propagación de esta conocida especie en Cuba llego a la conclusion de que no se trata de la especie descrita por Franganillo. La conclusión del trabajo de Bryant, de la comparación con la primera descripción y de los materiales obtenidos en las localidades me dan razon indudablemente que se trataba de un error. En Enero de este año se dio la posibilidad de realizar una expedición en el territorio de San Bias, alli se pudieron encontrar algunos ejemplares de la especie nombrada, facilmente pude llegar a la conclusion de que se trataba de otro tipo de ejemplar con la parte cefalica desarrollada, la cual describo a continuacion.
