Taxon classification Animalia Araneae Nemesiidae

Genus Sinopesa Raven & Schwendinger, 1995

Type species.

Sinopesa maculata Raven & Schwendinger, 1995, by the original designation.

Diagnosis.

Sinopesa, like Raveniola, differs from Hermacha and Entypesa by lacking serrula and metatarsal preening combs and by possessing two enlarged retroventral spines in males and divided receptacles in females. As in members of Raveniola, the PMS in Sinopesa are reduced in size and even lost in some species - a condition which has never been observed in Hermacha and Entypesa . Sinopesa differs from its close relative Raveniola by a thin and less developed scopula and by the presence of a well-developed male intercheliceral tumescence (which is less developed in Raveniola and completely lost in all Chinese members of this genus).

Composition.

Six species - Sinopesa chengbuensis (Xu & Yin, 2002) (China), Sinopesa chinensis ( Kulczyński, 1901) (China), Sinopesa ninhbinhensis sp. n.
