Diagnosis

The female of this species has an epigyne similar to that in Asemonea pulchra , but the seminal ducts are clearly wider and copulatory openings hidden under heavily sclerotized flaps absent in A. pulchra (compare Fig. 5A View Fig with Fig. 5B View Fig and Fig. 5F View Fig with Wanless 1980: fig. 15g –h). Also the colouration of Asemonea pusilla sp. nov. is generally lighter than in the former species.

Etymology

The specific name is Latin, meaning ‘very small’, and refers to the size of this spider.
