Abstract
The genus Orsinome was established by Thorell in 1890 with O. vethi (Hasselt, 1882) as the type species. It presently comprises 17 described species (World Spider Catalog 2018), of which two are known from India: O. armata Pocock, 1901 and O. listeri Gravely, 1921 (World Spider Catalog 2018). While studying spiders from the Indian Himalayas and north-East India, we examined the type specimens of Labulla nepula Tikader, 1970 and found it to be misidentified and placed erroneously in the family Linyphiidae Blackwall, 1859. Moreover, Orsinome listeri Gravely, 1921 described from the Eastern Himalayas was also found to be indistinguishable from O. vethi (Hasselt, 1882). In this paper, we provide detailed illustrations of the types of L. nepula Tikader and O. listeri Gravely and synonymize it with O. vethi (Hasselt, 1882) based on the cheliceral dentition and genital morphological characters.
