Ballarin, Francesco & Li, Shu-Qiang, 2015, Three new genera of the family Nesticidae (Arachnida: Araneae) from Tibet and Yunnan, China, Zoological Systematics 40 (2), pp. 179-190 : 183

Genus Nescina gen. nov.

Type species: Nescina minuta sp. nov.

Etymology. The generic name is an arbitrary combination of letters inspired by the word " Nesticus ", the nominal genus of the family Nesticidae . The gender is feminine.

Diagnosis. The new genus is diagnosed by the remarkably small size, the elevated cephalic area clearly separate from the prosoma, the flat terminal apophysis with a laminar and a small hook-like processes and by the simple, hooked shape of the paracymbium. The ventrally flat appearance of the palpal bulb also contributes to make the new genus peculiar within the Nesticidae . The general shape of the conductor and its elongated lamina recalls the similar structure present in Hamus gen. nov. although all the other characters clearly identify them as different genera ( Figs 1B and 3B ). The epigyne appearance and shape of the long, twisted insemination ducts are diagnostic for the female and are unique within the family.

Distribution. China (Yunnan).
