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.
