Diagnostic Features.
This new species is very similar to
Clubiona corrugata
Boesenberg and Strand,
1906
but differs from the latter in terms of (
1
) sharply pointed and sickle-shaped embolus, (
2
) seminal duct narrowly V-shaped posteriorly, (
3
) cymbium parallel-sided medially seen ventrally and bears a long spine prolaterally, (
4
) RTA slender with a short, pointed and slightly curved tip and hump midprolaterally forming two shallow cavities, (
5
) palpal tibia with long thin hairs extended to threefourth length of RTA, and (
6
) leg spination.
