Description of the male of Yabisi guaba (Araneae: Eresoidea: Hersiliidae)

Rheims, Cristina AAgnarsson, IngiAlayón Garcia, Giraldo

Hersiliidae is a relatively small spider family that is easily distinguished by the very long posterior lateral spinnerets. It is distributed worldwide and, although quite diverse in other zoogeographical regions, is represented by only 11 species in the Neotropics. Hersiliidae was recently revised and of the 11 species, three are known solely from one sex. Yabisi Rheims & Brescovit, 2004 includes only two species, one of which is known solely from the female. The genus is extremely rare and both species are known from only a few specimens. In this paper, the male of Yabisi guaba Rheims & Brescovit, 2004 is described and illustrated and an extended diagnosis is given for the genus. The male of this species is distinguished from its congener by the palps, with laminar embolus having the same width throughout its length and median apophysis narrow and distally rounded.(AU)
