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

Abstract

ABSTRACT. 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.

Inventario rápido de las arañas (Arachnida: Araneae) del refugio de vida silvestre El Cañón del río Gurabo, República Dominicana

“…representa el primer registro de este género para el norte de la República Dominicana; los registros previos, todos correspondientes a la especie endémica Pozonia andujari Alayón, 2007, provienen de las provincias Peravia, San Juan, San José de Ocoa y La Altagracia (Alayón García, 2007;Alayón García et al, 2011). Por otro lado, Y. guaba es una especie endémica, muy rara, de la que solo se han colectado tres ejemplares, en las provincias Pedernales y Montecristi (Rheims y Brescovit, 2004;Rheims et al, 2014), ampliándose su distribución conocida con el actual registro.…”
