Middle American Synemosyna (Araneae: Salticidae), a key and description of a new species

Abstract

A key and distribution map to the five Synemosyna species of Middle America (Mexico to Panama) are presented. Only S. americana is non‐endemic to this area, its range extends into South America. S. ubicki n. sp., and the previously undescribed male of S. maddisoni are described. S. ubicki is remarkable in lacking the prosomal and opisthosomal constrictions usual in this genus. These constrictions greatly contribute to the antlike appearance of those species which have them.
