Stenoterommata iguazu
Stenoterommata iguazu is a species of mygalomorph spiders of Argentina, named after its type locality: Iguazú, Misiones.[2] Females are distinguished from other species in the genus, except S. platense, by the 2 + 2 spermathecae; from S. platense, they are distinguished by the outer spermathecal lobe having a single receptaculum. Males are distinguished from other species, except S. platense, by having a thin, well-sclerotized embolus and the bulbal duct with an even curvature; from S. platense, by the sudden tapering apical portion of the bulbal duct and the slightly smaller size.
