monomorphica Cazorla & Spinelli, 2015: 175 (macho, hembra). Localidad tipo: Argentina, Neuquén, laguna Epulaufquen, 36°50'9.49"S, 71°1'1.08"W . HT M (MLPA). Distr.- Argentina (Neuquén: type locality. Río Negro: Parque Nacional Nahuel Huapi, laguna los Clavos, 41°02'48.6''S, 71°49'33.9''W, 1194 m). Refs.: Cazorla & Spinelli, 2015: 175.
Diagnosis: the only Patagonian species of Stilobezzia (Acanthohelea) without normal secondary sexual dimorphism, and both sexes have a basal spine on tarsomere 1 of the hind leg. Males with gonostylus stout proximally, distal 2/3 curved, apical 1/3 abruptly tapered, tip slender and sharply pointed. Females scutum dark brown except humeral pits and mesal region yellowish, and small, greatly unequal-sized and globular spermathecae.
