Diagnosis

Grammostola inermis can be recognized by the presence of smooth setae on prolateral and retrolateral coxal faces of legs I–IV and retrolateral palpal maxillae; PB bearing a small black thorn on inner side and a group of two to four small thorns apical, RB with a long spine subapical; male palpal bulb pyriform with narrow mid-portion of the bulb base, PI and PS weakly developed, straight and short embolus ( Figure 4C, D ); two long and straight spermathecal receptacles ( Schiapelli and Gerschman 1961).

Distribution

Previously known from Catamarca (Belén) and the Argentinean Andean zone from Catamarca to Neuquén Provinces with no locality data ( Schiapelli and Gerschman 1961; Schmidt 1999). In this contribution ( Figure 5C ): south of Catamarca Province, central La Rioja, San Juan and Mendoza Provinces; also in San Luis and Córdoba Provinces (restricted to the mountain ranges), involving the regions of Monte, dry Chaco, Puna and High Andes. To the south, is present at the Neuquén Province, in the regions of Patagonic Steppe and Monte ( Figure 5D ).
