Diagnosis

Grammostola chalcothrix can be recognized by the following combination of characters: presence of long spiniform setae on prolateral and retrolateral coxal aspects of legs I–III, prolateral coxae IV and retrolateral palpal maxillae; male palpal bulb pyriform with PI developed and PS well developed, slightly curved and very long embolus ( Figure 4A, B ); two long and curved spermathecal receptacles ( Schiapelli and Gerschman 1961).

Distribution

Previously known from Santa Fé (Rosario) and Córdoba Province with no locality data ( Schiapelli and Gerschman 1961; Schmidt 1999). In this contribution ( Figure 5A ): southern Chaco Province, central Santiago del Estero Province, Córdoba Province (mountain ranges and meadows) and southern Santa Fé Province, comprising the regions of dry Chaco, Espinal and Pampa. To the west, it is also present in La Rioja and San Juan Provinces, at the limits of dry Chaco and Monte regions ( Figure 5B ).
