MLP-14605 ♂ Holotype Argentina

Belen, Catamarca

February 1939 · col. Birabén

MACN-Ar 46347 ♀ Argentina

Near the type locality, Catamarca

Non-type female of Grammostola inermis, redescribed by Nicoletta et al. (2025) because the female Schiapelli & Gerschman described in 1961 could not be located in the collection.

Taxonomic History

1941
Grammostola inermis Mello-Leitão, 1941 Bücherl (1951) downgraded this species to Grammostola spatulata inermis. Schiapelli & Gerschman (1961) synonymised G. australis Gerschman & Schiapelli, 1948 with it and described a female. Nicoletta, Ferretti, Soresi & Pérez-Miles (2025) resurrected G. australis as a separate species on morphological and molecular evidence, redescribed this holotype, and noted that the 1961 female could not be located in the collection - they therefore redescribe a non-type female from near the type locality.
