Comments . This species was described from Argentina based on a female. The description is very brief and does not provide any essential details like the type of calamistrum, or the shape of the cribellum and epigyne. Types could not be located by Lehtinen (1967) , who suggested it belonged either to Metaltella Mello-Leitão, 1931 (Desidae) or Geoldia Keyserling, 1891 ( Titanoecidae ). The latter genus and even family are unknown in Argentina so far (WSC 2019).
