Fairmaire and Germain (1859) described the species based on a single specimen ( Fig. 73 ) from Chile. Although it is not impossible that the species occurs in Chile, it has never been reported as being collected in that country since. Thus, it is probable that the holotype was incorrectly labeled. Bruch (1912) recorded A. nanus for Argentina.

Belon (1902) described A. latericius ( Fig. 72 ) based on a single specimen from Bolivia. Comparing the original description of this species with that of A. nanus , as well as photographs of the holotypes, it is not possible to separate it from the latter.

Breuning (1939) described Atimuropsis irregularis based on a single specimen from Brazil (Pernambuco), and Breuning (1940) described Adetus gracilis based on syntypes from Brazil (Ceará). Breuning (1940) provided two dimensions, indicating he had, at least, two specimens (“Länge 7–9 mm; Breite 12 ⁄ 3 – 21 ⁄ 4 ”), but he pointed out: “Typ von Brasilien: Cearà im britischen Museum.” The available informa- tion is contradictory because Breuning (1971) affirmed that the species was described based on a single specimen. Breuning (1971) also provided a new record for A. gracilis : Brazil (Pernambuco). Martins and Galileo (2003) correctly synonymized P. gracilis ( Fig. 75 ) with P. irregularis ( Fig. 74 ). However, the original descriptions, as well as photographs of the types do not allow separation of A. irregularis from A. nanus .
