§ Ancognatha vulgaris Arrow, 1911

Ancognatha vulgaris Arrow 1911b: 169 (Panama–Peru)

Distribution. French Guiana: Duranton 2011: 17 (?). Brazil: Endrödi 1985a: 161; Ratcliffe 2003: 45; Moore et al. 2018b: 119. Venezuela: Endrödi 1966a: 382; Moore et al. 2018b: 119. Other: Arrow 1911b: 169 (Panama–Peru), 1937b: 6 (Colombia, Panama, Peru); Blackwelder 1944: 250 (Colombia, Panama, Peru); Endrödi 1966a: 382 (Brazil Amazonas (Nauta) [> Peru!], Bolivia, Colombia, Costa Rica, Ecuador, Panama, Peru), 1985a: 161 (Bolivia, Colombia, Costa Rica, Ecuador, Panama, Peru); Ratcliffe 2003: 45 (Brazil/Bolivia–Costa Rica); Ponchel 2011 (not mentioned); Dupuis 2016b (not mentioned); Moore et al. 2018b: 119 (Bolivia, Colombia, Costa Rica, Ecuador, Panama, Peru).

Note 1. Arrow (1911b: 169) states in his description of Ancognatha vulgaris that “it ranges from Panama to Peru and the Upper Amazons (Nauta).” Based on this statement, Endrödi (1966a: 382) subsequently places Nauta in the Brazilian state of Amazonas. In fact, Nauta is a town situated on the Upper Amazon in the Peruvian region of Loreto, well away from the border with Brazil. The records for Brazil in Endrödi (1985a: 161), Ratcliffe (2003: 45) and Moore et al. (2018b: 119) may well be based on this error.

Note 2. Duranton (2011: 17) notes he saw no definite specimens of Ancognatha vulgaris from French Guiana, and the species is not mentioned in the checklists for French Guiana by Ponchel (2011) and Dupuis (2016b). We have not seen any specimens from Suriname and are unaware of any other records from the research area. This species appears to be restricted to northwestern South America and the southern part of Central America.
