On the types species of the New World dung beetle genus Canthidium Erichson, 1847 (Coleoptera: Scarabaeidae: Scarabaeinae), with an annotated checklist of species Author Cupello, Mario text Zootaxa 2018 2018-03-06 4388 4 451 486 journal article 30595 10.11646/zootaxa.4388.4.1 a884362d-a9f8-4cee-8cd4-dcf59a73ede2 1175-5326 1189072 7A57C29B-6B16-445E-A8D7-750C736E6B42 Canthidium ( Neocanthidium ) quadridens Harold, 1867 Canthidium quadridens Harold, 1867b : 73 [here transferred to the subgenus Neocanthidium ]. Type locality: Peru : Loreto : Mariscal Ramón Castilla: Pebas, the Upper Amazon River (“Oberes Gebiet des Amazorenstromes, Pebas (Bates!)”). Type material: Unknown number of syntypes (MNHN—ex Bates collection). Distribution: Peru ( Harold 1867b , 1869a ) [the geographical distribution of this species is very confusedly reported throughout the literature. Harold (1867b , 1869a ) clearly states his specimens were collected by Henry Walter Bates in Pebas, Peru . Without explanation, Gillet (1911) and Blackwelder (1944) cited the species only from Mexico and Martínez & Halffter (1986a) cited the species only from Bolivia . Here I decided to follow Harold’s original report since there is no evidence suggesting it is wrong. It is also noteworthy that neither Kohlmann (2003) nor Kohlmann & Solís (2006a) included C. quadridens is their studies of Mexican Canthidium ].
