Canthidium (Canthidium) moestrum Harold, 1867

Canthidium moestrum Harold, 1867a: 37 [here transferred to the subgenus Canthidium ]. Type locality: Brazil (“ Brasilien oder Columbien”; see discussion below). Type material: Unknown number of male syntypes (probably at least some of them in MNHN—ex Frédéric Tarnier collection, via Jules Desbrochers des Loges collection). Distribution: Brazil, Argentina, and Uruguay ( Harold 1867b, Martínez & Halffter 1986a) [although Harold (1867a) had originally said that he did not know whether his specimens were collected in Brazil or Colombia and, later ( Harold 1867b), stated that he had examined new specimens collected in southern Brazil and Uruguay, Harold (1869a) and Gillet (1911) cite only Brazil in the distribution range of C. moestrum . Bruch (1911) and Martínez (1959) tentatively cited the occurrence in Argentina, information that was replicated without questioning by Blackwelder (1944) and later confirmed by Martínez & Halffter (1986a) and Martínez (1989). Vazde-Mello (2000) confirmed the occurrence in Brazil. It seems clear, therefore, that this species is limited to a region within southeastern South America and is not present in Colombia as cited as a possibility in Harold (1867a)].
