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)].
