[Dipetalonema (Alafilaria) hydrochoerus Yates (1983)].

Four filariae are known to parasitize the capybara "Hydrochoerus hydrochaeris" namely the "Cruorifilaria tuberocauda", Eberhard, Morales & Orihel, 1976; the "Dipetalonema (Alafilaria) hydrochoerus", Yates & Jorgenson, 1983, and "Mansonella longicapita" and "Mansonella rotundicapita [corrected]", Eberhard, Campo-Aasen & Orihel, 1983. In this study we describe briefly the adult parasites and, the microfilaria of the species "Dipetalonema (Alafilaria) hydrochoerus" which were isolated from skin nips and we have found that the capybara "Hydrochoerus hydrochaeris" is parasitized in a proportion of 80% in the 16 animals studied.
