Parasite Journal De La Societe Francaise De Parasitologie
In this paper we provide a description of Topironemo coronatum n. gen n. sp. (Trichostrongyloidea, Obeliscoidinae) from the cricetid Holochilus brasiliensis or <<water rat>> in Argentina (Type material) and from Tapirus terrestris in French Guyana (voucher material in poor condition). The new genus is characterized by a corona radiata, on oesophageal tooth, a bilaterally synlophe with about 73 (male), 122 (female) cuticular ridges, a caudal bursa Pattern 2-1-2 with rays 5 and 6 parallel and close together and rays 5 longer than rays 3. The mosi closely related genus is the monospecific Teporingonema Harris, 1985, from a Mexican lagomorph, Romerolagus. The cephalic extremity oi this parasite is redescribed after the type-material. The systematic position of Teporingonema amongst the Obeliscoidinae is defined and the hypotheses concerning the origin of this sub family are provided.
