Abstract
A new species of nematode, Pterygodermatites (Paucipectines) sinopiensis
n. sp. is described based on specimens recovered from the intestine of the
white-bellied woolly mice opossum, Marmosa constantiae, trapped in the
municipality of Sinop, Mato Grosso state, Brazil. The genus Pterygodermatites
has 21 species described in mammals worldwide, and to date, only two
species have been described for marsupials in Brazil. The new species is
characterized by the presence of 23 small denticles and by the presence of
38–40 and 65 pairs of the cuticular processes in male and female species,
respectively. Additionally, male species possess three ventral precloacal fans,
and in female species, the cuticular processes are divided into 41 pairs of
comb-like and 24 pairs of spine-like processes; the vulva opens approximately
in pair 41. This study describes the parasite species fifth of marsupials in the
Neotropical region.
