Description of Pudica wandiquei n. sp. (Heligmonellidae: Pudicinae), a nematode found infecting Proechimys simonsi (Rodentia: Echimyidae) in the Brazilian Amazon

“…The pattern of the bursa observed in the new species resembles that found in Pudica cattani Digiani et al 2017, P. evandroi (Travassos, 1937, and Pudica cercomysi (Durette-Desset and Tchéprakoff, 1969), but in general according to the classification key of Serrano et al (2019) Pudica wandiquei n. sp. can be distinguished from these three species by the distance between the ends of rays 6 and 8, which are close in P. cattani, P. evandroi, and P. cercomysi and separate in Pudica wandiquei n. sp.…”

“…Up to now, 15 Pudica species have been described, of which, seven are parasites of rodents of the family Echimyidae, Four of these species (P. minima, P. evandroi, P. tenua, and P. ginsburgi) were found parasitizing three different echimyid rodents of the genus Proechimys (P. roberti, P. semispinosus and P. longicaudatus) in the Amazon biome (Serrano et al, 2019). However, it is not yet known what the evolutionary relationship between the helminths parasites and these rodents.…”
