Abstract

A new species of nematode parasite of the subfamily Pudicinae (Heligmosomoidea: Heligmonellidae) is described from the small intestine of Proechimys simonsi (Rodentia: Echimyidae) from the locality of Nova Cintra in the municpality of Rodrigues Alves, Acre state, Brazil. The genus Pudica includes 15 species parasites of Neotropical rodents of the families Caviidae, Ctenomyidae, Dasyproctidae, Echimyidae, Erethizontidae, and Myocastoridae. Four species of this nematode were found parasitizing three different species rodents of the genus Proechimys in the Amazon biome. Pudica wandiquei n. sp. can be differentiated from all other Pudica species by the distance between the ends of rays 6 and 8 and the 1-3-1 pattern of the caudal bursa in both lobes.

Highlights

The parasitic nematodes of the genus Pudica Travassos and Darriba, 1929 are members of the subfamily Pudicinae Skrjabin and Schikhobalova, 1952, family Heligmonellidae Skrjabin and Schikhobalova, 1952
The present study describes a new species of the genus Pudica found infecting the small intestine of Proechimys simonsi Thomas, 1900 at the locality of Nova Cintra, in the municipality of Rodrigues Alves, Acre state, Brazil
The specimens were collected in the municipality of Rodrigues Alves, Acre state, Brazil (7.8149S, 72.6799W), using a Tomahawk® Live Trap (USA) baited with a mixture of peanut butter, banana, oats, and bacon

Summary

Introduction

The parasitic nematodes of the genus Pudica Travassos and Darriba, 1929 are members of the subfamily Pudicinae Skrjabin and Schikhobalova, 1952, family Heligmonellidae Skrjabin and Schikhobalova, 1952. A total of 22 Proechimys species have been described from localities in Central and South America (Patton and Leite, 2015), and four Pudica species have been found parasitizing three of these species – Proechimys longicaudatus (Rengger, 1830), Proechimys semispinosus (Tomes, 1860), and Proechimys roberti Thomas, 1901 – in the Amazon biome (Cordeiro et al, 2015b).
