Pterygodermatites parasitizes the digestive tract of different mammals worldwide. In the Neotropical region, thirteen species of this genus, belonging to three subgenera, are reported in carnivores, marsupials, rodents, armadillos and bats. During an investigation on bats helminthfauna in São Paulo State, specimens of a new species, Pterygodermatites (Paucipectines) andyra n. sp., were observed in the small intestine of 28 bats. The present study describes this nematode. For that, we necropsied 340 bats, captured in urban environment by Municipal Disease Control Services. From these, 122 specimens, which 24 males and 98 females, were recovered of 17 Eumops glaucinus, six Eumops auripendulus, four Eumops perotis, and one Promops nasutus. This species is characterized by the presence of subterminal oral opening, with prominent denticles and buccal capsule with three oesophageal teeth of jagged edges. Robust male, with 2.35±0.65 long and 0.14±0.03 wide and 40 to 43 pairs of subventral cuticular spines. Their tail is coiled, bearing thin caudal alae, 10 pairs of papillae, and one pre-cloacal and semicircular fan on the ventral surface. The spicules are equal and the cone-shaped gubernacule is poorly sclerotized. Robust female, thinner in the anterior portion, with 9.05±1.61 long and 0.15±0.01 wide and 67 to 80 cuticular spines. This species differs from Neotropical species of the subgenera Pterygodermatites and Multipectines due to the subterminal oral opening and inferior number of cuticular spines in both sexes. Regarding the species of the subgenus Paucipectines, it differs by show equal spicules, one semicircular fan, superior number of prevulvar spines, and from Pterygodermatites (Paucipectines) kozeki, species that more resembles, by show the spines in asymmetrical position and disparate number, after of the vulvar region, and first pair of pre-cloacal papillae composed of two short pedunculated papillae, thin caudal alae and gubernacule. This is the third species of Pterygodermatites described in Neotropical bats.
