Nematode parasites of Puerto Rican tree frogs, Eleutherodactylus spp: two new species and a proposal of Poekilostrongylus gen. nov. (Trichostrongylidae).

Poekilostrongylus puertoricensis gen.nov., sp.nov. is proposed for nematodes recovered from Eleutherodactylus coqui, in Puerto Rico. The new genus is similar to Oswaldocruzia Travassos, 1917, but lacks longitudinal ridges on the cuticle. Oswaldocruzia lenteixierai Viqueras, 1938, is partially redescribed, and a key to the genera of the Oswaldocruziinae is given. Thelandros (Parathelandros) garciai sp.nov. is described from E. antillensis and E. portoricensis. Strongyloides sp. was found in E. antillensis and Aplectana spp. (females) were recovered from E. locustus, E. richmondi and E. coqui.
