Syst Parasitol. 2015 Nov;92(3):251-9. doi: 10.1007/s11230-015-9600-1. Epub 2015 Oct 7.


Kentropyxia hylae n. sp. is described based on material from small intestine of Osteocephalus taurinus Steindachner from Caxiuanã National Forest, municipality of Melgaço, state of Pará, Brazil. The new species is easily distinguished from the type-species and only species of the genus, Kentropyxia sauria Baker, 1982, by its smaller dimensions, the presence of cervical alae, spicules divided into three parts: a robust, single pointed outer processes ending with small finger-like projections and latero-dorsal and latero-ventral processes branching at final portion of spicule into six main branches, each ending with 14 projections in the latero-dorsal process and 15 projections in the latero-ventral process and by the presence of a middle groove in bursa ray 4. This is the second species parasitic in hylids from the Brazilian Amazon and a new parasite for O. taurinus.
