Abstract

A new species of oxyurid, Skrjabinodon spinosulus, is described, on the basis of samples recovered from Mabuya dorsivittala Cope, 1862 in Brazil. Skrjabinodon spinosulus sp. n. is included in the group in which the males are provided with a spicule. The new species proposed herein, differs from those of the group, by the large number of spines (70-80) on the tail of the females when compared to those (3-48) in the other species. The number of spines is a character of great taxonomic importance in the specific diagnosis of these nematodes. This is the second report of the genus Skrjabinodon Inglis, 1968 in South America.
