A female of Eudorylaimus sp. with two vulvae.

Abstract

A female of Eudorylaimus sp. with two vulvae. Nematropica 31:109-111. A female of Eudorylaimus sp. with two vulvae was found in Tempisque Conservation Area in Costa Rica. Thousands of nematodes have been prepared in Cobb[sub2]s slides to study nematode diversity in Costa Rica; nevertheless, only one aberrant female has been found. The two vulvae are very close to each other and vaginal sclerotization plates show abnormal formation. There is no linkage between the uterus and the gonoducts and the ovaries are poorly developed. An absence of sperm and eggs suggests that the genital apparatus is not functional. Because identification at the species level was not achieved, more specimens and studies are needed.
