Description:

Helminthological examination of two rare, endemic species of plethodontid salamanders, the Texas blind salamander (Typhlomolge rathbuni Stejneger) and the San Marcos dwarf salamander (Eurycea nana Bishop), from the subterranean waters and springs in San Marcos, Hays County, central Texas, USA revealed the presence of three new, previously undescribed species of intestinal helminths: Brachycoelium longleyi sp. n. (Trematoda) from T. rathbuni (type host) and E. nana, Dendronucleala americana sp. n. (Acanthocephala) from T. rathbuni, and Amphibiocapillaria texensis sp. n. (Nematoda) from T. rathbuni', nematode larvae probably belonging to the last named species were recorded from E. nana. Brachycoelium longleyi can be distinguished from all congeners primarily by its conspicuously small eggs among other features, whereas A. texensis differs from its closest congeneric species A. tritonispunctati mainly in the structure of mature eggs and a markedly shorter spicule. Dendronucleala americana is the first species of the family Dendronucleatidae from the New World, differing from its Asian congeners mainly in the number and arrangement of proboscis hooks, number of giant hypodermic nuclei and in the position of testes.
