SEM study of a topotype population of Paracrobeles psammophilus Navarro & Lluch, 1999 (Rhabditida: Cephalobidae) and its taxonomic implications

in Nematology

Summary

Paracrobeles psammophilus from the type locality is redescribed based on SEM studies. In addition, material of P. psammophilus previously described from Sicily (Italy) is revised. Species of Paracrobeles are analysed and form two morphological groups: the laterellus-group with three species (P. kelsodunensis, P. laterellus and P. mojavicus) having a lip region with two guard processes at both primary and secondary axils and shorter and more robust spicules, and the psammophilus-group with two species (P. deserticola and P. psammophilus) having primary axils bearing two guard processes and secondary axils with only one guard process and longer and slender spicules. Another four species (Acrobelinema cornis, Cervidellus cancellatus, C. rarus and C. sonorensis), having an intermediate morphology between Paracrobeles and Nothacrobeles, are transferred to Nothacrobeles (= Acrobelinema n. syn.).
