Genus Crestanema Pastor de Ward, 1985 View in CoL
The monospecific genus Crestanema was described by Pastor de Ward (1985) from Argentina. Crestanema is closely related to Nygmatonchus and Trochamus but differs from the former by the absence of pre-cloacal modifications and from the latter in having a gubernaculum with telamon or lateral guiding piece.
Diagnosis (modified from Pastor de Ward 1985): Cuticle formed by rings with internal anterior and posterior processes, with alternate hooking. Wing type lateral differentiation nerve ring level onward. Six outer labial and four cephalic setae arranged in one circle. Amphideal fovea transversally oval, with slightly concave posterior margin. Buccal armature formed by one dorsal and two small ventrosublateral teeth. Spicules simple in structure. Gubernaculum with two central pieces and two lateral guiding pieces.
Number of valid species: 1.
