Stegelletina laticollaris n. sp., a second new species of the genus from Senegal (Nematoda: Cephalobidae).

Stegelletina laticollaris n.sp. from marginal soil at Camberene, Senegal was studied with light microscope and SEM. It is small (L = 0.3 mm) and differs from known species of the genus in the expanded pharyngeal collar, in the cephalic probolae with six or seven digitate tines, and in the shape of the labial probolae, which carry a basal ridge and are bifurcate at two levels, with two platelets implanted at the primary bifurcation. The presence of the basal ridge is reminescent of the genus Nothacrobeles.
