Description

Genus Gammanema Cobb, 1920

Type species

Gammanema ferox Cobb, 1920 (junior synonym of Gammanema rapax (Ssaweljev, 1912)).

Diagnosis

Cuticle without lateral differentiation, four slender cephalic setae; outer labia either papillose or setose. Amphideal fovea usually spiral, rarely loop-shaped.Anterior buccal cavity large, cup-shaped, surrounded by rhabdions with pointed projections at their posterior ends; posterior buccal cavity smaller, often with broad column-shaped rhabdions. Pharynx without anterior or posterior bulb. Pre-cloacal supplements present, usually cup-shaped, rarely setose or tubular. Short conical tail.

Remarks

Gammanema paramenzeli (Allgén, 1935) was considered doubtful by Gerlach (1964), Trogolaimus uniformis Cobb, 1920 was transferred to Gammanema by Tchesunov & Okhlopkov (2006) and G. fennicum Gerlach, 1953 was re-established as a valid species by Okhlopkov (2002).

*approximate values only since no anus was observed in female specimens
