Genus Synonchiella Cobb, 1933

Type species

Synonchiella truncata Cobb, 1933

Diagnosis

Cuticle without lateral differentiation. Outer labial setae and cephalic setae usually in one circle. Buccal cavity with three equal mandibles made of two branches fused posteriorly; the two branches completely fused in some species (e.g., S. rotundicauda sp. nov.). Pharynx without posterior or anterior bulb. Cupshaped pre-cloacal supplements present.

Remarks

Synonchiella denticulata Cobb, 1933 , S. ferox Cobb, 1933 and S. siphonolaimoides (Allgén, 1940) were considered doubtful by Gerlach (1964) due to incomplete descriptions. The latter author also transferred S. annulata Gerlach, 1952 and S. orcina Gerlach, 1952 to the genus Latronema .
