Subfamily Euchromadorinae

Diagnosis (modified from Tchesunov, 2014): Cuticle with complex heterogenous ornamentation (except in Endeolophos with homogenous ornamentation). The six outer labial and four cephalic setiform sensilla may be arranged in a single circle (6+10) or two separate circles (6+6+4). Amphideal fovea transverse slit-like or oval (elliptical). Buccal cavity with large or small dorsal tooth, with or without denticles or smaller ventrosublateral teeth. Pharynx with or without defined terminal bulb. Gubernaculum usually with hammer- or L-shaped lateral pieces (wrongly indicated as telamon in some descriptions). Precloacal supplements absent in males, but a precloacal differentiation of body cuticle may be present. All genera in this subfamily are marine, with no records so far in freshwater.
