Cuticle with homogeneous punctation pattern along the body, with lateral differentiation of larger dots. Transverse slit-like amphideal fovea. Buccal cavity usually with three solid teeth, the dorsal tooth larger than ventrosublateral teeth. Occasionally, only one dorsal tooth is observed. Ocelli may be present. Pharynx with terminal bulb, simple or double. Males usually with cup-shaped precloacal supplements. The genus is very similar to Atrochromadora , the main difference is the amphideal fovea shape which is more circular in the current genus; the variable number of teeth (one or three) is also another feature that can be easily used in the identification of Chromadora species.
