Townes, 1945
Body
Medium sized larvae up to 8 mm long. Few claws on the very elongated posterior parapods Chern macroc anal segments. Apparently 20 body segments present. No lateral and ventral tubules. Procercus short and anal tubules elongated (Chernovskij, 1961; Wiederholm, 1983).
Head
Antenna
The antenna is almost as long as the head with 8 segments Chern macroc antenna. The blade is much shorter than the flagellum. Lauterborn organs are absent.
Mentum
The mentum is concave with a broad median tooth and four pairs of lateral teeth Chern orb ment.
Labrum
SI is simpel and labral lamellae are absent. The pecten epipharyngis consists of a single scale. The premandible has three apical teeth (Wiederholm, 1983).
Mandible
The mandible with an apical tooth and no inner teeth. The pecten mandibularis and seta interna are absent (Wiederholm, 1983).
Differential characteristics
Chernovskiia is the only genus with 8 antennal segments Chern macroc antenna.
C. orbicus differs from C. macrocera by the shape of the mentum Chern orb ment.
