Winnertz, 1846
Body
Small larvae up to 5 mm long. Living larvae greenish or with rusty stains. The body is very slender. The 2nd and 3d thoracic segments are fused leaving only two thoracic segments. The anterior and posterior parapods are unusually long and both with crowns of claws. The posterior parapod bears a spine on the ventral side Coryno antenn thorn post pp. Two pairs of anal tubules present (Wiederholm, 1983; Moller Pillot, 1984b).
Head
The head length is 0.3 - 0.4 mm and very narrow.
Antenna
The antenna is as long or longer than the head, with 4 segments. The second and third segments sometimes are brown Coryno antenna.
Mentum
The mentum has (rarely) two or three median teeth and 5 pairs of lateral teeth Coryno scutell agg mentum. Sometimes the first lateral tooth is smaller than the second Coryno lobata mentum.
Labrum
The pecten epipharyngis consists of three spines. SI is simpel and the premandible has up to 12 tiny teeth (Wiederholm, 1983).
Mandible
The mandible with a distal tooth and 4 inner teeth. The seta interna present or absent (Wiederholm, 1983).
Differential characteristics
The slender head with the unusually long antenna are distinctive Coryno antenna. Only Thienemanniella has a head of similar shape, but the antenna is only half the head length Antenna half headlength. Heterotanytarsus also has antennae as long as the head but the headcapsule is much wider.
