Corynoneura Winertz, 1846 (Figs 32–34)

Head capsule very small (thus easy to overlook), narrow and yellow, often sculpturing on surface. Occipital margin pale to black. Antennae 4 segmented, subequal or longer than head, second and third segments are frequently darkened. Premandible with up to 12 minute teeth. Apical mandibular tooth smaller than any of 4 inner teeth. Mentum with 2–3 median teeth and 5 pairs of lateral teeth. Ventromental plates narrow.

Remarks: The unique feature of the genus is the extremely long 4 segmented antenna (often broken off in the subfossil material). Thienemanniella has similar shape of mentum but the 5-segmented antenna is shorter than head, third segment is shorter than second (while longer than second in Corynoneura); moreover, the head capsule is often pigmented (while usually pale in Corynoneura) without reticulation.

Two species, Corynoneura scutellata Winnertz, 1846 and C. lobata Edwards, 1924 were confirmed from the Tatra Mts. lakes (Bitušík 2004).

Corynoneura remains were found in lakes covering a broad altitudinal range, missing only in the uppermost Tatra Mts. lakes (Hamerlík et al. 2017). Three morphotypes were distinguished following Brooks et al. (2007).
