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. FIGURES 32–36. Corynoneura arctica- type: 32—head capsule (arrow indicates net-like reticulation). Corynoneura edwardsi type: 33—head capsule. Corynoneura lobata- type: 34—head capsule (arrow indicates wrinkled sculpturing). Cricotopus intersectus- type: 35—head capsule. Cricotopus ( Isocladius ) sylvestris -type: 36—head capsule. 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) .
