Description

Gymnometriocnemus Edwards / Bryophaenocladius Thienemann (Fig. 47)

Head capsule yellow to light brown, occipital margin pale or darkened.Antenna with 5 segments of variable lengths. Premandible with 3 teeth. Apical mandibular tooth shorter than combined width of 3 inner teeth. Mentum dark brown with paired, relatively broad and rounded median teeth and 4 pairs of lateral teeth gradually decreasing in size. Ventromental plates distinct, sclerotized, not extending beyond outer lateral tooth, reminding ears and visible at the first sight (Fig. 47).

Remarks: Without body and antennae, larval Gymnometriocnemus virtually cannot be distinguished from Bryophaenocladius.

Bryophaenocladius muscicola (Kieffer, 1906) and B. cf. subvernalis (Edwards, 1929) are known from the Tatra Mts. lakes (Bitušík 2004).

Subfossils were recorded in low abundance but relatively frequently in the studied lakes.
