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.
