Chaetocladius piger - type ( Fig. 31 )

Mentum with paired median teeth, and 5 pairs of lateral teeth, outermost lateral is minute. Ventromental plates are broad and bulbous ( Fig. 31A ).

Remarks: Head capsules were found in eleven lakes without obvious respect to altitude, however, recent larvae of the genus were typical for lakes and ponds of higher elevations with significant fluctuation of water level ( Hamerlík et al. 2017).
