Diplocladius Kieffer ( Figs 41, 42 )

Head capsule dark brown, occipital margin black. Antenna 5-segmented, premandible bifid. Mandible with 4 inner teeth, their combined width is larger than length of apical tooth. Mentum broad with two median teeth and 6 pairs of lateral teeth. The first lateral tooth is subequal to median tooth and second lateral tooth is smaller than first lateral and third lateral. Ventromental plates are long and broad with noticeably long and dense beard ( Fig. 42 ).

Remarks: The unique shape of mentum with long beard is distinctive for the genus.

Diplocladius cultriger Kieffer, 1908 , is the only species known in the Holarctic. It was found in one lake of our lake set.
