Antenna 6-segmented, large Lauterborn organs alternate on segments 2 and 3. Premandible with 3 distinct apical teeth and 1 blunt inner tooth. Mentum pale brown in colour; dorsal tooth very strong, apical tooth only slightly larger than 2 inner teeth. Mentum weakly pigmented with two rounded median teeth and 6 pairs of lateral teeth; first lateral tooth very short. Ventromental plates distinctly triangular in shape ( Fig. 85 ). Remarks: Lauterborniella may be confused with Zavreliella and perhaps with Polypedilum nubeculosum - type . The first and the second lateral teeth of mentum are distinctly separate in Lauterborniella , while partially fused in Zavreliella . Shape of setae submenti (if preserved in subfossils) is also indicative: it is branched in Lauterborniella , while simple in Zavreliella . Ventromental plates in Lauterborniella are triangular, while fan-shaped in Polypedilum nubeculosum - type ( Fig. 89 ). Subfossil remains were found in one dystrophic lake situated in forest zone, while data on occurrence of living immature stages in the Tatra Mts. lakes does not exist, yet. Only one species, L. agrayloides (Kieffer, 1911) is known from the Holarctic.
