Parametriocnemus Goetghebuer View in CoL View at ENA / Paraphaenocladius Thienemann ( Fig. 58 View FIGURES 54–59 )
Head capsule yellow, occipital margin slightly darker. Antenna usually 5-segmeted, when 6-segmented, last segment vestigial. Premandible with 2–6 teeth. Mandible with 3 inner teeth, apical tooth short. Mentum with paired median teeth and five pairs of lateral teeth, fifth lateral minute. Ventromental plates distinct, extending beyond the last lateral tooth, with second plate inside main plate. Setae submenti are positioned high on mentum, about at the level of the outermost lateral teeth ( Fig. 58 View FIGURES 54–59 ).
Remarks: Subfossil larval head of Parametriocnemus essentially cannot be distinguished from Paraphaenocladius . If premandibles are present, specimens with two and more than three apical teeth can be allocated to Parametriocnemus as premandible of Paraphaenocladius consists of 3 apical teeth.
Limnophyes superficially resembles Parametriocnemus / Paraphaenocladius but it differs from it by having darkly pigmented lobe below outermost lateral tooth, subequal lateral teeth, and weakly developed ventromental plates ( Fig. 51 View FIGURES 49–53 ).
Only one species of the Parametriocnemus genus ( P. boreoalpinus Gouin, 1942 ) was recorded from the Tatra Mts. lakes ( Bitušík 2004).
Subfossil remains were found rarely.
