Antenna 6-segmented, Lauterborn organs alternate on segments 2 and 3. Premandible with 3 ( pedellus - type ) or 5 ( rydalensis - type ) teeth. Mandible with pale dorsal tooth, apical tooth and 3 inner teeth darkly pigmented. Median tooth of mentum trifid, pale or as dark as rest of mentum; central tooth either very small, so median tooth appears to consists of two teeth ( pedellus - type ), or about the same size as outer medians ( rydalensis - type ); 6 pairs of lateral teeth, while first and second laterals fused. Ventromental plates narrow and strongly curved and coarsely striated on upper half. Remarks: The mentum with 3, usually pale, median teeth and mandible with 3 inner teeth are distinctive. Superficially similar genera Omisus and Paratendipes have 4 median mental teeth. In comparison with Stictochironomus the first lateral tooth of mentum is not lower than second. Only Microtendipes chloris (Meigen, 1818) , belonging to the pedellus species group is known form the Tatra Mts. lakes. Subfossil remains belonging to one morphotype were found in the lakes situated at lower altitude in sub-alpine zone.
