Ventral part of mentum laterally developed into ventromental plates of different shape, usually striate and never with beard ........ ...................................................................................................... Chironominae 2. — Ventromental plates, if developed, never striated and sometimes with beard beneath ........................................ 3 3. Procerci obvious, minimum 3 × as long as wide, usually much longer (8 – 10 ×). Premandibles absent (Figs. 7 – 9) ......... Podonominae 3. — Procerci less than 3 × as long as wide, usually much less or reduced. Premandibles present .................................... 4 4. Prementum with 3 dense brushes of hair-like processes. Usually with distinctive ‘ collar’ (occipital margin of the head). Mentum either very wide, with 2 narrow medium teeth and> 8 lateral teeth of similar size (Figs. 5 – 6), or with 1 very broad median tooth and 5 laterals (Fig. 4). Head dark brown, body ‘ fleshy’ ........................................................... Diamesinae (Heptagyiini) 4. — Prementum with lamellae rather than brushes. Mentum usually narrower, with at most 3 median teeth. Body of various coloration ......................................................................................................... Orthocladiinae Notes: The only Tanypodinae recorded in the studied streams was Pentaneura sp. (Fig. 23).
