Metriocnemus ( Metriocnemus ) fuscipes (Meigen) Figs 24A–F Diagnosis. Body segments with dark purple bands, (Fig. 24A) Labrum (in part, Fig. 24B) SI seta simple, peg-like; labral lamella reduced to conical plate; antenna (in part, Fig. 24B) strongly reduced, 4-segmented, 1 st segment 1.5x wider than long, flagellum with 3 minute segments, AR 1.0, blade longer than flagellum; mandible (Fig. 24C) with 4 inner teeth; mentum (Fig. 24D) with tiny pair of median teeth deeply recessed between the inwardly pointed 1 st laterals, base with small lobe and long posterior sclerotized extension; VM plate indistinct, appearing raised high above lateral teeth; anterior parapods fused with two groups of apical claws and surrounded by numerous rows of spinulae (Fig. 24E); posterior end of abdomen as in Fig. 24F; procercus with relatively short apical setae, about 2.5x as long as procercus; anal tubules cylindrical, about as long as posterior parapods. Notes. The mentum is strongly arched dorsoventrally, and the VM plates raised high making it appear to be inline with the 2 nd laterals. Ecology and habitat. A circumpolar species, larvae live in damp soil adjacent to springs, spring runs, small streams and also within streams (Oliver & Dillon 1997). Sampling sites. Arrowhead and Algonquin Provincial Parks. Nearctic distribution. First published record for Canada: Ontario.
