Micromacromia camerunica Karsch, 1890
Stream Micmac

Type locality: Cameroon, no locality data available.

Diagnosis

Male is similar to M. camerunica by (a) labium all pale; (b) antehumeral stripe broad and complete, at most small black marking above metastigma; (c) Fw triangle and subtriangle of 1 cell, sometimes 2; (d) anal loop of 2-9 cells, rarely up to 12. However, differs by (1) Fw discoidal field of 2 cell-rows at base, rather than 1; (2) Fw with 1 or rarely 2 Cux, rather than 3-5; (3) Hw triangle of 2 cells, rather than usually 1; (4) anal loop distinct and of 6-12 cells, rather than indistinct and of 2-4; (5) hind femur with 20-30 rather than 10-20 denticles in external-anterior row; (6) posterior corner of hamule blunt, rather than angled.

Habitat description

Mostly streams, but also rivers, mostly shaded by forest, but also in open areas in forest or possibly in gallery forest. Often with coarse detritus and a gravelly bottom, sandy and/or soft (like muddy) bottom, and probably submerged roots. From 0 to 1700 m above sea level, but mostly below 900.
