Micromacromia zygoptera (Ris, 1909)
Spring Micmac

Synonyms:

  • scientific: Eothemis zygoptera; Neodythemis scalarum Pinhey, 1964
  • vernacular: Small M.

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 1 row at base, rather than 2; (2) Fw with 3-5 Cux, rather than 1 or rarely 2; (3) Hw triangle usually of 1 cell (sometimes 2) rather than invariably 2; (4) anal loop indistinct and of 2-4 cells, rather than distinct and of 6-12; (5) hind femur with 10-20 rather than 20-30 denticles in external-anterior row; (6) posterior corner of hamule angled, rather than blunt.

Habitat description

Mostly headwater streams, but probably also seeps and springs, shaded by forest. Often with coarse detritus and a sandy and/or soft (like muddy) bottom, and probably submerged roots. From 0 to 800 m above sea level.

confirmed: Côte d'Ivoire; Cameroon; Gabon; Ghana; Liberia; Nigeria; Republic of Guinea; Sierra Leone; NOT confirmed: Benin; Togo
