Umma electa Longfield, 1933
Metallic Sparklewing

Synonyms:

  • scientific: U. distincta Longfield, 1933

Type locality: Kambove, Katanga, DRC

Diagnosis

Similar to other Umma species by (a) labium all black in stead of pale; (b) humeral and interpleural sutures enclosed in metallic areas, at most with pale traces; (c) wings clear; (d) Fw discoidal field 1 row only well proximal to node, 15-25 cells wide on wing border; (e) base of anal vein directed towards wing base. However, differs by (1) occuring from Angola and N Zambia to Katanga; (2) anterior face of basal segment of antenna all pale; (3) legs, Pt and poststernum (when not pruinose) metallic green, blue or violet.
