Umma cincta (Hagen in Selys, 1853)
Broad-winged Sparklewing
Type locality: Vane, Ghana
Diagnosis
The only Umma species west of Nigeria but in central Africa overlaps with several species that are similar by (a) head, entire thorax and Abd green to blue metallic; (b) anterior face of basal segment of antenna at least partly dark; (c) Pt present and brown to black and at most slightly metallic; (d) legs and poststernum glossy dark brown to black. However, differs by (1) venation very dense, e.g. Fw quadrilateral with 9-12 cross-veins; (2) Pt poorly developed or tiny, 1 mm, rather rectangular due to straight proximal border; (3) cells between Pt and R2 distinctly deeper than long, sometimes split in two.
