Umma saphirina Förster, 1916
Sapphire Sparklewing
Type locality: Entebbe, Uganda
Diagnosis
Male of this species and U. mesostigma (of which it is probably a synonym) is similar to U. longistigma by (a) anterior face of basal segment of antenna at least partly dark; (b) Pt well-developed, large and somewhat swollen, 1.5-3 mm, acutely angled due to oblique proximal border, brown to black and at most slightly metallic; (c) cells between Pt and R2 at most as deep as long; (d) venation less dense, e.g. Fw quadrilateral with 5-8 cross-veins; (e) legs and poststernum glossy dark brown to black. However, both differ by (1) mandibular bases (between genae and labrum) largely dark rather than pale; (2) poststernum (venter of thorax) with dense patch of long dark hairs, rather than short whitish hairs; (3) cerci with clump of thick bristles near tip (clearly visible in lateral view); (4) paraprocts short and broad, about 2/3 as long as cerci.

Habitat description
Mostly headwaters, but also larger streams, shaded by forest. Mostly with a gravelly bottom, but often also a sandy and/or probably soft (like muddy) bottom, and probably submerged roots and/or coarse detritus. From 200 to 1800 m above sea level, but possibly up to 2400.
