Diagnosis
Male is similar to U. luciana by (a) Abd, thorax and frons red with maturity; (b) Pt 3.5 mm or more; (c) Hw base usually with dark brown marking that enters triangle; (e) hamule longer than genital lobe; (f) at least dorsum S8-9 with black markings. However, differs by (1) smaller size, Hw 30-36 mm; (2) usually 7 Ax in Fw; (3) basal markings extend at most to Ax2 in Hw, not or hardly developed in Fw. [Adapted from Dijkstra & Clausnitzer 2014]
Habitat description
Standing waters, but possibly also lakes, rivers and flowing channels in marshes, in open landscapes, open areas in forest or shaded by gallery forest. Usually with emergent vegetation and often coarse detritus and a soft (like muddy) bottom. From 0 to 1700 m above sea level, but mostly at lower elevations.
