Urothemis thomasi Longfield, 1932
- scientific: U. signata (Rambur, 1842) ssp. aethiopica Nielsen, 1957
Type locality: Qara Mountains, Saudi Arabia
Male is similar to U. assignata and U. luciana by red Abd, thorax and frons with maturity. However, differs by (1) Pt 2.5 mm or less; (2) Hw base usually with orange and not dark brown marking; (3) hamule about as long as genital lobe; (4) Abd dorsum without black. [Adapted from Dijkstra & Clausnitzer 2014]
Not known well, but probably often temporary streams and possibly rivers in open landscapes. Often calmer sections (like pools), usually with emergent vegetation. Inferred to occur at around 1600 m above sea level, but probably actually found much lower.
