Trithemis brydeni Pinhey, 1970
Percher-like Dropwing

Type locality: Msamfu, Kasama, Zambia

Diagnosis

Male is similar to T. hecate by (a) dorsum of frons metallic blue or purple, occasionally pale, bronze or black; (b) labrum often largely black; (c) venation largely dark, brown to black, like veins of Pt; (d) all wings with 2-8 celldoublings in radial planate [0-8]; (e) Fw discoidal field of 3-4 rows; 3-9 rows between anal loop and tornus; (f) arculus between Ax1-2, at most at Ax2 in Hw; (g) Hw base clear, yellow or brown, colour is usually brown if it extends beyond Cux; (h) hamule with short, strongly curved hook; genital lobe curved forward, stands parallel to hamule; (i) Abd largely black, often with some pale markings, appears blue pruinose or black with maturity. However, differs by (1) ranging from N Botswana to NE Zambia; (2) pruinosity of thorax in life black; (3) anterior lamina with flat anterior profile and pair of knobs on apex; genital lobe much shorter than long-hooked hamule.
