Trithemis integra Dijkstra, 2007
Albertine Dropwing

Synonyms:

  • scientific: T. basitincta sensu Pinhey, 1970 nec Ris, 1912

Type locality: Mpanda District, Tanzania

Diagnosis

Male is similar to T. aconita and T. congolica by (a) dorsum of frons metallic blue or purple, occasionally pale, bronze or black; (b) all wings with 2-8 celldoublings in radial planate [0-8]; (c) Fw discoidal field of 3-4 rows; 3-4 rows between anal loop and tornus; (d) arculus between Ax1-2, at most at Ax2 in Hw; (e) Hw base at most with small brown patch, excluding triangle; (f) anterior lamina not bifid, apex at most grooved; (g) hamule with long sickle-shaped hook; genital lobe directed away from hamule. However, differs by (1) being restricted to Uganda, W Tanzania and E DRC; (2) 16½-18½ Ax in Fw [14½-18½]; (3) patch at Hw base confined to subcostal and cubital space, not or scarcely extending onto anal field, resulting in distinct double streaks; (4) apex of anterior lamina dark rather than pale, rather pointed rather than swollen, and bearing long hairs; (5) hamule gradually curved rarther than straight; (6) genital lobe short and pointed, rather than long and rounded.
