Trithemis tropicana Fraser, 1953
Eastern Mantled Dropwing

Synonyms:

  • scientific: T. africana (Brauer, 1890) ssp. tropicana
  • vernacular: Eastern Phantom D.

Type locality: Eala, DRC

Diagnosis

Male is similar to many Trithemis species with (a) hamule with long sickle-shaped hook; (b) genital lobe directed away from hamule; (c) Abd largely black, often with some pale markings, appears blue pruinose or black with maturity. However, set apart from the rest by (1) ranging from DRC to Nigeria; (2) 16½-19½ Ax in Fw; (3) 6-9 cell-rows between anal loop and tornus; (4) Hw base broadly brown (rather than with small brown patch), including triangle. Replaced by T. africana in western Africa (see for separation). [Adapted from Dijkstra & Clausnitzer 2014]

Habitat description

Streams in open areas in forest. Often with coarse detritus and a sandy and/or soft (like muddy) bottom, and probably especially calmer sections (like pools) with emergent vegetation and/or submerged roots. From 0 to 700 m above sea level, but possibly higher up.

Distribution

confirmed: Cameroon; Congo-Brazzaville; Democratic Republic of the Congo; Gabon; Nigeria
