Pseudagrion (A) rufocinctum Pinhey, 1956
Albertine Sprite

Synonyms:

  • scientific: P. risi Schmidt in Ris, 1936 ssp. rufocinctum

Type locality: Maramba river near the Victoria Falls, Uganda

Diagnosis

Species not particularly close to any one of the Pseudagrion A species, however similar by (a) mostly species of forested or shaded habitats; (b) seldom pruinose, at most (partly) on thorax and Abd base; (c) thorax extensively black, usually with distinct (sometimes pruinose) antehumeral stripes; (d) legs usually at least broadly marked with black. Tarsal claws with small hook or notch beside main hook; (e) lower and upper branches of cerci both extend somewhat, creating mouth-like gap between them; (f) paraprocts pointed and up-turned. However, species set apart by (1) being restricted to Uganda, W Tanzania and E DRC; (2) anterior border of postclypeus usually yellow or orange, rather than black or pale blue; (3) cerci with lower branch bent strongly inwards and with separate small tooth at base (dorsal view).
