Pseudagrion (A) emarginatum Karsch, 1893
Blue-faced Sprite

Synonyms:

• scientific: P. coeruleiceps Longfield, 1959

Type locality: Bukuru, Nigeria

Diagnosis

Male is similar to P. hageni by (a) seldom pruinose, at most (partly) on thorax and Abd base; (b) entire dorsum of S7 black, rarely with small apical marking (in which case antehumeral stripe often half as wide as mesepisternum); (c) cerci with lower branch not bent inwards but in line with upper branch; lower branch bearing flange that ends with 1 tooth near base. However, differs by (1) ranging from NE DRC to W Africa; (2) postclypeus blue with black base, rather than all black; (3) branches of cerci very short (lateral view).
