Ceriagrion rubellocerinum Fraser, 1947
Red-tipped Citril

Type locality: Reserved forest, Le Banco, near Abidjan, Cote d'Ivoire

Diagnosis

Male is similar to C. annulatum by (a) head may blacken with age, at least S3-6 usually largely black with maturity, but at least S8-10 remain red; (b) humeral and metapleural sutures with dark dots in fossae (may disappear with darkening of body); (c) Pt rhomboidal, anterior border shorter than posterior; (d) penis with small horn-like cone on each side of base of apex; (e) apex of S10 with thick black denticles, these often merged to form thick black ridge or cluster; (f) cerci broad, wider than long, often overlapping each other (dorsal view); (g) paraprocts without heel (lateral view). However, differs by (1) labrum green to blue, thorax becoming blackish and pruinose with age; (2) eyes dorsally dark reddish rather than all green in life; (3) Pt blackish rather than red; (4) apex of S10 with deep circular excision, fortified with thick rim of black denticles (dorsal view); (5) black tooth placed near internal corner of cerci (dorsal view).
