Ceriagrion obfuscans Dijkstra, Mézière & Kipping, 2015
Darkening Citril

Type locality: Lower Lomami, Iloko stream on Lieki-Lileke path, DRC


Male belongs to the varians-group by (a) the blackish rhomboidal Pt with the anterior border shorter than the posterior; (b) the cerci that are wider than long and (almost) touch each other in dorsal view; and (c) the paraprocts without a heeled lower border in lateral view. However, unlike other group species, (1) the orange to red head, thorax and S1-2 blacken with age; (2) the humeral and metapleural sutures lack dark dots in the fossae, although this character is obscured with the darkening of the body; (3) the penis has a notably long, broad and squarish apex and lacks small horn-like cones on each side of its base; (4) S3-10 are always blackish, while at least S8-10 always remain red in other species; (5) the cerci are round rather than pointed in lateral view; and (6) the paraprocts are just over twice as long as the cerci, rather than under.
