Pseudagrion (B) aureolum Dijkstra, Mézière & Kipping, 2015
Nugget Sprite

Type locality: Batéké Plateau, Laboumi River, Gabon

Diagnosis

Male is unlike any Pseudagrion of the B-group by the combination of (1) the small size, Hw 15.5-17.5 mm (n = 13); (2) the orange-yellow face and front of eyes; (3) the deep rufous back of the eyes, postocular spots and thorax, all almost devoid of black markings; and the male structures that are close to but distinct from those of its (genetically) nearest relatives, especially P. glaucescens: (4) the penis is simple and square-ended; (5) the cerci are somewhat longer than the simple paraprocts and have a distinctive though small subapical tooth on the lower flange, which creates a three-pointed tip in dorsal view.
