Paragomphus cammaertsi Dijkstra & Papazian, 2015
Type locality: Agumatsa River, Wli, Ghana
Male recalls P. cognatus and the potentially sympatric P. serrulatus by (a) the moderate size, Hw 22.5-23.5 mm (n = 3) and rather intermediate extent of dark markings, with the (b) pale occiput and narrowly black-edged and -based labrum contrasting with the largely dark vertex, antefrons and postclypeus; (c) antehumeral and metepisternal stripes almost as prominent as the other pale thoracic markings; and (d) S3-6 laterally pale over much of their length; as well as (e) apices of the cerci that diverge in dorsal view. However, (1) the pale antehumeral and metepistermal markings consist of a stripe and a separate dorsal spot, while typically in P. serrulatus they form complete stripes and in P. cognatus they are broken up into three spots; (2) the black S8-10 and appendages are marked laterally with some reddish brown, rather than being contrastingly marked with yellow at least on the appendages; (3) the appendages are short, the cerci being less than twice as long as S10 and the epiproct about half as long S10, rather than at least twice and just as long respectively, thus being intermediate between P. nyasicus and P. crenigomphoides; and (4) the curved section of the cerci is notably short and sharply bent in lateral view, with thick and rounded tips with 6-7 rather indistinct teeth, rather than square-ended with quite distinct and well-spaced teeth.

Not known well, but mostly streams shaded by forest. Probably often with a gravelly and/or sandy bottom. From 200 to 1200 m above sea level.
