Paragomphus dispar Dijkstra, Mézière & Papazian, 2015
Type locality: Moyabi, Gabon
Male is nearest to the poorly known P. maynei by its (a) great size, Hw 27.0-33.0 mm (n = 7); (b) largely black face and occiput; (c) entirely green S2 that contrasts with the mostly dark abdomen; (d) abrupt dorsal hump on S10; (e) slender and tapering cerci that terminate in a saw-like ridge of about six equal teeth; and (f) epiproct that is almost half as long as the cerci. However, (1) the black labrum is darkest on the border, enclosing a greenish bar, rather than being quite uniformly brown and even a fraction paler on the border; (2) the mesepisterna are entirely yellow-green except for a thick black border along the humeral suture and a thin black line on the posterior half of the middorsal carina, rather than all dark with only small isolated postdorsal stripes; (3) the sides of the thorax are black with complete broad greenish stripes on the mesepimeron and metepimeron, rather than wholly dark; (4) S3-10 are black with only a pair of green spots on the basal fifth of S3 and brown sides to S8-10, rather than largely pale on the sides of S3 and S7, and extensively rusty on S8-10; and (5) the cerci are more smoothly curved. The large size, dark face and bright thoracic front recall P. aureatus, but that has a pale metepisternal stripe that is of similar length and width as the mesepimeral and metepimeral stripes, pale markings on S4-5 and S7, a flat-topped S10, rather straight and thick cerci with abruptly down-curved tips, and an epiproct that is well over half as long as the cerci.
