Notogomphus bosumbuli Dijkstra, 2015
Type locality: Lower Lomami, forest west of Djabir and Yaengo, DRC
Male recalls N. leroyi by its (a) largely black lower frons, clypeus and labrum, the latter with a pair of large basal pale spots; (b) black occiput; (c) broad and complete black interpleural and metapleural stripes on the thorax as well as well-defined pale postdorsal and antehumeral stripes separated from each other and the pale area of the middorsal carina (like N. gorilla n. sp. in Fig. 18); (d) the smooth curve of the anterior border of the posterior hamule; (e) the somewhat convergent cerci with a ventral tooth that is directed straight downwards and thus not visible in dorsal view; and (f) the strongly diverging branches of epiproct. However, it is (1) larger on average, Hw 34.0-35.0 mm (n = 4) rather than 31.0-34.0 mm (n = 4); (2) the abdomen is parallel-sided, with S7-9 scarcely expanded and S8 longer than high or wide; (3) S8-9 are black marked laterally rather contrastingly with yellow, rather than uniformly dark rufous; and (4) the cerci are of rather even width throughout in dorsal view, rather than expanded distally.
