Paragomphus clausnitzerorum Dijkstra, Mézière & Papazian, 2015
Gabon Hooktail

Type locality: Franceville-Kessala Road, second stream E of Onkoua, Gabon


Male recalls P. nigroviridis by (a) the largely black face including the occiput; (b) the largely black thorax with prominent green postdorsal, mesepimeral and metepimeral stripes, but reduced antehumeral and metepisternal stripes; (c) the postdorsal stripes fused to the collar, together appearing like an inverted seven; and (d) the apices of the cerci that diverge in dorsal view. However, (1) may be slightly larger, Hw 24.5-26.0 mm (n = 5) rather than 23.5-24.0 mm (n = 2); (2) the black labrum typically bears a pair of green spots, rather than having these fused into a single bar; (3) the antehumeral stripe is usually completely absent, rather than reduced to a spot that lies close to the dorsal end of the postdorsal stripe; (4) in lateral view the cerci are more markedly curved up in their basal half and down in their apical half, with a prominent angle between these halves dorsally; and (5) the tips of the cerci are more strongly curved and relatively thick and rounded, with four large and equal teeth, rather than curved more gradually, tapering to a slender and truncated tip with about seven smaller teeth, of which the most terminal stands apart and is often longer.
