Pentaphlebia mangana Dijkstra, Lambret & Mézière, 2015
Black Relic

Type locality: Mouyanama, Poungui, Gabon

Diagnosis

Male is similar to P. stahli by (a) the long and narrow Pt of 3.0-3.3 mm; (b) the robust cerci with denticulate tips and a well-defined internal subapical blade that is short but wide; and (c) the gradually up-curved paraprocts. However, (1) the body is entirely dark brown to coal black, even at emergence, save the densely pruinose coxae and femoral bases and a few pale yellow-green lines on the thorax with maturity, while P. stahli is largely brick red with yellow thoracic lines; and (2) the subapical blade on the cerci is more rounded.
