Pentaphlebia gamblesi Parr, 1977
Type locality: Obudu Plateau, Nigeria
Known only from the male holotype, which differs from P. stahli by (1) 3-4 Ax in each wing, rather than 5-7 Ax;
(2) Pt swollen with posterior margin strongly convex, rather than narrow with straightish posterior margin; (3) cerci more than (rather than less) 2x as long as S10, their apices smooth with long and shallow subapical blade, rather than spiny apices with short and deep subapical blade; (4) only extreme tips of paraprocts upturned, rather than entire apical half (lateral view).
Streams shaded by forest. Probably especially faster sections (rapids, falls) with rocks. Recorded at around 1500 m above sea level.
