Diagnosis: posterior tip of upper jaw extending to below posterior margin of eye or beyond (Ref. 57403), 79590). 63-136 long, slender, unicuspid setiform teeth on each half (left and right) of upper jaw, with alternate teeth usually staggered in 2 rows (although it may be difficult to easily distinguish these rows as separate)(Ref. 79590), not separated by median tubercle (Ref. 57403, 79590).
Larvae ascend rivers, adults in freshwater (Ref. 4343). Amphidromous endemics living as adults in clearwater streams of the volcanic islands in the Gulf of Guinea and of Mount Cameroon streams in Western Cameroon (Ref. 92840).

Estimates based on models
Phylogenetic diversity index (Ref.
82804): PD
50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00389 (0.00180 - 0.00842), b=3.12 (2.94 - 3.30), in cm total length, based on all LWR estimates for this body shape (Ref.
93245).
Ελαστικότητα (Ref.
120179): Υψηλό, ελάχιστος χρόνος για διπλασιασμό πληθυσμού < 15 μήνες (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref.
59153): Low vulnerability (10 of 100).
