| Africa: only known from the So'o River, a tributary of the Nyong River, in Cameroon (Ref. 85844). |

This species is distinguished from all its congeners except D. chappuisi and D. reidi by having the dorsolateral and ventrolateral vertebral processes extending through the dermis to form longitudinal bony ridges from slightly anterior to the base of the adipose fin posteriorly to the caudal-fin base and from somewhat anterior of the anal-fin origin to the caudal-fin base. The exposed processes are in shape of longitudinal bars with slightly corrugated surfaces that together form irregular longitudinal ridges. Doumea stilicauda differs from D. chappuisi in predorsal length 27-30% SL (vs. 32-37%); head length 15-17% SL (vs. 19-23%); caudal-peduncle length 35-41% SL (vs. 22-29%); caudal-peduncle depth 19.6-25.8 times in caudal-peduncle length (vs. 7.3-14.5 times). D. stilicauda differs from D. reidi in predorsal length 27-30% SL (vs. 33%); head length 15-17% SL (vs. 18%); caudal-peduncle length 35-41% SL (vs. 22-29%); caudal-peduncle depth 19.6-25.8 times in caudal-peduncle length (vs. 11.8 times) (Ref. 85844). |
| The Nyong River is a 'blackwater' rainforest system with reported low pH waters (mean pH 6.2) (Ref. 85844). |
