背面の脊椎 (合計): 0; 背鰭 (合計): 7; 肛門の骨 0; 臀鰭: 8 - 10. Diagnosis: Doumea stilicauda 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 (Ref. 85844). Doumea stilicauda differs from D. chappuisi in predorsal length 27-30% of standard length, vs. 32-37%; head length 15-17% of standard length, vs. 19-23%; caudal-peduncle length 35-41% of standard length, vs. 22-29%; and caudal-peduncle depth 19.6-25.8 times in caudal-peduncle length, vs. 7.3-14.5 times (Ref. 85844). Doumea stilicauda differs from D. reidi in predorsal length 27-30% of standard length, vs. 33%; head length 15-17% of standard length, vs. 18%; caudal-peduncle length 35-41% of standard length, vs. 22-29%); and caudal-peduncle depth 19.6-25.8 times in caudal-peduncle length, vs. 11.8 times (Ref. 85844).
It is found in a 'blackwater' rainforest system with low pH waters, its mean pH 6.2 (Ref. 85844).
