Etymology: Doumea: Taken form a locality, Doumé, in Congo (Ref. 45335); skeltoni: This species is named after Professor Paul H. Skelton, director emeritus of the South African Institute for Aquatic Biodiversity; he has long been a student of the taxonomy and biology of the Amphiliidae (Ref. 94772).
Eponymy: Professor Dr Paul Harvey Skelton (d: 1948) is a South African ichthyologist. [...] (Ref. 128868), visit book page.

背面の脊椎 (合計) : 0; 背鰭 (合計) : 8; 肛門の骨: 0; 臀鰭: 9 - 10; 脊つい: 34 - 37. Diagnosis: Doumea skeltoni is distinguished from all congeners other than D. chappuisi, D. sanaga, and D. thysi in the number of pectoral-fin rays, being 10, rarely 9 or 11, versus 11 to 13 (Ref. 94772). It differs from D. chappuisi in the predorsal length, 38-45% of standard length vs. 32-37%; the body depth at the dorsal-fin origin, 13-16% of standard length vs. 9-13%; and modal value of the number of vertebrae, mode 35 and range 34-37 vs. mode 37 (Ref. 94772). Doumea skeltoni differs from D. sanaga in the predorsal length, 38-45% of standard length vs. 34-37%; the ratio of caudal-peduncle depth to caudal peduncle length, 12-15% vs. 9-11%; the number of vertebrae, 34-37 vs. 38-41; and nearly completely in the head length, 21-26% of standard length vs. 18-21%; and the body depth at the dorsal-fin origin, 13-16% of standard length vs. 10-13% (Ref. 94772). It differs from D. thysi in the caudal-peduncle length, 23-26% of standard length vs. 19-22%; the caudal-peduncle depth, 3-4% of standard length vs. 5-8; the ratio of the caudal-peduncle depth to caudal-peduncle length, 12-15% vs. 25-40%; and the interorbital width, 27-32% of head length vs. 33-38% (Ref. 94772).
