簡短描述
型態特徵 | 形態測量圖
背棘 (總數): 0; 背的軟條 (總數): 14-19; 臀棘 0; 臀鰭軟條: 25 - 31. Dorsal base 0.41-0.68 x anal fin base. Pectorals as long as head, posterior end does not extend origin of pelvic fins. Caudal peduncle thin, height 14.4-22.9x of SL. Dark grey-black or brown coloration.
Affinities: Brienomyrus longianalis. Occurs in most coastal basins in West Africa (Ref. 2703). Within this species complex, four distinct waveforms of electric organ discharge (EOD) were noted in the Gabon (Ivindo River) populations, probably pointing to separate species (Ref. 10460). Exhibits sexual dimorphism in its EOD waveform and duration (Ref. 10011; 10764 ). EOD has a constant waveform and variable sequence of pulse intervals (SPI) (Ref. 55567).
