背棘 (總數) : 0; 背的軟條 (總數) : 11; 臀棘: 0; 臀鰭軟條: 8. Diagnosis: last simple dorsal-fin ray smooth on hind margin; scale formula 4.5-5.5/27-32/4.5; 2.5 scales between lateral line and pelvic-fin base; 12-14 scales around caudal peduncle; 7-8 branched dorsal fin rays; two pairs of barbels; anterior barbell not reaching to anterior margin of eye/not extending beyond centre of eye; posterior barbel reaching to, or extending beyond, posterior half of eye; lateral line complete and deeply depressed below dorsal fin; 4-6 short and widely spaced gill rakers on lower limb of first gill arch; maximum reported size 89 mm SL; 3 small, independent, round spots on sides; 2nd spot located slightly behind vertical line from last simple dorsal-fin ray; average distance centres 2nd-3rd spot/distance centres 1st-2nd spot (= RDT) is over 1.4 (Ref. 2940, 81282).
前面的觸鬚範圍或些微地越過眼的前緣。 在後部達到眼的後半段。 在背鰭之下浸的側線。 通常, 有三個被排列在中央的身體上的小的斑點 (1.) 正好以前背部的,2.) 在垂直的正後方最後背鰭鰭條,3.) 尾柄)- 這是西非型的特性。 在中央的線上的增補的斑點可能出現或在極端方面在中央的線上很多的小點。 背鰭與臀鰭有 3個單一的鰭條。
Three forms exist: West African typical form, Lepidus form with supplementary spots between 3 typical spots and larvae form with numerous aligned points (Ref. 2940).
三個型式存在: 西非典型的, Lepidus 型式在三個典型的斑點之間有額外的斑點與仔魚形式有很多成列的斑點.(見參考文獻 2940)

Estimates based on models
Phylogenetic diversity index (Ref.

50 = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01230 (0.00558 - 0.02710), b=2.97 (2.80 - 3.14), in cm total length, based on LWR estimates for this Genus-body shape (Ref.
