Clés d'identification | Morphologie | Morphométrie
Rayons mous dorsaux (Total) : 15 - 16; Rayons mous anaux: 13 - 14; Vertèbres: 46 - 48. In fish measuring 6 cm SL or more, aggregation of luminous tissue on head appear as a band across gill cover; one or several luminous patches on flanks, close to the medial line of body in advance of pelvic fin insertion. Chin barbel shorter than head, its swollen tip forming wide flattened lobe with oblique ribs and with small medial notch. It differs from other species of the group in having more vertebrae (Ref. 27676).
Body shape (shape guide): elongated.
