Diagnosis

Diagnosis: Small but very deep-bodied ‘Lampeye’ species with rounded fins; dorsal fin with 9-13 rays, anal fin with 15-19 rays; scales on mid-lateral series 23-24 (Ref. 43268, 57259).

Description: Dorsal fin with 9-13 rays; anal fin with 15-19 rays (Ref. 43268).

Colouration: Male colouration: the general body colour is pale grey-green, the back being grey-brown and the ventral area silver-grey; the scales on the back and the sides have brown edgings; a distinct light blue iridescence is present on the sides, and this is most strongly developed between the eye and the beginning of the dorsal fin; the male has a distinctly deeper body than the female; the unpaired fins are yellow to pale orange or, occasionally, pink, the colour becoming more intense towards the margins; in the posterior parts of the dorsal and anal fins two to three curved, brown bars are present; the caudal fin has a large number of grey-brown spots, arranged in a pattern of crescent-shaped bars (Ref. 57259). Female colouration: translucent grey with a silver abdomen and a light silver iridescence on the frontal part of the sides; scale margins are brown; all unpaired fins are colourless (Ref. 57259). Both sexes have a striking, light silvery-blue iridescent spot in the upper part of the iris (Ref. 57259).
