Etymology: gemma:Name 'gemma' from the ancient Green word meaning 'precious stone' or 'gem', in reference to the body scales appearing iridescent and diamond shape, reminiscent of a tiny gem.

Raios dorsais (total) : 9; Raios anais : 13 - 14. This species is distinguished from its congeners by the following set of characters: a pattern of iridescent, diamond-shaped, light blue spots in scale centres, especially evident below mid-longitudinal series on posteroventral portion of flank, and larger iridescent blue blotches on dorsum, creating an irregular reflective pattern on body of the males; median fins yellow to hyaline, dorsal and anal fins with six to eight dark grey stripes perpendicular to fin rays basally and posteriorly, with light blue iridescence basally; dorsal with light blue distinct margin; anal with dark grey margin; caudal fin with four to five dark grey stripes perpendicular to fin rays; dorsal and anal fins hyaline with irregular brown stripes, fin tips with narrow light blue margin, caudal hyaline without markings in females; and in males: body depth at pelvic-fin origin 25.6-27.4, anal-fin base length 18.7-19.6, head depth 79-83, head width in % of its depth 83-87, caudal peduncle length in % of its depth 111-114 (Ref. 138275). Body shape (shape guide): elongated; Cross section: oval.
This species inhabits a turbid remnant pool in the seasonal Lubule River, 1-2 m wide, with margins overgrown by grass (Ref. 138275).
