Dorsale zachte stralen (totaal) : 7 - 9; Anale zachte stralen: 9 - 11; Wervels: 31 - 32. Diagnosed by the following combination of characters: female urogenital papilla curved to the right, located laterally; border of the anal aperture in contact with the first anal-fin ray or very close to it; absence of the right hook and presence of the left one; gonopodial appendix asymmetrical, its halves different from each other, right half wider than left one; absence of a caudal peduncle spot; presence of a wide and square-shaped lateral spot in large specimens; rectangular tip of hook on left half of gonopodial appendix; lateral spot in adult females very narrow, forming a vertically elongated bar covering up to the length corresponding to two scales length in horizontal direction and 2-4 scales in vertical direction; background coloration light brown or yellow; and margin of scales on prepelvic region not visible, not bordered by dark chromatophores, forming a light, plain yellow region; and lateral spot absent or small and discrete not covering one or two scales in horizontal or vertical directions (Ref. 76852).
