Chaves de identificação | Morfologia | Morfometria
Raios dorsais moles (total) : 8; Raios anais moles: 8 - 10; Vértebras: 31 - 32. Can be diagnosed by the following combination of characters: the 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; rounded tip of the hook on left half of gonopodial appendix; hook on left appendix very small; absence of a caudal peduncle spot; presence of a wide and square-shaped lateral spot in large specimens; lateral spot in adult females elliptical to roundish, but never forming a vertical bar; lateral spot always present and evident not covering more than the length corresponding to two scales length in horizontal or vertical directions (Ref. 76852).
