Etymology: Leptodoras: Greek, leptos = thin + Greek, doras = skin (Ref. 45335).
More on author: Günther.
Issue
Böhlke (1970) briefly discussed taxonomy and relationships. Specimens from Venezuela identified as Opsodoras linnelli (Eigenmann) by Fernández-Yépez (1968:49-50) appear to be closer to L. acipenserinus. Specimens from Rio Orinoco and Rio Negro basins are tentatively identified as Leptodoras acipenserinus and may warrant recognition as one or more distinct species upon thorough revision.
Environment: milieu / climate zone / depth range / distribution range

Dorsal spines (total): 1; Dorsal soft rays (total): 6; Anal soft rays: 14 - 17. Differs from all Leptodoras except L. linnelli by having adipose fin extended anteriorly as a low thin ridge of adipose tissue to a point midway between anterior insertion of adipose fin and posterior insertion of dorsal fin (Ref. 56896).
Body shape (shape guide): elongated.
Inhabits mainly whitewaters, but also occurs moderately in blackwater rivers (Ref. 56896).
