The other members of Hemigrammus differ by having black pigmentation on the caudal fin either confined to the caudal-fin base (e.g., species belonging to the Hemigrammus ocellifer and Hemigrammus tridens groups, sensu), or as a discrete terminal bar (Hemigrammus marginatus), or finally as symmetrically-arranged black spots on the dorsal and ventral caudal-fin lobes (Hemigrammus bleheri and Hemigrammus rhodostomus) (Ref. 78749).Description: D ii,9; A iv or v, 19, 20, or 22; P i10, 11, or 12; V i7.
