Moenkhausia venerei Petrolli, Azevedo-Santos & Benine, 2016

Family:  Characidae (Characins; tetras), subfamily: Stethaprioninae
Max. size:  3.88 cm SL (male/unsexed)
Environment:  benthopelagic; freshwater
Distribution:  South America: Rio Araguaia basin in Brazil.
Diagnosis:  Dorsal spines (total): 11-11; Anal soft rays: 21-28; Vertebrae: 30-30. Moenkhausia venerei is distinguished from all congeners, except M. collettii and M. copei, by having a conspicuous dark line along the base of the anal fin (vs. dark line absent) and by having a well-marked longitudinal dark stripe extending from the tip of the snout to the base of caudal fin (vs. dark stripe absent). It differs from M. copei by 19-24 branched anal-fin rays (vs. 15-17 in M. copei); and from M. collettii by the possession of more conspicuous and wider longitudinal lateral dark stripe, about a scale deep along the flank (vs. stripe narrow, more restricted to the posterior half of the horizontal septum). Out of the limits of the genus, M. venerei shares similarities with Hemigrammus ulrey, H. barrigonae, and H. ataktos.
