[...] Margit Zarske is the senior author’s wife. She is a graduate teacher who, according to her husband, “…for many years has endured and supported my passion for ichthyology”.

背棘 (总数) : 2; 背的软条 (总数) : 9; 臀棘: 3 - 4; 臀鳍软条: 29 - 34; 脊椎骨: 34 - 35. Medium-sized species of Moenkhausia distinguished by the following characters: maxilla longer than snout; 1-2 broad, tri-cuspid maxillary teeth; anal fin with 29-34 branched, relatively long rays; small hooks present on rays of anal fin in males; scales relatively large, 34-36 in longitudinal series; 6.5-7.5 vertical scales before dorsal fin origin; first third of caudal origin covered with small, specialized scales; pre-ventral region rounded; shoulder spot rounded and prominent; no black spot on caudal peduncle; no black saddle-spot before origin of dorsal fin; no silver longitudinal band on side of body. 'Spines' refer to unbranched rays.
