\n

Diapoma nandi<\/i>\u00a0is described from the Piray\u2010Min\u00ed Stream, a tributary of the Rio Paran\u00e1 in Argentina. It is characterized among the Stevardiinae by having a terminal mouth, two unbranched and eight branched dorsal\u2010fin rays, one unbranched and six branched pelvic\u2010fin rays and the absence of a caudal\u2010fin organ and is distinguished from all congeners by the following combination of characters: unmodified scales on the lower caudal\u2010fin lobe, lack of enlarged opercle and subopercle, incomplete lateral line, hyaline adipose fin, anal\u2010fin distal border straight or slightly convex in adult males, large tricuspid teeth on anterior region of the dentary, distal arrangements of the anal\u2010fin bony hooks in adult males, middle caudal\u2010fin rays lacking large round blotch and several morphometric variables associated with body shape. Additionally, we conducted a morphometric comparison focused on the congeners that co\u2010occur in the Paran\u00e1 basin.<\/p>\n
