Corydoras flaveolus not Ihering, 1911. - Graça & Pavanelli, 2007: 10, 113, 114 [Brazil, Paraná State, checklist, identification key, brief description, distribution, maximum standard length, photo in lateral view]
A new species of Corydoras Lacépède, 1803 (Siluriformes: Callichthyidae) from the upper rio Paraná basin, Brazil
description
Description. Morphometric data presented in Table 1. Head compressed with slightly convex dorsal profile; triangular in dorsal view. Snout slightly pointed. Head profile convex from snout to tip of posterior process of parieto-supraoccipital. Profile slightly convex along dorsal-fin base. Postdorsal-fin body profile concave to adipose-fin spine; concave from this point to caudal-fin base. Ventral profile of body nearly straight from isthmus to pectoral girdle; slightly convex from this point until pelvic girdle. Profile nearly straight from pelvic girdle to base of first anal-fin ray; slightly concave until caudal-fin base. Body roughly elliptical in cross section at pectoral girdle, gradually becoming more compressed toward caudal fin. Eye rounded, located dorso-laterally on head; orbit delimited dorsally by frontal and sphenotic, ventrally by infraorbitals. Anterior and posterior nares close to each other, only separated by a flap of skin. Anterior naris tubular. Posterior naris close to anterodorsal margin of orbit, separated from it by a distance equal to diameter of naris. Mouth small, subterminal, width nearly equal to bony orbit diameter. Maxillary barbel short, not reaching

diagnosis
Diagnosis. Corydoras lacrimostigmata can be distinguished from its congeners, with exception of C. carlae, C. ehrhardti, C. flaveolus, C. longipinnis, C. nattereri, C. paleatus, and C. vittatus, by the presence of three nasal pores (vs. two). The new species can be distinguished from C. carlae, C. ehrhardti, C. longipinnis, C. nattereri, C. paleatus, and C. vittatus by the presence of four to six small rounded black blotches along the midline of flank (vs. midline of flank with three large black blotches in C. carlae, C. ehrhardti, C. longipinnis, and C. paleatus; longitudinal dark stripe in C. nattereri; and anterior portion spotted and posterior portion with posterior margin of plates blackened, forming a rough dark stripe in some specimens of C. vittatus). The new species can be distinguished from C. flaveolus by the lower number of serrations on posterior margin of pectoral-fin spine (16 - 19 vs. 27 - 36) and on posterior margin of dorsal-fin spine (7 - 10 vs. 15 - 22); and by the presence of simple serrations on posterior margin of pectoral-fin spine (vs. presence of simple and bifid serrations). See additional diagnostic features in discussion.
