Etymology: Corydoras: Greek, kory = helmet + greek, doras = skin (Ref. 45335); lacrimostigmata: Derived from the Latin words lacrĭma (meaning tear) and stigmata (meaning marks, plural of stigma), in allusion to the diffuse dark stripe between corner of mouth and anterior margin of orbit and the drop-shaped dark blotch on the posterior portion of infraorbital 1, which seem to be tears. A noun in apposition..

Short description
Morfologia | Morfometria
Spine dorsali (totale): 2; Raggi dorsali molli (totale): 8-9; Raggi anali molli: 7; Vertebre: 23. Corydoras lacrimostigmata can be diagnosed from other congeners, except C. carlae, C. ehrhardti, C. flaveolus, C. longipinnis, C. nattereri, C. paleatus, and C. vittatus, in having three nasal pores (vs. two). It differs from C. carlae, C. ehrhardti, C. longipinnis, C. nattereri, C. paleatus, and C. vittatus in having 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). It is distinguished from C. flaveolus in having 16-19 serrations on posterior margin of pectoral-fin spine (vs. 27-36) and 7-10 on posterior margin of dorsal-fin spine (vs. 15-22); and simple serrations on posterior margin of pectoral-fin spine (vs. presence of simple and bifid serrations) (Ref. 95501).
Facultative air-breathing (Ref. 126274)
