Eponymy: In Greek mythology, Hephaestus was the god of fire, blacksmiths, metal-workers and other artisans. De Vis gives no reason for his choice of name. The Corydoras was so named due to the red (fiery) colour of its fins and parts of its body. (Ref. 128868), visit book page.

Description synthétique
Clés d'identification | Morphologie | Morphométrie
This is distinguised by the lack of connection between the posterio process of the parietosupraoccipital and the nuchal plate. There's also a prominent development of a ventral laminar expansion of the infraorbital 1, and the posterior margin of the pectoral-fin spine with serrations along almost its entire length, with an absence in the distal portion. It also has short dorsal and pectoral spines with an unusual color pattern in life.
Found on substrate with sand and dead leaves (Ref. 111516).
