Overview
Described in 1971 by the Dutch ichthyologist Han Nijssen, this corydoras is named after Stanley Weitzman, an American specialist in small characiforms. It has a dark band running through the eye and a large black blotch on the back.
A genetic revision published in 2024 split the old genus Corydoras into several genera: FishBase now places it in Hoplisoma, as Hoplisoma weitzmani.

Observations (GBIF) and localities Native countries Rivers and lakes
FishBase places it in the western Amazon basin, in Peru. Like most corydoras, it lives on the bottom of small streams, among sand, leaf litter and wood.
The parameter ranges given by FishBase are wide: pH 6 to 8, low to medium hardness, 22 to 26 °C.
Behaviour
Peaceful and gregarious like all corydoras, it sifts the substrate in a group for small invertebrates and debris. A group of at least 6 to 8 makes it more active and less fearful; fine sand protects its barbels.
It can breathe air: it is sometimes seen darting up to the surface to gulp a bubble, a normal behaviour in corydoras.
