Location

It is native to South America, occurring in smaller rivers that drain into the Aguaytía River, a left‑bank tributary of the Ucayali River in eastern Peru. The Ucayali is one of the principal headwaters of the Amazon River, flowing northward to join the Marañón before forming the main Amazon channel. The Aguaytía basin lies within the Department of Ucayali and encompasses diverse habitats ranging from lowland forests to floodplain systems. The species' presence in these tributaries highlights its role within the complex hydrological network of the western Amazon basin, a region noted for its exceptional biodiversity and ecological significance.

Size

This species reaches a length of 7.1 cm (2.8 in).^[3]

Etymology

The species name derives from the Latin word for 'javelin,' in reference to the vertically elongate, ventrally tapering humeral spot on its side.^[4]
