Habitat:
Hoplomyzon sexpapilostoma was described from
Masparro river at Masparro dam, Barinas state (Taphorn
and Marrero 1990). It is widely distributed in Western
Andean tributaries of the Orinoco basin, along the
piedmont region from the river Ariari (Guaviare drainage)
to the Guache river in Portuguesa drainage (Taphorn
and Marrero 1990). In Colombia it occurs in rivers
Ariari, Caja, Upamena, Cusiana, and Cravo Norte. In
Venezuela the species is reported from rivers Torbes,
Bumbum, La Yuca, Masparro, Boconó, Guanare,
Las Marías and Guache, all in Apure drainage.
The species has an elevational distribution ranges
from 59-1,406 m above sea level. Diet:
It is presumed to feed on benthic aquatic invertebrates.
Remarks: This species is widespread,
occurring in some protected/conservation areas and
remote regions. The data in biological collections
and different regional reports do not suggest a perceptible
reduction in the populations of the species. Therefore,
it is evaluated as Least Concern (IUCN 2021).
