Habitat: Doras
higuchii is endemic to Brazil and occurs in the
Amazon basin, in the lower Jari River and both upstream
and downstream of the waterfalls of the Trombetas
and Xingu rivers. Etymology: The
genus name Doras: as defined by Lacepède,
doras means cuirass, a piece of armour covering body
from neck to waist (e.g., breastplate), probably referring
to hard bony plates and/or thick, leathery skin (name
does not mean “spear” per Valenciennes
[1840] and others). The specific name higuchii:
in honour of Horácio Higuchi, Universidade
de São Paulo, for his “groundbreaking
contributions” to the systematics of doradid
catfishes. Remarks:
It is possible that the construction of the Cachoeira
Porteira, Belo Monte and Santo Antônio hydroelectric
plants will result in negative local impacts for the
subpopulations present in these rivers. However, the
large calculated extent of occurrence (EOO = 378,361
km 2 ) and the diversity of habitats occupied by the
species indicate that there is no threat capable of
leading it to extinction in a short period of time.
As there are no significant threats to Doras higuchii
, it was categorised as Least Concern (LC), (IUCN
2022).
