maculata, is endemic to the Jequitinhonha and
Pardo rivers in eastern Brazil. Specimens were captured
mostly during the rainy season, in the main channel
and larger tributaries only, specifically in deep
pools at running or backwater sites, and most efficiently
by artisanal fishermen traps made with bamboo and
lianas. Reproduction: Partial spawning
is suggested for the species based on the capture
of individuals in advanced maturation and totally
spawned in distinct temporal periods. Diet:
The diet is diversified and includes mainly allochthonous
resources, especially fruits and terrestrial insects
derived from the riparian vegetation. Colouration:
Its unique life colour pattern, described for the
first time, consist of reddish to olivaceous ground
colour with large whitish vermiculations in small
specimens, and sparse dots in larger ones (Vono et.al.).
Wertheimeria maculata is the only species
in the genus Wertheimeria from the catfish
family Doradidae. Within its restricted range, W.
maculata faces strong human habitat disturbances
such as siltation, habitat fragmentation, pollution,
and introduced species. This fish has been placed
as the sister taxon to all other doradids.
Aquarium Care: Not a lot is known about the
husbandry of this large Dorad but it is being bred
successfully in Brazil by the Brazilian exporter Hudson
Crizanto Gonçalves. Remarks:
All Doradidae examined have retrorse thorns on their
midlateral scutes, except for Wertheimeria,
which lacks thorns. Wertheimeria maculata
Steindachner, 1877 generally has three scutes on the
anterior portion of the body, and the remaining portion
of the lateral line is tubule shaped and unossified,
similar to those found in auchenipterids (Calegari,
B. Barbara et.al. 2019).
