Description:Dorsal spines (total): 2; Dorsal soft rays (total):
7; Anal soft rays: 5. This species can be diagnosed
from all other congeners by a unique colour pattern
of adults, and from Guianese species by its specific
barcode sequence (JF747005). Colouration:
Colour pattern consists of numerous blackish-brown
spots of irregular size and shape, distributed on
head and on entire body except naked ventral areas,
resulting in a mottled aspect of dorsum, while spots
are aligned to form transverse bands on fins, at least
on caudal fin. Juvenile specimens present large transversal
blackish bands, or dorsal saddles, on the body that
are similar to those characteristic of several Peckoltia
including the type species Peckoltia
spots on posterior part of the body are also present
sabaji, Peckoltia capitulata
and Peckoltia simulata, but in these species
spots are rounded, comparatively larger and regularly
spaced, and they usually do not form bands on fins.
It is further distinguished from these species by
having a deeper body (22.5-25.7% SL, mean 23.8, vs.
less than 23.4 at occiput; 12.4-13.8% SL, mean 13.1,
vs. less than 11.7 at caudal peduncle) and a wider
body (33.8-37.1% SL, mean 35.2, vs. less than 32.7
at cleithrum). Differs from Peckoltia bachi that is
also mottled, by having the eye high on the head (vs.
low) and a much narrower interorbital (29.8-34.4%
HL, mean 32.6, vs. 57.9-59.9, mean 58.8. Habitat:
In rapids, it occurs mostly in sunny and shallow clear
water, swiftly flowing currents, with medium-sized
rocks substrate. Aquarium Care:
Should be kept at slightly higher temperatures and
have a requirement for a higher oxygen intake. Peacfull
inhabitants of an aquarium. Sexual Differences:
Males have bristles behind the gill covers, on the
pectoral fin spines and on the posterior part of the
body. They also posses bristles on the upper caudal
fin rays. Diet: Omnivores, easy to
feed with frozen and live foods and also tablets,
pellets and flake food. Soft wood should be included
in aquarium. Should be kept at slightly higher temperatures
and have a requirement for a higher oxygen intake. Remarks:
The specific name 'otali' is a Wayana Amerindian name
meaning secret, in reference to the colouration of
the species, similar to its biotope, making it difficult
to observe. Wayana Amerindians live on the sides of
the Upper Maroni River basin where the new species
was found. A noun in apposition.
Upper Marowijne River basin in French Guiana and Suriname.
Type Locality: Marowijne River.
