Dorsal spines (total): 2; Dorsal soft rays (total):
7; Anal soft rays: 4 - 5; Vertebrae: 29. This species
is distinguished from its syntopic congener Hypostomus/Pterygoplichthys
by having dorsal fin with 7 unbranched rays (vs. 10-11),
large dark dots on a clear background (vs. small yellow
dots on a dark background); and median plates 25 or
26 (vs. 27-29). It differs from H. brevicauda
and H. wuchereri by possessing the following
characters: head and trunk covered by conspicuous
dark dots similar in size, ranging from half to approximately
one eye diameter (vs. dots smaller than the pupil);
interradial membranes of anteriormost dorsal-fin rays
with one series of dots (vs. membranes with two or
three series of dots); and ventral surface of body
comparatively weakly covered by plates, with coverage
when present restricted to anterior portion of abdomen
(vs. ventral surface almost or completely covered
by plates, including the central area between pelvic
fins). It can be diagnosed from H. unae by
the presence of conspicuous dots on head, trunk, and
fins similar in size (vs. dots on lateral of trunk
inconspicuous and, when visible, much larger than
those on the head and fins), pectoral spine not distinctly
strong with a few elongated odontodes on its distal
third (vs. pectoral spine distinctly strong with many
elongated and curved odontodes on its distal half),
dorsal fin with tip of last ray, usually reaching
preadipose plate or adipose spine when adpressed (adpressed
fin 36.6-44.3% vs. 29.6-38.7% and tip of last rays
not reaching adipose plate or spine), 47-86 teeth
on premaxilla (vs. 29-70), and 50-81 dentary teeth
(vs. 34-89). It differs from its congeners from coastal
northeastern rivers (H. carvalhoi, H.
eptingi, H. jaguribensis, H. nudiventris,
H. papariae, and H. pusarum) by
a series of characters, including the dark conspicuous
dotted colour pattern of the body and fins, ventral
surface of the belly comparatively weakly covered
by plates, and lobes of the caudal fin relatively
similarly elongated. Habitat: Occurs
in rio Paraguaçu and its tributaries, in stretches
of up to 60 m wide and 1.5 m deep, with rocky bottom,
dark coloured water, mild to fast water current, and
at altitudes ranging from 143 to 350 meters above
sea level. Sympatric with P. chrysostiktos.
Aquarium Care: As with most of this
genus, will do well in a larger aquarium, although
this is one of the smaller species in the genera,
and the aquarium well filtered. Water parameters can
be quite diverse for this genera. Diet:
Omnivore with a liking for green, tablet and frozen
foods. Etymology: Derived from 'îagûara'
in the indigenous language Tupi- Guarani, which means
panther, in reference to the black dotted colour pattern
on a clear background. A noun in apposition.
