Rineloricaria anitae is distinguished from other
species of the genus by the following combination
of characters: the tip of the snout with a bare area
oval not extending backward. Once the eye distance
interorbital; abdomen completely covered by 5-6 series
plates, preceded by smaller cards in the region of
pectoral girdle; pectoral fins reaching in most of
the first third of the pelvis; reaching pelvic the
insertion of anal fin; the margin of the fin flow
with a transverse dark band. This species looks like
R. jaraguensis (Steindachner, 1909) by the
abdomen covered with boards, but is easily the smaller
head size ( -23 21.7% vs. 25.9% -26.6 in the CP).
Differs from R. thrissoceps (Fowler, 1943)
(also with abdomen covered) by the greatest distance
interorbital ( -23.3 21.7% versus 19.8% in CC); R.
quadrensis, R. felipponei (Fowler, 1943)
and R. steindachneri (Regan, 1904) feature
three and four series of plates on abdomen. Looks
like R. henselli (Steindachner, 1907) by
the number of plates in the abdominal series (five),
but differentiates itself by presenting five transverse
strips on the back vs four tracks; looks like R.
microlepidogaster (5-6 sets of abdominal plates),
but differentiates itself by a small naked area oval
(observed in adult specimens) among the latest abdominal
side plates and the abdominal series and to have the
abdominal side plates in uniform abdominal median
vs. graphics in the middle more elongated adjacent
plates. In addition, R. anitae presents the
pelvic and pectoral fins, just touching the base of
the fins adjacent (vs. fins exceed the base of the
fins abutting in R. microlepidogaster).
Aquarium Care: As with all Rineloricaria
provide long leaved plants or bamboo stalks for them
to hang on to. Diet: Omnivore. Vegetable
food such as cucumber and other various foods such
as tablet, flake and frozen. Remarks:
