This genera is identified by the teeth of the upper
mandible being twice as long as the lower mandible.
The upper lip is short, its edge covered by numerous
thin, simple, bifurcate or, more rarely, trifurcate
barbels. The lower lip has small papillae with long
filaments along the edge. The leading ray of the pectoral
fins are longer and the upper first spine of the caudal
fin is extended. Males have an enlarged lower lip
which aids the guarding of the cluster of eggs. This
species can be diagnosed from all congeners, except
Loricaria coximensis, L. holmbergi,
and L. pumila, by possessing large and tightly
joined plates confined to median abdominal space between
lateral abdominal plates, with pectoral girdle entirely
naked or occasionally with small isolated plates near
base of pectoral fin (vs. plates covering the entire
median abdominal space and pectoral girdle, usually
with a V-shaped anterior margin). It differs from
L. pumila by having a larger adult size (13-19
cm vs. less than 8.5 cm SL), iris operculum present
(vs. absent), and larger eye size (minimum orbital
diameter 16.2- 19.4% vs. usually less than 13.3% of
HL); from most similar species L. coximensis
and L. holmbergi by having a larger adult
size (13-19 cm SL vs. usually less than 13 cm SL)
and larger post-ural plate length (17.0-20.3% vs.
7.4-14.2% of HL); and further distinguished from L.
coximensis by having 32-33 lateral plates (vs.
28-31). Habitat: Occurs in flowing
water habitats ranging from small, seasonally intermittent
streams (arroyos) to large permanent rivers. Collected
from the following localities: repeatedly in small
order streams with clear water in the upper Rio Miranda
drainage within the boundaries of the Parque Nacional
da Serra da Bodoquena; in and above riffles at depths
of 0.3-1.5 m in the Aquidaban and Tebicuary drainages;
in black water at the edge of the main river channel
in swift current over sand and mud substrates in the
rio Negro at the southern end of the Pantanal wetlands;
along the shore over substrates of sand, silt and
mud, at a depth of less than 1.5 m using seine at
night in the lower Rio Paraná. Aquarium
such as sand is beneficial. High oxygen levels, frequent
water changes and strong filtration is called upon.
Provide plants and bogwood for shelter. Diet:
South America:Throughout the Rio Paraguay basin of Bolivia,
Brazil, and Paraguay, south to its confluence with
the Rio Paraná in Argentina.
