Schizolecis
species of fish
Schizolecis is a monospecific genus freshwater ray-finned fish belonging to the family Loricariidae, the suckermouth armoured catfishes, and the subfamily Hypoptopomatinae, the cascudinhos. The only species in the genus is Schizolecis guntheri, a species which is endemic to Brazil.
Taxonomy
Schizolecis was first proposed as a genus in 1984 by the Brazilian ichthyologists Heraldo A. Britski and Julio C. Garavello with Microlepidogaster guntheri as its only species, and designated as its type species. M. guntheri was first formally described in 1918 by the Brazilian zoologist Alípio de Miranda Ribeiro with its type locality given as the Ilha de Sao Sebastiao in the Brazilian state of São Paulo. Eschmeyer's Catalog of Fishes classified the genus Schizolecis in the subfamily Hypoptopomatinae, the cascudinhos, within the suckermouth armored catfish family Loricariidae.
Etymology
Schizolecis combines Schizo meaning "split" or "cleave" with lekos , which in this case the autors say means "plate", a reference to the plates on the sbout being the same size as those on the head. The specific name honours the specimen collector Francisco Günther, who collected specimens for the Museu Paulista, University of São Paulo, including holotype of this catfish.
Distribution and habitat
Schizolecis occurs mainly in coastal rivers of the Atlantic Forest in southeastern and southern Brazil. These fish inhabit streams with rocky and sandy bottom, mostly in shallows and backwaters up to 30 centimetres (12 in) deep, with slow water flow.
Appearance and anatomy
Schizolecis reaches a maximum length of 4.0 centimetres (1.6 in) SL in males and 3 cm (1.2 in) SL in females.
This brief starts where responsible research should: with the source description of “Schizolecis” as species of fish. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the science & nature register because the source frames it as species of fish. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Stable identifiers, scientific names and standards terminology offer the best bridge between this overview and specialist evidence. The source revision retrieved here is dated Jul 6, 2026. The linked authority identifier is Q3764987. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1984 and 1918.
Current terminology should not be projected backward without checking the classification used when the underlying evidence was created. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
How to read it
Check terminology, classification and the date of the cited evidence. Scientific names and technical consensus can change while older records retain historical value.
