Taxonomy & naming
Cteniloricaria napova was described by Covain and Fisch-Muller in 2012. The Catalog of Fishes (Eschmeyer, CAS) treats the name as valid, with species id 72274 in the genus Cteniloricaria (genus id 8176). The genus belongs to the subfamily Loricariinae, the whiptail and twig catfishes, within the family Loricariidae.
Cteniloricaria is a small Guiana Shield genus of slender, depressed-bodied loricariines. As with many recently described Loricariinae, the species was distinguished on the basis of plate, odontode, and meristic characters; the detailed diagnosis resides in the original description and is not reproduced here. Beyond the type material and the original work, no data has been published in the readily accessible literature that would expand on its taxonomic history.
Morphology
Cteniloricaria napova reaches about 5 in standard length (SL). Like other members of the genus and subfamily, it has the characteristic Loricariinae body plan: a flattened, elongate form tapering to a long, thin caudal peduncle, the whole animal armoured in rows of bony plates, and a ventral suckermouth.
Beyond overall size and the general loricariine bauplan, detailed morphological data — colour pattern in life, plate counts, fin-ray formulae — has not been published in sources accessible here. Sexual dimorphism has likewise not been described.
Habitat
The species occurs in South America on the Guiana Shield, associated with the Maroni River drainage region. It is a freshwater, demersal, tropical fish — that is, a bottom-dweller of warm running waters, consistent with the rheobiontic habits typical of Loricariinae, which favour current over sand and gravel substrates among submerged structure.
Precise locality, water-chemistry, and seasonal data are sparse in the public record. No quantitative habitat measurements (temperature, pH, conductivity) have been published in sources available here, so none are asserted.
Feeding
No feeding data has been published for Cteniloricaria napova in sources accessible here. By analogy with other small Loricariinae, it is presumably a benthic grazer taking aufwuchs — the biofilm of algae, microorganisms, and fine detritus that coats submerged surfaces — but this is inference from the subfamily rather than an observation specific to this species, and no diet is asserted.
Mating
No data has been published on courtship or mating behaviour in Cteniloricaria napova.
Breeding
No breeding data has been published for Cteniloricaria napova. Many Loricariinae are lithophilic or cavity spawners with paternal care, the male often carrying or guarding the egg mass, but no reproductive observations specific to this species exist in sources available here, so none are claimed.
In the aquarium
Cteniloricaria napova has no established presence in the aquarium hobby. It carries no L-number and does not appear in the ornamental trade in any documented way. Consequently there are no husbandry reports, recommended parameters, or breeding accounts to draw on. Aquarists interested in the genus must extrapolate cautiously from the general needs of small whiptail catfishes — clean, well-oxygenated water with current and fine substrate — while recognising that nothing specific to this species has been published.
Conservation
Cteniloricaria napova has not been evaluated by the IUCN Red List (Not Evaluated). As with many narrowly distributed Guiana Shield loricariids, the absence of an assessment reflects a lack of data rather than confirmed security. Its restricted known range on the Maroni drainage means any future appraisal would depend on better distribution and population information than is currently available.
