Taxonomy & naming
Tympanopleura personata was described in 2026 by Filipe R. V. Ribeiro, Cristiane Silva-Oliveira, Vitor Magalhães, Lucas Gama and Lúcia H. Rapp Py-Daniel, in the Journal of Fish Biology (volume 109, issue 1: 520–530), under a title that names it directly as "a new species of inseminating catfish of the genus Tympanopleura ... revealed by integrative taxonomy." The full text of the paper was not accessible in the sources reviewed here; this article draws only on the species' Catalog of Fishes record and the paper's formal citation.
The species is placed in Tympanopleura within the family Auchenipteridae, subfamily Auchenipterinae — the driftwood catfishes — and Eschmeyer's Catalog of Fishes treats Tympanopleura personata Ribeiro, Silva-Oliveira, Magalhães, Gama & Rapp Py-Daniel, 2026 as a valid, currently accepted name. The holotype (UFOPA-I 1373) and paratypes (INPA 61048, 5 specimens; UFOPA-I 1374, 11 specimens) come from the Iquiri River, a tributary of the Ituxi River within the Purus River drainage, near Lábrea, Amazonas, Brazil (8°59'42.60"S, 66°21'22.04"W).
Morphology
The describing paper's full morphological description — measurements, fin-ray counts, colour pattern and a formal diagnosis — was not accessible in the sources reviewed here; only the Catalog of Fishes record could be consulted, and it reports taxonomic placement and locality data rather than morphometrics. No standard-length figure or other measurement for Tympanopleura personata is available from these sources.
As general context for the genus, not a measurement of this species: Tympanopleura is a genus of small, laterally compressed driftwood catfishes in Auchenipteridae, found across South American Amazon and Orinoco drainages. Species in the genus have historically been difficult to tell apart by external appearance alone, a taxonomic problem that recent integrative studies — combining morphology with molecular data, as the title of this species' own description signals — have been working to resolve.
Habitat
Tympanopleura personata is known from the Iquiri River, a tributary of the Ituxi River within the Purus River subbasin, in the western Amazon basin near Lábrea, Amazonas, northern Brazil. No further ecological detail — substrate, current, or water-chemistry figures — has been published in the sources reviewed here.
Feeding
No diet has been documented for Tympanopleura personata specifically. As general context for the family, not a finding for this species: Auchenipteridae species are typically nocturnal omnivores or invertivores, foraging along the bottom or through open water depending on genus and body shape.
Mating
No direct observations of courtship or mating behaviour have been published for Tympanopleura personata specifically; the sources reviewed here are limited to its Catalog of Fishes record and the formal citation of the describing paper, whose full text was not accessible. As family-level context, not a documented finding for this species: the describing paper's own title identifies T. personata as an "inseminating catfish," and internal fertilisation is a defining reproductive trait of the family Auchenipteridae generally — males possess a modified anal fin used as an intromittent organ to transfer sperm directly to females, who can store it and lay fertilised eggs afterward, one of the few internal-fertilisation strategies known among catfishes. Whether this pattern has been directly confirmed in T. personata, rather than inferred from its generic and family placement, is not established in the sources reviewed here.
Breeding
Breeding is not documented for Tympanopleura personata, and it is not established in the aquarium trade. As family-level context only (see Mating, above): given the auchenipterid pattern of internal fertilisation, any spawning event would be expected to follow females laying eggs externally sometime after internal mating rather than the egg-scattering or nest-building seen elsewhere in Siluriformes — but this is an inference from family biology, not a documented observation of this species.
In the aquarium
Tympanopleura personata is not a trade species. It was described in 2026 from a small series collected in a single Amazonian tributary, and no husbandry or captive-keeping data exists for it specifically. As family-level context, not documentation for this species: driftwood catfishes generally have scaleless skin, which makes them more sensitive than scaled fish to copper-based medications and warrants conservative dosing, and several genera in the family carry stiff pectoral spines that should be handled with a container rather than a net. Whether T. personata has ever been kept in captivity, and what it would need if it were, is unconfirmed.
Conservation
Tympanopleura personata has not yet been assessed on the IUCN Red List, as is typical for a species described in 2026. No conservation recommendation from the describing authors is available in the sources reviewed here — only the Catalog of Fishes record and formal citation were accessible — and its range and any threats to it remain undocumented beyond the single known drainage.
