Etymology: Brachyhypopomus: Greek, brachys, eia = short + Greek, hypo = under + Greek, poma, -atos = cover (Ref. 45335);  flavipomus: Derived from the Latin adjective flavus (yellow); and from pomus, latinized from Greek πῶμα = lid, cover, in reference to the conspicuous patches of yellow guanine on the operculum of live individuals..

Short description Identification keys | Morphology | Morphometrics

Anal soft rays: 175 - 186. Brachyhypopomus flavipomus can be distinguished by having conspicuous patches of shiny yellow guanine on the operculum and anterior to pectoral-fin base in live individuals (vs. absent in all congeners) (Ref. 116763).

Biology     Glossary (e.g. epibenthic)

Facultative air-breathing in the genus (Ref. 126274); Occurs only in whitewater floodplain habitats where it is observed throughout the year in floating macrophytes. Most abundant in sheltered floodplain lakes surrounded by high levee forest, but has a patchy distribution, and varies in abundance at a given site from year to year. Occurs sympatrically and syntopically in whitewater floodplain with the following congeners: Brachyhypopomus beebei, B. belindae, B. bennetti, B. brevirostris, B. hamiltoni, B. pinnicaudatus, B. regani, and B. walteri. Exhibits allotopic distributions across parts of its range with Brachyhypopomus batesi, B. benjamini¸ B. hendersoni, B. sullivani, and B. verdii. Feeds on aquatic insect larvae, microcrustacea, and other small aquatic invertebrates, with a predominance of Chironomidae larvae in the type locality (Ref. 116763).

Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00380 (0.00145 - 0.00994), b=3.06 (2.83 - 3.29), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.1   ±0.4 se; based on size and trophs of closest relatives
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
