Diagnosis. Brachyhypopomus walteri is diagnosed from congeners by the following combination of characters: caudal filament length 27.8-56.4% LEA, vs. 7.4-26.8% in B. batesi, B. belindae, B. bennetti, B. palenque, B. provenzanoi, B. regani, and B. verdii; distinct dark suborbital stripe present, vs. absent in B. alberti, B. arrayae, B. beebei, B. benjamini, B. brevirostris, B. bullocki, B. diazi, B. draco, B. flavipomus, B. gauderio, B. janeiroensis, B. jureiae, B. menezesi, B. occidentalis, and B. pinnicaudatus; accessory electric organ over the opercular region absent, vs. present in B. bombilla; absence of scattered conspicuous black or charcoal flecks on flanks, vs. presence in B. cunia, B. hendersoni, and B. sullivani.

Description. Head and body shape, and pigmentation illustrated in Figs. 1l and 46. Meristic and morphometric data for examined specimens presented in Tables 2-5 and 21. Body shallow to moderate in depth. Head short to moderate in length and shallow to moderate in depth. Dorsal profile of head approximately straight from occiput to snout, ventral profile of head gently convex between operculum and snout, snout rounded. Eye moderate in size. Upper jaw with moderate sigmoidal angle between premaxillary and maxillary portions in lateral view. No accessory electric organ over operculum. Gill filaments on first gill arch 34- 48 (median 39, n = 29). Pectoral fin moderate to broad in width, pectoral-fin rays 12-17 (mode of 15 in populations from the region of the type localities in the central Amazon basin; 14 in populations from the Paraguay basin). Precaudal vertebrae 16-20 (mode of 18 in populations from the region of the type localities in the central Amazon basin, and from the Paraguay basin), including 1-2 transitional vertebrae. Anal-fin origin substantially (0.25-0.33 HL distance) anterior to tip of pectoral fin, never posterior. Anal-fin rays 192-235 (median of 210 in populations from the region of the type localities in the central Amazon basin; 226 in populations from the Paraguay basin). Dorsal rami of recurrent branch of anterior lateral line nerve usually visible. Middorsal region of body scaled. Rows of scales above lateral line 5-7 (mode 7). Lateral line continuous. Depigmented epidermal canals very sparse, almost unnoticeable, found mainly in middle section of body – as curved short lines (usually no more than one) either side of lateral line. Epidermal canals absent from either side of mid-dorsal region, and absent on flank midway from lateral line to dorsal midline. 3-4 bilateral columns at anal-fin terminus and at mid-point between anal-fin terminus and tip of caudal filament in immature, mature female, and mature male specimens. Three or four electrocyte columns sometimes alternate in middle of caudal filament. Caudal filament moderate in length to long.

Coloration. (Figs. 1l, 46). Pigmentation strongly resembles that of B. bennetti. Background pale straw to tan. Dorsal region with irregular brown blotches which extend to irregular-edged and sometimes divided brown bands which extend towards lateral line. No pale mid-dorsal stripe extending from occiput to base of caudal filament. A series of brown blotches is usually present along lateral line. Flank ventral to lateral line and pterygiophore region with very sparse and indistinct disrupted vertical bands. Caudal filament darker than body, with indistinct dark blotches and disrupted vertical bands, often with darkened tip; darkened tip of caudal filament resembles root tips of water hyacinths when viewed underwater. Head darker, especially dorsally. Eye with prominent suborbital patch of chromatophores and subcutaneous pigmentation (rarely indistinct, never absent). Pectoralandanal-finmembraneshyaline. Pectoralandanal-fin rays hyaline with light scattering of brown chromatophores. Anal-fin ray pigmentation darker in posterior half of fin. Color in live individuals similar to preserved specimens, body sometimes with yellow-green tinge in waters with high sediment load, opercular region usually very rosy due to underlying gills.

Size. A Brachyhypopomus of moderate adult size, largest specimen examined 215 mm TL, ca. 150 mm LEA (n = 1,400). Largest male specimen examined 195 mm TL, 136 mm LEA (n = 25). Largest female specimen examined 201 mm TL, 140 mm LEA (n = 55).

Sexual dimorphism. No salient sexual dimorphism in size. Breeding males develop elongated caudal filaments in comparison to immature individuals and breeding females (Fig. 46a,b), but do not exhibit an elevated number of horizontal bilateral columns or vertical rows of electrocytes. Instead breeding males exhibit clearly enlarged electrocytes relative to immature specimens and females. Tip of caudal filament in large males never exhibits a paddle-like lateral compression. No sexual differences in pigmentation.

Geographic distribution. Bolivia, Brazil, Ecuador, Guyana, Paraguay, and Peru (Fig. 47). Widely distributed through the Amazon basin, including whitewater, clearwater and blackwater systems. Also known from the middle Essequibo, and from the Paraguay-Paraná drainage. Records from the Paraná-drainage are mostly from collections in the Pantanal Matogrossense in the northern río Paraguay, but a single specimen was collected from the río Paraná of Paraguay, at a latitude of 27°17'03"S. Sullivan et al. (2013) did not report B. walteri from the Paraná-Paraguay drainage.

Population variation: We found overlap in the range of meristic counts(Tables 2-5) and morphometric measurements (Table 21), and observed similar pigmentation among populations of B. walteri from the central Amazon and from the upper Paraguay. These observations, in combination with molecular data (Crampton et al., 2016), support the hypothesis that all populations we have assigned to B. walteri are members of a single geographically widespread species, which is morphologically and genetically distinct from all congeners.

Ecological notes. Brachyhypopomus walteri is an ecologically cosmopolitan species that occurs in both high-conductivity and low-conductivity systems, but is usually more abundant in low-conductivity systems. It is a common component of floating meadow habitats in the high-conductivity whitewater floodplains of the Amazon River and its whitewater tributaries, and also along the margins of low-conductivity blackwater rivers such as the rio Negro, and rio Tefé. In the central and upper Amazon, in the vicinity of Tefé, Brazil, and Iquitos, Peru, B. walteri is much more common in floating meadow communities of normoxic low-conductivity blackwater systems than in seasonally hypoxic high-conductivity whitewater systems. Populations from central Amazon whitewater floodplains are able to tolerate protracted periods of experimentally induced hypoxia by undertaking aerial gill respiration (Crampton, 1998b). Brachyhypopomus walteri is also abundant in small low-conductivity terra firme rivers and streams, where it is associated with aquatic vegetation and submerged root masses and leaf litter. Sullivan et al. (2013) infer, incorrectly, that B. walteri is predominantly a white-water floodplain specialist that occurs in blackwater systems only near their confluence with whitewater systems. For instance, contrary to Sullivan et al. (2013), B. walteri is known from the rio Negro far from its confluence with the Amazon River near Manaus (Fig. 47). Breeding occurs during the rising and high water period in populations from Amazonian floodplain floating macrophytes (Crampton, 1996a: 165). Stomach contents in populations from the central Amazon comprise aquatic insect larvae, microcrustacea, and other small aquatic invertebrates – with a predominance of Chironomidae larvae (Crampton, 1996a: 136).

Co-occurring congeners: Because of its wide geographical range and occurrence in multiple habitats, B. walteri occurs in geographical sympatry and ecological syntopy with multiple congeners: in the Amazonas drainage, rio Essequibo, and coastal drainages of the Guianas: B. alberti, B. arrayae, B. batesi, B. beebei, B. belindae, B. benjamini, B. bennetti, B. bombilla, B. brevirostris, B. bullocki, B. cunia, B. flavipomus, B. hamiltoni, B. hendersoni, B. pinnicaudatus, B. regani, B. sullivani, and B. verdii; and in the río Paraná-Paraguay drainage with B. bombilla, B. brevirostris, B. draco, and B. gauderio.
