Diagnosis. Brachyhypopomus bombilla is diagnosed from congeners by the following combination of characters: presence of accessory electric organ over the opercular region, vs. absence in all congeners except B. menezesi and B. regani ; dorsal surface uniformly speckled with small brown chromatophores on a pale background, vs. presence of large dark blotches against a lighter background in B. menezesi and B. regani .

Description. Head and body shape, and pigmentation illustrated in Fig. 15 View Fig and in the original description. Meristic and morphometric data for examined specimens are presented in Tables 2-5 and 9. 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, concave above eye, ventral profile of head straight, snout truncated to rounded. Eye small to moderate in size. Upper jaw with slight sigmoidal angle between premaxillary and maxillary portions in lateral view. Accessory electric organ (AEO) over operculum present; skin over AEO with similar pattern of chromatophores to surrounding area, obscuring margin of AEO and rendering AEO difficult to see in most specimens. Gill filaments on first gill arch 29-34 (median 32, n = 6). Pectoral fin narrow to moderate in breadth, pectoral-fin rays 14-17 (mode of 15 in populations from Patos-Mirim lagoon system and upper Madeira, mode of 14 in populations from Uruguay drainages). Precaudal vertebrae 15-18 (mode of 18 from Patos-Mirim, 16 from río Paraguay drainages of Brazil and Paraguay, and 17 from upper Madeira), including 1-2 transitional vertebrae. Anal-fin origin slightly (<0.25 HL distance) anterior or posterior to, or near, tip of pectoral fin. Anal-fin rays 155-193 (median of 183 in populations from Patos-Mirim, 171 from río Paraguay, and 176 from upper Madeira). Dorsal rami of recurrent branch of anterior lateral line nerve not visible. Middorsal region of body scaled. Rows of scales above lateral line 5-7 (mode 6). Lateral line continuous. Multiple groove-like depigmented epidermal canals, some with dark borders, form parallel striations mostly dorsal to lateral line in posterior portion of body, beginning ca. two thirds of LEA; striations reaching 1-4 scales (including lateral line series) dorsally, and occasionally (with much lower density) 1-2 scales ventrally. Epidermal canals absent in anterior portion of body, never form a pair of long irregular lines either side of dorsal surface in dorsal portion of flank, and do not form isolated horizontal wavy line midway from lateral line to dorsal midline in midbody or anterior portion of body. Three bilateral horizontal columns of electrocytes 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. Electrocytes of hypaxial electric organ extend anterior to anal and urogenital pores and appear to extend into opercular area to form paired accessory electric organ. Caudal filament short to moderate in length.

Coloration. ( Fig. 15 View Fig ). Background pale straw. Dorsal region with more or less homogenous speckling of small brown chromatophores, declining in density ventrally. Dorsal region without pale stripe extending along midline from occiput to base of caudal filament. Flank ventral to lateral line only sparsely pigmented with irregular small clusters of brown stellate chromatophores. Caudal filament darker. Hypaxial electric organ conspicuous in posterior half to third of body. Head with evenly scattered dark chromatophores, darker dorsally. Eye usually with suborbital patch of subcutaneous pigmentation, of varying darkness and prominence. Region around lips usually depigmented. Presence of chromatophores over entire operculum disrupts borders of AEO, rendering it difficult to see in many specimens. This may account for why the authors of the original description failed to report the presence of this important character (although we inspected the holotype and found the AEO conspicuous). Pectoral and anal-fin membranes hyaline. Pectoral-fin rays hyaline. Anal-fin rays with uniform light brown pigmentation near bases, hyaline distally. Color in life faintly yellow in individuals from sediment-rich waters, with opercular region usually rosy due to underlying gills.

Size. Small to moderate adult size, largest specimen examined 161 mm TL, 140 mm LEA (n = 537). Largest male specimen examined 161 mm TL, 140 mm LEA (n = 13). Largest female specimen examined 147 mm TL, 124 mm LEA (n = 43).

Sexual dimorphism. No known secondary sexual dimorphism.

Geographic distribution. Argentina, Bolivia, Brazil, Paraguay, Peru, and Uruguay ( Fig. 16 View Fig ). Known from the Patos-Mirim lagoon system, Uruguay drainage, Paraná below the former Guaíra Falls, lower and upper Paraguay, and upper Madeira (Amazon drainage) above its major series of rapids beginning at the Salto Santo Antônio (near Porto Velho, Rondônia, Brazil).

Population variation: We found complete overlap in the range of meristics ( Tables 2-5) and morphometric proportions ( Table 9), and observed similar pigmentation among populations of B. bombilla in the Patos-Mirim system, Paraguay dr., and upper rio Madeira. These observations, in combination with molecular data ( Crampton et al., 2016), support the hypothesis that all populations we have assigned to B. bombilla are members of a single geographically widespread species, which is morphologically and genetically distinct from all congeners (although we were unable to obtain specimens for genetic analyses from the type locality in the Laguna Merín drainage).

adapted to a wide range of temperature, conductivity, and other parameters. In high latitudes it exhibits a period of dormancy in the austral winter, which is apparently unique among congeners (Giora et al., 2011). At this time it burrows in muddy substrates, slows its EOD, ceases to forage, and exhibits arrested gonadal development (Giora et al., 2011). Stomach contents in populations from southern Brazil (Giora et al., 2011) and from the upper Madeira (WGRC pers. obs.) comprise mostly aquatic insect larvae, microcrustacea, and other small aquatic invertebrates.

Co-occurring congeners: In the upper Madeira B. bombilla occurs in geographical sympatry and ecological syntopy with B. arrayae , B. brevirostris , B. pinnicaudatus , and B. walteri . It also exhibits an allotopic distribution with B. alberti and B. sullivani . In the upper portions of the Paraguay, B. bombilla co-occurs in sympatry and syntopy with B. brevirostris , B. draco , B. gauderio , and B. walteri . In the lower Paraná, B. bombilla co-occurs in sympatry and syntopy with B. draco , B. gauderio and B. walteri . In the lower portions of the Paraguay, and in the Patos-Mirim system, B. bombilla co-occurs in sympatry and syntopy with B. draco and B. gauderio .

Local names. Argentina, Paraguay: morenita; Bolivia: Cuchillo; Brazil: tuvira, moreninha (southern Brazil); Peru: macana; Uruguay: morenita, limpiavidrio ( Nion et al., 2002).

Ecological notes. Brachyhypopomus bombilla occurs in floodplains, swamps and along the edges of slow-moving creeks and rivers – always in association with dense root mats of floating aquatic vegetation ( Almirón et al., 2010; Giora et al., 2011; Koerber, 2011; Loureiro & Silva, 2006). Giora et al. (2011) document the reproductive ecology of B. bombilla from southern Brazil. Breeding occurs during the austral spring and summer. In the upper Madeira, WGRC collected B. bombilla during the low water period from floating aquatic vegetation in floodplain pools and channelmargins of the río Beni floodplain (conductivity ca. 150 μScm-1, pH 7.3-7.6, dissolved oxygen 5-6 mgl-1, temperature ca. 28-32°C). Hagedorn & Keller (1996) report B. bombilla (identifications confirmed from voucher specimens at the USNM) from creeks of upper Madeira drainages in Peru. In the Paraná-Paraguay drainage, collection records indicate that B. bombilla is found in a variety of habitats, including swamps, riverine floodplains and slow-flowing creeks. Throughout its range B. bombilla appears to be Material examined. 527 specimens. Argentina. Corrientes. AI 267, 10, 91-132 mm, Esteros del Iberá, Laguna Galarza, Paraná dr., 28°04′56″S, 056°42′04″W.
