A new shallow-bodied species of Moenkhausia is described from the upper Rio Negro, Amazon basin, Brazil. The new species is diagnosed from all congeners by the combination of a body depth not surpassing 33% in SL in adult specimens, seven scale rows between dorsal-fin origin and lateral line, five scale rows between pelvic-fin insertion and lateral line, a single conspicuous vertically elongated humeral blotch, and a conspicuous caudal peduncle blotch extending to the distal margin of the median caudal-fin rays. The new species was collected together with Jupiaba zonata, with which it shares a very similar color pattern. The similarity between these two taxa is interpreted as an additional case of Batesian mimicry between Moenkhausia and Jupiaba.

Two new species of Jupiaba Zanata are described from Brazil. Jupiaba iasy, new species, is described from rio Teles Pires and rio Jamanxim, tributaries of rio Tapajós, and from rio Aripuanã, in the rio Madeira drainage. It is distinguished from its congeners by its color pattern consisting of a single posteriorly displaced dark crescent-shaped humeral blotch, situated over the first 5 to 7 lateral line scales, and an inconspicuous dark spot at the end of caudal peduncle. It also differs from all remaining Jupiaba for the following combination of characters: 34-36 lateral line scales, 19–21 branched anal-fin rays, 8–10 predorsal scales arranged in a regular row, 6 horizontal series of scales above and 4 series below lateral line, body depth 32.3–36.1% of SL, and absence of filamentous rays in the first dorsal and anal-fin rays. Jupiaba paranatinga, new species, is described from rio Teles Pires, tributary of rio Tapajós. It is distinguished by having 34–35 lateral line scales, two vertically elongated humeral blotches, a conspicuous caudal spot at the end of the caudal peduncle, extending over 8–10 median caudal-fin rays, eye diameter 43.7–46.9% of HL, and relatively low body depth (31.3–35.5% of SL). Additionally, comments on the putative relationships of the new species with their congeners and an updated key to the species of the genus are provided.

ABSTRACT A new species of Astyanax from tributaries of the rio de Contas, Bahia, Brazil, is described. The new species differs from congeners by having three horizontal series of scales from lateral line to pelvic-fin origin and the distal margin of third infraorbital distinctly separated from vertical and horizontal limbs of preopercle, leaving a broad area not covered by superficial bones. The new species further differs from most congeners by the presence of bony hooks on all fins of mature males. Particularly from congeners occurring in rivers of the Northeastern Mata Atlântica freshwater ecoregion, it further differs by having the highest body depth just anterior to the dorsal-fin origin, 34-37 pored lateral line scales, a vertically elongated conspicuous dark humeral blotch reaching below the lateral line and a conspicuous dark wide midlateral stripe extending from the clear area on the rear of the humeral blotch to the end of middle caudal-fin rays and forming an inconspicuous blotch on caudal peduncle.

Astyanax goyacensis Eigenmann, 1908 is redescribed based on the holotype and 25 topotypes. The species belongs to the A. bimaculatus species complex, sharing with those species a black, horizontally ovate, humeral spot (the most conspicuous feature of this complex), two diffuse vertical brown bars in the humeral area (the first through humeral spot and the second 2-3 scales behind), and black medium caudal-fin rays. Furthermore, A. goyacensis possesses a black stripe extending along midlateral body portion, more conspicuous in alcohol preserved specimens. These characteristics allow its inclusion in the putative "black lateral stripe" sub-group of A. bimaculatus species complex. From the species of this complex it differs by the black lateral stripe shape, pattern of chromatophores on the flank, coloration of the caudal fin, scales on the lateral line, branched rays on anal fin, eye diameter, and caudal peduncle depth. Comments about the color pattern in Astyanax bimaculatus species complex are added.

The genus Homalopteroides Fowler 1905 is resurrected and distinguished from the genus Homaloptera van Hasselt 1823based on a combination of characters including a unique mouth morphology, dorsal-fin origin over pelvic fin,≤60 lateral-line scales, and≤30 predorsal scales. Species included in Homalopteroides are H. wassinkii (Bleeker 1853), H. modestus(Vinciguerra 1890), H. rupicola (Prashad & Mukerji 1929), H. smithi (Hora 1932), H. stephensoni (Hora 1932), H. weberi(Hora 1932), H. tweediei (Herre 1940), H. indochinensis (Silas 1953), H. nebulosus (Alfred 1969), H. yuwonoi (Kottelat1998), and possibly H. manipurensis (Arunkumar 1999). Homalopteroides modestus (Vinciguerra 1890) is a poorlyknown species that was originally described from the Meekalan and Meetan rivers of southern Myanmar. It occurs in theSalween, Mae Khlong, and Tenasserim basins, and can be distinguished from all other species of Homalopteroides by thecombination of caudal-fin pattern (black proximal and distal bars, median blotch), 15 pectoral-fin rays, pectoral-fin lengthgreater than head length, 5½–6½ scales above and 5–6 scales below the lateral line (to the pelvic fin), 39–44 total lateral-line pores, no axillary pelvic-fin lobe, pelvic fin not reaching anus, orbital length less than interorbital width in adult, and maxillary barbel reaching to or slightly past the anterior orbital rim.

ABSTRACT A new Metynnis is described from the rio Negro in Brazil and Venezuela, and from black- or clearwater tributaries in Brazil including the rios Parauari, Uatumã, Trombetas, and Sucunduri (the latter belonging to the rio Madeira basin). The new species can be distinguished readily from all congeners by having a high concentration of dark chromatophores on the lateral line scales. It can be further distinguished by the combination of head length 24.3-27.5% of SL, 13-18 gill-rakers on upper limb and 16-24 gill-rakers on lower limb. The new species is most similar to and likely most closely related to Metynnis hypsauchen . These two species share a similar color pattern, body shape and sexual dimorphism of the anal fin. However, they differ in that M. hypsauchen has a lightly pigmented lateral line. The new species is also distinguished from M. hypsauchen by having 56-65 predorsal scales and 90-104 lateral line scales (vs . 36-54, and 65-82, respectively). A detailed osteological description of the new species is provided.
