Abstract Aim The objective of this work is to record the occurrence of Apistogrammoides pucallpaensis in Brazilian territory, since so far its distribution is restricted to Peru and Colombia. Methods The collections were carried out in the year of 2013, during the research of ichthyofauna of the region of Auati-Paraná, located in the Mamirauá Reserve in the state of Amazonas. In the floating aquatic vegetation was used net and on the coastal region rapichés. Apistogrammoides is the only one among Geophaginae that has 6-9 spines in the anal fin, while Apistogramma has 3-4. Results Note the presence of three evident mark on the caudal fin and presence of a black stripe on the side of the body that follows from the eye to the caudal peduncle feature thet differentiate the genre. Conclusions This work extends the distribution of A. pucallpaensis being the first record of the species for Brazil.

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.

A New Species

Hemiodus jatuarana, a new species of the Hemiodontidae from Oriximin , rio Trombetas, Amazon Basin, Brazil, is described. The new species can be readily distinguished from its congeners by the presence of a horizontally elongated dark spot on the caudal peduncle, and by the absence of any other dark pigmentation pattern on the body. Hemiodus jatuarana is readily separated from H. immaculatus, another species without dark pigmentation on the body, by having 25 27 epibranchial and 36 37 ceratobranchial gill rakers on the first branchial arch, and caudal-fin lobes without longitudinal stripes, vs. 14 16 and 21 25 gill rakers, and a conspicuous longitudinal stripe on each caudal-fin lobe in H. immaculatus. The new species is only known from its type-locality, where it cooccurs with H. immaculatus.

One of the most gorgeous colored and endangered Hyphessobryconspecies, H. flammeus Myers, is redescribed. Diagnostic characters of the species are two vertically elongated humeral spots, no caudal peduncle blotch, 5-8 maxillary teeth, caudal fin hyaline, and longitudinal dark stripe of the body absent. Sexual dimorphism is present, with males being more colored than females and having bony hooks in the anal and pelvic fins, which are dark in their terminal portions. Comments about its occurrence in the upper rio Tietê drainage (upper rio Paraná basin), its conservation status, and the phylogenetic position into Characidae context are also presented.

Pelvicachromis rubrolabiatus and P. signatus are described from Guinea. They differ from other members of Pelvicachromis, except P. humilis, in having two contiguous tubular infraorbital ossicles instead of three with a gap between the 2 nd and 3 rd and in displaying a color pattern of seven to eight dark vertical bars during certain behavioral situations. Pelvicachromis rubrolabiatus differs from P. humilis and P. signatus in having seven instead of eight vertical bars on the body and from P. signatus in having a lesser preorbital depth. Pelvicachromis signatus differs from P. humilis in the presence of characteristic black markings in the dorsal and caudal fin of males, a black spot on the caudal peduncle of females and occasionally one or two black spots in the female s dorsal fin.

ABSTRACT A new species of Moenkhausia is described from the upper rio Machado at Chapada dos Parecis, rio Madeira basin, Rondônia State, Brazil. Among congeners, the new species is similar to Moenkhausia chlorophthalma, M. cotinho , M. lineomaculata , M. plumbea, and M. petymbuaba by having dark blotches on the anterior portion of the body scales, which are absent in the remaining species of the genus. The new speciesdiffers from aforementioned species by possessing blue eyes in life, 15-18 branched anal-fin rays, and a well-defined, round caudal-peduncle spot that does not reach the upper and lower margins of the caudal peduncle and does not extend to the tip of the middle caudal-fin rays.

Brocchinia verheckeni n. sp. and Brocchinia harasewychi n. sp. are described from several stations from 340 to 720m on the Continental Slope off Northeast Brazil. Brocchinia verheckeni occurred from the states of Ceará to Sergipe, and B. harasewychi was collected from the states of Pernambuco to Alagoas. Both species are considered endemic to these regions. This is the second record of the genus Brocchinia Jousseaume, 1887 in deep waters off Brazil. Brocchinia harasewychi has a protoconch with 1 ¼ whorls, which is more inflated in comparison to B. verheckeni, the body whorl has 3 spiral cords, the uppermost bordering the suture and the other 2 near mid-whorl. The body whorl of Brocchinia verheckeni has 3 strongly nodulose spiral cords and an outer lip with 5 to 6 internal denticles, while that of B. harasewychi has a smooth outer lip. The genus Gergovia Cossmann, 1899 is recorded for the first time in the Atlantic Ocean with the description of Gergovia petiti n. sp., known only from the oceanic region from Northeast Brazil, occurring from the state of Ceará to the state of Bahia, as well as in the Fernando de Noronha archipelago, probably living in the muddy substrate at depths of between 206 and 720 meters.

A New Species

A new species of Gephyrocharax is described from the río Cascajales basin, a tributary of the río La Colorada, río Magdalena system, Colombia. The new species is distinguished from its congeners, exceptG. melanocheir, by the absence of an adipose fin in most specimens and by the possession of a lateral branched pectoral-fin ray in males with a distal fan-shaped structure with minute bony hooks and a dark blotch or a few scattered dark brown chromatophores along its branches. The new species differs from G.melanocheir by the absence of an intense black pigmentation at the base of the anterior five dorsal-fin rays, the number of vertebrae (40-41vs. 38-39), the frontals contacting each other anterior to the epiphyseal bar in adults (vs. the absence of contact), the posterior margin of the mesethmoid straight in its central portion (vs. strongly concave at this point), the pouch scale of mature males reaching caudal-fin ray 11 or the area between caudal-fin rays 11 and 12 (vs. reaching only to caudal-fin ray 10 or the area between caudal-fin rays 9 and 10), the number of minute terminal branches of the lateral branched pectoral-fin ray of mature males (60-88 vs. 28-54), a longer black lateral stripe along the body in males (reaching to the base of the caudal-fin rays vs. reaching the middle of the length of the caudal peduncle), and the snout length (28.3-31.8% HLvs. 22.2-28.0% HL). The diagnosis ofGephyrocharax is modified to include species with the adipose fin variably present

Three new species of Hyphessobrycon (Characiformes: Characidae) are described from the upper rio Araguaia basin. Hyphessobrycon langeanii n. sp. is distinguished from all congeners by the presence of a well-defined, round humeral spot, a reticulate color pattern, a broad, horizontally-elongate caudal-peduncle blotch, and a relatively wide, faint midlateral dark stripe. Hyphessobrycon eilyos n. sp. is distinguished from all congeners by the absence of humeral and caudal spots; by the presence of numerous dark chromatophores on the lateral surface of the body, intensely concentrated on the ventral region from the pelvic-fin origin to the end of the caudal-fin base, dorsal, adipose, and caudal fins with carmine red pigmentation in life; and the presence of 7-11 maxillary teeth. Hyphessobrycon weitzmanorum n. sp. is distinguished from all congeners by the combination of the possession of two humeral spots and a general dark color pattern. These three new species, along with Creagrutus molinus (Characidae), Apareiodon tigrinus (Parodontidae), Aspidoras velites (Callichthyidae), an undescribed member of the Hypoptopomatinae (Loricariidae), Cnesterodon septentrionalis (Poeciliidae), and Simpsonichthys cholopteryx (Rivulidae), all of which are apparently endemic of the upper rio Araguaia, indicate that this area is a previously unrecognized area of endemism.
