A New Species

Anthias hutomoi, a member of the family Serranidae (subfamily Anthiinae) is described from 11 specimens taken by trawl at Seram, Indonesia. It appears to be allied to Anthias cichlops (BLEEKER,), but differs in several important respects, including head length, caudal shape, and counts for the lateral-line, soft dorsal rays, and pectoral  rays.

A New Species

Characidium samurai, a species of the family Crenuchidae apparently endemic to rio das Almas and rio Vermelho basins, Bahia, Brazil, is described. The new species is readily distinguishable from its congeners, except C. lanei, by having a dark lateral band along the head and body that is particularly broad from the rear of the head to the end of the caudal peduncle (1.5 or 2 scales wide) and by the absence of dark bars or blotches on the ventral half of the body. Characidium samurai differs from C. laneiby having the lateral band with straight borders overall (vs.lateral band with somewhat irregular borders due to blotches extending dorsally or ventrally), anal fin ii,7-8 (vs. ii,6), and 4 horizontal scale rows above the lateral line and 4 below (vs. 5/3). It further differs from congeners by a series of features, including isthmus completely covered by scales, lateral line complete with 34-37 perforated scales, 9 scales on the transversal line, 14 scale rows around the caudal peduncle, anal fin ii,7-8, and the absence of dark bars or spots on the fins, except by a faded dorsal-fin bar. The presence of pseudotympanum in four species of Characidium is discussed.

A New Species

Bangana brevirostris, new species, is described from the Lancang-Jiang in Yunnan, Southwest China. It can be distinguished from all other congeners by the following combination of characters: a pair of minute rostral barbels; mental groove short and shallow; dorsal fin with 12–13 branched rays; 42–44 lateral line scales; eye large, its diameter 28.1–32.9 % of head length; snout short, its length 25.5–32.7 % of head length. It shares the same postlabial groove-type with Bangana dero and B. devdevi, which makes them very different from other congeners.

A New Species

ABSTRACT A new species of Leporinus is described using morphological data and compared to all other species of the family. Specimens were illustrated using digital photograph, measured using digital calipers, and had teeth, scales, and fin rays counted under a stereomicroscope. The new species is distinguished from all other Anostomidae, except Anostomus anostomus, A. brevior, A. ternetzi, Hypomasticus despaxi, Leporinus arcus, and L. striatus, by having four dark longitudinal stripes on body. The new species is distinguished from aforementioned species by having terminal mouth with four teeth on the premaxilla, 12 series of scales around caudal peduncle, and 34 to 36 scales in the lateral line. The new species is remarkably similar to Leporinus arcus, which occurs on the opposite side of Guyana Shield highlands. The new species and L. arcus are possibly closely related to Leporinus gomesi, L. granti, L. lebaili, L. melanostictus, L. nijsseni, and L. santosi.

A new species of chimaeroid, Hyd rolagus mccosker i sp. nov., is described from the Galápag os Islands. This species represents the second member of the family Chimaeridae known from the eastern equatorial Pacific. It can b e distinguis hed from its congeners by a combination of the following characters: small head with short, blunt snout; preopercu lar and oral lateral line canals branching from the same node off the infraorbital canal and sharing a short common b ranch; dorsum medium brown with numerous narrow, shar ply delineated circular and elongate white blotches; ventrum white to tan with extremely fine brown mottl ing. The species is compared to Hyd rolagus n ovaezealandiae and Hyd rolagus colliei , the most similar congeners in color pattern and morphology.

Symphysanodon xanthopterygion, new species, reported herein from 15 specimens collected near Quilon, India, off the Kerala Coast in the southeastern Arabian Sea, becomes the twelfth described species in the genus. The following characters in combination distinguish S. xanthopterygion from its congeners: parapophyses present on first caudal vertebra, total number of gillrakers on first arch 38 to 42, tubed lateral-line scales 54 to 59, sum of lateral-line scales plus total number of gillrakers in individual specimens 94 to 101, head length 33 to 37% SL, head depth 18 to 21% SL, snout length 5 to 6% SL, body depth 24 to 27% SL, lower caudal-fin lobe bright yellow.

A new species of Metynnis is described from the rio Cuiabá and rio Manso drainages, in the upper rio Paraguay basin, Mato Grosso State, Brazil. This laterally compressed species, which rarely exceeds 140 mm in SL, is readily distinguished from other members of the genus Metynnis by having 100-110 lateral-line scales, 48-56 rows of scales above the lateral line, 32-36 circumpeduncular scales, 22-24 gill rakers, 38 vertebrae, singular color pattern, and relatively smaller snout, width, and head length.

ABSTRACT A new species of Astyanax is described from the arheic system of Río Sucuma, in Catamarca, Northwestern Argentina. The new species is distinguished from its congeners by a combination of characters including the presence of a broad vertical humeral spot, absence of maxillary teeth, and absence of circuli in posterior field of scales. Furthermore, this species is distinguished by the orbital diameter, head length, branched anal-fin rays, perforated lateral-line scales, transverse scales, dentary teeth with abrupt decrease in size. This species is, to date, the single known fish endemic of Río Sucuma basin.

Ctenobrycon oliverai, new species, is described from the río Orinoco drainage and its main tributary, río Apure, Venezuela. This species is readily distinguished from its congeners by the high number of series of scales above lateral line and by morphometric differences in body depth, head length, and interorbital distance. Statistical multivariate analysis was also conducted in order to test hypothesized differences among species of Ctenobrycon. A brief discussion on the taxonomy of this genus is provided.
