Cabdio crassus, a new fish species, is described from the Kaladan River in Mizoram, India. The new species is distinguished from all its congeners by having a ventral keel extending from the middle of the chest, between the posterior base of the pectoral fin and along the abdomen up to the anus (vs. more or less keeled median scales from mid-point of abdomen between posterior base of pelvic fin up to anus in all other Cabdio) and 11½–12½ branched anal-fin rays (vs. 7 in C. jaya and 9 in both C. morar and C. ukhrulensis). It is further distinguished from C. morar and C. ukhrulensis by possessing more lateral-line scales (45–51 vs. 38–42 in C. morar and 35–37 in C. ukhrulensis), more predorsal scales (20–23 vs. 17–18 in C. morar and 14 in C. ukhrulensis) and more lateral transverse scales (½7/1/3½ vs. 5/1/2 in both C. morar and C. ukhrulensis). It also differs from C. jaya in having fewer lateral-line scales (45–51 vs. 52–60), more lateral transverse scales (½7/1/3½ vs. 5/1/3) and more pharyngeal tooth-rows (3 vs. 2). Furthermore, the cytochrome c oxidase sub unit I (coi) gene sequence separates Cabdio crassus from all other Cabdio species (interspecies distance ranges from 7.8–12.3%). The anomalies observed among the GenBank sequences of the genus Cabdio are discussed and resolved.

New Fish Species

A new fish species from the South China Sea, Pegasus nanhaiensis sp. nov., is described herein. The new species is readily distinguished from all other species of the genus Pegasus with the following characteristics: A rounded hump-like tubercle on each of dorsal plates I, II, and III. Noticeable hexagonal patterns on the dorsal carapace with a clear boundary, and two paired caudolateral plates overlapping the junctions between tail rings II and III, and between tail rings IV and V. The integrated evidence from both morphological and genetic studies indicates that P. nanhaiensis represents an independent lineage within the genus Pegasus.

A new species of the genus Garra is described from the Ranga River of the Brahmaputra basin, Arunachal Pradesh, northeastern India. Garra magnacavus, new species, differs from its congeners in having an incipient proboscis with a transverse lobe, 15−19 rounded large pits on the snout, weakly developed non-fleshy central callous pad, and an elongate body with 42 lateral-line and 14−16 predorsal scales.

Bryconops collettei and B. magoi  are described from the Caura and Miamo (Bolívar State), Iguapo (Amazonas State) and Moquete (Anzoátegui State) rivers, Venezuela.  These new species belong to the subgenus Bryconops, based upon apomorphies of the jaws and gill rakers and are compared with members of the subgenus.  Based on morphology, meristics and color patterns, B. collettei and B. magoi are distinguished from B. caudomaculatus, the closest species in the subgenus, by having a generally more slender body, pored scales of the lateral line extending beyond the hypural plate, and a diffuse ocellus partially filled with red color only on the upper lobe of the caudal fin.  Bryconops collettei is distinguished from B. magoi on the basis of meristic and morphometric characteristics.  B. caudomaculatus has been largely misidentified in the literature and we provide comments as a guide to its proper recognition.

Schistura syngkai, a new stone loach, is described from the Twahdidoh Stream of Wahblei River (Surma-Meghna drainage) in Meghalaya, northeast India. It is unique among its Indian congeners in having a prominent dark-brown to blackish mid-lateral stripe about an eye diameter or more in width, overlain on 12–18 vertically-elongate black blotches on a golden-brown to amber body. Additionally, the species possesses an incomplete lateral line and a slightly emarginate caudal fin, and exhibits no apparent sexual dimorphism.

New Fish Species

The Great Lakes Fishery Commission has traditionally supported the conservation of genetic diversity native to the Great Lakes, and counseled caution in adding new species to the Great Lakes aquatic community. Since extinction of sub-specific taxa and establishment of new species in the Great Lakes have proven irreversible, caution and conservatism are warranted. The Commission's mandate has served the Great Lakes well in preventing, controlling, and managing exotics. For example, the Commission (1) provides a forum for interjurisdictional consultation prior to planned introduction of new fish species; (2) represents fishery agency concerns for inadvertent introductions to outside interests, as in the case of ship ballast introductions; (3) champions the conservation of genetic diversity native to the Lakes; and (4) controls the exotic sea lamprey at levels which permit fishery agencies to attain their fish community objectives.

Laubuka parafasciata, new species, is described from the Sala River of Mizoram, northeast India. The species differs markedly from all its congeners, with the exception of L. fasciata, in having a broad, dark-brown, midlateral stripe from the posterior rim of the orbit to the middle of the caudal-fin base. It is further distinguished from all other species in the genus by the combination of the following characters: premaxillae not in contact at symphysis, 16 precaudal vertebrae, minute tubercles scattered on the lower jaw, 28–33 lateral-line scales, 16–18 predorsal scales, 8½ branched dorsal-fin rays, 2½ scales between lateral line and pelvic-fin origin, and 16½–19½ branched anal-fin rays.

Black Spots

Geophagus mirabilis, new species, is endemic to the rio Aripuanã drainage upstream from Dardanelos/Andorinhas falls. The new species is distinguished from all other species of the genus by the presence of one to five large black spots arranged longitudinally along the middle of the flank, in addition to the black midlateral spot that is characteristic of species in the genus and by a pattern of iridescent spots and lines on the head in living specimens. It is further distinguished from all congeneric species, except G. camopiensisand G. crocatus, by the presence of seven (vs. eight or more) scale rows in the circumpeduncular series below the lateral line (7 in G. crocatus; 7-9 in G. camopiensis). Including the new species, five cichlids and 11 fish species in total are known only from the upper rio Aripuanã, and 15 fish species in total are known only from the rio Aripuanã drainage.

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.
