A New Species

Cottunculus tubulosus n.sp. is described from one specimen caught in the summer of 2004 in the Northeast Atlantic, at about 2000 m depth in the Mid Atlantic Ridge. The species is characterised by a slender body, a long head, large pointed cranial spines, large bony tubules along the lateral line, prominent dermal prickles along the back, dorsal and anal fins set far posterior, a short caudal peduncle, and no banded colour patterns. From morphological characters, the species seems closely related to the South African species C. spinosus.

A new species of Limonium from Namaqualand coast, South Africa is here described and named L. dagmarae. Shared morphological characters with related South African species place the new species within L. sect. Circinaria. Evidence is presented to segregate the new species from relatives based on discrete morphological and environmental characters. The holotype of the L. dagmarae is preserved at NBG.

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.

Characidium tapuia, a new species apparently endemic to the rio Parnaíba basin, Brazil, is described. The new species is easily distinguished from congeners, except C. lanei, C. nana, and C. samurai, by having a broad and conspicuous dark lateral stripe, extending from the tip of snout to the end of caudal peduncle and by the absence of dark vertical bars on body of specimens larger than 23.0 mm SL. Characidium tapuia differs from the aforementioned species by a series of features, including 12 circumpeduncular scales (vs. 13 or 14 in C. lanei and C. samurai), presence of parietal branch of the supraorbital canal (vs. absence in C. lanei and C. nana), complete lateral line and adipose fin present (vs. lateral line incomplete and adipose fin absent in C. nana), and midlateral stripe with irregular borders (vs. lateral stripe with overall straight borders in C. samurai).

Nandus prolixus sp. nov. is described from the Sepilok River drainage in Sabah, northeastern Borneo. This species is distinguished from its only Sundaic southeastern Asian congener, N. nebulosus, in having a longer, more produced snout (25.7–30.6% HL vs. 18.5–26.1), more lateralline scales (33–37 vs. 24–34), more scales below the lateral line (12 vs. 10–11), fewer spines in the dorsal fin (XIV vs. XV–XVI), and fewer pectoral-fin rays (15–16 vs. 17–19). It differs from N. nandus (from India) in having fewer lateral-line scales (33–37 vs. 42–55), fewer scales above the lateral line (4–5 vs. 6–7), fewer scales below the lateral line (12 vs. 14–18), more dorsal spines (XIV vs. XII–XIII), and the absence (vs. presence) of a distinct dark spot at the base of the caudal peduncle. It differs from N. oxyrhynchus (from mainland southeastern Asia) in having a more slender body (body depth 37.6–40.5% SL vs. 41.3–44.1) and a less steeply sloping predorsal profile.

A new South African species of the genus Chaperiopsis is described from material deposited in the Muséum National d'Histoire Naturelle, Paris. Chaperiopsis stephensoni is redescribed and figured from the original material.The genus Chaperiopsis Uttley, 1949 is widely distributed in the southern hemisphere. Numerous species of this genus have been described in different works; notable amongst these are the works of Busk (1854, 1884), Kluge (1914), Uttley (1949), Gordon (1984), Hayward & Thorpe (1988), Reverter Gil & Fernández Pulpeiro (1995) and Hayward (1995). Some previous records of Chaperiopsis spp. from South Africa are included in the works of Jullien (1881), Busk (1884), O'Donoghue & De Watteville (1935), O'Donoghue (1957) and Hayward & Cook (1983).

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

A new species of Microschemobrycon with a restricted distribution was recently discovered in the Rio Curuá, Rio Xingu basin, Pará, Brazil. Microschemobrycon cryptogrammus new species can be promptly distinguished from all congeners by the presence of a rounded, dark, conspicuous caudal-peduncle blotch and by a subjacent dark midlateral stripe visible in life. Additionally, the new species can be distinguished from all its congeners, except M. elongatus, by the presence of a longitudinal dark stripe along the lower jaw. The new species can be distinguished from M. elongatus by presenting lateral line with 36–38 pored scales, anterior and posterior nostrils coalescend, dark chromatophores concentrated along the ventral margin of the caudal peduncle and by the presence in life of a dark spot at the base of the dorsal-fin origin.

A New Species

A new species of Leporinus is described from the rio Teles Pires, rio Tapajós basin, Amazon basin, Brazil. The new species is diagnosed based on dental formula 3/4, a dark midlateral stripe on body and a series of transversal dark bars on the dorsum. The new species is similar to a handful of congeners based on the color pattern, including L. britski, L. microphysus, L. parvulus, and L. vanzoi, all of which also occur at the rio Tapajós basin. The new species is distinguished from the aforementioned congeners based on number of premaxillary teeth, number of scales in lateral line and/or around caudal peduncle. The new species is apparently endemic to the rio Teles Pires near the Sete Quedas rapids and upstream.

Predorsal Distance

Microglanis robustus, new species, is the first Microglanis to be described from the Rio Tocantins basin, Pará, Brazil, and differs from the congeners by the presence of a cordiform blotch in the nape, instead of a transverse light stripe; neuromasts of the superficial lines surrounded by melanophores; robust body with short snout, head and predorsal distance; and deep caudal peduncle. The mapping of superficial neuromasts and cephalic sensory canals evidenced intra and interespecific polymorphisms and, therefore, of little value for phylogenetic analysis within the genus.
