A New Species

The gobiid genus Koumansetta Whitley, placed in synonymy by some authors with the similar genus Amblygobius Bleeker, is redescribed and its validity based on an integrated morphological and molecular assessment is confirmed. The following characters have been found that distinguish Koumansetta from any of 15 recognized valid species of Amblygobius: oculoscapular transverse rows trp and tra long, extending dorsally well above level of rows x1 and x2; snout pointed, prominent, longer than eye diameter, with gently sloping dorsal profile, overhanging mouth; mouth subterminal; the upper limb of first gill arch with 1–2 slender, weak and soft gill rakers anteriorly, followed by 1–5 short, also soft, broad structures; first two dorsal-fin spines elongate, remaining spines progressively shorter; pelvic frenum absent; body brown to brown-green in upper and lateral sides with narrow yellow or orange longitudinal stripes on body and head, black ocellated spot on the second dorsal fin, and another black spot dorsoposteriorly on caudal peduncle. The following three species are assigned to Koumansetta: K. rainfordi Whitley, the type species of the genus, known from the western Pacific Ocean; K. hectori (Smith), the most widespread species, known from islands of the western Indian Ocean to Micronesia and Fiji; and a new species, restricted to the Red Sea and the inner Gulf of Aden. Koumansetta hoesei sp. nov. has formerly been confused with similar K. hectori, but differs in various details of coloration, and in some morphological characters. Moreover, K. hoesei sp. nov. is evolutionary well divergent from K. rainfordi and K. hectori, its closest relative, as shown by phylogenetic analysis of the mitochondrial COI barcoding region. In addition to the description of the new species, brief species accounts are provided for K. hectori and K. rainfordi, and a key to the three species.

Gaidropsarus mauli, new species, is described from the Lucky Strike Hydrothermal vent site (Mid-Atlantic Ridge) and from the Bay of Biscay. It is distinguished from congeners by a combination of characters such as the number of vertebrae, the size of the first dorsal-fin ray, the profile of the head and the shape of the snout, in dorsal view, the size and the position of the eyes, the length of the pelvic fins, the shape of the pectoral fins, and the length of the lateral line. A comparison with the other 13 valid species of the genus is presented.

Luciobarbus kottelati, new species, is described from the River Büyük Menderes, Aegean Sea drainage, Turkey. It is distinguished from all other species of Luciobarbus in Europe and western Anatolia by the pelvic-fin origin markedly in front of the dorsal-fin origin (vs. behind). Luciobarbus lydianus, considered to be a synonym of L. pectoralis by most recent authors is a valid species and is rediagnosed.

A New Species

Three species of the ophidiid genus Neobythites containing ocelli in the dorsal fin are known from the West Atlantic: Neobythites gilli Goode and Bean 1885, N. ocellatus Günther 1887 and N. monocellatus Nielsen 1999. In the year 2000, 18 specimens of Neobythites were caught on the upper continental slope off eastern Brazil. This is the first documented record of a Neobythites specimen off Brazil since the holotype of N. ocellatus was caught in 1873. Seventeen of the specimens are referable to N. ocellatus and one to N. monocellatus. Until now the distribution of N. ocellatus was considered to be from off Atlantic Florida, the Caribbean Sea and then a gap of 4500 km to the type locality off Brazil. However, the holotype and the 17 specimens differ from the more northerly recorded specimens in pattern and number of spots and ocelli on the dorsal fin. The 18 Brazilian specimens have two distinct ocelli, one near the origin of the dorsal fin and one above the midpoint of the fish, and further back occasionally a small, black spot, while the northern specimens occasionally have a small, black spot near the origin of the fin, a distinct ocellus above the midpoint and up to three ocelli further posteriorly. Consequently a new species, N. multiocellatus, is described based on 59 specimens from the Caribbean Sea to off Atlantic Florida. The record of the N. monocellatus specimen extends its distribution about 3000 km southwards. A comparison of the four ocellus-bearing species from the West Atlantic is made.

A new species of Astyanax from the upper rio Paraguaçu basin, Chapada Diamantina, Bahia, Brazil, is described. Astyanax sincora shares characters currently used to define the Astyanax scabripinnis species complex, as highest body depth approximately at vertical through pectoral-fin midlength and a low number of branched anal-fin rays (13–17). It differs from its congeners by a combination of characters, including eight branched dorsal-fin rays, six branched pelvic-fin rays, presence of bony hooks in pectoral and anal fins of males, dark midlateral line or stripe initiating posteriorly to the vertically elongate humeral blotch, and by the presence of 30–35 scales in the median longitudinal series. The generic positioning of the new species and some polymorphic morphological characters in Astyanax are briefly discussed. The degree of completeness of the lateral line in Hyphessobrycon balbus is discussed. [Species Zoobank registration: urn:lsid:zoobank.org:pub:D708FE7E-3FB5-4729-B438-779717F7ED1A]

The new anchovy Stolephorus babarani n. sp. is described on the basis of 26 specimens collected from Panay Island, central Philippines. The new species closely resembles Stolephorus bataviensis Hardenberg 1933 and Stolephorus baweanensis Hardenberg 1933, all these species having a long upper jaw (posterior tip extending beyond posterior margin of preopercle), and numerous dusky spots on the suborbital area (in adults), snout and lower jaw tip. However, the new species differs from S. bataviensis by usually having the posterior tip of the depressed pelvic fin not reaching to vertical through the dorsal-fin origin (vs. extending beyond vertical through dorsal-fin origin), a shorter head (23.9–25.5% of standard length vs. 25.3–28.0%), and a greater distance between the dorsal-fin origin and pectoral-fin insertion (D–P1; 133.9–151.8% of head length vs. 109.9–136.3%). Stolephorus babarani is distinguished from S. baweanensis by having a shorter snout (3.6–3.9% of standard length vs. 3.8–4.6%). Moreover, the new species can be distinguished from S. bataviensis and S. baweanensis by higher gill raker counts on the first and second gill arches (16–18 + 21–23 and 10–13 + 18–21, respectively, vs. 14–17 + 19–22 and 9–12 + 17–20 in S. bataviensis and 14–17 + 19–22 and 9–12 + 17–21 in S. baweanensis). Stolephorus babarani is separated by 5.3% and 10.7% mean p-distances in the mitochondrial COI from S. baweanensis and S. bataviensis, respectively.

Laubuka tenellais a new species characterized by the colour pattern, consisting of short dark vertical bars anteriorly on the side, and a dark lateral band posteriorly on the side, combined with a relatively short pelvic fin and 29–30 lateral-line scales. It is separated from otherLaubukaanalysed by minimum 9 % uncorrectedp-distance in the mitochondrial COI gene. The type series is composed of specimens from small streams in the Cox’s Bazar District in Bangladesh (the type locality), and the Thandwe River drainage in western Myanmar.Laubuka brahmaputraensisis strongly indicated to be a junior synonym ofL. laubuca, the second known species ofLaubukain Bangladesh.Eustira ceylonensis, currently in the synonymy ofDevario malabaricus, is a valid species ofLaubuka.

Barbus niluferensis, new species, is described from the Nilüfer River, Marmara Sea drainage, Turkey. It is distinguished by a weaker last simple dorsal-fin ray, serrated along the proximal half of its posterior margin, a maximum known size of 146 mm SL, a slender body, a short head, a short caudal fin, and larger irregular black blotches on the back and the flanks, and small black spots on the head, extending downwards to the cheeks. Barbus oligolepis Battalgil, 1941, is a valid species known from the rivers draining to the southern shore of the Marmara Sea.

A New Species

Abstract We describe a new species of gecko of the genus Pristurus from the Yemenite Red Sea Island Hanish al-Kabir. It is a small species (snout-vent length less than 30 mm) of the genus, distinguished from its congeners by a unique combination of morphological characters. Superficially, it is most similar to P. rupestris, but differs mainly by a longer and narrower snout, by its strongly compressed tail, presence of a lateral caudal groove, by a tail crest present in both sexes, by a higher number of scales bordering infralabials and a higher midbody scale count. The new species is tentatively considered to represent an island endemic. Its possible origin is briefly discussed.
