A New Species

Chrysobrycon yoliae, new species, is described from a drainage flowing into the río Yucamia basin, río Ucayali basin, Peru. Chrysobrycon yoliaeis readily distinguished from its congeners by the anterior tip of pelvic bone situated anterior to the fifth rib (vs. situated posterior to the fifth rib), the presence of 20-26 dentary teeth (vs. 11-19), and the possession of a terminal lateral-line tube between caudal-fin rays 10 and 11 (vs. the absence of this tube, except in C. eliasi). The new species differs from C. eliasiand C. myersiby the presence of teeth on third pharyngobranchial (vs. the absence of teeth on this bone) and also differs from C. eliasiby the dorsal-fin origin situated at vertical through anal-fin rays 5 to 7 (vs. located at vertical through anal-fin rays 8 to 10), the posterior extent of the ventral process of quadrate reaching the vertical through posterior margin of symplectic (vs. not reaching the vertical through posterior margin of symplectic), the dorsal-fin to adipose-fin length 26.8-28.8% SL (vs. 23.9-26.8% SL), and the body depth at dorsal-fin origin 34.4-42.2% SL (vs. 24.1-34.5% SL).

Gobiesox lanceolatus is described from a single specimen collected from 300 meters depth in the Los Frailes submarine canyon in the southwestern Gulf of California. The "Canyon Clingfish" is unique within Gobiesox in having a lanceolate caudal fin, with the central rays longer than those above and below them. It is also distinguished by 14 dorsal-fin rays (first tiny and unsegmented), 11 anal-fin rays, 28 pectoral-fin rays, anus slightly closer to anal-fin origin than to posterior margin of pelvic disc, and dorsal-fin origin in front of vertical from anus. It is most similar to Gobiesox eugrammus, known from Isla Guadelupe, the coast of outer Baja California and southern California. This is the deepest record for a species of Gobiesox and only four other species of clingfishes are known from greater depths.

A new species of deepwater gurnard, Pterygotrigla (Otohime) madagascarensis sp. nov. is described, based on two specimens collected on the upper continental slope south of Madagascar, in the southwestern Indian Ocean. The new species belongs to the tropical Indo-Pacific subgenus Otohime in having a short rostral projection, short posttemporal spine, long opercular spine and no cleithral spine. It is most similar to P. (O.) multipunctata, and P. (O.) urashimai, in having no large blotch on the first dorsal fin, a jet-black blotch and no white ocellus on the inner pectoral-fin surface, with no scales on the breast and front of the pectoral-fin base. However, the new species differs from the latter two species by the combination of the following characters: first dorsal-fin spines 7, second dorsal-fin rays 12, dusky rays on the inner pectoral-fin surface, one row of blackish botches on second dorsal fin, and no papillae on the dorsal surface of oral cavity. A key is provided for the twelve Pterygotrigla species now in the subgenus Otohime.

A new species of riffle minnow, Alburnoides holciki (Cyprinidae), is described from northwestern Afghanistan andnortheastern Iran. It is distinguished from related species by a combination of characters including a well-defined, sharp,scaleless or only slightly scaled ventral keel; a short, slightly pointed snout; a terminal mouth with the tip of the mouthcleft, on a level with the upper half of the pupil; a large eye (orbit width about equal to interorbital width); (46)47–51(55)lateralline scales to posterior margin of hypurals; 2.5–4.2 pharyngeal teeth; usually 8½ branched dorsal-fin rays; usually13–16½ branched anal-fin rays; 40–42, usually 41, total vertebrae; caudal vertebral region longer than abdominal region(most frequent vertebral formulae 20+21, 20+22 and 19+21); and usually 13 or 14 predorsal vertebrae. A comparison withAlburnoides species from rivers of the South Caspian Sea, the northern slope of the Kopetdag Mountains and the Amu Darya basin is provided.

Moray Eel

Gymnothorax hansi, a new species of moray eel, is described from three specimens caught in ~ 146 m at Grand Comoro (Ngazidja) Island in the Comoros Islands. The length of the head plus the body is distinctly longer than tail; the dorsal fin origin is at a vertical midway between the gill opening and the rear edge of the eye. The head length is 11 to 12% total length. The colour is chestnut brown dorsally on the head, body and most of the tail; the dorsal and anal fins are brown anteriorly, blackish posteriorly with a bright white margin from dorsal fin origin round the tail tip to the anal fin origin; anterior nostril tube, posterior nostril mound and iris are yellow; head and ventrolateral part of body of 101 cm adult male golden brown, with several, irregular, distinct, dusky or black spots scattered over most of the body, tail and dorsal fin; head of 101 cm adult female brown dorsally, paler below; female with a few faint dusky spots on body and tail; both sexes with pores on jaws set in white spots. Teeth small, sharp, caniniform, slightly curved, uniserial on maxillae and dentaries; longest intermaxillary tooth equals 64% eye diameter; vomer with 3 minute teeth. The vertebral counts are higher than in most morays: 4 predorsal, 82 84 preanal and 183 185 total.

A New Species

Scolopsis meridiana n. sp., described from 30 specimens collected from northern Australia, is closely related to S. taenioptera, both species having a dorsal scaled area on the head extending anteriorly to between the anterior margin of the eye and anterior nostril, the upper part of the pectoral-fin base with a reddish blotch when fresh, and lacking a small antrorse spine below the eye. However, the new species is distinguished from the latter by having two bands across the snout dorsum (vs. one band in S. taenioptera), 18–20 diagonal lines on the lateral body surface below the lateral line (diagonal lines absent), the posterior nostril horizontally elongated (vertically elongated), a deep caudal-peduncle and short pre-dorsal-fin length. Scolopsis meridiana is distributed in northern Australia, whereas S. taenioptera occurs in Southeast Asia. Two geographic populations of S. taenioptera (Philippines and remaining Southeast Asian region) are recognized following morphological and genetic analyses.

Abstract Chelon caeruleum sp. nov. is described as a new species of Chelon encountered in the Rashid coastal region of the Mediterranean Sea, Egypt. With this finding, the new species is the sixth member of the genus Chelon. Chelon caeruleum sp. nov. is distinguished from its congeners by the following characters: colouration of body is dark bluish grey dorsally and the sides are blue; head length 20.5 to 21.6% SL; head width 13 to 13.5% SL; pre-first dorsal fin length 50% SL; eye diameter 4.6 to 5.2% SL; postorbital length 10.7 to 11.1% SL; unbranched pyloric caeca are 2 short and 4 long; a pair of long (one longer than the other), spine-like neural postzygapophyse on the second vertebra. DNA of Chelon caeruleum sp. nov. and five mullet species (Mugil cephalus, Liza carinata, Liza ramada, Liza aurata, and Chelon labrosus) was extracted then amplified using polymerase chain reaction (PCR) and sequenced. The mtDNA cytochrome oxidase subunit I sequence analysis confirmed that Chelon caeruleum sp. nov. is distinct from other congeners of Chelon and it is a different species of Chelon which is new to science.
