A New Species

A new species of the tetraodontid fish genus Canthigaster was discovered during a recent expedition to theGambier Archipelago, French Polynesia. The new species, named Canthigaster criobe herein, is the only knownspecies of Canthigaster having 12–14 brown stripes along the body (stripes beginning in front of the eye,extending along the body, and abruptly ending at the base of the caudal fin). It also has 17 pectoral rays, the originof the anal fin inserts posterior to a vertical from the rear base of the dorsal fin and lacks spots on the caudal fin.Canthigaster criobe is currently known from a single specimen collected at the Gambier Archipelago. It appearsto be most similar to the white-spotted C. janthinoptera, a wide-ranging, Indo-Pacific species, which also inhabitsthe Gambier Archipelago, and to the Hawaiian endemic C. jactator forming a species complex that exhibitsincomplete lineage sorting. Specimens of C. axiologus, or an undescribed but very similar sibling species, werealso collected at the Gambier Archipelago. Molecular analysis of these samples reveals an affiliation with C.axiologus specimens collected from disjunct localities in the western Central Pacific. Canthigaster axiologus wasnot previously known to occur east of the Tonga Islands. Geographic range expansions are also reported for C. rapaensis and C. amboinensis.

A new species of jawfish, Opistognathus ocellicaudatus, is described based on a single specimen collected at 67 m depth in Sagami Bay (near the mouth of Tokyo Bay), Honshu Island, Japan. The new species can be separated from all other Indo-West Pacific jawfish species in having 3 longitudinal dark brown stripes on the body, a large dark whitish-rimmed ocellus on the caudal fin, a small black blotch on the opercular flap, the dorsal fin with 11 spines and 11 soft rays, the anal fin with 2 spines and 11 soft rays, 21 pectoral-fin soft rays, 26 vertebrae, 42 oblique scale rows, and 2 supraneurals. The holotype is a female containing mature eggs, suggesting summer spawning. The type locality was close to the northern distributional limit of Opistognathidae in the Indo-West Pacific.

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 small-sized scorpionfish, Scorpaena bulacephala, is described on the basis of seven specimens collected from off Norfolk and Lord Howe Islands, northern Tasman Sea, southwestern Pacific Ocean, at depths of 86–113 m. The new species is closely related to a Hawaiian endemic species, S. colorata. The two species are distinguished from other Indo–Pacific species of Scorpaena by the following combination of characters: exposed cycloid scales covering the anteroventral surface of the body and pectoral-fin base, the lateral surface of the lacrimal without spines, and 17 pectoral-fin rays. The new species differs from S. colorata in having 39–44 longitudinal scales rows and relatively short fin spines and rays, especially short longest pectoral-fin ray (31.5–33.5% of standard length). Morphological changes with growth and sexual dimorphism of the new species are also discussed.

Introduction: The genus Massinium includes 11 species, most from the Indo Pacific Ocean, and had not previously being reported from the American continent. Objective: To present the new record of the genus Massinium and describe a new species of this genus. Methods: Material collection was done by SCUBA-diving to depths of a maximum of 9 m. Results: Massinium ocumichoensis sp. nov. is described from seven specimens that extends the range of the genus to the American continent (Guerrero, Michoacan and Jalisco, Mexico). The new species lives in sandy-rocky substrata, from 2 to 16 m deep. It is distinguished from its congeneric species by a combination of morphological characters: mid-dorsal slightly bigger pseudobuttons (40-60 μm), and tables in the body wall. A taxonomic key for distinguishing the species of Massinium is provided. Conclusions: The geographic range of the genus Massinium is extended to the Mexican Pacific with M. ocumichoensis sp. nov.

A New Species

A new species of the hermit crab genus Paguristes, sensu stricto, Paguristes alcock n. sp., is described and illustrated from materials collected in Australia, Indonesia and the Philippine Islands. It is proposed that this taxon, or a species identified simply as Paguristes sp. by Lewinsohn (1969) in his monograph of Red Sea Anomura, may be conspecific with the species incorrectly referred by Alcock (1905) and several subsequent carcinologists to Paguristes ciliatus Heller, 1862. Lewinsohn subsequently re-identified his material of Paguristes sp. as Paguristes ciliatus sensu Alcock, 1905 and P. pusillus Henderson, 1896. Alcock’s single specimen of P. ? ciliatus from the Persian Gulf was not available for reexamination. Lewinsohn’s specimens however, have been reviewed and compared with the present authors Indo-Pacific species and with a specimen identified by Henderson as P. pusillus. Lewinsohn’s Red Sea specimens are described and illustrated herein as P. lewinsohni n. sp., as are the specimens identified as P. pusillus by Thompson (1943) from the John Murray Expedition. An illustrated description of P. pusillus is also provided to facilitate recognition of these superficially similar species. Paguristes pusillus zhejiangensis Wang & Tung, 1982 is considered to be a distinct taxon, not a subspecies of P. pusillus, and is herein elevated to full specific rank.

Heteroclinus argyrospilos, n. sp. is described as a new species from specimens sampled by sled and dredge in 55–100 m off South Australia and Western Australia. The species has a strongly compressed body and spatulate orbital tentacle similar to some shallow water species, particularly those of the Heteroclinus heptaeolus complex, which is characterized by having three segmented dorsal-fin rays, with the last two rays widely separate from the first ray. It is distinct from other Australian clinids in having two segmented dorsal-fin rays, well separated from the last dorsal-fin spine and a reduced lateral line on the body. It is known from a greater depth than other members of the genus.

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 of Cetopsis is described from Guiana Shield drainages in Guyana and Suriname. The new species is found in the Konawaruk River and tributaries, Essequibo River basin, Guyana, and in the Mauritie Creek, tributary to the Tempati River, upper Commewijne River basin, Suriname. The new taxon can be distinguished from all congeners by a combination of features: dark spots on sides of the body eye-sized or larger, dark, bilobed patch at the base of the caudal fin, absence of a dark humeral spot, absence of dark pigmentation along the fin-membrane posterior to the first dorsal-fin ray, dark pigmentation at the base of the dorsal fin, dark spots extending ventrally to the bases of anal-fin rays, and 41 total vertebrae with 28 caudal vertebrae. Data on internal anatomy of the new species were incorporated into a previously-published phylogenetic analysis and resolves the position of the new species as the sister group of C. motatanensis, from Lago Maracaibo basin. The new Cetopsis is the first species of the genus known to occur exclusively in the Guiana Shield.
