A New Species

A new species of amphipod from the genus Metopelloides Gurjanova, 1938 (Crustacea: Amphipoda: Stenothoidae) asso-ciated with two species of sublittoral hermit crab species, Pagurus pectinatus (Stimpson, 1858) and Elassochirus cavi-manus (Miers, 1879) (Crustacea: Decapoda: Paguridae), is described from the Russian coasts of the Sea of Japan. The newspecies clearly differs from the congeners by the combination of morphological features such as telson without lateralspines, an elongated mandibular palp with single apical setae, the structures of distoventral palmar margins of subchelaon gnathopods I and II in females, bright white-red body coloration. Thus, the record of Metopelloides paguri sp. nov.represents the second record of the family Stenothoidae in the association with sublittoral hermit crabs from the Sea of Japan.

A New Species

Discovery of a new hermit crab species from the Ryukyu Islands, Japan, led us to reexamine the holotype and supplemental specimens of Trichopagurus trichophthalmus (Forest), the type species of the heretofore monotypic Trichopagurus de Saint Laurent. Our examination has revealed that the gill lamellae of T. trichophthalmus are actually entire (= biserial), rather than shallowly divided distally (= quadriserial) as reported by de Saint Laurent (1970). The new species is assigned to Trichopagurus because of the 11 pairs of biserial gills, well-developed rostrum, moderately long male right sexual tube directed toward exterior, and the possession of a single left gonopore in female. The new species, T. macrochela n. sp., is distinguished from T. trichophthalmus primarily by the dorsoventrally flattened carpus with a distinctly delimited dorsomesial margin, less setose ambulatory legs, and markedly asymmetrical coxae of the female fifth pereopods, of which the left bears numerous setae on the ventral surface. It has been also shown that previous records of T. trichophthalmus from the Palau and Yap Islands are based on both true T. trichophthalmus and T. macrochela. A comparative, updated redescription of T. trichophthalmus is also provided.

A New Species

A new species of the pagurid hermit crab genus Catapagurus A. Milne-Edwards, 1880, C. insolitus, is described and illustrated based on specimens from shallow waters in Okinawa Island, the Ryukyus. It belongs to an informal species group characterized by the possession of blade-shaped ambulatory dactyli, and is morphologically most similar to C. kosugei (Asakura, 2001). However, the new species is unique within the genus in having a multispinose antennal acicle, rarely seen in species of the family Paguridae.

A New Species

A new hermit crab species of the pagurid genus Pagurixus Melin, P. fasciatus, is described from shallow rocky reefs of Japan. Fifteen congeners are known from the Indo-Pacific region. The new species is most similar to P. handrecki Gunn & Morgan, known from Western and southeastern Australia, but can be distinguished from the latter by the less setose antennal acicle, the dorsomesial margin of the right palm which is sharply carinate along the entire length, the fewer ventral spines on the ambulatory dactyli, and the sharp, smooth dorsolateral carina of the female right palm. Coloration in life is also different between the two species.

A New Species

A new species of Paguridae, Pagurus ikedai, from the Tokyo Submarine Canyon and vicinity, Japan, is described and fully illustrated, including information on live coloration. This new species is distinguished primarily by size and shape of the chelipeds, in particular the massiveness of the left, and the presence in some males of a papilla or very short sexual tube on the right coxa of the fifth pereopod and a papilla on the coxa of the left. It is assigned to the bernhardus group which now includes eight species.

A New Species

A new species of the hermit crab genus Diogenes Dana, 1851, D. spongicola, is described and illustrated on the basis of material collected from two locations off southern India. It appears close to D. takedai Rahayu, 2012 among about 70 congeners, but easily differentiated from the latter by the spinulose anterolateral margins of the shield, the article 2 of the antennal peduncle armed only with one distal spine, the longer, spinose antennal acicle, the absence of prominent spines on the ventrolateral margin of the cheliped meri, and the different color of the cheliped palm. Specimens of the new species were all collected from cavities of a callyspongiid sponge Callyspongia diffusa (Ridley, 1884), suggesting a possible association between the hermit crab and sponge.

A New Species

A new species of the hermit crab genus Diogenes Dana, 1851 (Diogenidae), D. canaliculatus, is described and illustrated on the basis of material from off the Kerala State, southern India. It is referred to the D. edwardsii (De Haan, 1849) species group, and compared with D. bicristimanus Alcock, 1905, D. fasciatus Rahayu & Forest, 1995, D. laevicarpus Rahayu, 1996 and D. moosai Rahayu & Forest, 1995. The characteristically sculptured left chela and the unarmed dorsal margins of the propodi of the second and third pereopods distinguish the new species from these congeners.

A New Species

A new species of the pagurid hermit crab genus Turleania McLaughlin, 1997, T. rubriguttatus, is described on the basis of two specimens, including one male and one female, from shallow subtidal waters in Kochi Prefecture, Japan. The new species appears close to T. albatrossae (McLaughlin & Haig, 1996), known from the Philippines, but the proximally unarmed dorsal surface of the right chela palm and the lack of a dorsomesial row of spines on the left cheliped carpus easily distinguish T. rubriguttatus n. sp. from T. albatrossae. Examination of the type material of T. similis Komai, 1999 and T. spinimanus Komai, 1999, and supplemental material from Japan, confirms that the two taxa are synonymous with T. senticosa (McLaughlin & Haig, 1996), as was suggested by previous authors. Re-examination clarified that in T. senticosa the maxilliped 3 has no developed arthrobranchs, and this led the author to assess the status of T. sinensis Han, Sha & An, 2016, which is also synonymised with T. senticosa.
