A New Species

The pontoniine shrimp genus Onycocaris Nobili, 1904 currently contains 18 species, all known from the Indo-WestPacific. In this study, a new species of the genus, O. hayamaensis, is described and illustrated on the basis of fourovigerous female and three male specimens collected from Sagami Bay, central Japan, at shallow subtidal depths of5–6 m. The specimens lived in internal cavities of an unidentified species of a haliclonid sponge, Haliclona sp. Thisnew species is referred to the O. quadratophthalma (Balss, 1921) species group, represented by four species, i.e., O.balssi Bruce, 2011, O. fujinoi Bruce, 2011, O. quadratophthalma, and O. trullata Bruce, 1978. Differentiatingcharacters between the new species and the latter four species are discussed. The present new species exhibits strongsexual dimorphism in the second pereopods and heterochaely in the male second pereopods, though these traits are notfully documented in some of other congeneric species. Diagnostic characters derived from the second pereopods should be treated carefully.

The Anthaxia (Anthaxia) midas Kiesenwetter, 1857 species-group is defined and revised. A new species from Turkey, A. (A.) cebecii sp. nov., is described and compared to its most similar species. A. midas oberthuri Schaefer, 1938 is elevated to the rank of species, and a lectotype is designated. A. (A.) spathuligera Obenberger, 1924 and A. (A.) midas muelleri Obenberger, 1925 are reconfirmed synonyms of A. midas Kiesenwetter, 1857.All species of the new species-group are illustrated, including the hitherto unknown male of A. (A.) patsyae Baiocchi, 2008, all type specimens and original data labels. In addition to diagnostic characters, informations on the distribution, biology and taxonomic position of each species are also presented, together with a short definition of the new species-group, and a key to its species.

A New Species

A new species of the rare caridean genus Bresilia Calman, 1896, B. cinctus, is described and illustrated on the basis of a single ovigerous female specimen collected from Sagami Bay, central Japan, at 218–318 m depth. The new species is morphologically most similar to B. rufioculus Komai & Yamada, 2011, known only from shallow water cave of Ie Island (depths 14–17 m), Okinawa Islands, Ryukyu Islands, but many characters, including the proportionally shorter rostrum, the well developed suborbital lobe of the carapace, and the presence of a spiniform seta on the ventral surface of the pereopod 1 palm, immediately distinguish the new species from B. rufioculus. Bresilia cinctus n. sp. is the first species of the genus known from the Japanese main islands. The discovery of the new species led us to reassess the merit of the informal division of Bresilia proposed by Komai & Yamada (2010). An identification key to the ten named species of Bresilia is presented.

A new species of diogenid hermit crab, Diogenes minimus, is described and illustrated on the basis of material from shallow subtidal waters (5–19 m) in central Japan. It appears close to D. holthuisi Asakura & Tachikawa, 2010, but easily distinguished from the latter by the shape of the antennal acicle, non-elongate male left cheliped and the armature of the right cheliped merus. Including the new species, 14 identified species of Diogenes are now known from Japanese waters. A brief overview on species of Diogenes recorded from Japanese waters is given.

A new species of the genus Odontocheila Laporte de Castelnau, 1834 is described from Venezuela as Odontocheila paraexcisipenis sp. nov. It is classified as a further species of the large O. cajennensis species-group and described subsequent to the recently published revision of the genus (Moravec (2018). Illustrations of the habitus, diagnostic characters and variability of the new species and distinguishing characters of similar species are presented in colour photographs. Revised key to species of the O. cajennensis species-group is presented with references to descriptions and illustrations of other species of the species-group in the above-cited taxonomic revision of the genus. An essential map of distribution is also given.

A new species of the upogebiid shrimp genus Gebiacantha Ngoc-Ho, 1989, G. sagamiensis, is described and illustrated on the basis of a single male specimen collected from Sagami Bay, central Japan, at depths of 101–106 m. It appears closest to G. reunionensis Ngoc-Ho, 1989, known only from La Réunion, western Indian Ocean, but the different shape of the pleomere 6 and the better developed armature of the pereopod 1 carpus distinguish the new species from G. reunionensis. Comments on the taxonomic status of Gebiacantha and Paragebicula Sakai, 2006, and on the generic assignment of the new species, are given.

A New Species

A new genus of the subfamily Pontoniinae, Ancylomenes gen. nov. is established for the ‘Periclimenes aesopius species group’ of the genus Periclimenes Costa. The new genus is distinguished from other genera of Pontoniinae on account of the strongly produced inferior orbital margin with reflected inner flange, and the basicerite of the antenna armed with an angular dorsal process. Fourteen species have been previously recognized as belonging to the ‘P. aesopius species group’. One Eastern Pacific species (P. lucasi Chace), and two Atlantic species (P. anthophilus Holthuis & EiblEibesfeldt, and P. pedersoni Chace) are now also placed in Ancylomenes gen. nov. A further new species associated with a cerianthid sea anemone, A. luteomaculatus sp. nov. is described and illustrated on the basis of specimens from the Ryukyu Islands, southern Japan, and Philippines. A key for their identification, and a checklist of the species of Ancylomenes gen. nov. are provided.

A New Species

Abstract A new species of Satanoperca is described from the Rio Araguaia, Rio Tocantins basin, Brazil, and non-native records are available in the upper Rio Paraná basin. It differs from congeneric species by color pattern characters, such as head and flank marks. It is included in the Satanoperca jurupari species group, characterized by the absence of black rounded blotches on the flank, and low meristic values. A description of the ontogeny of melanophore marks of the S. jurupari species group revealed two different types of arrangement on the flank and numerous melanophore marks on the head. A discussion on morphologically diverse assemblages in the S. jurupari species group is also provided.
