A New Species

A new species of the chirostylid squat lobster genus Uroptychodes Baba, 2004, U. fuscilineatus, is described and illustrated on the basis of a single ovigerous female from the Uraga Channel, central Japan, at depth of 250 m. The new species appears most similar to U. spinimarginatus (Henderson, 1885) and U. yapensis Dong, Gan & Li, 2021 among the 13 known congeners, but is notable in the pereopod 2 not being definitely more slender than the pereopods 3 and 4 and the remarkably spinose pereopods 1–4. A possible association of the new species with crinoid is suggested. An updated identification key to species of Uroptychodes is presented.

A New Species

A new deep-sea stalked barnacle, Ashinkailepas kermadecensis sp. nov. has been recovered from a cold-water seep at depths of 1165 metres in the vicinity of the Kermadec Ridge to the northeast of the North Island, New Zealand. There are now two species of Ashinkailepas—the other, Ashinkailepas seepiophila Yamaguchi, Newman & Hashimoto, 2004, occurs in deep, cold seeps off central Japan. As there are two species within Ashinkailepas, formal diagnoses are provided for both taxa.

A New Species

A new species of the termite genus <em>Gyatermes</em> Engel &amp; Gross (Archotermopsidae) is described and figured from a beautifully preserved forewing in late Neogene sediments of Nagano Prefecture, central Japan.  The approximately 27-mm long forewing of <em><strong>Gyatermes naganoensis</strong></em> Engel &amp; Tanaka, new species, is preserved in Late Miocene (late Messinian) mudstone of the Ogawa Formation (<em>ca</em>. 6 Ma), and is distinguished from its slightly older and larger congener <em>G. styriensis</em> Engel &amp; Gross, from the early Tortonian of Styria, Austria.  Comments are provided regarding the paleoclimatic implications of a giant termite in the Miocene fauna of Nagano.

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

Azumamiris, a new genus of mirine plant bug, is established to accommodate a new species, A. vernalis, which has occasionally been found in central Honshu, Japan. This univoltine mirine was confirmed to be associated with a gramineous dwarf bamboo, Pleioblastus chino (Fr. et Sav.) Makino, and the adults appear only in early May. The final instar nymph is also diagnosed and described. The present new genus is assumed to be allied to Stenotus Jakovlev known from the Old World and to continental Chinese Elthemidea Zheng. A key to the genera under discussion is provided.

Notes are provided for six microcaddisfly species (Trichoptera, Hydroptilidae) in the Japanese fauna. One is a new species, Hydroptila nago Ito sp. nov., described from southern Japan. The second and third, Hydroptila dorsoprocessuata Botosaneanu 1993, previously known from eastern Russia, and Hydroptila introspinata Zhou and Sun 2009, known from northeastern China and Korea, are recorded from Japan for the first time and redescribed. A fourth, Hydroptila parapiculata Yang and Xue 1994, is known from central and southeastern China and central Japan; the male is redescribed. By synonymizing Ugandatrichia shinshiroensis Ito et al. 2018, described from central Japan, with a Chinese species, Allotrichia rhynchophyllum Zhou et al. 2016, we record the genus Allotrichia McLachlan from Japan for the first time. For a sixth species, Stactobia distinguenda Nozaki and Botosaneanu 1996, previously known in Japan from the male only, the larva and its case are described.

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.

Shallow Coastal Waters

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.
