A New Species

Leptoplectus kijimunaa Jałoszyński & Nomura, sp. n. is described, based on a series of specimens collected on Okinawa Island, Japan. Morphological structures of the new species are illustrated in detail and compared to known characters of all remaining 14 congeners. As the diagnosis of Leptoplectus remains unclear, character variability within known species is discussed. It is concluded that within Palaearctic region, the bilobed labrum is a reliable character to distinguish this genus from other Euplectini. The placement of Labroplectus Kurbatov, treated as incertae sedis within the tribe Trichonychini in the latest edition of the Catalogue of Palaearctic Coleoptera, is verified and it is concluded that it should be maintained in Euplectini. An identification key to genera of northeastern Asian Euplectini is given. We also comment on outdated and inaccurate morphological nomenclature still broadly used in descriptions of new Pselaphinae taxa.

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

During our studies on the Diptera fauna of the Caspian Hyrcanian mixed forest, Golestan province, Iran, a new species of the genus Clistoabdominalis (Pipunculidae) was identified. In the present paper we name, describe and illustrate Clistoabdominalis hyrcania sp. nov.. An identification key to the males of the Clistoabdominalis ruralis species group from the Western Palaearctic region is provided.

A new thermosbaenacean, Halosbaena okinawaensis sp. nov. is described from a submarine cave in Okinawa Island, Ryukyu Islands, southwestern Japan. The species differs from its congeners in having a subtrapezoidal exopod segment 1 of pereiopods 2–6, a curved penial lobe, and a telson with a pair of simple macrosetae subdistally on dorsal surface.

A New Species

A new species of the genus Comanthus A.H. Clark, 1908, is described on the basis of specimens collected from KumeIsland and Okinawa Island, the Ryukyu Islands, Japan. Comanthus kumi n. sp. is distinguished from all ten congeners byhaving extremely elongate arms exceeding 300 mm in length and the colouration in life. The new species concealed itswhole body in a crevice or small hole on coral reefs during the day and protruded only several elongate arms on the reef surface at night. This habit suggests that the new species is nocturnal.

Egglestonichthys fulmensp. nov. (Teleostei: Gobiidae) is described on the basis of a single specimen (21.7 mm in standard length) collected from 250 m depth off Okinawa Island, Ryukyu Islands, Japan. The new species is characterized by the following combination of characters: anal-fin rays I, 9; pectoral-fin rays 17, lower rays not free from membrane; longitudinal scale series 25; transverse scales 8; pre-dorsal-fin scale rows 8; cheek and opercle naked; pelvic frenum absent; caudal fin lanceolate, its length 32.2% of SL; interorbital width very narrow, 1.2% of HL (much narrower than pupil diameter); no spicules or odontoid processes on outer surface of gill arches; and body whitish, upper half with broken zigzag pattern of bright yellow patches and associated scattered black melanophores in fresh specimens (melanophores retained in preserved specimens). Several characters, including pectoral-fin ray count, interorbital width, and coloration uniquely distinguish the new species from congeners.

The cixiid planthopper genus Indolipa Emeljanov, 2001 is revised taxonomically. Seventeen species are recognized of which one, Indolipa gansuensis sp. nov., is new to science. Indolipa kureongensis (Distant, 1911) and I. gansuensis represent the first record of the genus for the Palaearctic Region. A list of all known species of the genus Indolipa is given as well as new descriptions, illustrations and an identification key to Chinese species.
