A New Species

We describe a new mite species from the Far East of Russia—Proctogastrolaelaps subsolanus Joharchi & Marchenko sp. nov. (Acari: Melicharidae). The new species was collected from soil-litter on the shores of the Tunaycha Lake and Sea of Okhotsk in Sakhalin Island. The important morphological characteristics of the genus Proctogastrolaelaps are revised.

A New Species

Daphnia curvirostris species complex is a cladoceran group (Crustacea: Cladocera) with maximum diversity in Eastern Palearctic. To date, several representatives of this complex are known from the Russian Far East. Here we describe a new species of the Daphnia sinevi species group from water bodies of Sakhalin Island. Morphology of its parthenogenetic females is similar to that in D. sinevi from the continental part of Asian Eurasia. However, we found diagnostic traits of D. sakhalinensis sp.nov. in morphology of the second pecten on postabdominal claw, armature of seta 2 on exopodite III, proportions of setae 1/ and 2 length on exopodite V, relative length of male rostrum and structure of the second pecten of male postabdominal claw. This work contributes to our full revision of the D. curvirostris species complex. Separation between continental and Sakhalin populations of D. sinevi group probably happened in Pliocene (about 5 MA) when Sakhalin began to separate from the mainland. However, we cannot exclude a version that populations of D. sakhalinensis sp.nov. appeared as a result of colonization of Sakhalin from the continent and further independent evolution of the island populations.

AbstractA taxonomic study of Megarthrus Curtis in Korea is presented. The genus is represented in Korea by 10 species including M. coreanus Kim and Cuccodoro sp. nov.Megarthrus corticalis Sharp, M. fennicus Lahtinen, M. incubifer Cuccodoro, M. japonicus Sharp, M. montanus Sawada, M. sawadai Cuccodoro, and M. zerchei Cuccodoro and Löbl are reported from Korea for the first time. A diagnosis of the genus and a key to the Korean species are provided. The new species is diagnosed, described, and illustrated and the other species are diagnosed and illustrated. Species distributions are presented, and the effect of these Korean findings on the level of endemism of the Megarthrus fauna of Japan and Far East Russia is discussed.

AbstractNew cercariae similar to those of Paracoenogonimus (Cyathocotylidae, Prohemistomatinae), have been found in gastropods Amuropaludina and Cipangopaludina from reservoirs of the Primorsky Region (southern Far East of Russia). Two species of freshwater fishes (Pseudorasbora parva and Perccottus glenii) were experimentally-infected second intermediate hosts. Adults reared in chicken, Gallus gallus dom. They belong to a new species, Paracoenogonimus ussuriensis sp. n. They differ from those of P. szidati (Anderson, 1914) and Mesostephanus appendiculatus (Ciurea, 1916) (=P. skworzowi (Petrov, 1950) sensu Sudarikov 1961) by the size of the body, pharynx and ovary and, further, from the latter by the size of the suckers and testes. Adults differ from P. ovatus Katsurada, 1914 by the smaller dimensions of the oral sucker, pharynx and testes, and also by the absence of anterior interval between vitelline follicles.

A New Species

This study reports on two species of the hippolytid shrimp genus Eualus Thallwitz, 1892 from Japan. The first, Eualusctenomerus n. sp., is described on the basis of six specimens from off southern Kyushu. The new species appears closestto E. cteniferus (Barnard, 1950) from South Africa, E. drachi Noël, 1978 from the Mediterranean, E. lebourae Holthuis,1951 from the eastern Atlantic, and E. pectiniformis Hanamura, 2008 from southeastern Australia. The second is referredto E. kikuchii Miyake & Hayashi, 1967, which has been considered to be synonymous with E. bulychevae Kobjakova,1955, described from the South Kuril Islands, Far East Russia. Eualus kikuchii is redescribed as a valid species on thebasis of the holotype and additional specimens from various Japanese localities. Both species occurred in the whale-fall ecosystems located off Cape Nomamisaki, Kyushu, Kagoshima Prefecture.
