Herein two new species of the genusSyngastesMonard, 1924 are described from South Korea, with detailed descriptions and illustrations. Both new copepods,Syngastesmulticavussp. nov. andS. pseudofoveatussp. nov., have two inner setae on the first exopodal segment of P2 and P3.Syngastesmulticavussp. nov. most closely resemblesS. gibbosusBartsch, 1999 reported from Australia, as they both have a five-segmented antennule in the female. However,Syngastesmulticavussp. nov. has a rounded body outline instead of the gibbose outline observed inS. gibbosus.Syngastespseudofoveatussp. nov. resemblesS. foveatusBartsch, 1994 in almost all aspects. However, they differ clearly in the number of setae on the first exopodal segment of P2 and P3. We also provide a key to species of the genusSyngastesworldwide. The present study is the first record of the family Tegastidae in Korean waters.

Species Being

Cryptopontius is the most species-rich genus in the family Artotrogidae with 25 species, being recorded in almost all oceans, except in the Arctic. However only three species of this genus have been recorded from the Brazilian coast, all of them along the coast of Pernambuco state. This study describes two new species of the genus. Cryptopontius phyllogorgius sp. nov. differs from other species by having 9-segmented antennule, and nine elements on the third exopodal segment of leg 4. Cryptopontius pentadikos sp. nov. differs from its congeners by having five expressed antennulary segments proximal to fused ancestral IX-XII, two setae on second endopodal segment of leg 1, eight elements on third exopodal segment of leg 1 and the free segment of leg 5 with two setae. A key to species of the genus Cryptopontius is provided.

Abstract. Two new fossil species of Baltocar Kuschel, 1992 and Pseudomesauletes Legalov, 2001 (Curculionoidea: Rhynchitidae) are described from Eocene Baltic amber. Baltocar sontagae sp. nov. is similar to B. groehni Riedel, 2012 but differs in the shorter rostrum, tarsomere 1 shorter than tarsomere 5 and 1.4× as long as tarsomere 2, longer elytra, and shorter body. Pseudomesauletes lobanovi sp. nov. is similar to P. culex (Scudder, 1893) and P. ibis (Wickham, 1912): the new species differs from P. culex in the larger eyes, longer pronotum, being 0.44× shorter than elytra, and slightly smaller body size; from P. ibis it differs in the smaller body size, rostrum shorter than elytra, and weakly convex pronotum. This is the first record of Pseudomesauletes from Baltic amber and the sixth species of Baltocar. Keys to species of the genus Baltocar and to the Eocene species of the genus Pseudomesauletes are given. Assumed trophic relationships of these fossil taxa are discussed (urn:lsid:zoobank.org:pub:260EBE6E-DA6C-4D6D-A1D2-2C258224622F).

Two new species of Discorhabdella are described from Sagami Bay, Japan. Discorhabdella has been suggested to have an ancient Tethyan origin according to discovery of their unique pseudoastrose acanthostyles from late Eocene to Oligocene deposits. This is the first record of the genus from the northwest Pacific and first record of the family Crambeidae from Japan. Discorhabdella hispidasp. nov. is distinctive within the genus by possession of special sigmoid microscleres and C-shaped isochelae with short alae. Discorhabdella misakiensissp. nov. is characterized by short choanosomal subtylostyles, and their length overlapped with that of the ectosomal subtylostyles. Only one other species, Discorhabdella tuberosocapitata (Topsent, 1890), has the same spicule composition. However, all spicule types are larger in D. tuberosocapitata than those of D. misakiensissp. nov., and the shape of the isochelae is different: the alae are more widely opened in D. tuberosocapitata. An identification key to species of the genus Discorhabdella is also provided. The discovery of two new species from warm temperate northwest Pacific extends the geographical distribution of the genus Discorhabdella.

Stenosternum cordata sp. nov. and Stenosternum bifurcata sp. nov., new to science, are described, which is the first record of Hoplomegistidae from Asia. Stenosternum cordata sp. nov. is distinguished by its heart-shaped latigynal shield with two pairs of setae along the lateral margin, and two pairs of setae along the posterior margin of the sternal shield. Stenosternum bifurcata sp. nov. is distinguished by having remarkable bifurcate corniculus, six pairs of setae on the sternal shield and three pairs setae on the latigynal shield. The family Hoplomegistidae Camin & Gorirossi, 1955 is redefined and a key to adult females of species is provided.

Two new free-living marine nematodes of the family Oxystominidae are described from San Antonio Bay (Río Negro) and San José Gulf (Chubut). Litinium australis sp. n., is characterized by having a rounded tail, by the first and second crown of cephalic setae with different lengths, gubernaculum with apophysis and by the presence of at least four precloacal papillae; Thalassoalaimus nestori sp. n., is characterized by having a conical tail, cephalic setae equal in length, gubernaculum with rounded and dorso-caudally directed apophysis and two precloacal papillae. An emended diagnosis of the genus Thalassoalaimus and a key to species are given.

Three amphipods of the family Photidae collected from Korean waters are reported here with detailed descriptions and illustrations. The Korean materials of Gammaropsis examined in this study are readily assigned to G. longipropodi by the characteristic shape of gnathopod 2 in males: not slenderly produced posterior margin of the carpus, uniform width of very elongate propodus, and the transverse palm. Among the species of genus Photis, P. fischmanni is only one species bearing stridulation ridges of the basis on gnathopod 2 and coxa 3 simultaneously in females, until now. However, Photis stridulus sp. nov. also show this characteristic but is clearly distinguishable from P. fischmanni by the weak setation of the appendages, smaller eye on the anterior cephalic lobe, and the slender carpus and propodus on gnathopod 1. The genus Podoceropsis is recorded from Korean waters for the first time with the discovery of P. clavapes sp. nov. This new species is characterized by its elongate propodus and dactylus on gnathopod 2 and the shape of the posterior lobe of the basis on pereopod 5 in mature males.

The oribatid mite family Liacaridae (Acari, Oribatida) is recorded in Vietnam for the first time. Two new species of liacarids of the genera Liacarus and Xenillus are described from Tam Dao National Park, northern Vietnam. Liacarus vietnamensis sp. nov. is similar to L. laterostris Mihelčič, 1954 in the morphology of lamellar cusps (inner teeth well-developed; interlamellar tubercle absent) and in having long interlamellar setae and short notogastral setae, but differs by the directions of lamellar cusps and morphology of bothridial setae. Xenillus tamdaoensis sp. nov. is similar to X. longipilus Pérez-Íñigo & Peña, 1995 in having long notogastral setae, insertion of notogastral setae lm posterior to la, and the presence of an interlamellar tubercle, but differs by the morphology and position of lamellar cusps, size of the interlamellar tubercle and length of interlamellar setae.

A New Species

Polycheria acercaudasp. nov., an amphipod symbiotic with sponges and ascidians in Korean waters, is established herein as a new species, along with a detailed description and illustrations. This new species is closely related to the following three known species of the genus from the Far East:Polycheria amakusaensisHirayama, 1984,P. japonicaBulycheva, 1952, andP. orientalisHirayama, 1984. However,Polycheria acercaudasp. nov. can be distinguished from the other congeners by the following combination of characteristics: (1) on antenna 2, the anterior margin of peduncular article 4 is pubescent; (2) on gnathopod 2, the palm is clearly distinct; (3) on uropod 3, the inner ramus is lined with plumose setae; and (4) on the telson, the apices are acute. This is the first report of the genusPolycheriaHaswell, 1879 belonging to the family Dexaminidae Leach, 1814 from Korean waters.
