New records and hosts for three species of pseudionine bopyrids (Crustacea: Isopoda: Bopyridae) parasitizing munidid squat lobsters (Crustacea: Anomura: Munididae) in Philippine waters

Three species of pseudionine bopyrid isopods infesting four species of munidid squat lobsters are reported from Philippine waters: Pleurocryptella laevis (Richardson, 1910 Richardson, H. 1910. Marine isopods collected in the Philippines by the U. S. Fisheries steamer Albatross in 1907–8.

Marine isopods collected in the Philippines by the U. S. Fisheries steamer Albatross in 1907–8. Bureau of Fisheries Document., 736: 1–44.  [Google Scholar] from Paramunida scabra (Henderson, 1885). All of these hosts, except for Paramunida scabra, are recorded for the first time bearing parasitic isopods.     

Four new records and a new species of Dactylokepon Stebbing, 1910 (Epicaridea: Bopyridae: Ioninae) from Chinese waters

Five species of the parasitic isopod genus Dactylokepon are described from brachyuran crabs and a scyllarid shrimp collected in Chinese waters.

First record of the genus Gigantione (Epicaridea: Bopyridae: Pseudioninae) from Chinese waters,with description of three new species

The parasitic isopod genus Gigantione is first recorded from China. Four species are reported infesting xanthid and goneplacid crabs, three are new to science, and one is a new record from China. Gigantione ishigakiensis Shiino, 1941 Shiino, S. M. 1941. Further notes on Bopyrids from Kyûsyû and Ryûkyû..

Four brachyuran crabs are first reported as hosts of bopyrids. A list of all brachyuran species so far recorded as bopyrid hosts in China is provided.     

Establishment of a new subfamily for Shenius anomalus (Shen, 1935) (Crustacea: Decapoda: Brachyura: Dotillidae)

Shenius anomalus (Shen, 1935 Shen, CJ. 1935. On some new and rare crabs of the families Pinnotheridae, Grapsidae and Ocypodidae from China. Chin J Zool., 1: 19–40. 15 figures [Google Scholar]) has previously been assigned to the Macrophthalmidae Dana, 1851, and the Camptandriidae Stimpson, 1858 Serène, R. 1974. Note on the genera and species of the Camptandriinae Stimpson, 1858 (Decapoda, Brachyura: Ocypodidae). Treubia, 28(3): 59–117.  [Google Scholar]. A close examination of adult and first stage zoeal morphology confirms some previous suggestions that S. anomalus is actually an anomalous member of the Dotillidae Stimpson, 1858 Serène, R. 1974. Note on the genera and species of the Camptandriinae Stimpson, 1858 (Decapoda, Brachyura: Ocypodidae). Treubia, 28(3): 59–117.  [Google Scholar]. However, because a number of distinctive features distinguish it from all other dotillid genera a new subfamily Sheniinae is established.     

Heteromysoides (Crustacea: Mysidacea: Heteromysini) from a submarine cave on Grand Cayman,the Caribbean Sea: descriptions of a new and a rare species

During a recent biological investigation of submarine caves of Grand Cayman, the Caribbean Sea, two species of Heteromysoides were collected. One species, referred to Heteromysoides spongicola B?cescu, 1968 Baˇcescu, M, 1968. Heteromysini nouveaux des eaux cubaines: trois espèces nouvelles de Heteromysis et Heteromysoides spongicola n. g. n. sp., Revue Roumaine de Biologie, Zoologie 13 (1968), pp. 221–237. [Google Scholar], is known only by the type specimens; therefore, this discovery marks the second record of occurrence and a new habitat record for the species. The other species is considered new and is described as H. stenoura, a 10th species of the genus. The new species closely resembles H. simplex Hanamura and Kase, 2001 Hanamura, Y, and Kase, T, 2001. A new species of Heteromysoides (Mysidacea: Mysidae) from submarine caves of Okinawa, southwestern Japan, with a key to the world species, Crustacean Research 30 (2001), pp. 65–71.[Crossref] , [Google Scholar], known from the submarine caves of Okinawa, north-western Pacific, in the possession of a spiniform process on the eyes and a simple termination to the third thoracic endopod. However, the new species can be readily distinguished from the Pacific congener by a distally narrow telson and a more developed cornea in the eyes.     

Revision of the genus Peraeospinosus Sieg, 1986 (Crustacea: Peracarida: Tanaidacea)

Ten species, four new to science, five formerly belonging to genus Typhlotanais, and Peraeospinosus pushkini (Tzareva, 1982 Tzareva, L. A. 1982. “Dopolnenie k faune kleshnienosnykh oslikov (Crustacea: Tanaidacea) shelfovykh zon Antarktiki i Subantarktiki.”. In Fauna i raspredelenie rakoobraznych notal'nych i antarkticheskikh vod, Edited by: Kavanov, A. I. 119Vladivostok: Akademia Nauk SSSR.  [Google Scholar]) are congeneric species, based on the following set of characters: a row of setae is present on the dorsal margin of the cheliped carpus, the distal seta of pereopods 4–5 exceeds the bifurcated unguis, large prickly tubercles on pereopods 4–6 surrounded by well‐calcified spines, the pleopods semi‐elliptical, and the rami of the uropod subequal in length. The new definition of the genus is proposed together with a key for identification of the females. The present‐day distribution of the genus does not in itself indicate geographical origin, although the possibility of a deep‐water origin cannot be excluded. It is assumed that phylogenetically young, blind Peraeospinosus could have colonized Antarctic free niches and then radiated.     

Designation of Thouarella abies Broch, 1965 as the type species of the subgenus Fannyella (Scyphogorgia) Cairns and Bayer, 2009, and description of a new genus for Stenella (Dasystenella) liouvillei Gravier, 1913 (Octocorallia: Primnoidae)

Recently the two Antarctic gorgonian species Stenella (Dasystenella) liouvillei Gravier, 1913 Gravier, CH. 1913. Seconde Expédition Antarctique Française (1908–1910). Alcyonaires (2° note préliminaire). Bull Mus Nat Hist Nat. Paris, 19: 589–593.  [Google Scholar] and Thouarella abies Broch, 1965 Broch, H. 1965. Some octocorals from Antarctic Waters. Scientific Results of the “Brategg” Expedition, 1947–48. Christensens Hvalfangstmus i Sandejford Publ., 26: 19–38.  [Google Scholar] were synonymized and considered as Fannyella (Scyphogorgia) liouvillei. The re-examination of the type material of both species and newly collected specimens demonstrate that this synonym can no longer be considered valid. In the present study we propose, following the International Code of Zoological Nomenclature, to change the current type species of the subgenus Scyphogorgia, Stenella liouvillei, to Thouarella abies, the new combination being Fannyella (Scyphogorgia) abies. Furthermore we propose a new genus, Scopaegorgia, to accommodate Stenella liouvillei. Both species are completely re-described from the type material and the abundant specimens collected during some recent Antarctic cruises.     

Review of the genus Calamotropha Zeller (Lepidoptera: Crambidae: Crambinae) from China,with descriptions of four new species

Four new species of the genus Calamotropha Zeller are described from China: Calamotropha duofurcata sp. nov., Calamotropha abrupta sp. nov., Calamotropha aequilata sp. nov. and Calamotropha unispinea sp. nov.

Caridina pareparensis parvidentata is here regarded as a distinct species. The new taxa are described, figured and compared with congeners.     

On the South American species of the genus Meridiosignum (Crustacea: Isopoda: Asellota: Paramunnidae)

Meridiosignum undulatum n. sp. and M. disparitergum n. sp. are described from off the Río de la Plata estuary. These two new species are easily distinguished from other members of the genus Meridiosignum in having the lateral margins of pereonites 2 and 3 bilobed (the concavity is much more pronounced in M. disparitergum), and those of pereonite 4 produced into a single process. The terminal male instar of Meridiosignum menziesi (Winkler, 1994 Winkler, H. 1994. Paramunnidae (Crustacea: Isopoda: Asellota) from the Magellan Strait.. Zool J Linn Soc., 110: 243–296. [Crossref] , [Google Scholar]) is described, and this species is herein reported from the Beagle Channel and Puerto Deseado. All the species currently placed in Meridiosignum were found in shallow waters in the southern hemisphere, M. undulatum n. sp. and M. disparitergum n. sp. being the species recorded at the greatest depth (129 m).     

Australian species of Sinella (Coecobrya) Yosii, 1956 (Collembola: Entomobryidae)

The Australian members of the subgenus, Sinella (Coecobrya) Yosii, are revised. A new species from Western Australia, Queensland, and the Northern Territory, Sinella (Coecobrya) tropicalis sp. nov., is described, Sinella (Coecobrya) tenebricosa Folsom, 1902 is recorded from Australia for the first time, and new records of Sinella (Coecobrya) communis Chen and Christiansen, 1997 Chen, J‐X. and Christiansen, K. A. 1997. Subgenus Coecobrya of the genus Sinella (Collembola: Entomobryidae) with special reference to the species of China.. Annals of the American Society of Entomology, 90: 1–19.  [Google Scholar] are documented. Sinella (Coecobrya) caeca Schött, 1896 is considered a dubious record from Australia. A key is provided to the three known Australian species and a summary given of all dorsal and lateral chaetal patterns found on the fourth abdominal segment of subgenera Sinella Brook, 1882 Brook, G. 1882. On a new genus of Collembola (Sinella) allied to Degeeria Nicolet.. Journal of the Linnean Society of London (Zoology), 16: 541–545.  [Google Scholar] and Coecobrya Yosii, 1956 Yosii, R. 1956.

A new species of the genus Nanosesarma (Crustacea: Decapoda: Brachyura: Sesarmidae), and redescription of Nanosesarma jousseaumei (Nobili, 1906), including new records from the Persian Gulf

A new species of sesarmid crab from the Persian Gulf, Nanosesarma sarii n. sp. is described. Further, a poorly known species, N. jousseaumei (Nobili, 1906 Nobili, G. 1906. Faune carcinologique de la Mer Rouge. Décapodes et Stomatopodes. Ann Sci Nat, Zool ser. 9., 4(1): 1–347.  [Google Scholar]), is recorded from the Persian Gulf and recognized as a valid species. N. sarii n. sp. is allied to N. minutum (De Man, 1887) and N. jousseaumei (Nobili, 1906) Nobili, G. 1906. Faune carcinologique de la Mer Rouge. Décapodes et Stomatopodes. Ann Sci Nat, Zool ser. 9., 4(1): 1–347.  [Google Scholar], but is easily distinguishable from them through a number of characters, in particular the upper surface of the palm with a longitudinal granular ridge, the upper surface of the movable finger fully covered with tubercles, and abdomen of the male with the sixth segment wide and the seventh segment remarkably elongate. N. jousseaumei differs from its remaining congeners in having a large gap between the cheliped fingers, a large tubercle proximally on the outer surface of the movable finger, and large teeth on the posterior margin of the merus of the walking legs.
