New species and rediagnosis of Coecobrya (Collembola: Entomobryidae), with a key to the species of the genus

The history of Coecobrya is traced and the genus is redefined. Two new species are described and one known species is redescribed in this paper: Coecobrya lanna sp. nov., Coecobrya tukmeas sp. nov. and Coecobrya aokii (Yoshii, 1995 Yoshii, R. 1995. Notes on Collembola of Vanuatu. Acta Zool Asiae-Orient., 3: 43–50.  [Google Scholar]). Additional details are provided for three other species Coecobrya guanophila Deharveng, 1990 Deharveng, L. 1990.

Complete S-chaetotaxy of the dorsal tergites is illustrated for the first time in the genus. Sinella ciliata Denis, 1932 is synonymized with C. tenebricosa. A key to the world species of Coecobrya is given.     

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.     

Crab‐associated amphipods from the Falkland Islands (Crustacea,Peracarida)

Four species of associated amphipods were collected from the lithodid crab Paralomis granulosa in the Falkland Islands: Jassa kjetilanna n. sp. (Ischyroceridae), Gammaropsis monodi (Schellenberg, 1931 Schellenberg, A. 1931. Gammariden und Caprelliden des Magellangebietes, Südgeorgiens und der Westantarktis.. Further Zoological Results of the Swedish Antarctic Expedition 1901–1903, 2: 1–290.  [Google Scholar]) (Photidae), Aora karibu n. sp. (Aoridae), and Paramoera falklandica n. sp. (Eusiridae s.l.). The Gammaropsis was also found on the majid crab Eurypodius latreillei, where it seemed to be the only associate. A survey of all amphipod associations involving lithodid crabs is provided.     

On a freshwater species of the genus Sanyuania Zhao and Han, 1980 (Crustacea,Ostracoda, Loxoconchidae) from Thailand,with a discussion on morphological evolution of the freshwater Loxoconchidae

The genus Sanyuania Zhao and Han, 1980 Zhao, G. and Han, D. 1980. “Late Quaternary brackish‐water ostracod faunas from the area to the west of Weishanhu Lake, Jiangsu and their significance.”. In Papers on Marine Micropaleontology, Edited by: Wang, P. 120–129. Beijing (China): Ocean Press.  [Google Scholar] is here transferred from the Cytherideidae to the Loxoconchidae, based on the morphology of valves and soft parts. Sanyuania segersi sp. nov., is described from a freshwater habitat, a river, in Thailand. This is the first record of this genus in Southeast Asia. The new species has a number of remarkable characters distinguishing it from other members in the genus and family: invicidont hinge, spearhead‐like protruding posterior extremity of carapace in dorsal view, subtriangular shape of carapace in lateral view, sieve plate without a central seta (sensillum) and an aberrant chaetotaxy of first and second antennae. The new taxon is compared with other recent freshwater loxoconchids [Cytheromorpha fuscata (Brady, 1869 Brady, G. S. 1869. Contributions to the study of the Entomostraca. IV. Ostracoda from the River Scheldt and the Grecian Archipelago.. Ann Mag Nat Hist ser 4., 3: 44–50.  [Google Scholar]), Elofsonia baltica (Hirschmann, 1909), Loxoconcha elliptica Brady, 1868, Loxoconcha galilea Lerner‐Seggev, 1968, Pseudolimnocythere hartmanni Danielopol, 1979 Danielopol, D.

The results from both types of analyses are congruent and reveal that Sanyuania segersi sp. nov., Pseudolimnocythere and Loxoconcha are in a more derived clade in the Loxoconchidae and are closely related to each other, whereas Cytheromorpha and Elofsonia are more ancestral.     

Tardigrades from the Tsinling Mountains,central China with descriptions of two new species of Echiniscidae (Tardigrada)

A checklist of 63 species of tardigrades from the Tsinling Mountains is given in this paper. Thirty‐seven species of tardigrades that had never been found in the Tsinling Mountains were reported here. Twenty of them are new records for the mountains, 15 of them are new records for China, two of them are new to science. Pseudechiniscus pilatoi sp. n. is similar to Pseudechiniscus quadrilobatus Iharos, 1969 Iharos, G. 1969. Einige Angaben zur Tardigradenfauna Vietnams.. Opuscula Zoologica, Budapest, 9(2): 273–277.  [Google Scholar]. It differs from P. quadrilobatus in different cuticular sculpture, in the joints of paired‐plates, near the dorsal median line, uplifting but not protruding backward, and in lacking notches on terminal plate. Echiniscus marleyi sp. n. differs from E. canadensis Murray in having filaments D; it differs from E. mediantus Marcus in lacking filaments C but in having filaments D; it differs from E. spinulosus (Doyère) in lacking teeth B, C, E, and in having filaments D instead of teeth D.

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. Bureau of Fisheries Document., 736: 1–44.  [Google Scholar]) from Agononida analoga (Macpherson, 1993); Aporobopyrus retrorsa (Richardson, 1910 Richardson, H. 1910.

All of these hosts, except for Paramunida scabra, are recorded for the first time bearing parasitic isopods.

Revision of the hirsuticornis‐like species of Macrothrix Baird, 1843 (Cladocera: Anomopoda: Macrothricidae) from Subantarctic and temperate regions of the southern hemisphere

The aim of this paper is to revise populations of Macrothrix cf. hirsuticornis (Cladocera: Anomopoda: Macrothricidae) from different regions of the southern hemisphere. It is demonstrated that M. hirsuticornis Norman and Brady, 1867 Norman, A. M. and Brady, G. S. 1867.

Archiv für Naturgeschichte, 44: 102–121.  [Google Scholar] from the Kerguelen Archipelago is redescribed and a neotype is selected. All populations in the southernmost portion of continental South America, Tierra del Fuego, Falklands, South Georgia, South Orkney Islands, and on the Antarctic Peninsula belong to M. oviformis Ekman, 1900 Ekman, S. 1900.

Mikroskopische Süsswasserthiere aus Patagonien, gesammelt von Dr. Filippo Sylvestri.. Természetrajzi Füzetek, Budapest, 25: 201–310.  [Google Scholar]—are junior synonyms of M. oviformis. Two new species are established: M. sarsi sp. nov. from the Cape region of South Africa and M. ruehei sp. nov. from Crozet, Marion islands, and Île Amsterdam.

[Crossref] , [Google Scholar], previously known only from Tasmania, is found on Macquarie Island too. Differences between species from the southern hemisphere and Palaearctic M. hirsuticornis are summarized. It is demonstrated that characters of the general body shape (i.e. presence of a hood or a tooth on posterior head border) have a limited value for the systematics of Macrothrix. In contrast, some fine details, mostly missed by previous authors, are valuable for species discrimination. The present study increases the number of species recorded from the Antarctic‐Subantarctic region. Probably, the current pattern of Macrothrix distribution results from a disruption of a pan‐continental (early Mesozoic?) species complex.
