Two new genera of Bryozoa (Calloporidae) from New Zealand

Two new genera of the bryozoan family Calloporidae are described from New Zealand. The first, Leptinatella, is introduced for L. gordoni n. sp., specimens of which have been referred in the past to Watersia militaris (Waters) but are distinct from this species, which is a phase of the cribrimorph Corbulipora tubulifera (Hincks). The second genus, Bryocalyx, is introduced for B. cinnameus n. sp., which has small, conical colonies anchored by rhizoids. Another species of Bryocalyx is known from a few fragments only: and has also been referred in the past to Watersia sp. It is briefly discussed, but left unnamed here.     

Two new phoxocephalids (Crustacea: Amphipoda: Phoxocephalidae) from the south-west Atlantic

A new genus and species, Parafoxiphalus longicarpus, and a new species, Metharpinia protuberantis belonging to the family Phoxocephalidae, are described from the Argentine Sea. Both taxa were collected from sandy substrata in the intertidal and subtidal regions. Parafoxiphalus longicarpus is related to Foxiphalus Barnard, 1979 and they share many characters, most of them in plesiomorphic condition. Metharpinia protuberantis is an intermediate species between Metharpinia Schellenberg, 1931 and Microphoxus Barnard, 1960, and its assignation to the first genus is discussed.     

A review of the genus Talavera Peckham and Peckham, 1909 (Araneae,Salticidae)

The species of the Holarctic jumping spider genus Talavera are reviewed. Five new species are described: Talavera ikedai sp. n. (¦ §) from Japan and Korea; T. krocha sp. n. (¦ §) from France, Ukraine and Kyrghyzstan; T. parvistyla sp. n. (¦ §) from central and northern Europe; T. sharlaa sp. n. (§) from Tuva; and T. tuvensis sp. n. (¦) from Tuva. A lectotype is designated for Euophrys monticola Kulczy ` ski, 1884. A key to the 14 species now encompassed in this genus, and distributional maps, are provided for all of them. Arguments are given for placing the names Euophrys poecilopus Thorell, 1873 and Attus westringi Simon, 1868 as nomina dubia. Talavera aperta Miller, 1971 is removed from synonymy with both Talavera monticola (Kulczy ` ski, 1884) and Talavera thorelli (Kulczy ` ski, 1891).     

The soil mite family Eremaeidae (Acari: Oribatida) in Mongolia,with remarks on distribution and diversity of known genera

The oribatid mite family Eremaeidae is represented in Mongolia by eight species in three genera. Three new species, Eueremaeus tenuisensillatus sp. nov., Eu. crassisetosus sp. nov. and Eu. laticostulatus sp. nov., collected from cool temperate forests, dry steppe and semi-desert habitats in central and southern Mongolia, are described on the basis of adults. Five known species, Eremaeus hepaticus C. L. Koch, Eu. oblongus (C. L. Koch), Eu. granulatus (Mihel?i?), Proteremaeus mongolicus (Golosova) and P. punctulatus Bayartogtokh are redescribed; the first three of these are recorded for the first time from Mongolia. Taxonomic status of Eu. granulatus (Mihel?i?) and Eu. silvestris (Forsslund) is discussed, and the latter is considered a junior synonym of the former species. The following new combinations are proposed: Eueremaeus brevifer (Mahunka), Eueremaeus fossulatus (Kunst) and Eueremaeus roissi (Piffl). A key to Mongolian species of Eremaeidae is given. Data on distribution and diversity of Eremaeidae of the world are discussed.

Summary

Five early ontogenic stages of Scomberomorus lineolatus (C. &; V.) ranging in standard length from 18·4 mm to 99·5 mm are described.

Direct comparison of these early stages with those of S. commerson (Lac.) showed differences in the number of gill rakers, the length of preopercular spines and the position of the anal fin in relation to the second dorsal fin. In the case of S. guttatus (Bl. &; Schn.) the gill rakers are of the same number as in S. lineolatus but the preopercular spines decrease in size from above with the upper two subequal in size and none projects beyond the operculum.

In the earlier stages, S. lineolatus could be easily distinguished from S. guttatus by the absence of the bluish green coloration characteristic of S. guttatus. In later stages when the coloration has developed in both the species the only marked difference between the two is in the nature of the bent portion of the lateral line which is wavy in S. lineolatus and straight in S. guttatus.

The number of vertebrae is 46 in S. lineolatus; 42–45 with 43·9 as mean in S. commerson and 47–52 with 49·7 as mean in S. guttatus.     

A review of Eunotinae (Hymenoptera: Chalcidoidea: Pteromalidae) from China

Five genera of Eunotinae are included in this paper. Ophelosia, Moranila, Cephaleta, Eunotus are reviewed and a new genus Cavitas is described. Four new species, Cavitas concava sp. nov., Eunotus applanatus sp. nov., E. strenus sp. nov. and E. aequalivenus sp. nov. are described. The type specimens are deposited in the Zoological Museum, Institute of Zoology, the Chinese Academy of Sciences.     

A revision of the Asian and European species in the subgenus Amiota Loew (Diptera,Drosophilidae) and the establishment of species-groups based on phylogenetic analysis

A total of 53 Amiota (s. str.) species (75% of the world total) from Asia and Europe, including 10 new species, kamui, kimurai and planata from Japan, and aristata, cuii, macai, magniflava, nuerhachii, spinata and watabei from China, are reviewed with designation of two new synonymies and phylogenetic analysis. Based upon the result of cladistic analysis with 31 adult male morphological characters, the following conclusions are deduced: (1) The subgenus Amiota is monophyletic, so far as the Asian and European forms are concerned. (2) Seven monophyletic groups are recognized within this subgenus. Two of them correspond to known species-groups, the apodemata and sinuata groups, and the remaining five are established as new species-groups, the nagatai, basdeni, taurusata, alboguttata and rufescens groups. A key to all the studied species from Asia and Europe is provided.
