The benthic dinoflagellate genus Amphidinium in south-eastern Australian waters,including three new species

Seventeen species of the mainly sand-dwelling genus Amphidinium are reported from south-eastern Australian waters. Three new species are described: A. boggayum, A. mootonorum and A. yuroogurrum. Additional features from previously described species are presented, including non-motile cell stages. Nine of these species are new records for Australia; however, these species are probably widespread and common. Two potentially ichthyotoxic species of Amphidinium were commonly found: A. carterae and A. cf. operculatum. A table of morphological characters is compiled as a step towards recognizing new characters with which to group species of this presently artificially defined unarmoured dinoflagellate genus.     

Amiota sinuata species group from eastern Malaysia (Diptera, Drosophilidae)

Eight species of the Amiota sinuata species group are reported from eastern Malaysia, including six new species, A. bispinula, A. cerata, A. curvibacula, A. lambirensis, A. parviserrata and A. quadrifoliolata spp. nov. A key to Asian species of the group is provided.     

Two new species of night monkeys,genus Aotus (Cebidae,platyrrhini): A preliminary report on Aotus taxonomy

The nine allopatric species of Aotus recognized represent two natural groups distinguished by karyotype, color, and pelage patterns. Correlated with these group characters are reported differences in serum proteins and degrees of susceptibility or immunity to experimental infection with malarial parasites. The primitive gray-neck species group of Aotus contains A. brumbacki (new species), A. lemurinus (with subspecies lemurinus and griseimembra), A. trivirgatus, and A. vociferans. The derived red-neck group contains A. nancymai (new species), A. miconax. A. infulatus, and A. azarae (with subspecies azarae and boliviensis). Only the two new species are described but a key to the species and subspecies gives the diagnostic characters of each. The gray-neck group occurs almost entirely north of the Amazon, the red-neck group almost entirely south. The distributional exceptions are enclave populations resulting from river bend cutoffs. Formation of an enclave population of A. nancymai is discussed and available information on the biology of this species is reported.     

Revision of the genus Thambemyia Oldroyd (Diptera: Dolichopodidae) with description of a new subgenus

On the Paleozoic bryozoans of the genus <Emphasis Type="Italic">Ascopora</Emphasis> Trautschold

Based on the study of the neotype and the astogeny of the type specimens of the species Ascopora nodosa (Fischer von Waldheim, 1837), the diagnosis and species composition of the genus Ascopora Trautschold, 1876 are emended. The genus Ascopora and three species out of the five included in this genus—A. nodosa (Fischer von Waldheim, 1837); A. sokolovae Schulga-Nesterenko, 1955; and A. latiaxis Schulga-Nesterenko, 1955—are described. A new genus, Tetrasella gen. nov., with the type species T. blanda sp. nov. is described. This genus comprises five species, transferred from the composition of the genus Ascopora. An emended diagnosis of the genus Ascoporella Krutchinina, 1986, is provided. This genus comprises nine species, of which two, A. lecta sp. nov. and A. mera sp. nov., are described as new species.

The Group of Amphinemura flavostigma (Plecoptera,Nemouridae)

Three closely related species from Japan are treated and defined as composing the Amphinemura flavostigma group (Okamoto, 1922). One species, A. nikkoensis, is described as new to science. Two already known species, A. flavostigma and A. monotuberculata (Kawai, 1956), are redescribed, while the female of the latter is described for the first time. Another species, A. tetraspinosa Kawai, 1960, is regarded as a subjective synonym of Nemoura flavostigma Okamoto, 1922.     

Reproductive Ecology and Host Utilization of Four Sympatric Bitterling (Acheilognathinae,Cyprinidae) in a Lowland Reach of the Harai River in Mie,Japan

Bitterling are fishes that use freshwater mussels for oviposition. The reproductive ecology and pattern of mussel utilization of four sympatric species of bitterling, Acheilognathus rhombeus, A. tabira tabira, Tanakia lanceolata, and T. limbata, were investigated in a lowland river with seven sympatric mussel species. Three bitterling species are spring spawners with overlapping spawning seasons. A. rhombeus is an autumn-spawning species and is temporally isolated in its reproduction from the other species. Ovipositor length during oviposition of T. limbata and T. lanceolata was short, while those of A. tabira tabira and A. rhombeus were long. Most T. limbata inhabited near-shore areas, whereas the two other spring-spawning species were distributed across the entire river. All bitterling species used Inversidens brandti, Obovalis omiensis and Inversiunio jokohamensis as spawning hosts, but not the other mussel species available. T. lanceolata, A. tabira tabira and A. rhombeus showed spawning preferences for O. omiensis and I. brandti. However, T. limbata did not show clear preferences for any of the mussel species they used. A. t. tabira showed a significant preference for large I. brandti in offshore areas, while the other spring-spawning bitterling showed a preference for mussels inshore. These results are discussed in the context of reproductive resource partitioning.     

Three new species of <Emphasis Type="Italic">Anthocephalum</Emphasis> Linton, 1890 (Cestoda: Tetraphyllidea) from dasyatid stingrays of the Gulf of California

Three new species of Anthocephalum Linton, 1890 are described from dasyatid stingrays collected in the Gulf of California. Anthocephalum michaeli n. sp. is described from Dasyatis longus (Garman). This species most closely resembles A. alicae Ruhnke, 1994, but differs from this species in proglottid number. A. lukei n. sp. is also described from D. longus. This new species is most similar to A. cairae Ruhnke, 1994, but differs from that species in marginal loculi number and number of proglottids. The third new species, A. currani n. sp., is described from D. brevis (Garman). This species is most similar to A. centrurum (Southwell, 1925) Ruhnke, 1994, but differs from that species in marginal loculi number, number of testes and ovarian length. Phyllobothrium kingae Schmidt, 1978 is also consistent in morphology with species of Anthocephalum and is transferred to this genus, forming the new combination Anthocephalum kingae n. comb. This species most closely resembles A. michaeli n. sp., but differs in testicular shape. This brings the total number of species of Anthocephalum to nine. The transfer of the species Phyllobothrium arctowskii Wojciechowska, 1991, P. georgiense Wojciechowska, 1991, P. rakusai Wojciechowska, 1991 and P. siedleckii Wojciechowska, 1991 to Anthocephalum is not warranted, as these four species lack a posteriorly recurved cirrus-sac and a sinuous vagina, and have vitelline follicles uninterrupted by the ovary. Of the nine known species, all are parasitic in batoid fishes, and six are found in species of Dasyatis Garman. The phylogenetic status of Anthocephalum species in relationship to Rhinebothroides Mayes, Brooks & Thorson, 1981, Pararhineothroides Zamparo, Brooks & Barriga, 1999 and other rhinebothriin taxa is discussed.     

Notes on the genus Agnetina (= Phasganophora) (Plecoptera: Perlidae)

Genus Agnetina Klapálek, 1907 is removed from synonymy with Dinocras Klapálek, 1907 and synonymy between Agnetina and Phasganophora Klapálek, 1914 is established. A list of presently recognised nominal species of Agnetina is provided. For all west palaearctic species, i.e., A. elegantula (Klapálek), A. senilis Klapálek, A. werneri (Kempny), comb, n., lectotypes are designated. Distinctive characters of these three species are described, external male genitalia and eggs are illustrated. Asian A. brevipennis (Navás), comb, n., is briefly compared. A. dubia nom. n. is proposed to replace A. brevipennis Klapálek, 1921 (not Navás, 1912), a doubtful Asian species. A. pedata (Koponen, 1949) and A. undaata (Klapálek, 1921) are considered possible synonyms of A. senilis. which is for the first time recorded from Central Asia (Baikal area).     

A revised synopsis of the genus Atractomorpha Saussure, 1862 (Orthoptera:Pyrgomorphidae), with an account of the African aberrans - group

Recent work has shown that the preliminary revision of Atractomorpha by Banerjee & Kevan (1960), while basically not altogether unsatisfactory, is in need of considerable modification. The most important changes made include the recognition, as good species, of a number of taxa previously relegated to synonymy or to subspecific status. Two previously undescribed species have been discovered in the African a&errans-group, and two new subspecies are erected. The conclusions are largely based upon a study of the phallic structures, which had not previously been deemed satisfactory in providing diagnostic characters. The variability of these structures in the various species is illustrated, including that due to immaturity in two of them. The concealed female copulatory structures are also figured. A new key to species and subspecies (as well as an abridged key) is presented. New species are:A. occidentalis and A. orientalis. New subspecies are:A. sinensis montana and A. psittacina affinis. Species resurrected from synonymy are:A. rufopunctata Bolivar, A. himalayica Bolivar, A. angusta Karsch, and A. similis Bolivar, of which A. australiana Bolivar proves to be a synonym, and not a subspecies of A. crenaticeps (Blanchard). The other species re-elevated from subspecific rank is A. rhodoptera Karsch. Further changes in synonymy are as follows:A. lanceolata Bolivar is a synonym of A. burri Bolivar and not of A. rhodoptera; A. dentifrons Bolivar is a synonym of A. similis and not of A. crenaticeps; A. brevicornis (Thunberg) is removed from partial synonymy with A. lata (Motschoulsky). A. blanchardi Bolivar is not synonymous with A. crenulata (Fabricius) but is conspecific with A. acutipennis (Guérin-Méneville) and is here tentatively recognized as a widely distributed south-west Asiatic subspecies (in place of A. brevis Uvarov, which, as now understood, is restricted to south-west Arabia). A. crenulata apparently has a more restricted distribution than previously thought, being largely replaced or complemented by A, angusta, except in India and Ceylon. Neotypes are designated for A. acutipennis blanchardi and for Truxalis oceanicus Montrouzier (=A. crenaticeps). Information regarding the type specimens of all nominal species of Atractomorpha except A. nipponica Steinmann is given, and lectotype designations are made wherever necessary. Photographs of almost all primary types, except that of A. nipponica, that have not previously been so illustrated are present. This last species may be a synonym of A. rufopunctata.
