To date, the family Pudeoniscidae includes six species and three genera, Pudeoniscus, Brasiloniscus and Iansaoniscus, with distributions restricted to Brazil. Here, we redefine the family Pudeoniscidae based on the discovery of a new genus and two new species, Oxossioniscus pataxo sp. nov. and Oxossioniscus akoko sp. nov., from the Brazilian Atlantic forest in the state of Bahia, and on the examination of Pudeoniscus birabeni and Pudeoniscus obscurus. Moreover, P. obscurus is re-described and new records are provided for P. birabeni.

A new genus of soil-inhabiting nematode belonging to the family Mydonomidae Thorne, 1964 is described and illustrated from natural forests of Arunachal Pradesh, India. Paratimmus provulvatus gen. nov., sp .nov. is characterized by having a continuous lip region; tiny, asymmetrical odontostyle; single distinctly sclerotized guiding ring; simple, rod-like odontophore; a thin sheath (not spiral) around basal pharyngeal bulb; elongate conoid cardia; mono-opisthodelphic female genital system; transverse vulva; long filiform tail in both sexes and males with dorylaimoid spicules and three to four spaced ventromedian supplements. 相似文献

Three new species of the harpacticoid family Ameiridae are described from clean sand at high water neap tide on St Martin's Flat, Isles of Scilly. Ameiropsis martinis sp. nov. appears most closely related to A. australis Kunz, 1975 but can be distinguished from it by the shape of the rostrum and the armature of the operculum, female genital field and the male P5 baseoendopodal lobe. Sarsameira parexilis sp. nov. was originally identified as S. exilis T. and A. Scott, 1894 but the females can be distinguished from S. exilis by their smaller body size and shape of the caudal ramus whilst the males can be distinguished by the 12-segmented antennule and four setae on the P5 baseoendopodal lobe. Ameira longispina sp. nov. is unique within the “Ameira” complex of genera and species because of the marked elongation of the inner spine on the basis of the male P1. This species is tentatively placed in Ameira Boeck, 1865, but has features which indicate that it probably occupies an intermediate position between this genus and Psammameira Noodt, 1952. The previously unknown males of Sarsameira perezi Bodin, 1970 and Nitocra elegans (T. Scott, 1905) are also described. 相似文献

A collection of ascidians from 100–1000 m deep off the north-western coast of Australia has yielded 19 species, including one new, two possibly endemic to the north-western coast of Australia, four well-known Indo-west Pacific tropical species and 12 species known from the deeper waters of the western Pacific, of which 11 had not previously been recorded from off the western Australian coast or from other parts of the Indian Ocean. A third of these 12 species displays adaptations for a reduction in filter-feeding capacity, as do other known species from deeper slope and abyssal habitats. Nevertheless a connection with fauna of deep ocean basins of the Indian Ocean is not apparent at this stage. The full range of characters associated with species, genera and families are discussed, and those contributing to the identification of immature or mutilated specimens, as well as those relevant to an assessment of phylogenetic relationships, are emphasized. 相似文献

Four nominal species of the genus Horatia Bourguignat, 1887 were described by Russian authors from Caucasian caves (H. borutzkii Shadin, 1932, H. birsteini Starobogatov, 1962, H. ljovushkini Starobogatov, 1962 and H. sokolovi Starobogatov, 1962). Hitherto all the species were known from type series (presented by empty shells) only. Examination of newly obtained samples from the caves of South Caucasus has shown that the four species actually do not belong to the genus Horatia due to obvious differences in the morphology of the copulatory organs between H. klecakiana Bourguignat, 1887 (the type species of this genus) and the Caucasian snails. Moreover, statistical analysis of conchological variation has revealed that the species H. birsteini, H. ljovushkini, and H. sokolovi are conspecific. Two genera are described: Pontohoratia (includes P. birsteini and P. smyri sp. nov.) and Motsametia (with the single species M. borutzkii comb. nov.). The two genera can be distinguished on the basis of the structure of their copulatory organs. The distribution and ecology of the Caucasian Horatia-like mollusks are briefly outlined.http://zoobank.org/urn:lsid:zoobank.org:pub:4EDFB2AE-CB1D-4113-8CC7-3A1BBB46D838 相似文献

The genus Chilarboreus gen. nov. is described from Nothofagus forests of Chile to accommodate three new species: Chilarboreus fossulatus sp. nov., Chilarboreus acuticollis sp. nov. and Chilarboreus darwini sp. nov. The genus is subdivided into two subgenera: Chilarboreus subgen. nov. (type species: C. fossulatus) and Pictarboreus subgen. nov. (type species: C. darwini). Identification keys to the genera of Chilean Scirtidae and the species in the genus Chilarboreus are provided. The state of knowledge of Chilean Scirtidae is summarized. The position of Chilarboreus within Scirtidae and the phenomenon of wing reduction in Scirtidae are discussed. 相似文献

本文描述了采自湘西北奥陶纪 Caradocian 期的三叶虫新属——Paratzuchiatocnemis(gen.nov.)(副自家虫),并进一步讨论此新属的特征与自家虫属(Tzuchiatocnemis),瘤肋虫属(Hammatocnemis)、卵形头虫属(Ovalocephalus)的异同及它们的相互关系与归属问题,认为宜将 Ovalocephalus、Tzuchiatocnemis 与 Paratzuchiatocnemis 三属划归为新亚科——卵头虫亚科〔Ovalocephanae(subfam.nov.)〕. 相似文献

A morphological investigation of Leydigia parva Daday, (Chydoridae: Anomopoda: Cladocera), based on specimens from Paraguay (type specimens) and Brazil, clarifies its position in the subfamily and prompts its assignment to a new genus, Parvalona. The affinity of this rare benthic chydorid with Leydigia Kurz, 1875 and Alona Baird, 1843, in which this taxon was placed earlier, is discussed. 相似文献

为了寻找EPSP合酶中某些与草苷膦抗性相关的位点,利用体外定向进化技术,对可变盐单胞菌HT7的EPSP合酶基因,荧光假单胞菌G2的EPSP合酶基因以及按植物偏爱密码子合成G2的EPSP合酶基因,进行DNA shuffling,通过EPSP合酶缺陷型菌株E.coil ER2799的功能互补筛选,获得了7个草苷膦抗性有较大变化的EPSP合酶突变体. 相似文献
