The taxonomic value of the notopleural cleft in Phoridae is highlighted. A cladogram relating Gymnophora and Woodiphora to Megaselia is presented. Recognition of the genus Woodiphora is clarified, and the Old World species of Haplophleba transferred to Woodiphora. The evolution of the female abdominal sternite 9 is discussed. The tribe Megaseliini is proposed. A key to the Australasian and Oriental species of Woodiphora is provided. Twenty new species are described and two new synonyms proposed.  相似文献

中国岩黄耆属(Hedysarum L.)植物区系生态地理分布   总被引:1,自引:0,他引:1  
依据种的现代分布、替代关系、地质历史、古气候和化石资料,探讨了中国岩黄耆属植物区系的发生、演变及形成机制.结果表明:岩黄耆属可能是由古地中海旱生植物区系中一类中生的原始灌木类群,在晚始新世到早渐新世或比这个时期稍晚一些,经过第三纪以来的环境分异变化,逐渐形成适应高寒山地生长的扁荚组种类和适应干旱环境生长的多茎组、短茎组种类,短茎组种类是多茎组对干旱强化进一步适应的结果,与此同时,原始的灌木类群自身也在继续演化,形成适应荒漠半荒漠生长的种类.这种演化过程揭示出生存环境中水热条件的剧烈变化是植物演化的主要动力.  相似文献

The predominantly marine genus Schizopera Sars, 1905 has only two significant inland water species-flocks, one in the ancient African Lake Tanganyika and the other in subterranean waters of Western Australia. Discovery of Schizopera abei sp. nov. from several interstitial locations in the vicinity of the ancient Lake Biwa has wider implications for the study of morphological homoplasies in the genus, as well as for the study of freshwater invasions in harpacticoid copepods. The new Schizopera species belongs to a small group of congeners with a two-segmented endopod of the fourth leg, which used to be recognised as a separate genus, Schizoperopsis Apostolov, 1982. Our reconstructed phylogenies based on the mtCOI partial sequences suggest that this character probably evolved convergently in at least some Schizopera, thus rendering the genus Schizoperopsis polyphyletic. However, almost all basal nodes in our cladograms are weakly supported, which shows limitations of a single-gene approach for reconstructing phylogenetic relationships. The new species is the first member of its genus from Japanese inland waters, and it has no close relatives among extent congeners anywhere in the world. We speculate that its ancestor may have invaded Lake Biwa, and subsequently its surrounding subterranean waters, from brackish areas around central Japan, presumably during a period of high sea water level through its major outflow river. This discovery may provide further support for the hypothesis about the role of ancient lakes as biodiversity pumps for subterranean habitats.

The ichneumonid wasp genera Skiapus Morley, Hellwigia Gravenhorst, Nonnus Cresson, Chriodes Förster, and Klutiana Betrem are each formally removed from the Campopleginae on the basis of morphological, molecular, and simultaneous analyses using PAUP* and the optimization alignment program POY. Skiapus and Hellwigia are shown to form a monophyletic group with the Ophioninae to which they are transferred. Nonnus is treated as comprising the Nonninae stat. nov. and Chriodes and Klutiana (sometimes treated as a junior synonym of Chriodes) are treated as comprising the Nesomesochorinae stat. rev. The status of Nesomesochorinae and Nonninae is not fully resolved as they are not consistently recovered as separate groups, forming a single clade in some analyses. We keep them separate because of this uncertainty. Molecular synapomorphies within the D2–3 expansion region of the 28S rDNA gene show the utility of this gene region in determining subfamily‐level placement within the higher Ophioniformes.  相似文献

The monotypic centipede genus Prionopodella Verhoeff, 1925 Verhoeff, K. W. 1925. Results of Dr. E. Mjöberg's Swedish scientific expeditions to Australia 1910–1913. 39. Chilopoda.. Arkiv för Zoologi, 26A: 162.  [Google Scholar] has until now been known only from the types of its type species, collected in Queensland, Australia, nearly a century ago. The female gonopods of Prionopodella were described as having a uniquely tripartite structure, viewed as primitive relative to the bipartite gonopod of all other Scutigeromorpha. An articulation in the syntelopodite is present in one syntype, but new specimens from central eastern Queensland show an, at most, incompletely jointed or entirely unjointed syntelopodite, as in other scutigeromorphs. Cladistic analysis of morphological characters including Prionopodella and the likewise monotypic Australian genus Prothereua Verhoeff, 1925 Verhoeff, K. W. 1925. Results of Dr. E. Mjöberg's Swedish scientific expeditions to Australia 1910–1913. 39. Chilopoda.. Arkiv för Zoologi, 26A: 162.  [Google Scholar], shows Prionopodella to nest within Thereuoneminae, allied to other Asian/Australian genera, rather than in a basal position within Scutigeromorpha as is implied by Verhoeff's theory about primitive gonopod structure.  相似文献

Worldwide knowledge of tardigrade fauna is still limited, and many areas such as South America are not well studied. The collection of new substrates in Argentinean urban areas provided an opportunity to describe the new tardigrade species Macrobiotus kristenseni sp. nov. This species has been studied with an integrative taxonomic approach, analysing its morphology by light and scanning electron microscopy, and considering two genes (cox1 and 18S rRNA) for DNA barcoding and phylogenetic purposes. The species belongs to the Macrobiotus hufelandi group of species, and it is characterized by egg processes in the shape of elongated cones with truncated and enlarged apexes, and by a high genetic distance with respect to closely related species (cox1: 18.2–33.4%). Morphological and molecular data show that the Macrobiotus hufelandi group of species has to be considered a true biological entity; one of the more widespread tardigrade lineages in continental environments. http://www.zoobank.org/urn:lsid:zoobank.org:pub:2CA51ABA-5570-4AFB-8182-CE499D97B0F1  相似文献

Differentiation of external morphology of Oribatella Banks, 1895 was investigated, in light of the ontogeny of Oquadricornuta (Michael, 1880 Michael, AD. 1880. A further contribution to the knowledge of British Oribatidae. J Roy Micr Soc London, 3: 225251. [Crossref] [Google Scholar]), Osuperbula (Berlese,1904 Berlese, A. 1904. Acari nuovi. Manipulus III. Redia, 2: 1032.  [Google Scholar]) and O. calcarata (CL Koch, 1835 Koch, CL. 1835. “Deutschlands Crustaceen, Myriapoden und Arachniden”. In Regensburg, Germany: Verlag Friedrich Pustet 13.  [Google Scholar]) studied here for the first time, and that of the other species from the literature. The pattern of gastronotal setae in larvae is similar, except for lack of seta h 3 in Onortoni Behan-Pelletier, 2011 Behan-Pelletier, VM. 2011. Oribatella (Acari, Oribatida, Oribatellidae) of eastern North America. Zootaxa, 2973: 156. [Crossref] [Google Scholar], while that of nymphs and adults is differentiated. The nymphs of most species have 15 pairs of gastronotal setae, but those of Ometzi Behan-Pelletier, 2011 Behan-Pelletier, VM. 2011. Oribatella (Acari, Oribatida, Oribatellidae) of eastern North America. Zootaxa, 2973: 156. [Crossref] [Google Scholar] and most nymphs of Ocalcarata have 13 pairs. The nymphs of most species carry the exuvial scalps of previous instars on apical parts of gastronotal setae da, while setae dm and dp, located under these scalps, are subjected to translocation, reduction in size or loss. In Oberlesei (Michael, 1898 Michael, AD. 1898. “Oribatidae”. In Das Tierreich, Lief. 3. Vol. 8 (Acarina). Berlin: Verlag von R. Friedländer und Sohn Edited by: Schulze, FE. 193. [Crossref] [Google Scholar]), Onortoni, Oquadricornuta and Osexdentata Berlese, 1916 pair dp takes a more lateral position, compared with the larvae, in Osuperbula and Ocanadensis Behan-Pelletier and Eamer, 2010 Behan-Pelletier, VM and Eamer, B. 2010.

[Crossref] [Google Scholar] it is reduced in size (in the latter species pair dm is also reduced), while Ometzi loses setae dm and dp. In contrast, the nymphs of Ocalcarata do not carry the scalps, and usually lose setae c 1 and dm. The adults of all species lose setae c 1, c 3 and d-series, compared with the tritonymph, and only 10 pairs of notogastral setae remain (c 2, l-, h- and p-series), but Oquadricornuta and Ocalcarata rarely retain seta c 3 unilaterally, which indicates the order of setal loss in Oribatella according to Shaldybina (1972 Shaldybina, ES. 1972. Some morphological characters of ceratozetid moss mites (Oribatei). Ucenyje zapiski Gor Gosud Pedagog Institut, Gorki, 130: 3566. In Russian [Google Scholar]).  相似文献

Proserpinicaris young sp. nov., Proserpinicaris wangpi sp. nov. and Proserpinicaris imjin sp. nov. are described from subterranean waters of South Korea. They are short-range endemics, allopatric in distribution and closely related to each other, and to two other Far Eastern congeners. Distinguishing features are limited to the general habitus shape, proportions of the caudal rami and degree of sexual dimorphism. The genus Proserpinicaris Jakobi, 1972 Jakobi, H. 1972.
