基于MTDNA序列的中国臭蚁亚科(膜翅目,蚁科)分子系统学研究

通过对臭蚁亚科7属16种昆虫(凹头臭蚁属philidris因未采集到除模式标本以外的标本,故未包含在其中)线粒体DNA的COⅠ、COⅡ和Cyt b基因部分序列(1 801 bp)进行测定,并从GeneBank下载Leptomyrmex unicolor相应基因片段序列,以江华多刺蚁Polyrhachis jianghuaensis和聚纹双刺猛蚁Diacamma rugosum作外群,重建了中国臭蚁亚科系统发育关系.研究结果支持(狡臭蚁属Technomyrmex+(酸臭蚁属Tapinoma+光胸臭蚁属Liometopum)的关系,虹臭蚁属Iridomyrmex+凹臭蚁属Ochetellus为姐妹群,强烈支持臭蚁属Dolichoderus的单系性,8种臭蚁的遗传关系稳定:((((((平背臭蚁D.flatidorsus+黑腹臭蚁D.taprobanae)+(皱头臭蚁D.rugocapitus+费氏臭蚁D.feae)+双疣臭蚁D.thoracicus)+凹头臭蚁D.incisus)+西伯利亚臭蚁D.sibiricus)+毛臭蚁D.pilosus).系统发育树显示细臭蚁属Leptomyrmex在臭蚁亚科进化过程中的分类地位不确定,没有与同族的虹臭蚁属和凹臭蚁属聚在一起,而是与穴臭蚁属Borhriomyrmex聚在一起互为姐妹群,这与传统的形态分类观点不一致,还有待于进一步研究.

Taxonomic revision of the genus Gynecaptera Skorikov, 1935 from Egypt,with description of a new species (Hymenoptera: Bradynobaenidae,Apterogyninae)

The genus Gynecaptera Skorikov (Bradynobaenidae: Apterogyninae) is revised from Egypt, based on specimens collected from the Sinai Peninsula and those deposited in Egyptian insect collections as well as recorded data from the literature. Three species were previously recorded from Egypt, G. alexandri (Invrea), G. alfierii (Invrea) and G. trimaculata (Skorikov). Gynecaptera sinaitica sp. n. is described here. An illustrated key and a faunistic list comprising all Gynecaptera species recorded from Egypt are also given.

The genus Polyarthra in Lake Peipsi

In Lake Peipsi (Estonia) Polyarthra species often dominate the rotifer community, and are represented by 6 species: Polyarthra dolichoptera Idelson, P. longiremis Carlin, P. luminosa Kutikova, P. major Burckhardt, P. remata Skorikov, P. vulgaris Carlin. The highest diversity occurs in August–September, with P. remata and P. luminosa most abundant. Morphometric data including measurements of body, fins and various types of eggs are given. The seasonal development of the different species and their life cycles are considered.     

Aphids of the genus Dysaphis Börner (Homoptera, Aphididae) living on plants of the family polygonaceae

All morphs of two species of the genus Dysaphis, D. radicola (Mordv.) and D. rumecicola (Hori), living on plants of the family Polygonaceae, are described in detail. Morphometrical analysis has shown that D. radicola meridialis Shaposhnikov, 1964 is merely a synonym of D. radicola radicola (Mordvilko, 1897), and D. albocinerea (Hille Ris Lambers, 1956) and D. rheicola Daniyarova ex Narzikulov et Daniyarova, 1971, synonyms of D. rumecicola (Hori, 1935). D. emicis (Mimeur, 1935) is downgraded to a subspecies of D. rumecicola. Keys to species of the genus Dysaphis living on plants of the family Polygonaceae are provided.     

Dactylostomum cribbi n. sp., a new opecoeline digenean from the Australian freshwater fish Gadopsis marmoratus Richardson

An opecoelid digenean, Dactylostomum cribbi n. sp., is described from the intestine of the freshwater fish Gadopsis marmoratus from Victoria, Australia, and its pathology commented upon. Its systematics is discussed in relation to related opecoelid genera, such as Coitocaecum Nicoll, 1915 (syn. Ozakia Wisniewski, 1933) and Nicolla Wisniewski, 1934, and the species of Dactylostomum Woolcock, 1935 occurring in Australasian waters. D. cribbi is smaller and less elongate than most species of Dactylosto- and Coitocaecum. The zoogeography of this and related forms is commented upon.     

The genus Paradorylaimus Andrássy, 1969 (Dorylaimoidea: Nematoda)

Examination of the type specimens of Dorylaimus parafecundus De Coninck, 1935 showed that the cuticle lacks longitudinal ridges. The species is a typical Laimydorus and is herewith redesignated L. parafecundus (De Coninck, 1935) n.comb. As it is the type species of Paradorylaimus Andrássy, 1969, the latter generic name falls as a synonym of Laimydorus Siddiqi, 1969 which has priority of publication. The three other species included originally in Paradorylaimus are dealt with as follows: P. wilhelmschneideri (Andrássy, 1959) is considered incertae sedis; P. heterurus (Schuurmans Stekhoven & Teunissen, 1938) was shown by Mulk et al. (1978) to belong in the genus Roqueus Thorne, 1964; P. filiformis (Bastian, 1865) is herewith returned to Laimydorus. Dorylaimus tenuistriatus Schneider, 1935 is not identical with L. parafecundus: it is more slender; odontostyle, pharynx and spicules are shorter; supplement number is lower; shape of vulva and the arrangement of the pharyngeal gland nuclei are different. The species is transferred to Laimydorus, becoming L. tenuistriatus (Schneider, 1935) n.comb. Lectotypes are designated for L. parafecundus and L. tenuistriatus. Among the material of L. tenuistriatus are specimens of L. pseudostagnalis (Micoletzky, 1927) and L. sp.     

On the validity of the genusDactylococcopsis (Cyanophyceae)

Summary The genusDactylococcopsis Hansg. 1888 (Cyanophyceae) is based on the typeD. rupestris, which was later identified as a green algae. Most of the many species described later were also placed to other groups of algae. Several authors even doubted about the existence of the genus. As, however, some species of Cyanophyceae correspond to the original generic diagnosis, the name Dactylococcopsis Hansg. ex R. et F.Chod. 1925 has been proposed as a nomen conservandum, and a new type (D. smithii R. et F.Chod.) has been defined. Further speciesD. linearis Geitl. 1935 and D.Planctonica Teil. 1942 has been unambiguously described till now.     

Tracing the introduction history of the brown seaweed Dictyota cyanoloma (Phaeophyceae,Dictyotales) in Europe

Dictyota cyanoloma has recently been described from the Mediterranean Sea and Macaronesia but doubt had arisen as to whether this species was truly native in Europe. The species is mainly found on non-natural substrata (harbour walls, marinas, boat hulls, etc.), strongly suggesting that it is an introduction. Molecular sequence information from historical herbarium samples proves the presence of D. cyanoloma in the Adriatic Sea as early as 1935. Since approximately the year 2000, however, the number of records as well as the geographic range of the species has expanded significantly. The present-day distribution of D. cyanoloma occupies most of the Mediterranean Sea, Macaronesia, NW Africa and southern Portugal, but recent records from Galicia and SW England (Falmouth, Cornwall) indicate that the species is rapidly expanding northward. Collections from Australia demonstrated that the species is also present from Perth in Western Australia, over much of the southern Australian coastline up to Minnie Water in New South Wales. Phylogenetic analyses resolve D. cyanoloma in a sister clade to a previously unreported Australian Dictyota species. Analysis of genetic diversity of the mitochondrial markers (nad6–nad11 and atp9–orf11) reveals that even though Australian populations contain a much higher haplotype richness, European populations are also fairly diverse. Furthermore, only two out of 25 haplotypes are shared between both regions. These somewhat counterintuitive results could be indicative of a more complicated introduction history.     

A review of genus Grahamomyia Alexander, 1935 (Diptera,Limoniidae)

Only one species of the genus Grahamomyia Alexander, 1935 was previously known from the world. Here one new species, Grahamomyia bilobula sp. nov., is reported from China. Grahamomyia bicellula Alexander, 1935 is re-described and illustrated. A key to the known species of Grahamomyia is presented.LSID: urn:lsid:zoobank.org:pub:A18E32D8-B017-46FF-B05B-B664AF988F1B.     

Synonymy and actual affinities of the putative Middle Eocene “New World vulture” Eocathartes Lambrecht , 1935 and “hornbill” Geiseloceros Lambrecht , 1935 (Aves, Ameghinornithidae)

The taxonomy and phylogenetic affinities of the putative “New World vulture”Eocathartes robustus,Lambrecht, 1935 and the “hornbill”Geiseloceros robustus Lambrecht, 1935 from the Middle Eocene of the Geisel Valley in Germany are revised. It is shown that the holotype specimens belong to a single individual, whose osteology closely resembles that ofStrigogyps sapea (Peters, 1987) from the Middle Eocene of Messel (Germany). The species is classified intoStrigogyps robustus (Lambrecht, 1935), n. comb., and provides further evidence for the great similarity between the Eocene avifaunas of the Geisel Valley and Messel.Strigogyps is a representative of the Ameghinornithidae whose phylogenetic affinities are uncertain; there is no fossil record of either Cathartidae (New World vultures) or Bucerotidae (hornbills) from the Geisel Valley.
