Revision of the genus Australimyza Harrison (Diptera: Australimyzidae)

Abstract.  The species of Australimyza Harrison are revised and the saprophagous larvae are described for the first time. The phylogenetic analysis revealed two species groups and one ungrouped species. One species group is distributed in New Zealand and associated subantarctic islands; all other species occur in Australia. Four new species, A. glandulifera , A. kaikoura , A. mcalpinei and A. victoria , are described, A. anisotomae is synonymized with A. australensis and a neotype is designated for the latter species. A lectotype is designated for A. macquariensis .

Phylogeny and distribution of the phoracanthine genus Atesta (Coleoptera: Cerambycidae) from Australia

The phylogeny of the phoracanthine genus Atesta (thirty-four species) is analysed using cladistic methods. The monophyly of Atesta is confirmed. Three major monophyletic species groups are recognized: (1) the thorntoni -group including twelve species: A.thorntoni, A.balteata, A.latifasciata, A.mediana, A.patula, A.newi, A.angasi, A.bifasciata, A.besti, A.ciliata, A.paratasmanica and A.tasmanica ; (2) the sisyrioides -group consisting of seventeen species: A.ibidionoides, A.carteri, A.longoelytrata, A.pubescens, A.stigmosa, A.sita, A.vittata, A.sparsa, A.minuta, A.tropicalis, A.unifasciata, A.sisyrioides, A.nigrihumerus, A.apicalis, A.brittoni, A.antennalis and A.brooksi , and (3) the houstoni -group containing five species: A.mapida, A.houstoni, A.tripartita, A.dixoni and A.centroaustralica. The distribution patterns of Atesta are described and discussed. Five distinct areas of endemism are found for Atesta: the Torresian, Timorian, Kosciuskan, Western and Eyrean Subregions. The Torresian Subregion has nine species, three of which are endemic to the subregion; the Timorian has four species, two of which are endemic; the Kosciuskan has twenty-three species, sixteen of which are endemic, the Western has five species, four of which are endemic, and the Eyrean has three species, one of which is endemic. Two kinds of distribution patterns for Atesta are identified: the wet adapted (peripherial), including the thorntoni -group and sisyrioides -group, and the wide-adapted, consisting of the houstoni -group. The thorntoni -group is typically a southern Australian species group, distributed in south-eastern and south-western Australian continent and Tasmania. The sisyrioides -group is mainly distributed in southeastern, eastern and northern Australian continent and Tasmania. The distribution of the houstoni -group includes central and peripherial Australian continent.

The taxonomy and distribution of Azolla species in southern Africa

The three Azolla species which occur in southern Africa, A. pinnata var. pinnata, A. nilotica and A. filiculoides are identified and their distributions illustrated. The endosymbiotic cyanobacterium Anabaena azollae occurred in dorsal leaf lobe cavities of all three species. The first two species are indigenous to southern Africa, whilst the third, A. filiculoides , is an introduced species from North America. Possible means whereby this species could have been introduced are discussed.     

葱属根茎组8种21居群植物的核型研究

对葱属根茎组Allium sect.Rhiziridium的8种21个地方居群的核型进行研究,以期为解决该组的种间亲缘关系和物种进化机制提供依据。贺兰韭A.eduardii和阿拉善韭A．flavovirens2个种的核型以及辉韭A．strictum的六倍体核型均属首次报道。研究结果表明：贺兰韭A.eduardii、阿拉善韭A.tlavovirens、北韭A.lineare、蒙古韭A.mongolicum和滩地韭A．oreoprasum的各居群均为二倍体,核型类型为Stebbins的2A型;韭A．tuberosum和野韭A.ramosum的各个居群均为四倍体,核型类型为2A型：辉韭A．Jtrictum的4个居群均为六倍体,核型类型为2B型。通过研究可以得出如下推论：（1）该组植物中存在着大量的多倍体或多倍体系列,染色体数目变化与物种进化具有密切相关性,多倍化可能是根茎组植物核型进化的重要机制之一;（2）随体染色体多为st或t染色体,均位于短臂末端;（3）可以认为辉韭是以增加倍性来克服该物种扩大新的生存空间所带来的困难;（4）现今栽培的韭可能是由野生的二倍体韭和四倍体韭经过长期人工驯化而来的,现今栽培的三倍体韭可能是二倍体韭和四倍体韭杂交而来,并且以无性繁殖方式保存三倍体类群的存在。

Abstract  The Egyptian species of the aphelinid genus Aphytis Howard are reviewed. Aphytis azai Abd-Rabou and Aphytis matruhi Abd-Rabou are described as new species from Egypt. Each species is briefly diagnosed and known information on hosts and distributed is given. A. azai sp. nov. is similar to A. melinus but different in the measurement of antennal segments. A. matruhi sp. nov. differs from A. lepidosaphes by the relative length of propodeum, metanotum and scutellum. A key to the Egyptian species of Aphytis is provided.     

A revision of the genus Annesorhiza (Apiaceae)

The genus Annesorhiza is revised and twelve species are recognized, of which two are newly described: A. altiscapa, A. burttii, A. flbrosa, A. flagellifolia, A. grandiflora, A. lateriflora, A. latifolia, A. macrocarpa, A. nuda, A. schlechteri, A. thunbergii and A. wilmsii. A. marlothii is reduced to synonymy under A. lateriflora , a species hitherto poorly known as Peucedanum lateriflorum. A. thunbergii is only known from the type specimen. A. elata, A. hirsuta and A. villosa are sunk under A. grandiflora. A. fúicaulis has recently been excluded from Annesorhiza on the basis of fruit structure. A key to the species is provided, an update on the nomenclature, typification of names and distribution maps are provided for all the species.
