The genus has characters of both the tribes Mesargini and Coloborrhinini, suggesting that the delimitation of these tribes may not be natural. The tribal placement of Ulopsina is uncertain. A checklist of the subfamily Ulopinae from China is also provided, and nine Chinese species designated under the genus Moonia are herein transferred to Mesargus, namely Mesargus albomaculata (Li) comb. nov., M. brevita (Cai et Shen) comb. nov., M. castanea (Kuoh) comb. nov., M. hei (Cai et Shen) comb. nov., M. hirsuta (Li) comb. nov., M. hyboma (Cai et Kuoh) comb. nov., M. maculigena (Kuoh) comb. nov., M. serrata (Li and Zhang) comb. nov., and M. spinapenis (Li and Zhang) comb. nov.

TREWICK defining feature of the Hexapoda, as the name suggests, is six legs. Also, the body comprises a head, thorax, and abdomen. The number A of abdominal segments varies, however; there are only six in the Collembola (springtails), 9–12 in the Protura, and 10 in the Diplura, whereas in all other hexapods there are strictly 11. Insects are now regarded as comprising only those hexapods with 11 abdominal segments. Whereas crustaceans are the dominant group of arthropods in the sea, hexapods prevail on land, in numbers and biomass. Altogether, the Hexapoda constitutes the most diverse group of animals – the estimated number of described species worldwide is just over 900,000, with the beetles (order Coleoptera) comprising more than a third of these. Today, the Hexapoda is considered to contain four classes – the Insecta, and the Protura, Collembola, and Diplura. The latter three classes were formerly allied with the insect orders Archaeognatha (jumping bristletails) and Thysanura (silverfish) as the insect subclass Apterygota (‘wingless’). The Apterygota is now regarded as an artificial assemblage (Bitsch & Bitsch 2000).

Hemiptera, Membracoidea, Cicadellidae, Cicadoidea, Cercopoidea, Fulgoroidea, head, morphology, ground plan Abstract. The ground plan and comparative morphology of the nymphal head of Membracoidea are presented with particular emphasis on the position of the clypeus, frons, epistomal suture, and ecdysial line. Differences in interpretation of the head structures in Auchenorrhyncha are discussed. Membracoidea head may vary more extensively than heads in any other group of insects. It is often modified by the development of an anterior carina, which apparently was gained and lost multiple times within Membracoidea. The main modifications of the head of Membracoidea and comparison of those changes with the head of other superfamilies of Auchenorrhyncha are described. INTRODUCTION MATERIAL AND METHODS The general morphology of the insect head is relatively Dried and pinned specimens were studied under an Olympus well studied (Ferris, 1942, 1943, 1944; Cook, 1944; SZX12 microscope with SZX-DA drawing tube attachment.

  • Evolutionary Drivers of Temporal and Spatial Host Use Patterns in Restio Leafhoppers Cephalelini (Cicadellidae)
    Evolutionary drivers of temporal and spatial host use patterns in restio leafhoppers Cephalelini (Cicadellidae) By Willem Johannes Augustyn Thesis presented in fulfilment of the requirements for the degree of Doctor of Philosophy in the Faculty of Science at Stellenbosch University Promoters: Allan George Ellis and Bruce Anderson December 2015 1 Stellenbosch University https://scholar.sun.ac.za Declaration By submitting this thesis/dissertation electronically, I declare that the entirety of the work contained therein is my own, original work, that I am the sole author thereof (save to the extent explicitly otherwise stated), that reproduction and publication thereof by Stellenbosch University will not infringe any third party rights and that I have not previously in its entirety or in part submitted it for obtaining any qualification. Copyright © 2015 Stellenbosch University All rights reserved 2 Stellenbosch University https://scholar.sun.ac.za Abstract Understanding how divergent selection results in the evolution of reproductive isolation (i.e. speciation) is an important goal in evolutionary biology. Populations of herbivorous insects using different host plant species can experience divergent selection from multiple selective pressures which can rapidly lead to speciation. Restio leafhoppers are a group of herbivorous insect species occurring within the Cape Floristic Region (CFR) of South Africa. They are specialised on different plant species in the Restionaceae family. Throughout my thesis I investigated how bottom- up (i.e. plant chemistry/morphology of host plant species) and top-down (i.e. predation and competition) factors drive specialisation and divergence in restio leafhoppers. I also investigated interspecific competition as an important determinant of restio leafhopper community structure.

  • The Leafhopper Genus Tiaja Oman (Homoptera: Cicadellidae), with a Contribution to The
    AN ABSTRACT OF THE THESIS OF Jane Rosamund Sawbridge for the degree ofDoctor of Philosophy in Entomology presented onAugust 12, 1976 Title: THE LEAFHOPPER GENUS TIAJA OMAN (HOMOPTERA: CICADELLIDAE), WITH A CONTRIBUTION TO THE BIOSYSTEMATICS OF THE GROUP Redacted for privacy Abstract approved: Paul Oman The genus Tiaja Oman consists of eight known species of flight- less leafhoppers of the subfamily Megophthalminae found along the western coast of North America between British Columbia and northern Mexico. Species occurring from the San Francisco Bay area northward are restricted to a narrow coastal zonewithin 1 km of the ocean; some of those species that occur farther south may be found inland as well as on the coast. Members of the genus occupy an unusual habitat in that most individuals arefound on the undersides of their host plants or in the litter layer beneath them.Flightlessness and the position the insects occupy on their host plants are seen as adaptations to enhance survival in a windswept environment. Life history studies of T. friscana (Ball) and T. arenaria Oman show that nymphs normally pass through five nymphal ins tars although some individuals may have four or six nymphal ins tars.The final nymphal ins tar is of longer duration than any of the preceding ins tars but the length of the developmental period appears to depend on temperature conditions in the rearing chamber. The northern- most species, T. arenaria, is univoltine with obligatory diapause while T. friscana and T. montara Oman, two species of the central California coast, are multivoltine with no diapause under favorable conditions.Other species are presumed to be multivoltine.

Like many of the other insect families the Cicadellidae, with reference to their occurrence in the South African Sub-Region, have received very little attention from entomological workers. Their small size and pre­ dominantly inconspicuous colouration probably account for their escape from the attention of collectors and naturalists at large, while the slow development of the country has precluded the possibility of economic importance equalling that of members of this family occurring in parts of the world, where agriculture has reached a more intensive stage of development. The work done on the South African forms so far com­ prises mainly the publications of Stal, Walker, Distant and Cogan. Of the two former, Stal's work is the most extensive. His " Hemiptera Africana," which was written as early as 1855 and is, even in our day, the foundation of, and the most important reference on, South African Hemiptera, constitutes only a small part of his work on the Hemiptera, and especially the Homoptera, of the world.
