As espécies são registradas para o Norte da América do Sul: Bolívia, Brasil, Colômbia, Guiana, Guiana Francesa, Peru e Suriname. Neste estudo foram analisados 149 exemplares provenientes de quatro instituições. As quatro espécies válidas foram redescritas, a identidade de P. cardinalis definida, uma vez que a mesma era conhecida apenas pelo seu lectótipo e este não possui abdômen. Foram propostas três novas espécies, todas com ocorrência no Norte do Brasil, ampliando dessa forma o conceito do gênero, através de novos caracteres, principalmente, da genitália dos machos. Além disso, as descrições incluem estudos das estruturas do ovipositor das fêmeas, que demonstrou ser um bom diagnóstico para identificação do gênero, principalmente, a forma do esternito VII. É apresentada uma chave para identificação das espécies. PALAVRA CHAVE: Cicadellinae, Distribuição, Taxonomia. / Abstract: Poeciloscarta Stål (1869) comprises four known species: Poeciloscarta cardinalis (Fabricius, 1803) type species, P. extricans (Walker, 1858), P. aurorula (Breddin, 1901) and P. mielkei, Cavichioli, 1989. The species are recorded form north of South America: Bolivia, Brazil, Colombia, Guyana, French Guyana, Peru and Suriname. In this study were observed 149 specimens from four institutions. All previously described species were redescribed, the identity of P. Cardinalis is defined since its Lectotype lack abdomen. Three new species have been proposed, all occurring in northern Brazil, the concept of Poeciloscarta was expanded and new characters are added, especially about the male genitalia. The descriptions includes structures of female ovipositor, which proved to be good diagnosis caracter for identification of Poeciloscarta, especially the shape of the sternite VII. A key to species is present. KEY WORD: Cicadellinae, distribution, taxonomy.

The southern African species of the Aradidae subfamily Carventinae are revised, resuhing in the recognition of 7 genera, 24 species and 10 subspecies (excluding the nominal ones). Of these, 4 genera, 18 species and 10 subspecies are described as new. A neotype is designated for Dundocoris natalensis. Keys to the genera and species are given. Scanning electron photomicrographs of the dorsal and ventral aspects and external genitalia are provided for all the species. The cytogenetics of the group are discussed and idiograrns, based on chromosome area measurements, and photomicrographs of meiotic stadia (mostly metaphase I and metaphase II) are presented for all but one species. The chromosome numbers of the species vary between 2n = 7XY1Y2 and 2n = 32XY and XY, X1X2Y and XY1Y2 sex chromosome systems occur. Muhiple sex chromosome systems that originated from autosome-sex chromosome fusions are described for the first time in the Heteroptera. A unique case where two homologous autosomes have fused with the X- and Y -chromosomes respectively, is reported. Karyotype evolution and the origin of the different chromosome numbers are discussed and hypotheses presented. Pseudoploidy, fusions and to a lesser extent fragmentation, have played the major role in the karyotype evolution of the Carventinae. The cytogenetics of the other subfamilies of the Aradidae are briefly discussed and illustrated. It is argued that the ancestral chromosome number for the Carventinae and Aradidae (and therefore also the Pentatomorpha) is 2n = 14XY. The morphological and cytogenetic data are integrated in the classification of the Carventinae and several of the subspecies are based on chromosome number differences. The homeostatic genetic species concept is proposed and its application to the Carventinae is discussed. Phylogenies for the genera and species are proposed. The text is accompanied by more than 540 figures and more than 60 tables. / Thesis (DPhil (Entomology))--University of Pretoria, 2007. / Zoology and Entomology / unrestricted

There are some references on the study of morphology of the Homoptera in which Cicada has been taken as a basis for the generalised structure. In the sub-order Sternorhyncha paylla has been studied, but there are hardly any references directly dealing with the Aleurodidae or any particular species except the general morphological and anatomical features described by Quaintance and Baker (l913) in their "Classification of the Aleurodidae, Part I.". No one has studied the structure of any of the British species.

A thesis submitted to the Faculty of Science, University of the Witwatersrand, Johannesburg, in fulfilment of the requirements for the degree of Doctor of Philosophy. Johannesburg, 2014. / Entomophagy, the consumption of insects, has attracted interest as a low input minilivestock with good nutritional value. The inflated stinkbug, Encosternum delegorguei, is an appetizing food, a hangover cure and a trade item in South Africa, Malawi and Zimbabwe yet very little is known about it. This study comprehensively integrates plant aspects (food and shelter) and insect biology (distribution, life cycle and fecundity) with socio-economic and conservation aspects. Firstly, E. delegorguei was observed in outdoor insectaries where it exhibited reproductive winter diapause and declining abdominal fat content attributed to non-feeding. In spring (September) E. delegorguei fed on Combretum imberbe, Combretum molle (Combretaceae), Peltophorum africanum (Fabaceae), and to a lesser degree on Dodonaea viscosa (Sapindaceae) and the grass Pennisetum clandestinum (Poaceae). Copulation occurred during October/November but eclosion was reduced by the egg parasitoid wasp, Anastatus sp. Secondly, structured interview schedules with 106 harvesters indicated that an estimated total of 3803 + 43.4 kg (mean+S.E.) dry stinkbugs was harvested with an annual gross per capita income of =US$ 345. In South Africa stinkbugs are consumed by two locally separate ethnic groups the Vhavenda and Mapulana, with a third group, the Bolobedu selling them. Ethnic differences in nomenclature and oral history, methods of collection and preparation, as well as perceptions pertaining to availability were documented between the three groups. Damage to host trees occurred when harvesters poached from pine plantations or private land, whereas, in communal-lands, sustainable methods proliferated. Using a regional maximum entropy modelling method (MAXENT) on winter locations of E. delegorguei known to harvesters, current and future distribution scenarios were identified. Winter precipitation and to a lesser degree summer precipitation and winter temperature were key climatic variables limiting the regional distribution of E. delegorguei. Moreover, potential new sites unknown to harvesters or areas where minilivestock initiatives could be piloted have been highlighted for further investigation. Opportunities to reduce impediments to collection and trade are discussed in a sustainable framework. For example legitimisation of harvesting and introduction of a collection funnel to reduce conflicts with plantation, orchard and private land managers. Awareness and optimal use of beneficial bio-resources, such as E. delegorguei, could encourage community driven habitat stewardship.
