Udinia, an Ethiopian coccid genus, is redefined and a key is given to the thirteen species now recognised: bruncki sp. n. , catori (Green) comb. n. [= Lecanium subhirsutum Newstead syn. n. ], farquharsoni (Newstead) [= U.exoleta (De Lotto) syn. n. ], glabra De Lotto, ikoyensis sp. n. , lobayana (Balachowsky & Ferrero) comb. n. , newsteadi sp. n. , nigeriensis sp. n. , pattersoni sp. n. , paupercula De Lotto, pterolobina De Lotto, scitula De Lotto, setigera (Newstead). Five species are described as new and three species are redescribed and for these lectotypes are designated. The morphological characters used are discussed and listed and intraspecific variations shown by two of the species are tabulated. The distribution of all the species is recorded on two maps and the literature dealing with associations between ants and Udinia and related coccid genera is briefly reviewed.  相似文献

Abstract. 1. The Mediterranean black scale Saissetia oleae (Olivier) was the most suitable host for the imported Metaphycus aff. stanleyi Compere and Metaphycus helvolus (Compere) and for the local Metaphycus flavus (Howard). 2. Difficulties were encountered in the mass rearing of the introduced parasitoids, particularly M. aff. stanleyi, on the hemispherical scale Saissetia coffeae (Walker) and on the brown soft scale Coccus hesperidum L., because many of the eggs were encapsulated. 3. Although all the eggs of M.aff.stanleyi were encapsulated shortly after being deposited in S.coffeae, some larvae developed, broke out of the capsule and developed normally. 4. The incidence of parasitized scales containing only encapsulated eggs of any of the three Metaphycus species, increased with the stage of the host.  相似文献

Abstract. Eriopeltis varleyi from Wytham in Britain is described as new. The adult female and male are described and all stages are illustrated. Keys are provided for the identification of all known species of Eriopeltis, and to the males of the three species known from Britain. E. varleyi is univoltine and apparently specific to Brachypodiumpinnatum (L.) Beauv. Males and females occur in equal proportions, but many more males were produced when populations were reared under very warm dry conditions in the laboratory. The population studied at Wytham was parasitized by a number of species of chalcid wasps and a chamaemyid fly egg predator.  相似文献

Abstract. The mealybug Trabutina mannipara (Hemprich & Ehrenberg, 1829) is described and illustrated, and a neotype female selected from topotypic material collected in the Sinai Peninsula. A lectotype female is designated for Trabutina palestina Bodenheimer (1927) which is shown to be a junior synonym of T.mannipara.  相似文献

Ceroplastes Gray (wax scales) is one of the genera of Coccidae, most species of which are considered to be serious economic pests. However, identification of Ceroplastes species is always difficult owing to the shortage of easily distinguishable morphological characters. Mitochondrial cytochrome c oxidase I (COI) sequences (or DNA barcodes) and the D2 expansion segments of the large subunit ribosomal RNA gene 28S were used for accurate identification of six Ceroplastes species (C. floridensis Comstock, C. japonicus Green, C. ceriferus (Fabricius), C. pseudoceriferus Green, C. rubens Maskell and C. kunmingensis Tang et Xie) from 20 different locations in China. For COI data, low G·C content was found in all species, averaging about 20.4%. Sequence divergences (K2P) between congeneric species averaged 12.19%, while intra‐specific divergences averaged 0.42%. All 112 samples fell into six reciprocally monophyletic clades in the COI neighbour‐joining (NJ) tree. The NJ tree inferred from 28S showed almost same results, but samples of two closely related species, C. ceriferus and C. pseudoceriferus, were clustered together. This research indicates that the standard barcode region of COI can efficiently identify similar Ceroplastes species. This study provides an example of the usefulness of barcoding for Ceroplastes identification.  相似文献

Abstract The type-species of four genera of Pseudococcidae are studied. Fonscolombia Lichtenstein is redefined, the type-species, Fonscolombia graminis Lichtenstein is assigned to the Pseudococcidae, redescribed and a lectotype designated. Laboulbenia Lichtenstein is accepted as an objective synonym of Antonina Signoret. Tetrura Lichtenstein ( non : Lesson) is accepted as an objective synonym of Coccura Sulc. The adult female of the material of this species which Lichtenstein misidentified as Tetrura rubi (Schrank) is redescribed and illustrated. Brevennia Goux is redefined, and the type-species Ripersia (Brevennia) tetrapora Goux redescribed. The characteristics of Asphodelococcus Morrison are discussed, the type-species Ripersia asphodeli Bodenheimer redescribed and a neotype designated; A.meoconcitae Tranfaglia & Marotta is a new synonym of A. asphodeli .  相似文献

The genus Leptopulvinaria Kanda is revised and placed in the tribe Pulvinariini as understood by Hodgson. The species L. kawaii sp. nov., which has been misidentified as Pulvinaria camelicola or P. floccifera by several researchers, is recognized as a second species of the genus, in addition to the type species L. elaeocarpi Kanda. Adult females of L. elaeocarpi and L. kawaii are redescribed and a key to the species is presented.  相似文献

The form of the female ovipositor and chaetotaxy of the fifth instar nymphs have been found to distinguish the two European Iassus species, lanio (L.) and scutellaris (Fieber). The latter species is recorded in Britain for the first time.  相似文献

Soil samples and museum collections were analysed from all zoogeographic regions of the world. From this material eleven new species of Ortheziola?ulc are described from Africa and the U.K., five additional species are redescribed and a key is presented for the identification of all sixteen species. A slightly modified concept of the genus is presented and several new characters are given as diagnostic of the genus. A phylogenetic hypothesis is given based on analysis of the morphological features of adult females. Results show that Ortheziola is most diverse in eastern Africa where relatively more advanced species occur. Basal species occur primarily in western Africa and Asia.  相似文献

Seven genera of wax scales (Ceroplastinae) have been accepted as valid by some or all coecidologists: Ceroplastes Gray, Ceroplastidia Cockerell, Cerostegia De Lotto, Gascardia Targioni Tozzetti, Paracerostegia Tang, Vinsonia Signoret and Waxiella De Lotto. The status of most these genera is controversial. The present study reviews the taxonomic history of wax scales and presents a new classification based on cladistic analysis of morphological data from the adult females of eighty-three species. The analysis indicates that the wax scales form a monophyletic group, that Waxiella is monophyletic but that Ceroplastidia, Gascardia and Vinsonia are not, and fails to support the generic status of Cerostegia and Paracerostegia. Apart from the type species of Vinsonia , which was placed as a sister to the rest of wax scales, the only other species assigned to Vinsonia and most species of all other genera fall within Ceroplastes in the cladogram. Recognition of any of these genera renders Ceroplastes paraphyletic or polyphyletic. Thus, cladistically, the wax scales should be classified into one genus, Ceroplastes.  相似文献
