Abstract. From a study of P.castilloae (Cockerell), the type species of Platysaissetia Cockerell, it is considered that none of the other species presently placed in Platysaissetia are congeneric. All known species from Africa (and one from British Guiana) are redescribed and are here transferred to the genus Etiennea Matile-Ferrero; one species is synonymized and twelve species are described as new. Lectotypes have been designated for Etiennea kellyi (Brain) and E.montrichardiae (Newstead). Although not considered to be congeneric with P.castilloae, P.tsaratananae Mamet and P.crustuliforme (Green) are left in Platysaissetia.  相似文献

Abstract. The subfamily Cercobarconinae is synonymized with the Trachypetinae, the constituent genera ( Trachypetus Guérin de Méneville, Megalohelcon Turner and Cercobarcon Tobias) are rediagnosed and the species are revised and redescribed. Rhamphobarcon Tobias is synonymized with Megalohelcon Turner, R.mosaicus Tobias is synonymized with M.torresensis Turner, M.uptoni Tobias is synonymized with M.ichneumonoides Tobias, and four species are newly described: M.mouldsi, C.bilobatus, C.grossi and C.niger. Relationships within the subfamily are discussed, as are those of the Trachypetinae to other braconid subfamilies. Comments on the biology and distribution of species are provided, along with an illustrated key to genera and species.  相似文献

Abstract The scale insect tribe Iceryini (Coccoidea: Monophlebidae) is a group of relatively large and polyphagous insects found worldwide. Currently, the tribe contains about 80 named species placed in seven genera, which are diagnosed largely on features associated with egg protection. We reconstruct the phylogeny of the Iceryini on the basis of nucleotide sequence data from nuclear ribosomal (18S and D2, D3 and D10 regions of 28S) and protein‐coding (histone H3) gene regions of 40 iceryine species representing six of the seven genera and seven outgroup taxa, mostly from two other tribes of Monophlebidae. Bayesian and maximum parsimony analyses recover a monophyletic tribe and clades that correspond more to geography than to the existing morphology‐based classification. Gueriniella Fernald is sister to the rest of the Iceryini and the genera Crypticerya Cockerell, Icerya Signoret and Steatococcus Ferris are not monophyletic. Our data imply that the distinctive iceryine reproductive strategies, such as protecting eggs in a waxy ovisac or inside a marsupium, are poor indicators of relationships. On the basis of molecular relationships and the re‐examination of morphological characters, we recognize only five genera of Iceryini –Crypticerya, Echinicerya Morrison, Gigantococcus Pesson & Bielenin, Gueriniella and Icerya – and substantially revise the generic concepts of Crypticerya, Gigantococcus and Icerya. We provide a key to the genera based on adult females. We redescribe and illustrate the adult female and first‐instar nymph of the type species Crypticerya rosae (Riley & Howard), Echinicerya anomala Morrison, Gigantococcus maximus (Newstead) (adult female only), Gueriniella serratulae (Fabricius) and Icerya seychellarum (Westwood). We recognize Auloicerya Morrison as a junior synonym ( syn.n. ) of Icerya, and transfer the two Auloicerya species to Icerya as I. acaciae (Morrison & Morrison) comb.n. and I. australis Maskell comb.rev. We recognize Steatococcus and Proticerya Cockerell as junior synonyms ( syn.n. ) of Crypticerya. From Steatococcus, we transfer five species to Crypticerya [C. mexicana Cockerell & Parrott comb.rev. , C. morrilli (Cockerell) comb.n. , C. tabernicola (Ferris) comb.n. , C. townsendi Cockerell comb.rev. , C. tuberculata (Morrison) comb.n. ], four species to Gigantococcus [Gi. euphorbiae (Brain) comb.n. , Gi. gowdeyi (Newstead) comb.n. , Gi. madagascariensis (Mamet) comb.n. , Gi. theobromae (Newstead) comb.n. ] and three species to Icerya [I. assamensis (Rao) comb.n. , I nudata Maskell comb.rev. , I. samaraia (Morrison) comb.n. ]. From Icerya, we transfer 14 species to Crypticerya [C. brasiliensis (Hempel) comb.n. , C. colimensis (Cockerell) comb.n. , C. flava (Hempel) comb.n. , C. flocculosa (Hempel) comb.n. , C. genistae (Hempel) comb.n. , C. littoralis (Cockerell) comb.n. , C. luederwaldti (Hempel) comb.n. , C. minima (Morrison) comb.n. , C. montserratensis (Riley & Howard) comb.n. , C. palmeri (Riley & Howard) comb.n. , C. rileyi (Cockerell) comb.n. , C. similis (Morrison) comb.n. , C. subandina (Leonardi) comb.n. , C. zeteki (Cockerell) comb.n. ] and nine species to Gigantococcus [Gi. alboluteus (Cockerell) comb.n. , Gi. bimaculatus (De Lotto) comb.n. , Gi. brachystegiae (Hall) comb.n. , Gi. longisetosus (Newstead) comb.n. , Gi. nigroareolatus (Newstead) comb.n. , Gi. pattersoni (Newstead) comb.n. , Gi. schoutedeni (Vayssière) comb.n. , Gi. splendidus (Lindinger) comb.n. , Gi. sulfureus (Lindinger) comb.n. ]. From Crypticerya, we transfer seven species to Icerya [I. clauseni (Rao) comb.n. , I. jacobsoni Green comb.rev. , I. jaihind (Rao) comb.n. , I. kumari (Rao) comb.n. , I. mangiferae (Tang & Hao) comb.n. , I. natalensis (Douglas) comb.rev. , I. nuda Green comb.rev. ] and five species to Gigantococcus [Gi. bicolor (Newstead) comb.n. , Gi. cajani (Newstead) comb.n. , Gi. caudatus (Newstead) comb.n. , Gi. ewarti (Newstead) comb.n. , Gi. rodriguesi (Castel‐Branco) comb.n. ]. Both I. hyperici (Froggatt) and Palaeococcus dymocki (Froggatt) are syn.n. of I. nudata (all previously placed in Steatococcus). We recognize I. maynei Vayssière as a syn.n. of Gi. nigroareolatus, I. tremae Vayssière as a syn.n. of Gi. schoutedeni and I. townsendi plucheae Cockerell as a syn.n. of C. townsendi. We revalidate the species name I. crocea Green stat.reval. In addition, we transfer I. taunayi Hempel to Laurencella Foldi (Monophlebidae: Llaveiini) as L. taunayi (Hempel) comb.n. Four species, Coccus hirticornis Boyer de Fonscolombe, I. chilensis Hempel, I. insulans Hempel and I. paulista Hempel, are considered incertae sedis. We designate lectotypes for C. rosae, E. anomala and I. candida (a junior synonym of I. seychellarum). Following this revision, we recognize 74 species of Iceryini, distributed as follows: 22 in Crypticerya, one in Echinicerya, 19 in Gigantococcus, two in Gueriniella and 30 in Icerya.  相似文献

The genus Etiennea Matile‐Ferrero is synonymized with Hemilecanium Newstead (Hemiptera: Coccidae). We base this decision on a morphological comparative study of adult females, adult males and first‐instar nymphs (crawlers), including a phylogenetic analysis. We recovered a sister group relationship between the type species of the two genera, Etiennea villiersi Matile‐Ferrero and Hemilecanium theobromae Newstead; that is, each was more closely related to the other than either was to other species in their respective genera. All species hitherto included in Etiennea are transferred to Hemilecanium: H. bursera (Hodgson & Kondo) comb. nov., H. cacao (Hodgson) comb. nov., H. candelabra (Hodgson) comb. nov., H. capensis (Hodgson) comb. nov., H. carpenteri (Newstead) comb. nov., H. cephalomeatus (Hodgson) comb. nov., H. combreti (Hodgson) comb. nov., H. ferina (De Lotto) comb. nov., H. ferox (Newstead) comb. nov., H. gouligouli (Hodgson) comb. nov., H. halli (Hodgson) comb. nov., H. kellyi (Brain) comb. nov., H. madagascariensis (Hodgson) comb. nov., H. montrichardiae (Newstead) comb. nov., H. multituberculum (Hodgson) comb. nov., H. petasus (Hodgson) comb. nov., H. sinetuberculum (Hodgson) comb. nov., H. tafoensis (Hodgson) comb. nov., H. ulcusculum (Hodgson) comb. nov., and H. villiersi (Matile‐Ferrero) comb. nov. Keys to the adult females of all 26 species and known adult males and first‐instar nymphs are provided. The adult males and first‐instar nymphs of H. theobromae Newstead and E. villiersi Matile‐Ferrero are for the first time fully described and illustrated. One new potential pest species of Hemilecanium, H. uesatoi Kondo & Hardy sp. nov., which was collected on three islands of the Ryukyu Archipelago, Japan, is described and illustrated based on the adult female, adult male and first‐instar nymph. We discuss evidence that H. uesatoi is a new introduction to the Ryukyu Archipelago. The first‐instar nymphs of Hemilecanium can be divided into two distinct morphological groups, the petasus group and the theobromae group.  相似文献

The effectiveness of odour-baited targets treated with 0.8% deltamethrin in controlling Glossina austeni Newstead and G. brevipalpis Newstead (Diptera: Glossinidae) was evaluated in Zululand, South Africa. Targets were initially deployed in the three habitat types (grassland, woodland and forest) of two adjacent areas at a density of four targets per km(2). One area functioned as the treatment block (c. 35 km(2)) and included the focus of the target deployment, and the second area functioned as a barrier block (c. 40 km(2)) against tsetse fly re-invasion from the untreated area to the south. After 8 months, targets were removed from open grassland in both areas and target density in wooded habitats and sand forest was increased to eight per km(2). Twelve months later, all targets were removed from the barrier block and used to increase target density in the wooded and sand forest habitats of the treatment block to 12 per km(2). This target density was maintained for 14 months. In the treatment area, a 99% reduction in G. austeni females occurred after 13 months at a target density of eight per km(2) in wooded habitat; this was maintained for 22 months. Reduction in G. brevipalpis was less marked. The relatively poor reduction in G. brevipalpis is attributed to the high mobility of this species and its distribution throughout less wooded and more open habitats.  相似文献

Abstract. A phylogenetic analysis is carried out using Falagriini as the sister taxon of the tribe Sceptobiini. The trees resulting from a series of matrix manipulations and analyses are highly congruent. Two clades are produced: Dinardilla includes two species, and Sceptobius includes three species. Symbiochara Fenyes and Apteronina Wasmann are synonymized with Sceptobius Sharp, and Apteronina wasmanni Mann is synonymized with Sceptobius dispar Sharp.
All sceptobiine species are obligate inquilines of either Liometopum apiculatum Mayr or L.occidentale Wheeler (Hymenoptera: Formicidae: Dolichoderinae). Preliminary behavioural observations indicate that the subdivision into two clades is reflected in the types of interactions with host ants. Dinardilla beetles actively interact with the host, while Sceptobius beetles are more peripheral within the nest. These ecological and behavioural differences are believed to be produced by an interaction between ecological specialization, chance historical events, and geographic isolation during the speciation of the host ants.  相似文献

ABSTRACT. The phylogenetic relationships of two sphaerocerid genera, Alloborborus Duda (1923) and Crumomyia Macquart (1835), are analysed, and their taxonomic status within the tribe Copromyzini (= Copromyza Fallén s.lat.) is clarified. Accepted here are a monotypic Alloborborus , which includes A.pallifrons (FalléAn) from northern and central Europe, and twenty-six species of the Holarctic Crumomyia. Within Crumomyia , five species-groups are recognized: pedestris group: pedestris (Meigen); annulus group: immensa (Spuler), maculipennis (Spuler), annulus (Walker), nipponica (Richards), pruinosa (Richards); notabilis group: glabifrons (Meigen), glacialis (Meigen), absoloni (Bezzi), notabilis (Collin), rohaceki sp.n., zuskai (Roháček); nitida group: nitida (Meigen); setitibialis group: setitibialis (Spuler), pilosa sp.n., nigra (Meigen), parentela (Séguy), deemingi (Hackman), pollinodorsata (Papp), subaptera (Malloch), gelida (Hackman), fimetaria (Meigen), roserii (Rondani); unplaced species: hentscheli (Duda), hungarica (Duda), promethei (Nartshuk). Apterina Macquart, Fungobia Lioy and Speomyia Bezzi are synonymized with Crumomyia , and the following nominal species are synonymized: tuxeni Collin with nigra, freyi Hackman with setitibialis , and annulipes Duda with annulus. C. pruinosa is considered distinct from annulus, and Copromyza subaptera is placed in Crumomyia. The identity of C.glacialis , the type species of Crumomyia , is clarified, and lectotypes are designated for five nominal species: rufoannulata Duda, annulipes, annulus, flavipennis Haliday and pallifrons. The cladistic relationships of the species of Crumomyia and Alloborborus are established and their phylogeny and biogeography are discussed. Keys to the species of Crumomyia and to the Holarctic genera of the Copromyzinae are provided.  相似文献

Puparia of Glossina morsitans centralis (Machado), G.fuscipes fuscipes (Newstead) and G.brevipalpis (Newstead) were incubated at 25 +/- 1 degrees C, 28 +/- 1:25 +/- 1 degrees C, day:night or 29 +/- 1 degrees C throughout the puparial period, and maintained at 70-80% relative humidity. Puparial mortality was higher at 29 than at 25 degrees C (optimum temperature) in all three species, particularly in G.f.fuscipes and G.brevipalpis. Adults of G.m.centralis from puparia incubated at 29 degrees C, and those of this subspecies, G.f.fuscipes and G.brevipalpis from puparia incubated at 28:25 degrees C, day:night or 25 degrees C throughout, were infected as tenerals (27 h old) by feeding them at the same time on goats infected with Trypanosoma congolense (Broden) IL 1180 after the parasites were detected in the wet blood film. Infection rates on day 25 post-infected feed were higher in G.m.centralis from puparia incubated at 29 degrees C and in adults of the three different tsetse species from puparia incubated at 28:25 degrees C, day:night, than in those from puparia incubated at 25 degrees C. However, in G.f.fuscipes the labral and hypopharyngeal infection rates were not significantly different from those of the tsetse produced by puparia kept at 25 degrees C.  相似文献
