Systematics and phylogeny of the Neotropical treehopper subfamily Nicomiinae (Hemiptera, Membracidae) SistemĂĄtica e filogenia das cigarrinhas neotropicais da subfamĂlia Nicomiinae (Hemiptera, Membracidae)
Morphological characters of adults of the treehopper subfamily Nicomiinae Haupt, 1929 (Hemiptera, Membracidae) including seven genera (Eudonica gen. nov.; Euwalkeria Goding, 1926; Holdgatiella Evans, 1962; Nicomia StĂ„l, 1858; Nodonica Dietrich, McKamey& Deitz, 2001; Stalomia gen. nov.; and Tolania StĂ„l, 1858) and 22 species (16 new) are described and illustrated. Keys are provided for genera and for species of Euwalkeria, Holdgatiella, and Nicomia. Nomenclatural changes, based on study of the primary type material of 15 species, include three new combinations, one new synonymy, and reinstatement of one junior synonym. Eudonica has one species, Eudonica nanella sp. nov.; Euwalkeria has five species, including four new species: E. colorata sp. nov., E. distincta sp. nov., E. perdita sp. nov., E. rubrica sp. nov.; Holdgatiella has two species, one of which is described as new: Holdgatiella chiloensis sp. nov.; Nicomia has twelve species, nine of which are described as new: N. buccina sp. nov., N. harenosa sp. nov., N. inscripta sp. nov., N. jucunda sp. nov., N. monticola sp. nov., N. nigrifasciata sp. nov., N. notidana sp. nov., N. pulchella sp. nov., N. serrata sp. nov.; Nodonica has one species, Nodonica bispinigera Dietrich, McKamey & Deitz; and Stalomia has one species, Stalomia veruta sp. nov. Tolania contains eleven previously described species and nearly 60 new species, which will be treated in a later publication. Three new combinations are proposed: one species described in Nicomia is placed in the tribe Abelini (Centrotinae) as Abelus retrospinosus (Lethierry) comb. nov.; one species previously placed in Nicomia is transferred to the genus Tolania as T. obliqua (Walker, 1858), comb. nov.; one species described in Holdgatiella is placed in the genus Tolania as T. stria (Cryan & Deitz, 2002), comb. nov. One new synonymy is proposed: Hoplophera [sic] cicadoides Walker, 1862, syn. nov., a junior synonym of Nicomia interrupta StĂ„l, 1858. Nicomia subfasciata StĂ„l, 1858, is reinstated. The results of a phylogenetic analysis based on morphology are presented, illustrating the hypothesized relationships among species and genera of Nicomiinae. The analysis supports the broader concept of Nicomiinae proposed here. The monophyly of this group is supported by eleven characters, and all of the included genera are also monophyletic.<br>Caracteres morfolĂłgicos dos adultos das cigarrinhas da subfamĂlia Nicomiinae Haupt, 1929 incluindo sete gĂȘneros (Eudonica gen. nov.; Euwalkeria Goding, 1926; Holdgatiella Evans, 1962; Nicomia StĂ„l, 1858; Nodonica Dietrich, McKamey& Deitz, 2001; Stalomia gen. nov. e Tolania StĂ„l, 1858), e 22 espĂ©cies (16 espĂ©cies novas) sĂŁo descritos e ilustrados. Chaves taxĂŽnomicas para identificação de gĂȘneros e espĂ©cies de Euwalkeria, Holdgatiella e Nicomia sĂŁo fornecidas. Mudanças nomenclaturais, baseadas no estudo de material-tipo primĂĄrio de 15 espĂ©cies, incluem trĂȘs combinaçÔes novas, uma nova sinonĂmia e revalidação de um sinĂŽnimo-jĂșnior. Eudonica inclui uma espĂ©cie nova, Eudonica nanella sp. nov.; Euwalkeria inclui cinco espĂ©cies, sendo quatro novas: E. colorata sp. nov., E. distincta sp. nov., E. perdita sp. nov. e E. rubrica sp. nov.; Holdgatiella inclui duas espĂ©cies, sendo uma nova: Holdgatiella chiloensis sp. nov.; Nicomia inclui 12 espĂ©cies, sendo nove novas: N. buccina sp. nov., N. harenosa sp. nov., N. inscripta sp. nov., N. jucunda sp. nov., N. monticola sp. nov., N. nigrifasciata sp. nov., N. notidana sp. nov., N. pulchella sp. nov. e N. serrata sp. nov.; Nodonica inclui uma espĂ©cie, Nodonica bispinigera Dietrich, McKamey & Deitz e Stalomia inclui uma espĂ©cie nova, Stalomia veruta sp. nov. Tolania inclui 11 espĂ©cies previamente descritas e aproximadamente 60 espĂ©cies novas, as quais serĂŁo tratadas posteriormente em outra publicação. TrĂȘs combinaçÔes novas sĂŁo propostas: Abelus retrospinosus (Lethierry) comb. nov., previamente em Nicomia, Ă© transferida para a tribo Abelini (Centrotinae); Tolania obliqua (Walker, 1858) comb. nov., previamente em Nicomia; e Tolania stria (Cryan & Deitz, 2002) comb. nov., previamente em Holdgatiella. Uma nova sinonĂmia Ă© proposta: Hoplophera [sic] cicadoides Walker, 1862 Ă© considerada um sinĂŽnimo junior de Nicomia interrupta StĂ„l, 1858. A espĂ©cie Nicomia subfasciata StĂ„l, 1858 Ă© revalidada. Os resultados de uma anĂĄlise filogenĂ©tica baseada em caracteres morfolĂłgicos sĂŁo apresentados, ilustrando as possĂveis relaçÔes entre gĂȘneros e espĂ©cies de Nicomiinae. A anĂĄlise suporta o conceito proposto mais amplo de Nicomiinae. O monofiletismo da subfamĂlia Ă© suportado por 11 caracteres e todos os gĂȘneros incluĂdos sĂŁo tambĂ©m recuperados como monofilĂ©ticos
Crossâreactive antigenic determinants present on different Plasmodium falciparum bloodâstage antigens
The cytoplasmic/transmembrane domain of dipeptidyl IV, a type II glycoprotein, contains an apical targeting signal that does not specifically interact with lipid rafts
The expression of the Mr 30 000 antigen in the third stage larvae of Brugia pahangi
Summary The expression of the Mr 30 000 surface antigen in the third stage larvae (L,3) of Brugia pahangi has been investigated. The antigen could be detected only with great difficulty in the mosquito derived Li externally labelled with 125I but was more easily labelled in 24 and 48 h post-infective larvae harvested from the vertebrate host. Labelling of a detergent extract of mosquito derived L3 with 125I demonstrated that the Mr 30 000 antigen was indeed present in this life cycle stage, presumably in an internal localization. It seems likely that the Mr 30 000 antigen is not fully expressed in the parasite cuticle until after infection of the vertebrate host. The data presented also suggest that there arc major differences in the surface properties of the mosquito derived Li compared to the p.i. L3 harvested from the vertebrate host
