Euragallia adelinae sp. nov.
( Figures 4A–G View Figure 4 )
Description
Length
Male holotype, 5.8 mm.
Head and thorax
General ground colour pale brown. Crown ( Figure 4A View Figure 4 ) shorter medially, widened next to inner margin of eyes; with pair of slender foveae equally distant between median line and eyes, each one with adjacent dark brown maculae; with brown stripe on median portion extending to face. Face ( Figure 4B View Figure 4 ) with inverted dark brown Y-shaped mark; outer area adjacent to ocelli with pair of dark brown maculae extending to eyes. Frons ( Figure 4B View Figure 4 ) with several irregular dark brown maculae forming pair of lateral rows; lateral portions dark brown. Clypeus with dark brown macula on lateral and lower portion fused with irregular ones from frons, remaining area brown; genae slightly striated. Pronotum ( Figure 4A View Figure 4 ) anterior portion with pair of dark brown maculae located on narrow depressions, lateral portions with pair of subtriangular dark brown marks and median area with elliptical dark brown stripe not attaining any margin. Mesoscutum with pair of laterobasal triangular maculae and pair of rounded marks at central portion, dark brown; mesoscutellum with pair of brown maculae at laterobasal portions, pair of pale brown dots at central portion.
Genitalia
Pygofer ( Figure 4C View Figure 4 ), in lateral view, with posterodorsal margin produced into narrow blunt lobe. Subgenital plates ( Figure 4D View Figure 4 ), in ventral view, totally fused to each other, except for apical area; proximal half with less sclerotized area followed by several irregular depressions (located more internally) and striated surface on median portion; distal half narrowing gradually toward apex, bearing scattered setae; subapical area with scaly surface. Styles ( Figure 4E View Figure 4 ), in dorsal view, well developed with basal region directed outward, broadening up to apical region; apical area bearing scattered setae; distal margin almost entirely truncate and with tooth-like projection; shaft with short lateral process for attachment of plates on inner margin and well-developed dorsal projection for articulation with connective. Connective, in lateral view, slender, membranous, fused to aedeagus. Aedeagus ( Figure 4F View Figure 4 ), in lateral view, symmetrical; simple, with atrial region bearing dorsal round lobe; shaft directed ventrally, then distinctly curved posterodorsally, forming approximately a right angle to basal portion; apical area curved ventrally; apex bifurcate with subacute projections ( Figure 4G View Figure 4 ). Anal tube, in lateral view, with segment X well developed and roundish.
Etymology
The new species is described in honour of Dr. Adeline Soulier-Perkins (Departement de Systematique et Evolution, Museum National d’Histoire Naturelle, Paris, France), who has kindly taken pictures that were extremely useful for the discovery of this new species.
Type material
Holotype, male: Brazil, Pará State. “Brasil Pará \ São Felix do Xingu \ Garimpo da\ liberdade\ 15 a 19. XI. 1951 ”; “ Brasil Pará \ B. Mascarenhas ”; “Homóptera\ Auchenorrhyncha\ Cicadeloidea [sic]: Cicadellidae \ Incorporação: 30. IV. 1999 ” ( MPEG).
Remarks
Euragallia major has some features similar to those of E. adelinae , such as the general colour, pygofer and aedeagal aspects. Despite their similarities, the new species can be separated from E. major , and from the others of the genus, by the following characters: (1) pygofer ( Figure 4C View Figure 4 ) with posterodorsal margin produced into narrow blunt lobe; (2) subgenital plates ( Figure 4D View Figure 4 ), on proximal half, with area less sclerotized followed by several irregular depressions and striated surface on median portion; subapical area with scaly surface; (3) aedeagal apex ( Figure 4G View Figure 4 ) bifurcate with subacute projections.
