( Figures 1A–E View Figure 1 , 2A–C View Figure 2 )
Holotype description
Length
Male holotype, 4.4 mm (male paratype, 4.4 mm; female paratype, 4.5 mm).
Head and thorax
General ground colour pale brown. Eyes bulbous. Crown shorter medially, widened next to inner margin of eyes; bearing pair of slender foveae equally distant between median line and compound eyes, each fovea surrounded by dark brown macula; with slight concave depression and brown stripe on median portion. Face with brown, incomplete inverted Y-shaped macula between ocelli; tiny brown maculae adjacent to ocelli; pair of dark brown maculae close to inner margins of eyes. Frons with several irregular brown maculae forming pair of lateral rows; clypeus brown on lower portion. Pronotum finely striated with pair of slender depressions close to anterior margin; median area with brown stripe reaching only posterior margin; bearing some brown asymmetrical stripes, mostly longitudinal, disposed randomly. Mesoscutum with pair of lateral, triangular brown maculae; with pair of tiny foveae behind scutoscutellar suture. Forewings ( Figure 1A View Figure 1 ) rugulose, pale brown, with veins pronounced; distal half with venation reticulated.
Male genitalia
Pygofer ( Figure 1B View Figure 1 ), in lateral view, bearing on anterior margin apodeme with round apex; posterior margin with two-thirds of superior portion forming pair of welldeveloped projections with subacute apex directed ventrally, remaining one-third projected posteriorly, slightly striated, narrowing toward truncate apex. Subgenital plates ( Figure 1C View Figure 1 ), in ventral view, elongate, totally fused, narrowing toward distal portion with broader apex; bearing long scattered setae; in lateral view, extending posteriorly beyond pygofer apex. Styles ( Figure 1D View Figure 1 ), in dorsal view, with proximal third directed inward and distal third directed abruptly inward with small apical tooth and few long setae on inner margin; fork absent. Connective, in lateral view, slender, membranous, fused to aedeagus. Aedeagus ( Figure 1E View Figure 1 ) simple, symmetrical; atrial region well developed with small dorsal projection directed caudally and pair of lobes directed dorsally; shaft strongly curved dorsally with pair of small dorsal toothlike processes apically, directed anteriorly. Anal tube, in lateral view, with segment X small.
Female paratype
Colour
Colour features mostly similar to those of the holotype.
Female genitalia (based on one specimen)
Sternite VII ( Figure 2A View Figure 2 ), in ventral view, reduced; posterior margin round with deep median invagination; base of ovipositor exposed. First valvulae, in lateral view, dorsally curved from base; ventral interlocking device distinct, located on basiventral portion of shaft; dorsolateral surface with reticulate sculptured area formed by oblique rows of scalelike processes; ventroapical region with scale-like processes; dorsoapical and ventroapical margins pseudodentate; apex subacute. First valvifer exposed and strongly developed. Second valvulae ( Figure 2B View Figure 2 ), in lateral view, slightly curved dorsally from base, with broadest point on apical fourth; dorsal hyaline area absent; dorsal prominence very pronounced on apical fourth; teeth ( Figure 2C View Figure 2 ) mostly subtriangular, not bearing denticles, positioned on distal half of dorsal margin, mostly uniform in size and shape toward apex; shaft apex subacute. Gonoplacs, in lateral view, with proximal half broadening gradually toward median portion; apex narrowly rounded; surface with tiny spiniform processes and setae on apical portion and extending anteriorly along ventral margin.
Intraspecific variation (based on all male and female specimens)
The specimens may be generally darker and present small variations on the reticulation pattern on the forewing venation.
Etymology
The new species is named in honour of Prof. Dr. Gabriel Luís Figueira Mejdalani (Museu Nacional, Universidade Federal do Rio de Janeiro), who has published fine contributions on Neotropical leafhoppers.
Type material
Brazil, Sergipe State. Holotype: male, “ Canindé do São / Francisco, SE/ 15. IV. 2000 / L. Iannuzi leg ( DZUP). One male and one female paratypes with the same data as holotype, excepting “ 8. IV. 2000 ” ( DZUP, MNRJ).
Remarks
Among the species included in the major complex, E. furculata , E. machaera and E. prion are the ones that have the aedeagus most similar to that of E. mejdalanii . The new species can be separated from the others within the complex, as well as from the others in the genus, by the following characters: (1) pygofer ( Figure 1B View Figure 1 ) bearing pair of unique projections with acute apex; (2) aedeagal shaft ( Figure 1E View Figure 1 ) strongly curved dorsally with small, dorsoapical tooth-like process directed anteriorly.
