Docalidia mejdalanii View in CoL , sp. nov.

(Plate IIIH, Figs 192–200 View FIGURES 192–200 )

Length. Male 7.60 mm., female unknown.

External morphology. Moderately large, robust species. General color of dorsum orange and black; forewings orange with broad, black, transverse chevron-shaped band medially, base and clavus suffused with black; mesonotum black; pronotum orange basally, black distally; crown yellow; eyes translucent (Plate IIIH); face orange, suffused with black patches bordering clypeus, clypellus below eyes.

Head broad, narrower than pronotum, anterior margin broadly rounded; crown broad, about as wide as eye, produced anteriorly about ¼ of entire length, disk foveate on each side of middle; eyes large, elongate ovoid; pronotum slightly shorter than crown, surface bullated; mesonotum large, nearly twice as long as pronotum; forewing long, very broad, venation typical; clypeus long, broad, lateral margins broadly convex, with distinct median longitudinal carina; clypellus about 1/3 as long as clypeus, narrow median longitudinal ridge inflated in basal 2/3, lateral margins expanded apically.

Male genitalia. Pygofer in lateral view narrowly triangulate, caudodorsal process long, broad basally, sharply attenuated distally, caudoventral process long, narrow, sharply attenuate distally ( Fig. 192 View FIGURES 192–200 ); segment X long, with equally long ventral process ( Fig. 193 View FIGURES 192–200 ); right subgenital plate moderately long, broad, with unique, single apical process on inner lateral margin, glabrous ( Fig. 194 View FIGURES 192–200 ); right style moderately long, longer than aedeagus, robust, with prominent medial process directed distally, nearly reaching apex of apophysis, apex of apophysis bifurcate, long slender accessory process basad of bifurcation, extending more than half of its length beyond apex, with secondary medial spine ( Figs. 195, 196 View FIGURES 192–200 ); aedeagus moderately long, tubular, with distinctive, subapical ventral process, process with row of teeth on each side, gonopore supramedial, exiting ventrally ( Figs. 197, 198 View FIGURES 192–200 ); connective, nearly Tshaped, arms broad, membrane absent, medial ridge extending beyond anterior margin of arms, stem moderately long, narrow ( Fig. 199 View FIGURES 192–200 ); dorsal connective long, strapped-shaped in dorsal view ( Fig. 200 View FIGURES 192–200 )

Material examined. Holotype male. COLOMBIA: Amazonas , PNN, Amacayucu Cabaña Lorena, 3º0’S. 69º59’W., 210 m., 27 Aug 01–1 Sep 01, M. 2237, Malaise, D. Campos (HB). GoogleMaps

Etymology. The species is named for Gabriel Mejdalani, Professor of Entomology, Departamento de Entomologia, Museu Nacional, Universidade do Federal Rio de Janeiro, Brazil for his outstanding taxonomic research on the subfamily Cicadellinae and his influential leadership in promoting taxonomic research among students, several of whom who have earned their Ph. D. degrees and produced fine taxonomic works.

Remarks. From D. foveata ( Nielson, 1979b:198) to which it is similar in style and aedeagal features, mejdalanii , sp. nov. can be separated by the orange and black coloration, the configuration of the caudodorsal and caudoventral processes of the pygofer and by the single, long apical process on the subgenital plate.
