Nielson, M. W., 2011, New species in the Neotropical genus Docalidia with a key to known species, notes on distribution, taxonomy and a synoptic catalogue of the genus (Hemiptera: Cicadellidae: Coelidiinae: Teruliini) 2952, Zootaxa 2952 (1), pp. 1-86 : 67-70

Docalidia ventrospinata , sp. nov.

(Plate IVH), Figs. 268–276 )

Length. Male 7.00 mm., female unknown.

External morphogy. Moderately large, robust species. General color of dorsum dark brown to black with broad transverse, yellow band near middle of forewings, apex yellow, veins with small, yellow spots; eyes dark brown; crown yellow marked with light brown markings on each side of middle (Plate IVH); face reddish brown with 4 yellow spots on clypeus.

Head distinctly narrower than pronotum, anterior margins broadly rounded; crown narrower than eye, disk slightly elevated; eyes large, elongate ovoid; pronotum moderately large, slightly longer than crown, inflated medially; mesonotum large, about twice as long as pronotum; forewings long, broad, venation typical; clypeus long, broad, lateral margins broadly convex, median longitudinal carina prominent; clypellus about 1/3 as long as clypeus, lateral margins expanded distally, median longitudinal ridge slightly inflated in basal half.

Male genitalia. Pygofer in lateral view elongate-triangular, caudodorsal process tenuated distally, caudoventral processs absent ( Fig. 268 ); segment X in ventral view toothed on lateral margins ( Fig. 269 ); left subgenital plate long, outer lateral margin broadly convex along middle 2/3 ( Fig. 270 ); right style long, about as long as aedeagus, in dorsal view, robust, distal 1/3 of apophysis broad, with row of long spines on inner lateral margin ( Fig. 271 ), in lateral view apophysis narrow ( Fig. 272 ); aedeagus tubular, very narrow throughout, ventral process long, subapical ( Figs. 273–274 ); connective broadly T-shaped, arms curved anteriorly in distal half, membrane absent, medial ridge present from base to anterior margin of arms, base broad ( Fig. 275 ); dorsal connective, short, strapped shaped in dorsal view ( Fig. 276 ).

Material examined. Holotype male. BOLIVIA: Santa Cruz, 5 km. SSE Buena Vista , Hotel Flora & Fauna, 440 m., W63º39.128, S17º 29.925’, 10-22-2004, J. E. Eger, Coll. at UV, MV and incandescent light ( NMNH).

Etymology. The name is descriptive for the ventral process of segment X.

Remarks. From D. gracilitas ( Nielson, 1979b:260) to which it has similar aedeagal features, ventrospinata , sp. nov. can be distinguished by the toothed ventral margin of segment X, the long caudorsal margin of the pygofer and the absence of a lobe below the base of the caudodorsal pygofer process.
