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

Docalidia ventroelongata , sp. nov.

(Plate IVG), Figs. 260–267 )

Length. Male 8.00 mm., female unknown.

External morphology. Large, robust species. General color dorsum unicolorous light brown (forewings); mesonotum and pronotum black, with numerous yellow spots on pronotum; crown yellow with brown markings; eyes grey (Plate IVG); face brown with black markings on lateral borders of clypeus and clypellus.

Head broad, narrower than pronotum, anterior margin broadly rounded; crown about as wide as eye; produced anteriorly about ¼ entire length, disk foveate on each side of middle; pronotum slightly longer than crown; surface markedly rugulose on medial 1/3; mesonotum large, about twice as long as pronotum; forewings long, broad, venation typical; clypeus elongate, lateral margins broadly convex with distinctive median longitudinal carina; clypellus about 1/3 as long as clypeus, narrow, slightly inflated in basal half.

Male genitalia. Pygofer in lateral view triangulate, caudodorsal process short, caudoventral process broad, long, very narrow, sharply attenuated ( Fig. 260 ); segment X very long, narrow with exceptionally long, narrow ventral process ( Fig. 260 ); right subgenital plate short, narrow, outer lateral margin setaceous ( Fig. 261 ); right style long, longer than aedeagus, narrow, with supramedial stout spine, constricted distad of spine, apex pointed, short row of spines subapically in lateral view ( Figs. 262, 263 ); aedeagus tubular, broad medially in lateral view, toothed on lateral margin above gonopore, ventral process short, stubby, gonopore medial ( Figs. 264, 265 ); connective broadly Y-shaped, arms narrow, membrane absent, paired ridges extending beyond anterior arms, stem moderately long, broad ( Fig. 266 ); dorsal connective short, strapped shape, broad basally, tapered distally ( Fig. 267 ).

Material examined. Holotype male. COLOMBIA: Amazonas , PNN, Amacayacu Matamata, 3º41’X. 70º15’W., 150 m., Red. 3/1/04-3/10/04, T. Pape & D. Arias, leg., M.4326 (HB).

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

Remarks. This species is similar to D. scopa ( Nielson, 1979b:203) and can be distinguished by the much longer ventral process of segment X, by the short subapical row of spines on the style and the short, stubby, ventral aedeagal process.
