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 : 73

Docalidia zhangi , sp. nov.

(Plate VB, Figs. 285–293 )

Length. Male 7.20 mm., female unknown.

External morphology. Moderately large, robust species. General color of dorsum black and pale orange; forewings black with broad, translucent band below mesonotum, large pale orange spot on clavus, veins black with small pale orange spots; mesonotum and pronotum black, small, pale orange spots on pronotum; crown orange with pale yellow markings; eyes translucent (Plate VB); face with clypeus and ocellocular area orange, black stripe below eyes.

Head broad, distinctly narrower than pronotum, anterior margin broadly rounded; crown broad, slightly wider than eye, produced anteriorly about ¼ of entire length; foveate on each side of middle; eyes large, semiglobular; pronotum slightly longer than crown, surface bullated; mesonotum large, about half again as long as pronotum; forewings long, broad, venation typical; clypeus elongate, broad, lateral margins broadly convex, median longitudinal carina distinct; clypellus about 1/3 as long as clypeus, narrow, median longitudinal ridge inflated in basal 2/3.

Male genitalia. Pygofer in lateral view small, subrectangulate, caudodorsal process very long, about equal in length of pyogfer body, slightly sinuate, apex trumpet shaped, caudoventral process very small, hooked apically ( Fig. 285 ); segment X long, broad apically, ventral process large with small curved process on ventral margin ( Fig. 286 ); right subgenital plate, long, broad throughout, glabrous ( Fig. 287 ); right style long, longer than aedeagus, apophysis slender with large, triangulate, subapical flange ( Figs. 288, 289 ); aedeagus with shaft broad in basal 1/3, sinuate in lateral view with small subapical ventral process, gonopore basad of spine, large, exiting ventrally ( Figs. 290, 291 ); connective broadly T-shaped, arms narrow, curved anteriorly at apex, membrane and medial ridge absent, stem short ( Fig. 292 ); dorsal connective short, strapped shaped, arising laterally in ventral view ( Fig. 293 ).

Material examined. Holotype male. COLOMBIA: Putumayo, PNN, La Paya, Cabaña La Paya , 0º2’S. 75º12’W., 330 m., 5 Dec 01–25 Dec 01, M. 2797, Malaise, E. Lozano (HB).

Etymology. The species is named Dr. Yalin Zhang, Institute of Entomology, Northwestern Agricultural University, Yangling, China for his productive research on the leafhoppers of China, particularly on the subfamilies Coelidiinae and Stegelytrinae .

Remarks. This species is similar to D. ruficosta (Jacobi) ( Nielson, 1979b:213) in style and aedeagal features and can be distinguished by the very large, subapical, triangulate flange on the style, the extremely long, caudodorsal pygofer process with its trumpet shaped apex and the very short, hooked shaped caudoventral pygofer process.
