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 : 32

Docalidia curvatura , sp. nov.

(Plate IIC, Figs. 83–90 )

Length. Male 7.30 mm., female unknown.

External morphology. Moderately large, robust species. General color of dorsum yellow and black; forewing concolorous yellow; mesonotum black; pronotum yellow, with suffused black markings; crown yellow with black markings; eyes translucent (Plate IIC); face black except anterior margin, ocellocular area and clypellus ridge, yellow.

Head broad, narrower than pronotum, anterior margin broadly rounded; crown broad, about as wide as eye, produced distally about ¼ entire length, foveate on each side of middle; eyes large, elongateovoid; pronotum about as long as crown, surface bullated; mesonotum large, nearly 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, narrow, median longitudinal ridge inflated in basal 2/3, lateral margins expanded distally.

Male genitalia. Pygofer in lateral view rectangulate, caudodorsal process long, robust, tapered distally, caudoventral process very long, narrow, broadly curved ventrally ( Fig. 83 ); segment X long with medial, semipherical ventral lobe ( Fig. 83 ); right subgenital plate long, inner lateral margin straight, outer later margin rounded, tapered distally, setose ( Fig. 84 ); right style very long, narrow, sinuate, glabrous, about as long as aedeagus ( Figs. 85, 86 ); aedeagus more or less tubular, broadly sinuate, with short spine subapically, triangulate flange below spine in dorsal view, gonopore medial ( Figs. 87, 88 ); connective nearly T-shaped, arms narrow, not membranous, stem short ( Fig 89 ); dorsal connective, short, base broad ( Fig. 90 ).

Material examined. Holotype male. COLOMBIA: Amazonas , PNN, Amacayacu, Matamata, 3º41’S. 70º25’W., 150 m., 8/14/2000 – 8/14/2000, M. 3547, Red A. Parente (HB).

Etymology. The name is descriptive for the long, broadly curved, caudoventral process of the pygofer.

Remarks. This species is nearest to D. limpidosparsa (Stål) ( Nielson, 1979b:190) and can be distinguished by the longer, broadly curved, caudoventral process of the pygofer, longer style, shorter aedeagal ventral spine and presence of a triangulate flanged below ventral spine on the aedeagus.
