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 : 19-22

Docalidia barbata , sp. nov.

(Plate 1D, Figures 25–32 )

Length. Male 6.30 mm., female unknown.

External morphology. Moderately large, robust species. General color of dorsum black and orange; forewings black with broad transverse, orange band medially, narrow transverse, orange band apically; mesonotum and pronotum dark brown to black; crown orange; eyes reddish brown (Plate 1D); face dull orange, clypeal carina black.

Head broad, narrower than pronotum, anterior margin broadly rounded; crown broad, about as wide as eye, produced anteriorly about ¼ entire length, lateral margins convergent basally, disk foveate on each side of middle; pronotum slightly longer than crown, surface bullated anteriorly with 3 large, elongate, smooth patches posteriorly; mesonotum about half again as long as pronotum; forewings long, broad, venation typical of the genus; clypeus long, broad, lateral margins broadly convex, median longitudinal carina prominent; clypellus short, less than 1/3 as long as clypeus, broad, slightly inflated baso-medially.

Male genitalia. Pygofer in lateral view elongate, caudodorsal processs moderately long, stout, caudoventral process reduced to small, elongate, membranous lobe below base of caudodorsal process ( Fig. 25 ); right subgenital plate long, broadly expanded along middle ¾ of outer margin ( Fig. 26 ); right style long, about as long as aedeagus, distal ¼ expanded in dorsal and lateral views, spinate subbasally with outer margins densely setose in dorsal and lateral views ( Fig. 27, 28 ); aedeagus long, shaft narrowly tubular, with moderately long, subapical spine on ventral margin, gonopore cryptic ( Figs. 29, 30 ); connective T-shaped, arms narrow, median ridge extending beyond anterior margin of arms, stem short, narrow ( Fig. 31 ); dorsal connective short, narrow, base broad, tapered distally ( Fig. 32 ).

Material examined. Holotype male. COLOMBIA: Amazonas , PNN, Amacayacu, San Martin, 3º23’S. 70º6’W., 150 m., 3 Dec 01–17 Dec 01, M.2773, Malaise, D. Chota (HB).

Etymology. The name is descriptive for the sharp, straight aedeagal spine.

Remarks. From D. pusilla ( Nielson, 1979:252) to which it is nearest, D. barbata can be separated by the narrower, tubular shaft of the aedeagus and presence of subbasal spines on the style which are entirely absent in D. pusilla .
