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 : 28

Docalidia cornicula , sp. nov.

(Plate IIA, Figs. 66–73 )

Length. Male 7.70 mm., female unknown.

External morphology. Moderately large, robust species. General color or dorsum uniformly light brown; mesonotum and pronotum with black spots; crown light brown; eyes translucent (Plate IIA); face black with few light brown spots on clypus and ocellocular area, median brown stripe on clypellus.

Head broad, narrower than pronotum, anterior margin broadly rounded; crown broad, slightly narrower than eye, produced distally about ¼ of entire length, lateral margins parallel, disk foveate of each side of middle; eyes large, semiglobular; pronotum slight longer than crown, surface bullated; mesonotum large, nearly twice and long as pronotum; forewings long, broad, venation typical; clypeus long, broad, lateral margins broadly convex, with prominent median longitudinal carina; clypellus about 1/3 as long as clypeus, narrow, with inflated longitudinal ridge from base to near apex.

Male genitalia. Male pygofer in lateral view rectangulate, caudodorsal process long, attenuated distally, caudoventral process reduced to small elongate lobe below base of caudodorsal process ( Fig. 66 ); right subgenital plate long, very broad, glabrous, outer lateral margin membranous in about basal 3/4 ( Fig. 67 ); right style in dorsal and lateral views very long, longer than aedeagus, very robust ( Figs. 68, 69 ), in dorsal view with subapical flange, margin setaceous, few setae below, small spine and flange apically ( Fig. 68 ); aedeagus with shaft in lateral and ventral views broad in basal half, moderately long setae medially, gonopore medial, exiting laterally ( Figs. 70, 71 ); connective T-shaped, arms curved distally, paired ridge extended distally beyond anterior margin of arms, base broad, horn shaped ( Fig. 72 ); dorsal connective in dorsal view plate-like, broad basally ( Fig. 73 ).

Material examined. Holotype male. COLOMBIA: Vaupés, R. N. Mosiro-Itajura (Capari), Central Ambiental , 1º4’S 69º 31E /. 60 m., 3/27/2003 – 4/9/2003, M.3620, Malaise, J. Pinzon (HB).

Etymology. The name is descriptive for the short, horn shaped base of the connective.

Remarks. This species is nearest to D. cornipes , sp. nov. The style in dorsal view has a much smaller apical spine and flange, the subgenital plate is narrower, the pygofer caudodorsal process sharper, and the aedeagus shorter than the style and in ventral view has the preatrium very narrow.
