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 : 25

Docalidia caudata , sp. nov.

(Plate 1G, Figures 49–56 )

Length. Male 6.80 mm., female unknown.

External morphology. Moderately large, robust species. General color of dorsum black and orange similar to barbata , forewings with broad, transverse black band medially; mesonotum black; pronotum orange, large triangular black marking on middle of posterior margin; crown dull orange, eyes translucent (Plate 1G); face orange, clypeus with short black marking in distal half.

Head broad, narrower than pronotum, anterior margin broadly rounded; crown broad, slightly wider than eye, produced anteriorly about ¼ entire length, slightly foveate on each side of middle; eyes large, semiglobular; pronotum slightly longer than crown, surface sparsely bullated, bullae with short setae; mesonotum large, about half again and long as pronotum; forewings long, broad, venation as in genus; clypeus long, broad, lateral margins broadly convex, median longitudinal carina prominent; clypellus short, about 1/3 as long as clypeus, narrow, slightly inflated basomedially, lateral margins expanded distally.

Male genitalia. Pygofer in lateral view with 2 equally configurated dorsal processes, processes moderately long, stout ( Fig. 49 ); segment X very large, longer than pygofer with very long ventral process, ventral process twice as long as segment X, attenuated in distal half ( Fig. 49 ); right subgenital plate very long, narrow, surface sparsely setose, with distinctive, single apical seta on inner lateral margin ( Fig. 50 ); right style very long, longer than aedeagus, with long spine on middle of apophsis, row of teeth on distal 1/3 of inner lateral margin in dorsal view ( Figs. 51, 52 ); aedeagus long, shorter than style, tubular with toothed, subapical ventral spine ( Figs. 53, 54 ); connective broadly Y-shaped, arms chitinized on ventral margin, membranous anteriorly, stem short ( Fig. 55 ); dorsal connective moderately long, strapped shape ( Fig. 56 ).

Material examined. Holotype male. COLOMBIA: Amazonas , PNN, Amacayacu, Matamata, 3º23’S 70º 6’W., 150 m., 2 Oct 01–15 Oct 01, M. 2248, Malaise D. Chota (HB).

Etymology. The name is descriptive for the distinctive, very long seta on the apex of the subgenital plate.

Remarks. This species, nearest to D. dorsti ( Nielson, 1982g:249) in configuration of segment X ventral process and style, can be distinguished by the longer ventral process of segment X, the unique, very long, apical seta on the subgenital plate and by the uniform row of spines on the apical third of the style.
