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 : 14-17

Docalidia accurationis , sp. nov.

(Plate 1A, Figures 1–9 )

Length. Male 7.20 mm., female unknown.

External morphology. Moderately large, robust species. General color of dorsum dark brown to black throughout except for flavous crown (Plate 1A); face entirely black.

Head much narrower than pronotum, anterior margin broadly rounded; crown broad, wider than eye; lateral margins nearly parallel, depressed on each side of middle; eyes large, semiglobular; pronotum large, median length about 1/3 longer than crown, surface bullated; mesonotum large, median length about 1/3 longer than pronotum; forewings long, broad, venation typical of genus; clypeus long, narrow, lateral margins convex, with distinct median longitudinal carina; clypellus about 1/3 as long as clypeus, lateral margins nearly parallel.

Male genitalia. Pygofer in lateral view quadrate excluding caudal processes, caudoventral process short, very broad in basal 5/6, apex narrow, hooked shaped, caudodorsal process extremely long, about as long as body of pygofer, narrow in basal 4/5, triangulate in distally ( Fig. 1 ); segment X long, with distinctive ventral process ( Fig. 2 ); right subgenital plate large, very broad subapically, glabrous ( Fig. 3 ); right style long, nearly as long as aedeagus with triangulate, toothed supramedial flange, small lenticular flange subapically ( Figs. 4, 5 ); aedeagus asymmetrical, tubular, in lateral view shaft broadly sinuate with distinctive subapical spine projecting basally, gonopore medial on ventral margin ( Fig. 6 ), in ventral view shaft very narrow in distal 5/6 ( Fig. 7 ); connective distinctive, nearly T-shaped, arms narrow, stem short, membrane absent ( Fig. 8 ); dorsal connective in dorsal view moderately long, strapped shape ( Fig. 9 ).

Material examined. Holotype male. BRAZIL: Honaonia (sic) [Rondonia], 62 km., SE Ariquemes, 22–31 Oct. 1997, W. J. Hansen ( NMNH).

Etymology. The name is descriptive for the similar configuration of the apex of segment X ventral process and caudodorsal pygofer process.

Remarks. This species is nearest to D. iacula ( Nielson, 1979 e: 215) known only from Peru, in configuration of the pygofer and stylar processes. The long ventral process of segment X and triangulate apex of the caudodorsal pygofer process will readily distinguish accurationis from iacula .
