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 : 46-49

Docalidia jonesi , sp. nov.

(Plate IIID, Figs. 159–166 )

Length. Male 7.30 mm., female unknown.

External morphology. Moderately large, robust species. General color of dorsum dark brown to black; forewings with large, elongate light brown spot occupying middle of costa, veins with tiny yellow flecks; mesonotum and pronotum black; crown black with pale brown markings; eyes translucent (Plate IIID); face black, ocellocular area brown, clypeus with row of short, light brown stripes on each side of median line; clypellus with light brown longitudinal stripe on middle.

Head broad, narrower than pronotum, anterior margin broadly rounded; crown broad, slightly broader than eye, produced anteriorly about ¼ entire length, lateral margins convergent basally, foveate on each side of middle; eyes large, elongateovoid; pronotum slightly longer than crown; surface bullated; mesonotum large, nearly twice as long as pronotum; clypeus long, broad, lateral margins broadly convex, median longitudinal carina very prominent; clypellus about 1/3 as long as clypeus, narrow, median longitudinal ridge from base to apex.

Male genitalia. Pygofer in lateral view triangulate, caudodorsal process long, broad basally, attenuated distally, caudoventral process short, digitate ( Fig. 159 ); right subgenital plate long, narrow, glabrous ( Fig. 160 ); right style very long, longer than aedeagus, robust, in dorsal view with row of short spines on inner margin in approximately distal 1/3 ( Figs. 161, 162 ); aedeagus long, narrow, tubular, shaft in lateral view broadly convex, glabrous except for moderately long, ventral process below middle of shaft ( Figs. 163, 164 ); connective T-shaped, arms broad, membrane absent, median ridge extending distad of anterior margin of arms, stem short, broad ( Fig. 165 ); dorsal connective short, broad basally, tapered distally ( Fig. 166 ).

Material examined. Holotype male. COLOMBIA: Amazonas , PNN, Amacayacu Matamata, 3º41’S. 70º15’W., 150 m., Red 3/1/04-3/10/04, T. Pape & D. Arias, leg. M. 4326 (HB).

Etymology. The species is named for Joshua, R. Jones, Department of Entomology, Texas A & M University, College Station for his fine studies on the leafhopper subfamily Ledrinae .

Remarks. This species is similar to D. filamenta ( Nielson, 1992:300) in stylar configuration and can be distinguished by the presence of aedeagal ventral process, configuration of base of aedeagal shaft which is triangulate in ventral view and by the processes on the distal half of the style which are spinate rather than setate.
