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 : 44

Docalidia gigantea , sp. nov.

(Plate IIIB, Figs. 143–150 )

Length. Male 8.20–8.80 mm., female unknown.

External Morphology. Large, robust species. General color of dorsum yellow and black; forewings concolorous brown throughout; mesonotum black; pronotum black with small yellow spots; crown yellow; eyes translucent (Plate IIIB); face predominately yellow; clypeus with row of short black transverse bands on each side, suffused with longitudinal black stripe medially, 3 small spots in center of lora, black spot under each eye.

Head broad, distinctly narrower than pronotum, anterior margin broadly rounded; crown broad, wider than eye, produced anteriorly about ¼ of entire length, foveate on each side of middle; eyes large, elongate ovoid, pronotum slightly longer than crown, surface bullated; mesonotum large, about twice as long as pronotum; clypeus long, broad, lateral margin broadly convex, median longitudinal carina prominent; clypellus about 1/3 as long as clypeus, narrow, median longitudinal ridge inflated in basal 2/3, lateral margins flared apically.

Male genitalia. Pygofer in lateral view large, triangulate, caudodorsal process moderately long, robust, caudoventral process short, broad basally, apex ligulate, closely appressed to base of caudodorsal process ( Fig 143 ); right subgenital plate long, very narrow throughout length, twisted medially, setaceous along middle of outer lateral margin ( Fig. 144 ); right style extremely long, nearly twice as long as aedeagus, very narrow, broadly curved in lateral view, row of short setae in distal 2/3 on inner lateral margin in dorsal view ( Figs. 145, 146 ); aedeagus long, narrow, shaft broad in basal half, narrowed in distal half in lateral view, flanged near middle and subapically, in ventral view shaft with dorsal apodeme flared laterally, gonopore submedial, exiting ventrally ( Figs. 147, 148 ); connective T-shaped, arms broad, membrane absent, stem long, broad ( Fig. 149 ); dorsal connective short, strapped shape, broadly basally, tapered distally in dorsal view ( Fig. 150 ).

Material examined. Holotype male. COLOMBIA: Amazonas , PNN, Amacayacu, Camino á San Martin. 3º41’N. 70º15’W., 150 m., Malaise, 3/1/04–3/10/04, T. Pape & D. Arias, Leg., M. 4320 (HB) . Paratype. 1 male (damaged), same data as holotype ( MLBM) .

Etymology. The name of the species is descriptive for the unique size of the style.

Remarks. D. gigantea , sp. nov. is nearest to D. permagna from Brazil ( Nielson, 1982g: 246) in which the style is twice as long as the aedeagus but has the following features that will distinguish the species: yellow and black coloration; pygofer with short caudoventral process; subgenital plate very narrow, twisted medially; aedeagal ventral process absent, with subapical, ventral flange and absence of apical stylar spine.
