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 : 23

Docalidia biarcua , sp. nov.

(Plate 1E, Figs. 33–40 )

Length. Male 5.60 mm., female unknown.

External morphology. Small, robust species. General color of dorsum dark brown throughout; eyes translucent (Plate 1E); face yellow.

Head broad, narrower than pronotum, anterior margin rounded; crown broad, about as wide as eye, produced distally about ¼ of entire length, lateral margins convergent basally, disk flat; pronotum about as long as crown, surface lightly bullated; mesonotum large, about twice as long as pronotum; forewings long, narrow, venation as in genus; clypeus long, narrow, lateral margins broadly convex, median longitudinal carina prominent; clypellus long, more than 1/3 as long as clypeus, narrow, median longitudinal ridge inflated in basal 2/3.

Male genitalia. Pygofer small, caudodorsal process moderately long, lobelike, caudoventral process reduced to small membranous lobe below base of caudodorsal process ( Fig. 33 ); right subgenital plate long, narrow, glabrous ( Fig. 34 ); righty style long, narrow with 2 separate setae between middle and apex of apophysis ( Figs. 35, 36 ); aedeagus in lateral view with shaft tubular, broadly convex, moderately long subapical seta directed basally ( Fig. 37 ), in ventral view shaft inflated medially ( Fig. 38 ); connective T-shaped, arms narrow, abruptly curved apically, medial ridge present, extended anteriorly beyond arms, stem narrow, short ( Fig. 39 ); dorsal connective short, narrow ( Fig. 40 ).

Material examined. Holotype male. COLOMBIA: Caqueta, PNN., Chiribigueta Rio Cuñare , 0º29’N. 72º37’W., 300 m., Malaise, 11/5/00-11/9/00, E. Gonzalez y M. Ospina, leg., M. 958 (HB) . Paratype. 1 male, same data as holotype ( MLBM) .

Etymology. The name is descriptive for the 2 curved setae on the apophysis of the style.

Remarks. This species has no close relatives and the absence of the caudoventral process on the pygofer and glabrous style, except for 2 subapical setae on the apophysis, will separate D. biarcua from all other species.
