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 : 40

Docalidia exilitis , sp. nov.

(Plate IIH, Figs. 125–133 )

Length. Male 6.00–6.20 mm., female unknown.

External morphology. Small, robust species. General color of dorsum dark brown to black with large triangulate, translucent spot on middle of forewings, veins marked with small, flavous spots; eyes dark brown (Plate IIH); face black.

Head broad, narrower than pronotum, anterior margin broadly rounded; crown broad, slightly narrower than eye, produced slightly beyond anterior margin of eyes, elevated; eyes large, globular, occupying more than 2/3 of entire dorsal aread of head; pronotum about as long as crown; mesonotum large, about half again as long as pronotum; forewings long, broad, venation typical; clypeus long, narrow, lateral margins convex, median longitudinal carina prominent; clypellus about 1/3 as long as clypeus, lateral margins flared distally.

Male genitalia. Pygofer in lateral view subquadrate with very long caudodorsal process, process nearly as long as body of pygofer, triangulate apically, caudoventral process reduced to small lenticular lobe below base of caudodorsal process ( Fig. 125 ); segment X long, narrow with oblanceolate ventral process ( Fig. 126 ); right subgenital plate long, narrow, broadly convex on outer lateral margin, glabrous ( Fig. 127 ); right style long, longer and more robust than aedeagus, distal 1/3 dolobrated lobe, toothed laterally, with single spine apically in lateral view ( Fig. 128 ), in dorsal view slender medially, distal lobe narrowed ( Fig. 129 ); aedeagus slender, tubular, broadly convex in lateral view, small ventral subapical spine, gonopore supramedial ( Figs. 130, 131 ); connective broadly Yshaped, arms narrow, membrane absent, medial ridge extending beyond anterior margin of arms, stem long, broad ( Fig. 132 ); dorsal connective moderately long, base broad ( Fig. 133 ).

Material examined. Holotype male. BOLIVIA: Sta. Cruz, Buena Vista , 26 Feb–8 Mar 1999, Mal. Trp. [Malaise trap], F. Parker ( NMNH) . Paratype. 1 male, same data as holotype exept 13 Feb 1999, F. D. Parker ( USU) .

Etymology. The name is descriptive for the narrow, lenticular lobe below the base of the caudodorsal process of the pygofer.

Remarks. From D. morosa ( Nielson, 1990:228) to which it is similar to configuration of the aedeagus and style, exilitis , sp. nov. can be distinguished by absence of the caudoventral pygofer process, presence of lenticular lobe below base of caudodorsal process, oblanceolate ventral process of segment X and much narrower subgenital plate.
