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 : 52

Docalidia mckameyi , sp. nov.

(Plate IIIG, Figs. 184–191 )

Length. Male 7.80 mm., female unknown.

External morphology. Moderately large, robust species. General color dark brown to black, with 2 broad, translucent transverse orange bands on forewings, small orange spot on mesonotum, pronotum and crown; eyes dark brown (Plate IIIG); face black, suffused with orange markings.

Head small, much narrower than pronotum, anterior margin rounded; crown broad, about as wide as eye, lateral margins abruptly convergent basally; pronotum about ¼ as long as crown, surface bullated, mesonotum moderately large, less than twice as long as pronotum; clypeus broad, lateral margins convex, with prominent, median longitudinal carina; clypellus narrow, less than 1/3 as long as clypeus, distal 1/3 flared.

Male genitalia. Pygofer in lateral view narrowly triangulate, caudodorsal process moderately long, broad basally, digitate, caudoventral process absent, caudal margin narrow, membranous ( Fig. 184 ); right subgenital plate long, broad subbasally, tapered distally, glabrous ( Fig. 185 ); right style very long, longer than aedeagus, robust, long stout spines below middle of apophysis, extending subbasally, row of fine hair-like setae distad of stout spines ( Figs. 186, 187 ); aedeagus narrow, tubular, with extremely long subapical, slender process on ventral margin, directed basally, gonopore with lateral flange (Figs. 188,189); connective T-shaped, membrane absent, medial ridge extending beyond anterior margin of arms, stem long, stem and ridge enclosed by membrane ( Fig. 190 ); dorsal connective moderately long, strapped shape, broad basally, tapered distally ( Fig. 191 ).

Material examined. Holotype male. ECUADOR: Napo Yasuni Res. Sta., 250 m., 19–30 Oct 1988, W. J. Hanson, 6º36’W 0º38S ( NMNH).

Etymology. The name is patronymic in honor of Stuart McKamey, Research Entomologist, USDA/Systematic Entomology Laboratory, Washington, D. C. for his fine work on resolution of nomenclature problems, research on taxonomy and updating a catalogue of genera and species of the Cicadellidae .

Remarks. This species is unique and has no known close relatives. The extremely long, aedeagal ventral process (longest among all known species) and the row of stout spines followed by a short row of fine, hair-like setae on the style will separate mckameyi , sp. nov. from all other known species in the genus.
