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 : 37

Docalidia dietrichi , sp. nov.

(Plate IIF, Figs. 108–115 )

Length. Male 7.80–8.20 mm., female unknown.

External morphology. Large, robust species. General color of dorsum, yellow and black; forewings unicolorous yellow; mesontum and pronotum black, numerous small yellow spots son pronotum; crown yellow with dark brown markings; eyes grey (Plate IIF); face black, anterior margin of clypeus with transverse orange band.

Head broad, narrower than pronotum, anterior margin broadly rounded; crown broad, about as wide as eye, produced anteriorly about ¼ entire length, disk foveate on each side of middle; pronotum as long as crown, surface bullated; mesonotum half again as long as pronotum; forewings long, broad, venation typical; clypeus long, broad, lateral margins broadly convex, median longitudinal carina prominent; clypellus about 1/3 as long as clypeus, narrow, median longitudinal ridge inflated.

Male genitalia. Pygofer rectangulate, caudodorsal process long, robust, sharply pointed apically, caudoventral process reduced to semipherical lobe below base of caudodorsal process ( Fig. 108 ); left subgenital plate long, broad, glabrous ( Fig. 109 ); right style about as long as aedeagus, robust, distal 1/3 enlarged, base flanged with dense row of short setae on margins, small spine apically ( Figs. 110, 111 ); aedeagus in lateral view tubular, shaft broadly convex with medial flange, shaft expanded medially in dorsal view, toothed on margin, spine near middle of shaft ( Figs. 112–113 ); connective Y-shaped, arms with fused, broad, dorsal transverse plate ( Fig. 114 ); dorsal connective short, broad basally, tapered apically ( Fig. 115 ).

Material examined. Holotype male. COLOMBIA: Putamayo, PNN, La Paya, Cabaña La Paya , oº2’S. 75º12’W., 330 m., Malaise, 7/15/02–8/1/02, A. Morales, leg. M. 3324 (HB) . Paratype. 1 male, same data as holotype except 7/15/02–7/31/02, M. 3322 ( MLBM) .

Etymology. This species is named in honor of Chris Dietrich, Illinois Natural History Survey, for his pioneer studies on phylogeny of the Membracoidea which are well recognized and acknowledged.

Remarks. This species is similar to D. triangulata (Nielson, 192h: 292) in stylar and aedeagal configurations but can be separated by the long, robust process, large semispherical lobe on the caudal margin of the pygofer and the glabrous, more slender subgenital plate.
