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 : 37-40

Docalidia dmitrievi , sp. nov.

(Plate IIG, Figs. 116–124 )

Length. Male 8.80 mm., female unknown.

External morphology. Large, robust species. General color of dorsum unicolorous brown except for mesonotum, black; pronotum with numerous contiguous yellow spots; crown yellow with black markings on disk; eyes grey (Plate IIG); face black with few small yellow spots on clypeus.

Head narrower than pronotum, anterior margin broadly rounded; crown broad, as wide as eye, produced anteriorly about ¼ of entire length, disk foveate on each side of middle; eyes large, semiglobular; pronotum about equal to length of crown, surface bullated; mesonotum very large, over twice as long as pronotum; forewings long, broad, venation typical; clypeus long, broad, lateral margins broadly convex, median longitudinal carina prominent; clypellus short, about 1/3 as long as clypeus, narrow, lateral margins constricted, median longitudinal ridge inflated from base to apex.

Male genitalia. Pygofer in lateral view large, triangulate, caudodorsal process moderate long, narrow, segmented medially, caudoventral process reduced to small semispherical lobe below base of process ( Fig 116 ); right subgenital plate long, broad, outer lateral margin broadly convex, glabrous; ( Fig. 117 ); right style long, about as long as aedeagus, robust, in dorsal view distal 1/3 expanded laterally, densely setaceous along outer lateral margin, in lateral view with densely setaceous, longitudinal band extending beyond lateral margin ( Figs. 118, 119 ); aedeagus long, tubular, sinuate in lateral view, shaft inflated medially in ventral view, gonopore cryptic, ventral process near middle of shaft, short, very straight, directed basally ( Figs. 120, 121 ); connective widely T-shaped, arms broad, membrane absent, paired ridges extending beyond anterior margin, stem broad basally, converging distally ( Fig. 122 ); dorsal connective short, broad basally, tapered apically ( Fig. 123 ), narrowed throughout in lateral view ( Fig. 124 ).

Material examined. Holotype male. COLOMBIA: Amazonas , PNN, Amacayacu Matamata, 3º41’S. 70º15’W., 150 m., pantrap, 3/1/04–3/10/04, [ T.] Pape & D. Arias, leg. M. 4330 (HB) . Paratype. 1 male, same date as holotype except Amacayacu, Camino á San Martin, 3º41’N 70º15’W., 150m, Malaise, 3/1/04–3/10/ 04, T. Pape & D. Arias, leg. , M. 4320 ( MLBM).

Etymology. This species is named in honor of Dmitry A. Dmitriev, Illinois Natural History Survey, for his work on taxonomy of the Palaearctic fauna and contributions on phylogeny of Cicadellidae .

Remarks. From D. multispiculata ( Nielson, 1979b:247) to which it similar in some stylar and aedeagal features, dmitrievi , sp. nov. can be separated by the style in lateral view with a unique, medial, longitudinal band of dense setae on the apical 1/3 of the apophysis that extends beyond its margin, by the absence of spicules on the aedeagal shaft and the long, narrower, glabrous subgenital plate.
