Bertawolia grazielia  sp. nov.

( Figs 1View FIGURES 1 −18)

Diagnosis. Head (Fig. 3) with black macula on crown-face transition not extending ventrally over dorsal portion of frons. Subgenital plate (Fig. 5), very wide; ventral surface with several oblique striae; apex broadly rounded. Aedeagus (Fig. 9), in lateral view, robust, wide at base of shaft; in posterior view (Fig. 10), expanded laterally, wider medially and tapered apically. Female sternite VII ( Fig. 11View FIGURES 11) with posterior margin slightly excavated, almost straight.

Color. Head ( Figs 1View FIGURES 1 −3) yellow, with a large black macula on crown-face transition between ocelli, extending ventrolaterally to almost eye inner margin (Fig. 3), or surrounding ocellus (in more melanic specimens). Pronotum ( Fig. 1View FIGURES 1), in dorsal view, frequently brown, sometimes dark-brown or black; lateral margin yellow. Mesonotum ( Fig. 1View FIGURES 1) frequently brown, sometimes dark-brown; lateral margins and scutellum yellow. Forewing ( Figs 1View FIGURES 1, 2) light-yellow and translucent; clavus with anterior half brown, apex black. Legs yellow.

Measurements (mm). Holotype male: total length 3.9. Paratypes (male), 3.6−4.0; (female), 4.1−4.4.

Description. Body ( Figs 1View FIGURES 1, 2) ovate, not depressed dorsoventrally. Head ( Fig. 1View FIGURES 1), in dorsal view, very short, median length of crown one-tenth of interocular width; transocular width nine-tenths humeral width of pronotum; anterior and posterior margins parallel and broadly rounded; crown surface smooth; ocelli not visible dorsally. Head (Fig. 2), in lateral view, with crown-face transition broadly rounded, smooth; frons slightly inflated; clypeus almost flat. Head (Fig. 3), in ventral view, ocelli on anterior margin, mesad of antennal pits and distant from eyes; frons with inconspicuous transverse striae, lateral margins strongly convergent ventrally; frontogenal suture extending to antennal ledges; antennal ledge carinate and slightly oblique, not concealing antennal base; antenna short, length approximately one third width of head; gena broad, with small setae; ventrolateral margin broadly rounded, completely concealing proepisternum; maxillary plate produced ventrally as far as clypeus apex; epistomal suture distinct and complete; lorum with subgenal suture rounded, extended nearly to mid-length of lateral margin of frons; clypeus slightly longer than wide, lateral margins weakly convergent apically, apex carinate and straight.

Pronotum ( Fig. 1View FIGURES 1), in dorsal view, with anterior margin broadly rounded, posterior margin slightly excavated; surface without setae, with transverse striae, except on anterior third; lateral margins convergent anterad, carinate, slightly shorter than eye length; in lateral view (Fig. 2) convex and declivous anterad. Exposed part of mesonotum and scutellum ( Fig. 1View FIGURES 1) as long as pronotum; surface with transverse striae; scutellum flat.

Forewing ( Figs 1View FIGURES 1, 2) with many small erect setae, venation obscure; clavus truncate apically; vein separating appendix and first apical cell evanescent apically, appendix and first apical cell membranous, glabrous; 3 closed anteapical cells and 4 apical cells (R1 vein absent).

Profemur moderately elongated, 2.7 times longer than high; PD, AD and AM rows undifferentiated, with scattered setae, PD1 and AD1 setae developed and AM1 absent; IC row formed by double row of fine setae, continuous with AV row; AV and PV rows formed by several fine setae. Protibia, in cross-section, almost circular, with longitudinal carina adjacent to PD row; dorsal surface flattened; AV row formed by short, thin setae in the basal half and short, robust setae distally; AD row consisting of only undifferentiated setae; PD row with 3 long setae intercalated by undifferentiated setae; PV row with 5−6 setae. Hind leg with femoral setal formula 2:2:1; PD2 reduced in size; metatibia PD, AD and AV rows with 12−14, 10 and 9−10 macrosetae respectively; AD row without intercalary setae between macrosetae; PV row with setae of apical portion intercalating 1 longer and thicker seta and 3−4 shorter and thinner setae, ending with 2 very short, thin setae; first tarsomere ventral surface with two longitudinal rows of 5−6 short, simple (non-cucullate) setae; pecten with 4 platellae flanked by tapered lateral setae; second tarsomere pecten with 2 platellae flanked by tapered lateral setae.

Sternite VIII (Fig. 4) strongly convex, longer than wide, slightly longer than sternites VII and VI combined; ventral surface with many small setae; posterior margin rounded, median third slightly more produced posterad than near lateral angles and bent inwards. Valve (Fig. 5) broadly fused laterally to pygofer. Pygofer (Fig. 5), in lateral view, higher near basal portion, without processes; dorsal margin deeply notched on median third; ventral margin almost straight, bent inwards; apex broad, truncated; macrosetae dispersed on apical fourth; in ventral view (Fig. 6), inner margin sinuous, with thin setae on anterior half and many short macrosetae on apical third. Anal tube (Figs 5, 6) membranous, without processes. Subgenital plate (Fig. 5), in lateral view, very wide, overlapping pygofer laterally, produced posteriorly as far as half length of pygofer; ventral surface with several oblique striae and without setae; apex broadly rounded. Connective (Fig. 7), in posterior view, U-shaped, narrow, with elongated arms. Style (Fig. 8), in lateral view, elongated, almost straight, with dorsal rounded lobe at point of articulation with connective; apical portion slightly curved dorsally; apex expanded, foot-shaped. Aedeagus (Fig. 9), in lateral view, robust; preatrium developed, produced anterad between arms of connective; atrium very wide; ventral margin notched at point of articulation with connective; shaft flattened laterally, strongly curved dorsally and tapered apically; in posterior view (Fig. 10), expanded laterally, wider medially and tapered apically; lateral margin carinate; gonopore apical.

Female terminalia. Sternite VII ( Fig. 11View FIGURES 11), in ventral view, ca. two times wider than long; ventral surface with short setae; posterior margin slightly excavated, almost straight. Internal sternite VIII membranous. Pygofer ( Figs 11View FIGURES 11, 12) with short macrosetae, except on anterodorsal portion; ventral margin broadly rounded; apex truncated. Ovipositor (Figs 12, 13, 15) slender, curved dorsad, slightly surpassing pygofer apex. First valvifer (Fig. 13) trapezoid, slightly higher than long; anterior and dorsal margins approximately straight; posteroventral angle broadly rounded. First valvula (Fig. 13) with dorsal and ventral margins, almost parallel, slightly convergent apically, ca. 9 times longer than high; ventral interlocking device long, extending over basal two-third; dorsal sculpturing area areolate on apical two-thirds; apical portion (Fig. 14) with ventral sculpture present only near apex, continuous with the dorsal sculpture, apex tapered and acute. Second valvula (Fig. 15) ca. 11 times longer than high; dorsal and ventral margins, parallel; dorsal margin with two distinct subapical teeth widely spaced; apical portion (Fig. 16) with rounded denticles from second subapical tooth to apex; apex rounded, with denticles on ventral margin. Second valvifer (Fig. 17) ca. 2.7 times higher than long. Gonoplac (Fig. 17) 4.6 times longer than high; dorsoapical margin long, with half of length of gonoplac, straight, almost parallel to ventral margin; ventral margin (Fig. 18) broadly rounded, with spaced setae near ventral margin; apex rounded.

Etymology. The new species name refers to the genus of the host plant on which the leafhopper was collect- ed.

Notes. B. grazielia  sp. nov. is more similar to B. lata  sp. nov. in having the ventral margin of the pygofer not strongly excavated. The subgenital plate very wide with apex broadly rounded and the aedeagus robust, in lateral view, differs B. grazielia  sp. nov. from the other species of the genus.
