Bertawolia lata sp. nov.

( Figs 19 −36)

Diagnosis. Head (Fig. 21) with black macula on crown-face transition, extending ventrally over dorsal portion of frons. Subgenital plate (Fig. 23), in lateral view, short, not widened apically, produced posterad only as far as basal third of pygofer; apex rounded. Aedeagus (Fig. 27), in lateral view, with shaft narrow, strongly curved dorsally in right angle; dorsal margin deeply excavated; in posterior view (Fig. 28), broadened toward apex with apical margin undulated. Female sternite VII ( Fig. 29 ) with posterior margin excavated, mid-portion with short rounded lobe.

Color. Head ( Figs 19 −21) yellow, with a large black macula on crown-face transition between ocelli, and ex- tending ventrolaterally to almost eye inner margin, or surrounding the ocellus (in more melanic specimens, like in fig. 21), median portion of macula forming triangular projection extending ventrally over dorsal portion of frons. Pronotum ( Fig. 19 ), in dorsal view, black, with yellow irregular area near anterior margin or almost completely yellow with posterior margin black; lateral margin yellow; in lateral view (Fig. 20) proepimeron yellow. Mesonotum ( Fig. 19 ) with lateral angles black, median portion brown, lateral margins and scutellum yellow. Forewing ( Figs 19 , 20) light-yellow and traslucent; clavus with anterior half brown continuous with black macula medially; apex black. Legs yellow.

Measurements (mm). Holotype male: total length 3.5. Paratypes (male), 3.2−3.5; (female), 3.6−3.9.

Description. Head ( Figs 19 −21), with surface of crown and crown-face transition with inconspicuous trans- verse striae. Other characteristics as in the previous description.

Male terminalia. Sternite VIII (Fig. 22) strongly convex, longer than wide, slightly longer than sternites VII and VI combined; ventral surface with many small setae; lateral angles rounded; posterior margin almost straight. Valve (Fig. 23) broadly fused laterally to pygofer. Pygofer (Fig. 23), in lateral view, higher near basal portion, without processes; dorsal margin deeply notched on median third; ventral margin rounded on basal half and slightly excavated medially, bent inwards; apex truncated; macrosetae dispersed on apical fourth; in ventral view (Fig. 24), inner margin sinuous, with thin setae on basal half and many short macrosetae on apical third. Anal tube (Figs 23, 24) membranous, without processes. Subgenital plate (Fig. 23), in lateral view, short, not widened apically, overlapping pygofer laterally, produced posteriorly only as far as basal third of pygofer; basal portion strongly produced dorsally inwards of pygofer; ventral surface with few oblique striae and without setae; apex rounded. Connective (Fig. 25), in posterior view, U-shaped, narrow, with elongated arms. Style (Fig. 26), in lateral view, elongated, almost straight, with small truncated lobe at point of articulation with connective; apical portion slightly curved dorsally; apex only slightly expanded, foot-shaped. Aedeagus (Fig. 27), in lateral view, with preatrium developed, produced anterad between arms of connective; atrium wide; ventral margin notched at point of articulation with connective; shaft narrow, strongly curved dorsally in right angle; dorsal margin deeply excavated; in posterior view (Fig. 28), expanded laterally, broadened toward apex; lateral margin carinate; apical margin undulated; gonopore apical.

Female terminalia. Sternite VII ( Fig. 29 ) ca. two times wider than long; ventral surface with short setae; posterior margin excavated, mid-portion with short rounded lobe. Internal sternite VIII membranous. Pygofer ( Fig. 29 −30) with short macrosetae, except on anterodorsal portion; ventral margin broadly rounded; apex truncated with rounded protrusion near ventral margin. Ovipositor (Fig. 30) slender, curved dorsad, slightly surpassing pygofer apex. First valvifer (Fig. 31) trapezoid, slightly higher than long; anterior and dorsal margins approximately straight; posteroventral angle rounded. First valvula (Fig. 31) 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. 32) with ventral sculpture present only near apex, continuous with the dorsal sculpture, apex tapered and acute. Second valvula (Fig. 33) ca. 11 times longer than high; dorsal and ventral margins, parallel; dorsal margin with two distinct subapical teeth widely spaced; apical portion (Fig. 34) with rounded denticles from second subapical tooth to apex; apex rounded, with denticles on ventral margin. Second valvifer ca. 2.7 times higher than long. Gonoplac (Fig. 35) 4.2 times longer than high; dorsoapical margin long, with half of length of gonoplac, straight, almost parallel to ventral margin; ventral margin (Fig. 36) broadly rounded, with spaced setae near ventral margin; apex rounded.

Etymology. The specific epithet, lata , a Latin adjective, refers to the apically broadened aedeagus, in posterior view.

Notes. B. lata sp. nov. can be easily separated from other species by the subgenital plate not widened apically and the aedeagus, in posterior view, broadened distally with the apical margin undulated.
