5. Dilatitibialis cindy Canepari and Gordon , new species

Description. Male holotype. Length 3.5 mm, width 2.8 mm; body rounded, slightly elongate, convex. Dorsal surface weakly alutaceous, shiny. Color yellow; pronotum with black basomedian macula, lateral margin of macula briefly extended laterally, macula extended 3/4 distance to anterior pronotal margin; elytron vittate with large, black sutural vitta extended from scutellum to apex, and large, black lateral vitta extended from base across humeral callus, joining sutural vitta at apical 7/8 of elytron ( Fig. 22 ); ventral surface black except mouthparts, antenna, prothoracic hypomeron, mesepimeron, and legs yellow; abdomen with ventrites 1-4 dark brown medially, brownish yellow in lateral 1/4, ventrite 6 brownish yellow. Head punctures small, separated by about a diameter, slightly larger than an eye facet; pronotal punctures larger than head punctures, separated by a diameter or less; elytral punctures as large as on pronotum, separated by less than to 2 times a diameter; metaventral punctures dense, larger than on elytron medially, separated by a diameter or less, becoming larger toward lateral margin, separated by less than a diameter. Clypeus weakly emarginate apically, lateral angle rounded, surface with sparse, long pubescence. Eye canthus about 6 eye facets long, strongly angled forward, apically rounded, yellow. Pronotum narrowed from base to apex, basal and anterior angles abrupt, lateral margin nearly straight, basal margin without trace of bordering line. Epipleuron narrow, grooved, slightly descending externally, deeply emarginate for reception of femoral apices. Protibia strongly flanged, flange slightly wider than remainder of protibia, outer margin rounded, smooth, sponda extended slightly beyond protibial flange. Carinae on prosternal process widely separated at apex, convergent toward base, joined at basal 1/7 with single carina extended to basal margin of prosternum. Metaventrite with large setal tuft. Basal abdominal ventrite with setal tuft. Abdomen with primary pores laterally between ventrites 4-5 large, extended under apical 1/3 of ventrite 4; postcoxal line on basal abdominal ventrite rounded throughout, extended to apical margin of ventrite at middle, then broadly forward, ventrite with sparse, short pubescence and dense, coarse punctures; ventrites 2-4 sparsely pubescent throughout, punctures large, dense; 5th ventrite depressed medially in apical 1/3, densely, coarsely punctured in basal 2/3, sparsely punctured in apical 1/ 3, patch of pubescence at apex, without tubercle on each side of middle, apical margin broadly emarginate, surface sparsely punctate; 6th ventrite short, narrow, depressed medially, apical margin broadly, deeply emarginate, sparsely pubescent on each side of median depression, surface densely punctured. Apical tergite coarsely, densely punctured, pubescent, apex weakly rounded. Genitalia with basal lobe 3/ 4 length of paramere, asymmetrical, narrowed from base to oblique apex, ventral surface with rounded projection on each side; paramere Unm, straight, ventral margin produced, rounded, apex rounded ( Fig. 23, 24 ); sipho robust, strongly curved in basal 1/2, basal capsule large, inner arm long, narrow, apex truncate, outer arm wider, longer than inner arm, with accessory piece, basal border straight ( Fig. 25, 26 ).

Female. Unknown.

Variation. Unknown.

Type material. Holotype male; ( Brazil), Sta. Catarina, Lüderwaldt, Korschefsky Collection 1952 . ( USNM).

Remarks. This species is similar to D. phyllis in elytral color pattern, but is much larger, with the male pronotum having as a large, basomedian black macula, metaventrite with large setal tuft, and completely different male genitalia.
