43. Dilatitibialis sherry Canepari and Gordon , new species

Description. Male holotype. Length 2.6 mm, width 2.2 mm; body round, slightly elongate, convex. Dorsal surface smooth, shiny. Color black except head yellow, pronotum with large, black basomedian macula, lateral 1/5 and apical 1/5 yellow, apex of black macula entire; elytron with 2 small, pale spots, humeral spot triangular, reddish yellow spot on apical declivity irregularly rounded ( Fig. 235 ); ventral surface with antenna, mouthparts, prothoracic hypomeron, and legs yellow; abdomen with median 1/2 of ventrites 1-3 dark brown, lateral 1/4 and ventrites 4-6 yellowish brown. Head punctures small, separated by a diameter or less, each puncture as large as an eye facet; pronotal punctures larger than head punctures, separated by 1 to 2 times a diameter; elytral punctures larger than those on pronotum, separated by 1 to 3 times a diameter; metaventral punctures larger than those on elytron medially, separated by about a diameter, coarser and separated by less than a diameter toward lateral margin. Clypeus weakly emarginate apically, lateral angle rounded, surface with sparse, long pubescence. Eye canthus about 5 eye facets long, angled forward, apically rounded, yellow. Pronotum narrowed from base to apex, basal and anterior angles abrupt, lateral margin weakly rounded, basal margin with trace of bordering line medially. Epipleuron narrow, grooved, descending externally, deeply emarginate for reception of femoral apices. Protibia widely flanged, flange slightly wider than remainder of protibia, outer margin curved, smooth, sponda distinctly extended beyond protibial flange. Carinae on prosternal process widely separated at apex, convergent toward base, joined at basal 1/6 with single carina extended to basal margin of prosternum. Metaventrite with sparse setal tuft. Basal abdominal ventrite with sparse setal tuft. Abdomen with primary pores laterally between ventrites 4-5 large, extended under apical 1/2 of 4th ventrite; postcoxal line on basal abdominal ventrite slightly flattened along posterior ventrite margin, extended forward, ventrite with sparse, short pubescence and large, dense punctures; ventrites 2-4 pubescent throughout, punctures large, becoming denser toward lateral margin; 5th ventrite coarsely, densely punctured in basal 2/3, apical 1/3 depressed, feebly depressed by primary pore laterally, without tubercle on each side of middle, apical margin broadly, weakly emarginate; 6th ventrite short, narrow, weakly depressed medially, weakly emarginate apically, sparsely pubescent on each side of median depression, lateral angle abruptly rounded, surface densely punctured. Apical tergite with apex slightly emarginate. Genitalia with basal lobe slender, as long as paramere, asymmetrical, sides parallel, apex rounded; paramere wide, curved, Psc, apex with small, ventral projection ( Fig. 236, 237 ); sipho robust, strongly curved in basal 1/2, basal capsule large, inner arm long, slender, curved, apex rounded, outer arm as long as inner arm, slender, with accessory piece, basal border broadly, weakly emarginate ( Fig. 238, 239 ).

Female. Unknown.

Variation. Unknown.

Type material. Holotype male; Brazil, Rio de Janeiro, Murundu, Campos , VIII.1978, M. Alvarenga. ( CMNH).

Remarks. This nearly all black taxon is unique within this group of species having a long, slender basal lobe of the male genitalia. Similar to D. lois , D. sherry is distinguished from that species by smaller size and yellow legs. as well as different male genitalia
