Description. Male holotype. Length 2.8 mm, width 2.4 mm; body round, slightly elongate, convex. Dorsal surface with head smooth, shiny, pronotum, elytron weakly alutaceous, shiny. Color black except head yellow, pronotum yellow with large, black basomedian macula extended 2/3 distance to anterior margin, apex of macula weakly emarginate with yellow medially; elytron with 3 small, yellow spots, humeral spot small, triangular, discal spot large, ovate, apical spot large, irregularly triangular ( Fig. 229 ); ventral surface with antenna, mouthparts, prothoracic hypomeron, legs yellow; abdomen dark brown except ventrites 5-6 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 a diameter or less; elytral punctures larger than those on pronotum, separated by 1 to 2 times a diameter; metaventral punctures larger than those on elytron medially, separated by less than a diameter, coarser and separated by a diameter or less toward lateral margin. Clypeus weakly emarginate apically, lateral angle rounded, surface with sparse, long pubescence. Eye canthus about 6 eye facets long, angled forward, apically rounded, yellow. Pronotum narrowed from base to apex, basal and anterior angles abrupt, lateral margin rounded, basal margin with trace of bordering line medially. Epipleuron narrow, grooved, weakly descending externally, deeply emarginate for reception of femoral apices. Protibia widely flanged, flange slightly wider than remainder of protibia, outer margin curved, smooth, sponda slightly 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 without setal tuft. Basal abdominal ventrite without 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, depressed medially, apical margin weakly emarginate, sparsely pubescent on each side of median depression, lateral angle abruptly rounded, surface densely punctured. Apical tergite with apex slightly convex. Genitalia with basal lobe slender, about as long as paramere, asymmetrical, sides parallel, apex rounded; paramere wide, curved, Psc, apex with small, ventral projection ( Fig. 230, 231 ); sipho robust, strongly curved in basal 1/2, basal capsule large, inner arm long, slender, curved, apex rounded, outer arm wide, shorter than inner arm, with accessory piece, basal border broadly, weakly emarginate ( Fig. 232, 233 ).

Female. Similar to male except head dark brown, pronotum with median macula extended to anterior pronotal margin, elytron without humeral spot. Genitalia with spermathecal capsule long, slender, weakly widened from base to apex; bursal capsule without sclerotized arms, apical strut long, curved, enlarged in apical 1/2 ( Fig. 234 ).

Variation. Length 2.7 to 3.3 mm, width 2.4 to 2.8 mm. Elytral spots may vary in size, a single paratype has discal and apical spots weakly connected.

Type material. Holotype male; ( Brazil), Fry , RioJan, Fry Coll. 1905. 100. 17831. ( BMNH) . Paratypes; 8, 2, same data as holotype ( BMNH) ; 1, 57 71, quadrisignatat Dej. Cayen. Bresil (green label, handwritten) ( BMNH) ; 1, Bras , Sammlung Cl. Müller ( CAS) ; 2, Brazil, Chapada , Acc.No. 2966, Nov. ( CMNH) ; 2, Brazil, Rio de Jan. , Acc.No. 2966, Oct., Nov. ( CMNH) .

Remarks. Dilatitibialis kim is somewhat similar to D. grace in dorsal color pattern, but D. kim has an apical spot on each elytron, is much larger, and male genitalia are not at all similar.
