30. Dilatitibialis tracy Canepari and Gordon , new species

Description. Male holotype. Length 2.5 mm, width 1.7 mm; body elongate, convex. Dorsal surface with head smooth, shiny, pronotum and elytron weakly alutaceous, shiny. Color black except head yellow, pronotum with lateral 1/4 and anterior 1/6 yellow, apex of black median macula entire, not emarginate with yellow; elytron with 3 small, yellow spots, 2 basal spots, 1 discal, without lateral spot, scutellar spot irregularly triangular, discal spot irregularly obliquely oval, apical spot transversely oval ( Fig. 162 ); ventral surface with antenna, mouthparts, prothoracic hypomeron, and legs yellow; abdomen brown medially, lateral 1/4 and ventrites 5-6 yellowish brown. Head punctures small, separated by a diameter or less, each puncture about as large as an eye facet; pronotal punctures slightly larger than head punctures, separated by 1-2 times a diameter; elytral punctures as large as those on pronotum, separated by 1 to 3 times a diameter; metaventral punctures larger than those on elytron medially, separated by 1 to 2 times a diameter, becoming coarser, separated by less than a diameter laterally. Clypeus weakly emarginate apically, lateral angle rounded, surface with sparse, long pubescence. Eye canthus about 4 eye facets long, angled forward, apically rounded, yellow. Pronotum narrowed from base to apex, basal and anterior angles abrupt, lateral margin rounded, basal margin without trace of bordering line. Epipleuron narrow, grooved, weakly descending externally, deeply emarginate for reception of femoral apices. Protibia narrowly flanged, flange as wide as remainder of protibia, outer margin curved, smooth, sponda feebly extended beyond protibial flange. Carinae on prosternal process narrowly separated at apex, convergent toward base, joined at basal 1/4 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 small, extended under apical 1/4 of 4th ventrite; postcoxal line on basal abdominal ventrite rounded along posterior ventrite margin, extended forward, ventrite with sparse, short pubescence and large, sparse punctures medially; ventrites 2-4 pubescent throughout, punctures large medially, small, dense laterally, becoming denser toward lateral margin; 5th ventrite coarsely, sparsely 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 broadly emarginate, sparsely pubescent on each side of median depression, lateral angle abruptly rounded, surface feebly punctured. Apical tergite with apex weakly rounded. Genitalia with basal lobe short, wide, 3/4 as long as paramere, asymmetrical, sides weakly rounded, apex rounded; paramere wide, curved, Psc, apex with small, ventral projection, trabes straight ( Fig. 163, 164 ); sipho robust, strongly curved in basal 1/2, basal capsule large, inner arm long, slender, apex rounded, outer arm slightly longer than inner arm, with accessory piece, basal border broadly, deeply emarginate ( Fig. 165, 166 ).

Female. Unknown.

Variation. Unknown.

Type material. Holotype male; Brazil, Serra Caraca - 1380m, MG-Brasil - XI - 961, Kloss, Lenko, Martins & Silva col. ( MZSP).

Other specimens. 3. ( Brazil) Espiritu Santo; Rio de Janeiro. ( BMNH) ( ZMHB)

Remarks. This species is superficially similar to the preceding 2, but the body is more, elongate, it has 4 yellow spots on each elytron, and the eye canthus is short, as long as 4 eye facets. Male genitalia of all 3 species are extremely similar, but external characters differ as stated. Specimens listed under “Other specimens” agree well with the holotype of D. tracy in external appearance, but male genitalia differ slightly.
