35. Dilatitibialis grace Canepari and Gordon , new species

Description. Male holotype. Length 2.3 mm, width 1.8 mm; body elongate, convex. Dorsal surface smooth, shiny. Color black except head yellow, pronotum with black basomedian macula extended 3/4 distance to anterior margin, apex of macula irregularly entire; elytron with 2 pale spots, humeral spot small, yellow, triangular, discal spot large, reddish yellow, oval ( Fig. 190 ); ventral surface with antenna, mouthparts, prothoracic hypomeron, and legs yellow; abdomen yellowish brown. Head punctures small, separated by a diameter or less, each puncture about 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 3 times a diameter; metaventral punctures larger than those on elytron medially, separated by a diameter or less, 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 slightly rounded, basal margin without trace of bordering line. Epipleuron narrow, grooved, not descending externally, deeply emarginate for reception of femoral apices. Protibia narrowly flanged, flange narrower than remainder of protibia, outer margin slightly curved, smooth, sponda distinctly extended 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 without setal tuft. Basal abdominal ventrite without setal tuft. Abdomen with primary pores laterally between ventrites 4-5 large, extended under apical 1/3 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 medially, small, dense, 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 broadly emarginate, sparsely pubescent on each side of median depression, lateral angle abruptly rounded, surface densely punctured. Apical tergite with apex broadly emarginate. Genitalia with basal lobe short, wide, 3/4 as long as paramere, asymmetrical, sides convergent from near base to apex, apex rounded; paramere wide, curved, Psc, apex with small, ventral projection ( Fig. 191, 192 ); sipho robust, strongly curved in basal 1/2, basal capsule large, inner arm long, wide, apex rounded, outer arm longer than inner arm, outer margin sinuate, with accessory piece, basal border broadly emarginate ( Fig. 192, 193 ).

Female. Unknown.

Variation. Unknown.

Type material. Holotype male; Bolivia, Santa Cruz Dept., 3.7 km SSE Buena Vista, Hotel Flora y Fauna - 400m, 17 o 29’S 63 o 33’W, A. Cline & J. Wappes, FIT in sandy forest. ( CSCA).

Remarks. Dilatitibialis grace is recognized by the small size, 2 pale spots on each elytron, humeral spot yellow, large discal spot reddish yellow, elongate, and sinuate outer margin of siphonal capsule.
