33. Dilatitibialis carmen Canepari and Gordon , new species

Description. Male holotype. Length 2.6 mm, width 2.0 mm; body rounded, slightly elongate, convex. Dorsal surface weakly alutaceous, shiny. Color yellow except pronotum with large, narrow, light brown mediobasal spot, spot extended nearly 3/4 distance to anterior pronotal margin, narrowly, deeply emarginate with yellow medially; elytron with 3 large, light brown spots and apical margin narrowly brown, humeral spot irregularly rectangular, spot on sutural margin extended from basal 1/5 to apex, narrowed from base to apex, connected to mate on opposite elytron, spot on apical declivity irregularly obliquely oval ( Fig. 178 ); ventral surface with head, prosternum, meso- and metaventrite pale reddish yellow, legs yellow; abdomen pale reddish yellow. Head punctures small, separated by less than a diameter, each puncture about as large as an eye facet; pronotal punctures as large as head punctures, separated by 2 to 4 times a diameter; elytral punctures as large as on pronotum, separated by 2 to 4 times a diameter; metaventral punctures slightly larger than those on elytron medially, separated by less than a diameter, coarser and separated by a diameter or less toward lateral margin. Clypeus truncate 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 rounded, basal margin without trace of bordering line. Epipleuron narrow, grooved, slightly descending externally, deeply emarginate for reception of femoral apices. Protibia narrowly flanged, flange narrower than remainder of protibia, outer margin curved, smooth, sponda weakly extended beyond protibial flange. Carinae on prosternal process widely separated at apex, convergent toward base, joined at basal 5/6, with 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 ventrite 4; postcoxal line on basal abdominal ventrite flattened along posterior ventrite margin, weakly extended forward, ventrite with sparse, short pubescence and large, dense punctures; ventrites 2-4 pubescent throughout, punctures large; ventrite 5 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; ventrite 6 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 weakly rounded. Genitalia with basal lobe short, wide, 3/4 as long as paramere, asymmetrical, sides straight, apex rounded; paramere wide, curved, Psc, apex with small, ventral projection ( Fig. 179, 180 ); sipho robust, strongly curved in basal 1/2, basal capsule large, inner arm long, slender, narrowed medially, apex obliquely truncate, outer arm slightly longer than inner arm, with accessory piece, basal border broadly, weakly emarginate ( Fig. 181, 182 ).

Female. Similar to male except head with clypeus brown, frons and vertex pale brown adjacent to eye. Genitalia with spermathecal capsule short, wide, curved medially; bursal cap with 3 faintly defined arms, apical strut long, widened from base to laterally flattened apex ( Fig. 183 ).

Variation. Length 2.5 to 2.6 mm, width 1.9 to 2.0 mm. Elytral spots vary slightly in size.

Type material. Holotype male; ( Venezuela), Petare-Guarenas. 3-18-‘38, Venez #58, CHBallou, Miller. ( USNM) . Paratypes; 2, 1, same data as holotype ( USNM) ; 1, Venezuela, Aragua, Ocumare De La Costa 2kmN, 12 June 1976, A. S. Menke & D. Vincent ( USNM) .

Remarks. The dorsal color pattern is distinctive for this species. In addition, the basal abdominal ventrite has a postcoxal line with apex extremely short, indistinct.
