57. Dilatitibialis elaine Canepari and Gordon , new species

Description. Male holotype. Length 3.0 mm, width 2.4 mm; body rounded, slightly elongate, convex. Dorsal surface weakly alutaceous, somewhat shiny. Color brown except head yellow, pronotum with brown, basomedian macula extended 3/4 distance to anterior margin, apex of macula weakly, narrowly emarginate with yellow; elytron with 5 small yellow spots, humeral spot obliquely oval, mediolateral spot projected inward, apical spot transversely oval ( Fig. 313 ); ventral surface with antenna, mouthparts, prothoracic hypomeron, and legs except trochanters yellow; abdomen brownish yellow. 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 a diameter of less; elytral punctures larger than on pronotum, separated by 1 to 3 times a diameter; metaventral punctures larger than on elytron medially, separated by 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 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 nearly straight, sponda distinctly extended beyond protibial flange. Carinae on prosternal process narrowly 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 small, extended under apical 1/4 of 4th ventrite; postcoxal line on basal abdominal ventrite rounded throughout, 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, with nonciliate 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 weakly emarginate. Genitalia with basal lobe long, slender, as long as paramere, asymmetrical, sides parallel, apex bent to one side; paramere narrowed medially, dorsal margin broadly emarginate, apex rounded ( Fig. 314, 315 ); sipho robust, strongly curved in basal 1/2, basal capsule large, inner arm short, wide, curved, apex truncate, outer arm wider and longer than inner arm, with accessory piece, basal border broadly, shallowly emarginate ( Fig. 316, 317 ).

Female. Unknown.

Variation. None observed.

Type material. Holotype male; (Brasil), Cantareira , Sao Paulo, 17.II.1962, J. Halik, 19011, BRASIL, Halik 1966 Collection. ( USNM) . Paratype; 1, (Brazil), Macaé de Sima- 1500m, Nova Friburgo, Rio de Janeiro - Brasil , 1-15/I/2006, P. Grossi, col, Armadilha Interceptadora de Vôo ( FIT) ( DZUP) .

Remarks. Dilatitibialis elaine has the same dorsal color pattern as do several other Dilatitibialis species , but the presence of tubercles on the male 5th ventrite and male genitalia with a long, apically bent basal lobe immediately distinguish it from all others.
