19. Dilatitibialis emily Canepari and Gordon , new species

Description. Male holotype. Length 3.0 mm, width 2.3 mm; body rounded, slightly elongate, convex. Dorsal surface shiny except head alutaceous, dull, pronotum weakly alutaceous, shiny. Color black except pronotum with large, yellow anterolateral angle, apex with median 1/3 yellow with small, yellow emargination of median dark area; elytron with 5 yellow spots arranged in rows of 2, plus an apical spot, mediolateral spot irregularly oval, apical spot transversely oval ( Fig. 102 ); ventral surface with head, prosternum, meso- and metaventrites black, remainder of surface yellow; abdomen yellowish brown. Head punctures small, separated by a diameter or less, each puncture as large as 2 eye facets; pronotal punctures larger than head punctures, separated by less than to twice a diameter; elytral punctures larger than on pronotum, separated by 1-2 times a diameter; metaventral punctures larger than on elytron, separated by less than a diameter, larger toward lateral margin. Clypeus weakly emarginate apically, lateral angle rounded, surface with sparse, long pubescence. Eye canthus 6-7 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, descending externally, deeply emarginate for reception of femoral apices. Protibia widely flanged, flange 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 1/5 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, slightly flattened along posterior ventrite margin, extended forward, ventrite with sparse, long pubescence and large, dense punctures medially; 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, densely, finely punctured, slightly depressed by primary pore laterally, without tubercle on each side of middle, broadly emarginate apically; 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 finely, densely punctured, pubescent, apex rounded. Genitalia with basal lobe 3/4 length of paramere, asymmetrical, sides parallel, apex obliquely rounded; paramere wide, Psc, apex nearly truncate, with small, ventral projection, dorsal margin nearly straight ( Fig. 103, 104 ); sipho robust, strongly curved in basal 1/2, basal capsule large, inner arm short, slender, sides convergent, apex rounded, outer arm wider and longer than inner arm, with accessory piece, basal border broadly, deeply emarginate ( Fig. 105, 106 ).

Female. Unknown.

Variation. Length 2.7 to 3.0 mm, width 2.0 to 2.3 mm. Pronotum with size of mediobasal black area slightly variable, apex of black area entire or feebly emarginate with yellow.

Type material. Holotype male; ( Brazil), Fry Rio Jano (Rio de Janeiro), Fry Coll. 1905. 100., standing as gacognii Mls, det. R.G, Booth 2008. ( BMNH) . Paratypes; 2, 1 same data as holotype ; 1, St Paul Braz (Sâo Paulo, Brazil) (blue disc), Cleothera gacognii Muls. ( BMNH) .

Remarks. Recognized primarily by the distinctive male genitalia, D. emily has a dorsal color pattern similar to that of several other species of Dilatitibialis .
