3. Dilatitibialis tina Canepari and Gordon , new species

Description. Male holotype. Length 2.7 mm, width 2.3 mm; body rounded, slightly elongate, convex. Dorsal surface shiny, lacking alutaceous sculpture. Color dark brown except head yellow; pronotum yellow with basal margin and 2 triangular, median spots in apical 1/2 dark brown; elytron with 5 large, yellow spots arranged in rows of 2 each with single apical spot, humeral and mediolateral spot narrowly connected along lateral margin ( Fig. 13 ); ventral surface with mouthparts, antenna, prothoracic hypomeron, legs yellow; abdomen brownish yellow. Head punctures small, separated by about a diameter, slightly larger than an eye facet; pronotal punctures larger than head punctures, separated by a diameter or less; elytral punctures larger than on pronotum, separated by less than to twice a diameter; metaventral punctures larger than on elytron, separated by less than a diameter, becoming large, nearly contiguous 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 bordering line. Epipleuron narrow, grooved, deeply emarginate for reception of femoral apices. Protibia weakly flanged, flange about 1/2 width of remainder of protibia, outer margin slightly rounded, smooth, sponda distinct, extended slightly 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 with large, sparse setal tuft. Basal abdominal ventrite without setal tuft. Abdomen with primary pores laterally between ventrites 4-5 small, extended under apical 1/4 of ventrite 4; postcoxal line on basal abdominal ventrite rounded, extended to apical margin of ventrite at middle, slightly flattened along margin, then broadly forward, ventrite with sparse, short pubescence and dense, coarse punctures medially; ventrites 2-4 densely pubescent throughout, punctures small, dense medially, becoming denser toward lateral margin; 5th ventrite depressed medially in apical 1/2, patch of long pubescence on each side of median depression, without tubercle on each side of middle, apical margin broadly emarginate, surface nearly impunctate; 6th ventrite short, narrow, depressed medially, apical margin broadly emarginate, sparsely pubescent on each side of median depression, surface nearly impunctate. Apical tergite coarsely, densely punctured, pubescent, posterolateral angle abruptly rounded, densely, finely punctured. Genitalia with basal lobe shorter than paramere, asymmetrical, narrowed from base to obliquely truncate apex; paramere Unm, straight, unmodified, widest at apex, apex rounded ( Fig. 14, 15 ); sipho lost.

Female. Similar to male except head black, pronotum entirely black except lateral 1/6 yellow. Genitalia with spermathecal capsule short, wide, cornu slightly widened; bursal cap oval, with 3 distinct arms, apical strut short, slender, weakly spatulate at apex in lateral view ( Fig. 16 ).

Variation. Length 2.4 to 2.7 mm, width 1.6 to 2.3 mm.

Type material. Holotype male; Brazil, St Paul Bras (Sao Paulo) (handwritten on blue disc), standing as Cleothera jocosa Muls. , det R. G. Booth 2008. ( BMNH) . Paratypes; 2, 1, same data as holotype ( BMNH) ; 1, 255 8023, Cleothera jocosa , m Brasil, Named by Mulsant ( BMNH) .

Remarks. This species shares the same dorsal color pattern with some other species of Dilatitibialis , but the unmodified male genitalia are unique.

Mulsant (1850) stated that his type specimen(s) of Cleothera jocosa were of Mexican origin, therefore the label “Named by Mulsant” on one of these paratype must have been attached in later years because the country listed is Brazil.
