Dilatitibialis tropicalis (Mulsant) , new combination . Cleothera tropicalis Mulsant, 1850: 1038 . Hyperaspis tropicalis : Korschefsky 1931: 198 ; Blackwelder 1945: 448 . Description . Male holotype . Length 3.1 mm , width 2.3 mm ; body rounded, convex. Color yellow; pronotum with large, basomedian, dark brown macula, macula wide across base, narrowed anteriorly; elytron dark brown with 5 yellow spots arranged as in Fig. 97 ; ventral surface with head, prosternum, meso- and metaventrites dark reddish yellow; abdomen dark yellowish brown medially, yellow laterally. Head punctures separated by about a diameter, each puncture 2 or 3 times larger than eye facet; pronotal punctures same size as head punctures, separated by a diameter or less, elytral punctures larger than on pronotum, separated by 1-3 times a diameter; metaventral punctures 3 or 4 times as large as on pronotum, separated by a diameter or more medially, becoming larger and contiguous toward lateral margin. Clypeus feebly emarginate apically, lateral angle rounded, clypeus and frons with sparse, long pubescence. Eye canthus elongate, about 8 eye facets long, slightly angled forward, apically acute, reddish yellow. Pronotum narrowed from base to apex, basal angle abruptly rounded, anterior angle evenly rounded, basal margin without bordering line. Epipleuron narrow, grooved, deeply emarginate for reception of femoral apices. Protibia not flanged, outer margin narrowly oblique, smooth. Carinae on prosternal process wide at apex, convergent toward base, acutely joined at base with single carina extended to basal margin of prosternum. Metaventrite without setal tuft. Abdomen with primary pores laterally between ventrites 4- 5 large, deeply indenting apical margin of 4th ventrite; postcoxal line on basal abdominal ventrite rounded, extended to apical margin of ventrite at middle, then broadly forward, ventrite with sparse, long pubescence and dense, sparse punctures medially; ventrites 2-4 sparsely pubescent throughout, punctures small, dense, becoming denser toward lateral margin; 5th ventrite slightly depressed medially, apical margin deeply emarginate, surface densely punctate in basal 1/2, apical 1/2 impunctate; 6th ventrite depressed in apical 1/2, apical margin deeply emarginate, angle on each side of median depression pronounced, abruptly rounded, surface impunctate. Apical tergite finely, indistinctly punctured. Genitalia with basal lobe slightly shorter than paramere, asymmetrical, wide, narrowed and bent in apical 1/6; paramere Psc , slender, strongly curved ( Fig. 98, 99 ); sipho robust, strongly curved in basal 2/3, basal capsule large, inner arm short, wide, dorsally truncate, outer arm wide, slightly longer than inner arm, with small accessory piece, basal border deeply emarginate ( Fig. 100, 101 ). Female . Unknown. Variation . Unknown. Type locality . Brazil . Type depository . ZMUC ( holotype , examined). Geographical distribution . Known only from the Brazilian. Specimens examined . The holotype . Remarks . The dorsal color pattern is similar to that of several other species of Dilatitibialis , but male genitalia are distinctive. Mulsant (1850) had only one example of this species, the holotype male labeled “ Brasil . Tropicalis Muls. (handwritten)/ HOLOTYPE Cleothera tropicalis Mulsant (red paper).”
