11. Dilatitibialis poortmani (Mulsant) , new combination

Cleothera poortmanni Mulsant, 1850: 572 .

Hyperaspis poortmanni: Crotch 1874: 218 ; Korschefsky 1931: 194; Blackwelder 1945: 448.

Description. Male. Length 3.0 mm, width 2.6 mm; body rounded, slightly elongate, convex. Dorsal surface shiny, lacking alutaceous sculpture. Color yellow except pronotum with large, dark brown, basomedian macula deeply emarginate with yellow medially, anterolateral angle weakly emarginate, small, elongate brown spot on each side adjacent to median macula; elytron bordered with brown on sutural, lateral and apical margins, sutural border wide in median 5/6, lateral border narrow, apical border wide, surface with 4 large, brown spots, 2 in anterior 1/2, 2 on apical declivity, humeral spot irregularly rectangular, anterior sutural spot elongate oval, outer border emarginate, posterolateral spot irregularly rectangular, posteromedian spot broadly triangular ( Fig. 56 ); ventral surface with prosternum, meso- and metaventrites dark brown; abdomen dark brown medially, lateral margins and ventrites 5-6 brownish yellow. Head punctures small, separated by about a diameter, each puncture as large as 1-2 eye facets; 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 large, dense, separated by a diameter or less medially, separated by less than a diameter toward lateral margin. Clypeus emarginate apically, lateral angle rounded, surface with sparse, long pubescence. Eye canthus about 6 eye facets long, angled forward, apically rounded, yellow. Pronotum narrowed from base to apex, basal and anterior angles abrupt, lateral margin slightly rounded, basal margin without trace of bordering line. Epipleuron narrow, grooved, descending externally, deeply emarginate for reception of femoral apices. Protibia strongly flanged, flange wider than remainder of protibia, outer margin rounded, smooth, sponda distinctly extended beyond protibial flange. Carinae on prosternal process narrowly separated at apex, convergent toward base, joined at basal 1/3 with single carina extended to basal margin of prosternum. Metaventrite without setal tuft. Basal abdominal ventrite with long, sparse setae medially. Abdomen with primary pores laterally between ventrites 4-5 large, extended under apical 1/2 of 4th ventrite; postcoxal line on basal abdominal ventrite rounded, slightly flattened along posterior ventrite margin, ventrite with sparse, long pubescence and large, dense punctures medially; ventrites 2-4 pubescent throughout, punctures small, dense, becoming denser toward lateral margin; 5th ventrite coarsely, densely punctured in basal 2/3, depressed by primary pore laterally, without 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 feebly punctured. Apical tergite finely, densely punctured, pubescent, apex weakly rounded. Genitalia with basal lobe about as long as paramere, asymmetrical, straight, narrowed at apical 2/3, apex slightly rounded, nearly truncate; paramere broadly, weakly Psc, apex with small ventral projection, dorsal margin broadly rounded ( Fig. 57, 58 ); sipho robust, strongly curved in basal 1/2, basal capsule large, inner arm slender, slightly sinuate, narrowly rounded, outer arm wider and slightly longer than inner arm, with accessory piece, basal border broadly, deeply emarginate ( Fig. 59, 60 ).

Female. Head with vertex brown, brown area extended anteriorly onto frons at base of eye. Genitalia with spermathecal capsule short, wide, widened from base to apex, anterior 1/4 of cornu extended into a slender, round “beak”; bursal cap broadly oval, with 2 outer sclerotized arms, apical strut long, slender, apex flattened in lateral view ( Fig. 61 ).

Variation. Length 2.6 to 3.4 mm, width 2.3 to 2.6 mm. Dorsal spots vary from brown to nearly black, pronotal maculae vary from the pattern described above to completely fused with only the lateral and anterolateral angle yellow, elytron with anterior inner and outer spots often incompletely fused medially.

Type locality. Brazil.

Type depository. MNHL (lectotype here designated).

Geographical distribution. Brazil.

Specimens examined. 25. Brazil. Distributed over much of eastern Brazil. ( BMNH) ( CMNH) ( DZUP) ( MNHL) ( USNM) ( ZMHB).

Remarks. Dilatitibialis poortmanni is a frequently collected species defined by the dorsal spot pattern. Sicard (1912) described Cleothera poortmanni var. bistrimaculata , type not found, that is almost certainly a description of the form having anterior elytral spots incompletely fused.

A specimen in the Dejean collection, MNHL, labeled “Brasilia” is here designated the lectotype of D. poortmanni . A female in the BMNH labeled “ Syntype (blue bordered disc)/5771 (blue disc)/Poortmanni Muls. Bresil (handwritten, green paper)/Named by Mulsant.” is designated a paralectotype.
