61. Dilatitibialis marjorie Canepari and Gordon , new species

Description. Female holotype. Length 3.0 mm, width 2.4 mm; body round, slightly elongate, convex. Dorsal surface with head, pronotum alutaceous, weakly shiny, elytron slightly alutaceous, shiny. Color yellow except head with median brown macula on frons, macula wide at base of eye, narrowed in apical 3/ 4, pronotum with 4 large, dark brown median maculae, 2 wide, somewhat triangular macula in apical 1/ 2, narrowly connected to basal margin at middle, 1 dark brown, triangular spot on each side of middle on basal margin; elytron with 5 brown vittae, sutural vitta narrowly separated from suture except contacting suture at apex, extended from scutellum to apical 1/10, discal vitta in apical 1/2 short, extended from near base to middle of disc, median vitta on apical declivity short, triangular, outer 2 vittae extended from humeral callus to apical 1/6, connected at base, narrowly separated medially, weakly connected in apical 1/2 ( Fig. 324 ); ventral surface with head, prosternum, meso- and metaventrites light brown; abdomen brownish yellow. Head punctures large, separated by less than a diameter, each puncture as large as 3 eye facets; pronotal punctures smaller than head punctures, separated by less than to 3 times a diameter; elytral punctures as large as on pronotum, separated by 1 to 3 times a diameter; metaventral punctures larger than on elytron medially, separated by about a diameter, slightly coarser and separated by a diameter or less toward lateral margin. Clypeus weakly emarginate apically, nearly truncate, 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 straight, basal margin without trace of bordering line. Epipleuron narrow, grooved, weakly descending externally, deeply emarginate for reception of femoral apices. Protibia not flanged, outer margin straight, smooth, sponda slightly extended beyond protibial flange. Carinae on prosternal process widely separated at apex, convergent to basal 1/3 with single carina extended to pronotal base. Abdomen with primary pores laterally between ventrites 4-5 small, extended under apical 1/4 of 4th ventrite; postcoxal line on basal abdominal ventrite weakly flattened along posterior ventrite margin, extended forward, ventrite with short pubescence and large, dense punctures; ventrites 2-4 pubescent throughout, punctures dense, small; 5th ventrite, densely, finely punctured in basal 2/3, apex straight; 6th ventrite with apex arcuate. Genitalia with spermathecal capsule short, slender, cornu widened; bursal cap oval, with 3 arms, median arm faint, apical strut short, apex enlarged ( Fig. 325 ).

Male. Unknown.

Variation. Unknown.

Type material. Holotype male; ( Brazil), Espiritu Santo, Cleothera ceciliae ? Geographica W., ex. Coll. J. Weise. ( ZMHB).

Remarks. This female specimen has a dorsal color pattern composed of brown vittae on a yellow background, as do certain other species, but the only closely similar Dilatitibialis species is D. hybridula which has a different arrangement of dorsal vittae.
