41. Dilatitibialis edith Canepari and Gordon , new species

Description. Male holotype. Length 3.3 mm, width 2.7 mm; body round, slightly elongate, convex. Dorsal surface smooth, shiny. Color yellow, pronotum with small, slender, sinuate, black basomedian macula in basal 1/3; elytron with scutellum and suture narrowly bordered with black vitta, vitta widened from apex of scutellum to apical 1/8, then narrowed to apex, large, transversely rectangular dark brown macula extended from humeral callus toward suture, macula appears to be made up of partially joined, short vittae, apical declivity with transversely elongate, kidney shaped dark brown macula tenuously reaching sutural vitta ( Fig. 224 ); ventral surface with prosternum, meso- and metaventrite dark brown; abdomen yellow except median 1/3 of ventrites 1-3 yellowish brown. Head punctures small, separated by less than a diameter, each puncture about as large as an eye facet; pronotal punctures slightly larger than head punctures, separated by a diameter or less; elytral punctures slightly larger than those on pronotum, separated by about a diameter; metaventral punctures larger than those on elytron, absent on midline, separated by 1 to 2 times a diameter laterad of midline, coarser and separated by a diameter or less toward lateral margin. Clypeus deeply 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 medially. Epipleuron narrow, grooved, descending externally, deeply emarginate for reception of femoral apices. Protibia widely flanged, flange as wide as remainder of protibia, outer margin gently curved, smooth, sponda slightly extended beyond protibial flange. Carinae on prosternal process narrowly separated at apex, convergent for short distance, then closely parallel, joined at basal 1/6 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 throughout, extended forward, ventrite with sparse, short pubescence and large, dense punctures; ventrites 2-4 pubescent throughout, punctures large, becoming denser toward lateral margin; 5th ventrite coarsely, densely punctured in basal 2/3, apical 1/3 depressed, feebly 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 weakly emarginate, sparsely pubescent on each side of median depression, lateral angle abruptly rounded, surface densely punctured. Apical tergite with apex weakly emarginate. Genitalia with basal lobe slender, about as long as paramere, asymmetrical, sides weakly convergent from base toward apex, apex rounded; paramere wide, curved, Psc, apex with small, ventral projection ( Fig. 225, 226 ); sipho robust, strongly curved in basal 1/2, basal capsule large, inner arm short, slender, tapered to rounded apex, outer arm short, wide, longer than inner arm, with accessory piece, basal border broadly, weakly emarginate ( Fig. 227, 228 ).

Female. Unknown.

Variation. Unknown.

Type material. Holotype male; Peru, Satipo, XI, 1942, Paprzycki. ( USNM).

Remarks. This species is somewhat similar in dorsal appearance to one of the variations of D. semicincta , but male genitalia place it in this group of species. The dorsal color pattern is distinctive and will serve to identify D. edith .
