50. Dilatitibialis josephine Canepari and Gordon , new species

Description. Male holotype. Length 2.8 mm, width 2.3 mm; body round, slightly elongate, convex. Dorsal surface smooth, shiny. Color black except pronotum yellow with large, black, basomedian macula deeply, broadly emarginate with yellow at apex and anterolateral angle; elytron with 5 large, yellow spots arranged in rows of 2 each plus apical spot, humeral spot rectangular, posterior spot shortly rectangular with anterior border emarginate, all other spots more or less round ( Fig. 274 ); ventral surface with antenna, mouthparts, prothoracic hypomeron, legs yellow; abdomen with ventrites 1-4 dark brown medially and yellowish brown in lateral 1/4, ventrites 5-6 brownish yellow. Head punctures small, separated by a diameter or less, each puncture as large as an eye facet; pronotal punctures larger than head punctures, separated by 1 to 2 times a diameter; elytral punctures smaller than on pronotum, separated by less than to 3 times a diameter; metaventral punctures larger than on elytron medially, dense, separated by less than a diameter medially, slightly coarser and separated by less than a diameter toward lateral margin. Clypeus weakly 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 straight, basal margin without trace of bordering line. Epipleuron narrow, grooved, weakly descending externally, deeply emarginate for reception of femoral apices. Protibia narrowly flanged, flange slightly narrower than remain- der of protibia, outer margin weakly curved, smooth, sponda slightly extended beyond protibial flange. Carinae on prosternal process narrowly separated at apex, convergent to basal 1/3 with single carina extended to pronotal base. Metaventrite without setal tuft. Basal abdominal ventrite without setal tuft. Abdomen with primary pores laterally between ventrites 4-5 large, extended under apical 1/2 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, 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 border 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, as long as paramere, asymmetrical, sides slightly convergent from base to anterior 2/3, anterior 1/3 widened, strongly bent upward to apex, apex weakly rounded; paramere wide, almost straight, Psc, apex with small, ventral projection ( Fig. 275, 276 ); sipho robust, strongly curved in basal 1/2, basal capsule large, inner arm long, slender, weakly curved, apex abruptly rounded, outer arm longer and wider than inner arm, with accessory piece, basal border deeply emarginate ( Fig. 277, 278 ).

Female. Unknown.

Variation. Unknown.

Type material. Holotype male; Bolivia, La Paz N. Yungas, Cruze Loma, IV-4-78, C. R. Ward. ( USNM).

Remarks. Dilatitibialis josephine is similar to several other species with 5 yellow elytral spots on a dark background, and difficult to distinguish from them except by examination of male genitalia, which are similar to those of D. jucunda and D. fallax . The pronotum has a basal macula deeply emarginate with yellow at apex and anterolateral angle, the metaventrite is densely, coarsely punctured medially, and it has a Bolivian distribution. These characters will aid in identification, but male genitalia must be examined to accurately distinguish this species.
