22. Dilatitibialis crystal Canepari and Gordon , new species

Description. Male holotype. Length 2.4 mm, width 1.7 mm; body rounded, convex. Dorsal surface shiny with head and pronotum weakly alutaceous Color yellow; pronotum with small, narrow, light brown basomedian macula, macula triangularly extended anteriorly at each end, 1 small, pale brown, triangular median spot on each side of middle at center of pronotum; elytron with 4 irregular, light brown spots in rows of 2 each, humeral spot indistinctly connected to discal spot and to lateral margin, posterolateral spot reaching lateral margin ( Fig. 118 ); ventral surface with head, prosternum, meso- and metaventrites light brown; abdomen brownish yellow medially, yellow in lateral 1/4. Head punctures separated by about a diameter, each puncture about as larger as an eye facet; pronotal punctures larger than head punctures, separated by less than to twice a diameter, elytral punctures larger than on pronotum, separated by less than to 3 times a diameter; metaventral punctures larger than on elytron, separated by a diameter or more medially, becoming larger and separated by less than a diameter toward lateral margin. Clypeus feebly emarginate apically, lateral angle rounded, clypeus with sparse, long pubescence. Eye canthus elongate, about 5 eye facets long, angled forward, apically rounded, yellow. Pronotum narrowed from base to apex, basal angle abruptly rounded, anterior angle evenly rounded, lateral margin slightly curved, basal margin without bordering line. Epipleuron narrow, grooved, not descending externally, deeply emarginate for reception of femoral apices. Protibia widely flanged, outer margin arcuate, smooth. Carinae on prosternal process wide at apex, convergent toward base, acutely joined at basal 1/4 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 large, extended under apical 1/3 of 4th ventrite; postcoxal line on basal abdominal ventrite rounded, flattened along posterior margin of ventrite, then broadly forward, ventrite with sparse, long pubescence and dense punctures medially; ventrites 2-4 sparsely pubescent throughout, punctures large, dense, becoming denser toward lateral margin; 5th ventrite depressed in apical 1/3, apical margin broadly emarginate, surface densely punctate in basal 1/2, apical 1/2 nearly impunctate; 6th ventrite depressed medially, apical margin shallowly emarginate, angle on each side of median depression pronounced, abruptly rounded, surface impunctate. Apical tergite densely punctured, apex rounded. Genitalia with basal lobe slightly shorter than paramere, asymmetrical, wide, apex irregularly triangular; paramere weakly Psc, slender, weakly curved, apically rounded ( Fig. 119, 120 ); sipho robust, strongly curved in basal 1/2, basal capsule large, inner arm long, slender, apically rounded, outer arm wider and slightly longer than inner arm, with accessory piece, basal border deeply emarginate ( Fig. 121, 122 ).

Female. Unknown.

Variation. Unknown.

Type material. Holotype male; Colombia, Cnd. (Cundinamarca), Anapoima , 14 Aug 1965, J.A. Ramos Collector. ( USNM).

Remarks. The dorsal color pattern of this species is distinctive within Dilatitibialis . Male genitalia with a triangular basal lobe apex are similar to those of D. florifera , but the parameres differ in that those of D. florifera are strongly Psc, while parameres of D. crystal are much less so.
