Description. Male lectotype. Length 3.2 mm, width 3.0 mm; body oval, convex. Dorsal surface shiny. Color black except head yellow, pronotum yellow with black basomedian spot, apex of spot deeply emarginate with yellow; elytron black with 5 yellow spots arranged in rows of 2 plus an apical spot, spot outside of humeral callus semicircular, scutellar spot round, periscutellar, not reaching elytral base or suture, discal spot irregularly round, apical spot kidney shaped ( Fig. 200 ); ventral surface with antenna, mouthparts, pronotal hypomeron, and legs yellow; abdomen black. Head punctures small, separated by less than a diameter, each puncture as large as 1 eye facet; pronotal punctures larger than on head, separated by about a diameter; elytral punctures as large as on pronotum, separated by 4-5 times a diameter; metaventral punctures larger than on elytron, sparse medially, becoming dense laterally. Clypeus emarginate apically, lateral angle abruptly rounded, surface with dense, long pubescence. Eye canthus about 6 eye facets long, angled forward, apically rounded, yellow. Pronotum narrowed from base to apex, sides feebly rounded, basal and anterior angles rounded, basal margin without bordering line. Epipleuron narrow, grooved, deeply emarginate for reception of femoral apices. Protibia flanged, flange arcuate, outer margin smooth. Carinae on prosternal process feebly convergent, extended to pronotal base. Metaventrite without median setal tuft. Abdomen with primary pores laterally between ventrites 4-5 small, extended under apical 1/4 of ventrite 4; postcoxal line on basal abdominal ventrite straight in basal 1/3, extended to apical margin of ventrite at middle, flattened medially, extended forward; ventrites 1-4 with sparse, short pubescence and dense, coarse punctures, 5th ventrite not depressed medially, depressed in apical 1/2, apical margin broadly, deeply emarginate, surface densely, coarsely punctate; 6th ventrite short, narrow, depressed in apical 1/2, apical margin broadly, weakly emarginate, lateral angle of emargination projecting, abruptly rounded, surface densely punctured. Apical tergite densely punctured. Genitalia with basal lobe about as long as paramere, asymmetrical, slender, apex evenly rounded; paramere Psc, wide ( Fig. 201, 202 ); sipho slender, strongly curved in basal 1/2, basal capsule lightly sclerotized, inner arm long, slender, curved, outer arm as long as inner arm, wide, with small accessory piece, basal border broadly emarginate ( Fig. 203, 204 ).

Female: Unknown.

Variation: Unknown.

Type locality. Colombia.

Type depository. MNHL (lectotype here designated).

Geographical distribution. Colombia. Known only from the lectotype.

Remarks. Dilatitibialis jucunda was designated the type of this genus by Duverger (2001). Unfortunately no specimens other than the lectotype have been recognized as D. jucunda . It may be reliably distinguished from those species with similar color patterns only by examination of male genitalia which is very slender before apex; apex slightly rounded; and basal lobe about as long as paramere.

The type specimen is a male in the MNHL labeled “Cayenne, Lacordaire jucunda,” here designated as the lectotype. Mulsant (1850) had specimens from other collections, but he specifically stated that the specimen in the Dejean collection was the type.
