69. Serratitibia barbara Gordon and Canepari , new species

Description. Male holotype. Length 3.0 mm, width 2.3 mm; body elongate, convex. Dorsal surface shiny, lacking alutaceous sculpture. Color yellow; pronotum with black, basomedial macula wide basally, extended anteriorly 2/3 distance to pronotal apex at middle, apex deeply emarginate with yellow; elytron black with 5 large, yellow spots, scutellar spot elongated posteriorly, narrowly connected to discal spot, apical spot transverse ( Fig. 391 ); prosternum, mesoventrite reddish yellow, metaventrite reddish brown medially, nearly black laterally; abdomen yellow. Head punctures small, separated by less than diameter, each puncture as large as 3 eye facets; pronotal punctures larger than head punctures, separated by less than 2 times diameter; elytral punctures equal in size to pronotal punctures, separated by less than 3 times diameter. Clypeus weakly emarginate apically, lateral angle abruptly rounded. Eye canthus about 6 eye facets long, angled forward, apically rounded, yellow. Pronotum narrowed from base to apex, basal angle broadly rounded, anterior angle abruptly rounded, basal margin without bordering line. Epipleuron narrow, grooved, deeply emarginate for reception of femoral apices. Protibial flange less than 1/2 width of remainder of protibia, outer margin arcuate, with about 4 large basal teeth and 8 minute teeth in apical 1/2, sponda extended beyond protibial border. Carinae on prosternal process widely separated at apex, nearly parallel, joined just before prosternal base, connected to base by short stem. Metaventrite without setal tuft. Basal abdominal ventrite with median setal tuft. Abdomen without primary pores laterally between ventrites 4–5; postcoxal line on basal abdominal ventrite arcuate throughout, apex extended forward. Abdominal ventrites with long, sparse, pubescence, punctures on basal 3 ventrites separated by about diameter medially, becoming smaller and dense laterally, ventrites 3–5 densely punctured throughout; 5th ventrite depressed in apical 1/4, apical border weakly emarginate medially, lateral angle of emargination weakly pronounced with faint tubercle bearing tuft of dense setae; 6th ventrite short, narrow, deeply depressed medially, depression glabrous, with median tubercle, apical margin broadly, shallowly emarginate, angle on each side of emargination abruptly rounded, bearing tuft of dense setae. Apical tergite short, narrow, grooved, apex rounded, surface densely, finely punctured. Genitalia with basal lobe nearly as long as paramere, tapered to narrow, obliquely rounded apex; paramere Unm type, wide apically, apex slightly rounded ( Fig. 392, 393 ); sipho slender, curved in basal 1/2, basal capsule with inner arm short, wide, rectangular, outer arm wide, as long as inner arm, with accessory piece, basal border weakly emarginate ( Fig. 394, 395 ).

Female. Unknown.

Variation. Unknown.

Type material. Holotype male; Peru, Dpto. Ayacucho, La Mar, Santa Rosa, 640m, 8-15-IX-1976, Robert Gordon ( USNM).

Remarks. If the elytral color pattern remains consistent, the apically elongate scutellar spot readily identifies this species.
