32. Serratitibia debra Gordon and Canepari , new species

Description. Male holotype. Length 2.4 mm, width 1.7mm; body oval, convex. Dorsal surface shiny, lacking alutaceous sculpture. Color yellow; pronotum with small, black basomedial macula extended 1/2 distance to anterior pronotal margin, apex of macula emarginate with yellow; elytron black with 5 yellow spots arranged in rows of 2 each plus apical spot, mediolateral spot round, apical spot transversely oval, apical margin rounded ( Fig. 226 ); meso–, metaventrites reddish brown; abdomen yellow. Head punctures small, separated by less than diameter, each puncture as large as 1 eye facet; pronotal punctures equal in size to head punctures, separated by diameter or less; elytral punctures larger than on pronotum, separated by less than 3 times diameter; metaventral punctures larger than on elytra, separated by less than diameter medially, larger laterally. Clypeus weakly emarginate apically, lateral angle abruptly rounded. Eye canthus about 5 eye facets long, slightly angled forward, apically rounded, yellow. Pronotum nar- rowed from base to apex, basal angle broadly rounded, anterior angle abruptly rounded, lateral margin straight, basal margin without trace of bordering line. Epipleuron narrow, shallowly grooved, deeply emarginate for reception of femoral apices. Protibial flange as wide as remainder of protibia, outer margin sinuate, with about 8 small teeth throughout, sponda extended beyond protibial border. Carinae on prosternal process narrowly separated at apex, parallel, joined at basal 1/4 of prosternum, connected to base by short stem. Metaventrite without setal tuft. Basal abdominal ventrite 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 angled to posterior ventrite margin, flattened along margin, apex extended forward. Abdominal ventrites 1–4 with short, sparse pubescence, punctures on basal 3 ventrites large medially, separated by diameter or less, becoming smaller and dense laterally, ventrites 3– 5 densely punctured throughout; 5th ventrite depressed medially in apical 1/2, apical border weakly emarginate medially, lateral angle of emargination with small tubercle bearing tuft of dense setae; 6th ventrite narrow, deeply depressed medially, depression glabrous, without median tubercle, apical margin shallowly emarginate, angle on each side of emargination bearing tuft of setae. Apical tergite short, narrow, apex weakly emarginate, surface densely, finely punctured. Genitalia with basal lobe 5/6 length of paramere, sides convergent, apex obliquely rounded; paramere Unm type, wide, slightly widened apically, apex truncate ( Fig. 227, 228 ); sipho robust, curved in basal 2/3, basal capsule with inner arm short, wide, tapered to truncate apex, outer arm slightly longer than inner arm, wide, with accessory piece, basal border broadly, shallowly emarginate ( Fig. 229, 230 ).

Female. Unknown.

Variation. Unknown.

Type material. Holotype male; Bolivia, Yungas de la Paz, Heyne V. ( ZMHB).

Other specimen. 1. ( Bolivia) “O. Bolivien,” Prov. Sara, J. Steinbach S. V. ( ZMHB).

Remarks. Small size, small basomedial pronotal macula apically indented with yellow, paramere only slightly widened apically, and 6th abdominal ventrite lacking a median tubercle distinguish S. debra from other Bolivian species in this group.
