41. Serratitibia quincemil Gordon and Canepari , new species

Description. Male holotype. Length 2.0 mm, width 1.5 mm; body oval, convex. Dorsal surface shiny, lacking alutaceous sculpture. Color yellow; pronotum with large, black basomedial macula extended about 2/3 distance to anterior pronotal margin, apex of macula narrowly emarginate with yellow; elytron black with 5 small, yellow spots arranged in rows of 2 each with apical spot, mediolateral spot oval, apical spot transversely oval ( Fig. 275 ); median 1/3 of prosternum, meso–, metaventrites reddish brown; abdomen reddish yellow except median area of ventrites 1–3 dark brown. Head punctures small, separated by 1–2 times diameter, each puncture as large as 1 eye facet; pronotal punctures as large as head punctures, separated by 1–2 times diameter; elytral punctures as large as on pronotum, separated by 1– 3 times diameter; metaventral punctures larger than on elytra, separated by less than 2 times diameter medially, larger laterally. Clypeus weakly emarginate apically, lateral angle abruptly rounded. Eye canthus about 4 eye facets long, slightly angled forward, apically rounded, yellow. Pronotum narrowed from base to apex, basal angle broadly rounded, anterior angle abruptly rounded, lateral margin straight, basal margin with trace of bordering line. Epipleuron narrow, deeply grooved, deeply emarginate for reception of femoral apices. Protibial flange wider than remainder of protibia, outer margin weakly arcuate, with about 8 small teeth throughout, median 2 teeth slightly larger, sponda extended beyond protibial border. Carinae on prosternal process narrowly separated at apex, weakly convergent, joined at basal 1/4 of prosternum, connected to base by short stem. Metaventrite with setal tuft ( Fig. 280 ). Basal abdominal ventrite with median setal tuft. Abdomen with primary pores laterally between ventrites 4–5 small, extended under apical 1/8 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 medially emarginate, surface densely, finely punctured. Genitalia with basal lobe slender, 5/6 as long as paramere, sides weakly convergent, apex obliquely truncate; paramere Unm type, slender, slightly widened apically, apex truncate ( Fig. 276, 277 ); sipho robust, strongly curved in basal 2/3, basal capsule with inner arm short, wide, tapered to apex, apex irregularly truncate, outer arm slightly longer than inner arm, wide, with accessory piece, basal border broadly, shallowly emarginate ( Fig. 278, 279 ).

Female. Unknown.

Variation. None observed.

Type material. Holotype male; Peru, Dpt. Cuzco, Prov. Quispicanchis, Quincemil, 6-11-X-1976, Robert Gordon ( USNM) . Paratypes; 2, same data as holotype ( USNM) .

Remarks. This little species is distinguished by the small size; widely spaced head punctures, small abdominal primary pores, and lack of a median tubercle on the male 6th abdominal ventrite.
