9. Serratitibia kimberly Gordon and Canepari , new species

Description. Male holotype. Length 3.0 mm, width 2.5 mm; body oval, convex. Dorsal surface shiny, lacking alutaceous sculpture. Color yellow; pronotum with large, mediobasal, black macula extended slightly more than 1/2 distance to anterior pronotal margin, anterior border of macula indented with yellow; elytron black with 5 large, yellow spots in rows of 2 each with single apical spot, mediolateral spot round, apical spot transversely rectangular ( Fig. 102 ); venter of head, prosternum, meso–, metaventrites black; abdomen dark brown. 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 less than 2 times diameter; elytral punctures as large as on pronotum, separated by less than 3 times diameter; metaventral punctures larger than on elytra, separated by less than diameter medially, slightly larger laterally. Clypeus weakly emarginate apically, lateral angle abruptly rounded. Eye canthus about 5 eye facets long, 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 narrower than remainder of protibia, outer margin weakly arcuate, with about 4 prominent teeth medially, sponda extended beyond protibial border. Carinae on prosternal process narrowly separated at apex, convergent, joined at basal 1/8 of prosternum, connected to base by short stem. Metaventrite without setal tuft. Basal abdominal ventrite with tuft of setae on each side of middle. Abdomen with primary pores laterally between ventrites 4–5 large, extended under apical 1/3 of ventrite 4; postcoxal line on basal abdominal ventrite angled to posterior ventrite margin, rounded along margin, apex extended forward. Abdominal ventrites 1–4 with short, sparse pubescence, punctures on basal 3 ventrites large, separated by less than diameter medially, 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 pronounced 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 abruptly pronounced, bearing tuft of setae. Apical tergite short, narrow, apex barely perceptibly emarginate medially, surface densely, finely punctured. Genitalia with basal lobe 3/4 length of paramere, sides weakly convergent, apex nearly truncate; paramere Unm type, wide, apex rounded ( Fig. 103, 104 ); sipho robust, curved in basal 1/2, basal capsule with inner arm long, wide, apex widened, medially emarginate, outer arm slightly longer than inner arm, slightly widened at apex, with accessory piece, basal border broadly, deeply emarginate ( Fig. 105, 106 ).

Female. Similar to male except pronotum with mediobasal macula extended almost to anterior pronotal margin, slightly indented with yellow medially; elytron with trace of humeral spot. Genitalia with spermathecal capsule long, slender, curved medially, cornu slightly widened; bursal cap with 3 arms, outer arms distinct, inner arm weakly evident, cap narrowly oval, apical strut elongate, slender, weakly spatulate at apex ( Fig. 107 ).

Variation. Length 2.5–3.0 mm, width 2.0– 2.5 mm. Abdominal color varies from the typical described above to entirely yellow.

Type material. Holotype male; Peru, Dept. of Cuzco, Paucartambo, Kosnipata Bosque Nublado Reserve, Coll. MVL Barclay , Cock-of-the-Rock Lodge , Montane Wet Forest , 1400m, iv/1999, 18 o 03’21"S 71 o 31’44"W ( BMNH) . Paratypes, 3, same data as holotype ( BMNH).

Remarks. Although possessing the common yellow on black dorsal color pattern, this species may be distinguished by a combination of rounded parameral apex, lack of median tubercle on 6th abdominal ventrite, large primary pores between ventrites 4–5, and Peruvian type locality.
