83. Serratitibia frances Gordon and Canepari , new species

Description. Male holotype. Length 2.6 mm, width 2.1 mm; body oval, convex. Dorsal surface shiny, lacking alutaceous sculpture. Color yellow; head with vertex and clypeus black; pronotum with short, narrow, black basomedial macula extended 1/4 distance to anterior pronotal margin, apex of macula deeply, broadly indented with yellow; elytron black with 5 yellow spots arranged in rows of 2 each, mediolateral spot irregularly rectangular, apical spot transversely rectangular ( Fig. 465 ); venter of head, prosternum, meso–, metaventrites black; abdomen brown. Head punctures small, separated by diameter or less, each puncture as large as 1 eye facet; pronotal punctures as large as head punctures, separated by diameter or less; elytral punctures as large as on pronotum, separated by less than 2 times diameter; metaventral punctures larger than on elytra, separated by less than diameter medially, larger laterally. Clypeus truncate apically, lateral angle abruptly rounded. Eye canthus about 5 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 rounded, basal margin without trace of bordering line. Epipleuron narrow, deeply grooved, deeply emarginate for reception of femoral apices. Protibial flange as wide as remainder of protibia, outer margin nearly straight, with about 10 small, indistinct teeth throughout, sponda extended beyond protibial border. Carinae on prosternal process narrowly separated at apex, slightly convergent, joined at basal 1/4 of prosternum, connected to base by short stem. Metaventrite with setal tuft. Basal abdominal ventrite with median setal tuft. Abdomen without primary pores; 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 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 truncate, surface densely, finely punctured. Genitalia with basal lobe wide, about as long as paramere, sides slightly convergent, apex truncate, slightly oblique; paramere Unm type, wide, widened apically, apex rounded ( Fig. 466 ); sipho robust, strongly curved in basal 3/4, basal capsule with inner arm short, wide, apex obliquely truncate with outer angle projecting, outer arm 3 times longer than inner arm, wide, with accessory piece, basal border broadly, shallowly emarginate ( Fig. 467, 468 ).

Female. Unknown.

Variation. Unknown.

Type material. Holotype male; Bolivia, Prov. La Paz, Cumbre Alto Beni, 7-15.iv.2004, vicinity of Caravani , 1685 m, 15 o 40’19"S, 67 o 29’35"W, malaise traps, leg. S.D. Gaimari and M. Hauser ( CSCA).

Remarks. Among many similar appearing species, S. frances is distinct by a combination of yellow head with black vertex and clypeus, mostly yellow pronotum, metaventrite and basal abdominal ventrite each with a setal tuft (see comments under S. christine ).
