84. Serratitibia jean Gordon and Canepari , new species

Description. Male holotype. Length 2.3 mm, width 1.8 mm; body oval, convex. Dorsal surface shiny, lacking alutaceous sculpture. Color yellow; pronotum with small, brown basomedial macula extended about 1/4 distance to anterior pronotal margin, apex of macula broadly emarginate with yellow; elytron black with 5 small, yellow spots arranged in rows of 2 each with apical spot, mediolateral spot irregularly round, apical spot transversely oval ( Fig. 469 ); venter of head, prosternum, meso–, metaventrites dark brown; abdomen yellow except median area of ventrites 1–4 brownish yellow. 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 1–3 times diameter; metaventral punctures larger than on elytra, separated by about 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 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 abruptly arcuate, with 3 large teeth at median apex of flange, several small teeth on both sides of middle, 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 without primary pores; postcoxal line on basal abdomi- nal 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 3/4 as long as paramere, sides weakly convergent, apex obliquely truncate; paramere Unm type, wide, widened toward truncate apex, apex slightly emarginate ( Fig. 470, 471 ); sipho robust, strongly curved in basal 2/3, basal capsule with inner arm long, wide, apex truncate, outer arm about as long as inner arm, wide, with accessory piece, basal border broadly, shallowly emarginate ( Fig. 472, 473 ).

Female. Unknown.

Variation. Unknown.

Type material. Holotype male; Brazil, Para, Acc.No. 2966, June ( CMNH).

Remarks. Small size, male pronotum mostly yellow, eye canthus short, and paramere of male genitalia abruptly truncate apically with truncation slightly emarginate distinguish this species.
