5. Serratitibia michelle Gordon and Canepari , new species

Description. Male holotype. Length 2.6 mm, width 2.0 mm; body oval, convex. Dorsal surface shiny, lacking alutaceous sculpture. Color yellow; pronotum with short, narrow, median macula, anterior margin of macula triangularly indented with yellow medially, extended anteriorly 1/5 distance to pronotal apex; elytron brown with large, yellow humeral, scutellar, discal, and apical spots broadly connected, forming irregular vitta, mediolateral and apical spot narrowly joined ( Fig. 81 ); meso–, metaventrites dark reddish brown; abdomen yellowish brown. Head punctures small, separated by less than diameter, each puncture as large as 1–2 eye facets; pronotal punctures equal in size to head punctures, separated by diameter or less; elytral punctures as large as on pronotum, separated by 1–2 times diameter; metaventral punctures larger than on elytra, separated by diameter or less medially, larger and separated by less than diameter laterally. Clypeus weakly emarginate apically, lateral angle abruptly rounded. Eye canthus about 6 eye facets long, angled forward, apically rounded, yellow. Pronotum narrowed from base to apex, basal angle broadly rounded, anterior angle abruptly rounded, lateral margin rounded, basal margin with faint trace of bordering line. Epipleuron narrow, weakly grooved, deeply emarginate for reception of femoral apices. Protibial flange narrower than remainder of protibia, outer margin arcuate, with about 8 small, distinct teeth, sponda extended beyond protibial border. Carinae on prosternal process narrowly separated at apex, convergent, joined at basal 1/3 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, flat along margin, apex extended forward. Abdominal ventrites 1–4 with short, sparse pubescence, punctures on basal 3 ventrites large, separated by about 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; 6 th ventrite narrow, deeply depressed medially, depression glabrous, without median tubercle, apical border shallowly emarginate, angle on each side of emargination broadly rounded, bearing tuft of setae. Apical tergite short, narrow, apex feebly rounded, surface densely, finely punctured. Genitalia with basal lobe nearly as long as paramere, sides weakly convergent, apex obliquely rounded; paramere Unm type, widened apically, apex rounded ( Fig. 82, 83 ); sipho robust, curved in basal 1/2, basal capsule with inner arm short, wide, apex truncate, outer arm wider and longer than inner arm, with accessory piece, basal border deeply emarginate ( Fig. 84, 85 ).

Female. Unknown.

Variation. Unknown.

Type material. Holotype male; Brazil, Nhambiquara, M. Grosso, XI-1966, M. Alvarenga leg. ( DZUP).

Remarks. The elytral color pattern is obviously derived from fusing of 5 elytral spots. If this is constant, then S. michelle is easily identified. If it is not constant and other specimens prove to have 5 discrete spots, then identification will depend entirely on comparison of male genitalia.
