46. Serratitibia linda Gordon and Canepari , new species

Description. Male holotype. Length 3.0 mm, width 2.5 mm; body slightly elongate, convex. Dorsal surface shiny, lacking alutaceous sculpture. Color yellow; pronotum with black, basomedial macula wide basally, extended anteriorly 2/3 distance to pronotal apex at middle, apex of macula weakly, widely emarginate with yellow; elytron black with 5 small, yellow spots arranged in transverse rows of two each plus one at apex, apical spot transverse, anterior margin slightly emarginate, spots not crisply defined, edges of spots blended slightly with surrounding black area ( Fig. 301 ); prosternum, epipleuron, meso–, metaventrites black; abdomen yellowish brown. Head punctures small, separated by less than diameter, each puncture as large as 3 eye facets; pronotal punctures larger than head punctures, separated by less than 2 times diameter; elytral punctures equal in size to pronotal punctures, separated by less than 3 times diameter. Clypeus weakly emarginate apically, nearly truncate, 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, basal margin without bordering line. Epipleuron narrow, slightly grooved, deeply emarginate for reception of femoral apices. Protibial flange about as wide as remainder of protibia, outer margin arcuate, with about 12 small teeth ( Fig. 302 ), sponda extended beyond protibial border. Carinae on prosternal process widely separated at apex, nearly parallel, joined just before prosternal base. Metaventrite without setal tuft. Basal abdominal ventrite with median setal tuft. Abdomen with primary pores laterally between ventrites 4–5 small, extended under apical 1/6 of ventrite 4; postcoxal line on basal abdominal ventrite arcuate throughout, apex curved forward. Abdominal ventrites with long, sparse, pubescence, punctures on basal 2 ventrites separated by about diameter medially, becoming smaller and dense laterally, ventrites 3–5 densely punctured throughout; 5th ventrite depressed medially in apical 3/4, apical margin deeply emarginate medially, lateral angle of emargination pronounced with small tubercle bearing tuft of dense setae; 6th ventrite short, narrow, deeply depressed medially, depression glabrous, with median tubercle, densely punctured, apical margin shallowly emarginate with tuberculate angle on each side, angle with tuft of dense setae. Apical tergite short, narrow, apex rounded, surface densely, finely punctured. Genitalia with basal lobe shorter than paramere, wide, weakly tapered to obliquely truncate apex; paramere Unm type, widened apically, apex obliquely truncate ( Fig. 303, 304 ); sipho slender, curved in basal 1/2, basal capsule with inner arm short, wide, rectangular, outer arm short, wide, slightly longer than inner arm, with accessory piece, basal border weakly emarginate ( Fig. 305, 306 ).

Female. Unknown.

Variation. Unknown.

Type material. Holotype male; 8854, Fry Rio Jan. ( Brazil), Fry Coll. 1905. 100., Cleothera gacognii Mul. ( BMNH).

Remarks. Somewhat similar to S. gloria because of the large size and tendency of the elytral spots to have slightly blurred edges, but distinguished by a median tubercle on the 6th abdominal sternum, and male pronotum with large, basomedial macula extended 2/3 distance to anterior pronotal margin, basomedial macula with apical border broadly, shallowly emarginate.
