80. Serratitibia denise Gordon and Canepari , new species

Description. Male holotype. Length 2.7 mm, width 2.2 mm; body oval, slightly elongate, convex. Dorsal surface shiny, lacking alutaceous sculpture. Color yellow; pronotum with black, mediobasal macula extended 2/3 distance to apical pronotal margin, apex of macula broadly, triangularly emarginate with yellow; elytron black with 5 small, pale spots, spots arranged in transverse rows of two each plus one at apex, scutellar and discal spots reddish yellow, remaining spots yellow, mediolateral spot transversely rectangular, projected inward, apical spot transversely oval ( Fig. 448 ); prosternum brownish yellow, meso–, metaventrites dark reddish brown; abdomen yellowish brown. Head punctures small, separated by less than diameter, each puncture as large as 1 eye facet; pronotal punctures as large as on head, separated by diameter or less; elytral punctures as large as pronotal punctures, separated by diameter or less. 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 slightly rounded, anterior angle abruptly rounded, lateral margin weakly rounded, basal margin without bordering line. Epipleuron narrow, grooved, deeply emarginate for reception of femoral apices. Protibial flange as wide as remainder of protibia, outer margin arcuate with about 8 small teeth throughout, teeth large medially, sponda extended beyond protibial border. Carinae on prosternal process widely separated at apex, convergent, joined at basal 1/6 of prosternum, connected to base by short stem. Metaventrite without setal tuft. Basal abdominal ventrite with median setal tuft. Abdomen without primary pores laterally between ventrites 4–5; postcoxal line on basal abdominal ventrite straight in basal 1/3, flattened along apical margin of ventrite, apex extended forward. Abdominal ventrites with short, sparse pubescence, punctures on basal 3 ventrites coarse, 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 margin weakly emarginate, with small tubercle bearing tuft of setae on each side of median depression; 6th ventrite short, narrow, weakly depressed in apical 1/2, depression glabrous, without median tubercle, apical margin shallowly emarginate, angle on each side of emargination rounded, bearing small tuft of dense setae. Apical tergite short, narrow, apex emarginate medially, surface densely, finely punctured. Genitalia with basal lobe about as long as paramere, wide, sides convergent, apex obliquely rounded; paramere Unm type, slender, slightly widened apically, dorsal margin straight, ventral margin rounded, apex oblique ( Fig. 449, 450 ); sipho curved in basal 2/3, basal capsule with inner arm short, wide, apex obliquely truncate, outer arm 2 times as long as inner arm, wide, with accessory piece, basal border broadly, shallowly emarginate ( Fig. 451, 452 ).

Female. Unknown.

Variation. Unknown.

Type material. Holotype male; Peru, Loreto, Picuruyacu, 150 m., 9/ 13-VIII-2008, Leg. R. Westerduijn, Altered forest ( MKRB).

Remarks. The male genitalia have a distinctively shaped paramere distinguishing this species from all other Serratitibia . In addition, the reddish yellow scutellar and discal spots are diagnostic, most other species have all elytral spots uniform in color, usually entirely yellow.
