25. Serratitibia janice Gordon and Canepari , new species

Description. Male holotype. Length 2.7 mm, width 2.3 mm; body oval, slightly elongate, convex. Dorsal surface shiny, lacking alutaceous sculpture. Color yellow; pronotum with large, black basomedial macula extended 2/3 distance to anterior pronotal margin, apex of macula narrowly incised with yellow; elytron black with 5 small yellow spots arranged in rows of 2 each with apical spot, mediolateral spot slightly obliquely oval, apical spot transversely oval ( Fig. 190 ); venter of head, median 1/3 of prosternum reddish brown, meso–, metaventrites, abdomen dark brown. Head punctures small, separated by diameter or less, each puncture as large as 2 eye facets; pronotal punctures as large as head punctures, separated by about diameter; elytral punctures larger than on pronotum, separated by 1–2 times diameter; metaventral punctures larger than on elytra, separated by diameter medially, larger laterally. Clypeus weakly emarginate apically, lateral angle abruptly rounded. Eye canthus about 6 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 curved, basal margin without trace of bordering line. Epipleuron narrow, weakly grooved, deeply emarginate for reception of femoral apices. Protibial flange wider than remainder of protibia, outer margin arcuate, with 5–6 large teeth medially ( Fig. 191 ), sponda extended beyond protibial border. Carinae on prosternal process narrowly separated at apex, weakly convergent, joined at basal 1/6 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 large, extended under apical 1/3 of ventrite 4; 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 feebly rounded, surface densely, finely punctured. Genitalia with basal lobe slightly more than 1/2 as long as paramere, sides straight, apex truncate; paramere Unm type, extremely narrow at base, abruptly widened apically, ventral margin widened, dorsal margin weakly emarginate, apex rounded, projected dorsally ( Fig. 192, 193 ); sipho robust, strongly curved in basal 1/2, basal capsule with inner arm short, slender, curved, apex rounded, outer arm longer than inner arm, slender, curved, with accessory piece, basal border broadly, shallowly emarginate ( Fig. 194, 195 ).

Female. Unknown.

Variation. Length 2.6–2.7 mm, width 2.0– 2.3 mm.

Type material. Holotype male; ( Brazil), Itaituba , Amazon ( ZMHB) . Paratypes 2, 1 same data as holotype ( ZMHB) ; 1 ( Brazil), Amazonas (second line illegible( ZMHB).

Remarks. This species seems to have no definitive external characters, but male genitalia with the paramere narrow at base, abruptly widened and projected dorsally toward the apex is unique within Serratitibia .
