24. Serratitibia rose Gordon and Canepari , new species

Description. Male holotype. Length 3.0 mm, width 2.4 mm; body oval, convex. Dorsal surface shiny, lacking alutaceous sculpture. Color yellow; pronotum with large, brown, basomedial macula extended 2/ 3 distance to anterior pronotal margin, apex of macula narrowly, weakly incised with yellow; elytron black with 5 large yellow spots arranged in rows of 2 each with apical spot, mediolateral spot irregularly transversely oval, projected inward, apical spot transversely oval, anterior border slightly emarginate ( Fig. 185 ); venter of head, prosternum, meso–, metaventrites dark brown; abdomen yellowish brown. Head punctures small, separated by diameter or less, each puncture as large as 1–2 eye facets; pronotal punctures as large as on head, separated by diameter or less; elytral punctures as large as on pronotum, separated by less than 2 times diameter; metaventral punctures larger than on elytra, separated by diameter or less medially, larger laterally. Clypeus weakly emarginate apically, lateral angle abruptly rounded. Eye canthus about 6 eye facets long, angled forward in basal 2/3, outer 1/3 curved laterally, apically rounded, yellow. Pronotum narrowed from base to apex, basal angle broadly rounded, anterior angle abruptly rounded, lateral margin curved, basal margin with trace of bordering line. Epipleuron narrow, deeply grooved, deeply emarginate for reception of femoral apices. Protibial flange about as wide as remainder of protibia, outer margin slightly arcuate, nearly straight, with about 8 small teeth throughout, sponda extended beyond protibial border. Carinae on prosternal process narrowly separated at apex, weakly convergent, joined at basal 1/4 of prosternum, connected to base by short stem. Metaventrite without setal tuft. Basal abdominal ventrite with median setal tuft. Abdomen with primary pores laterally between ventrites 4–5 small, extended under apical 1/8 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, with median tubercle, apical margin shallowly emarginate, angle on each side of emargination bearing tuft of setae. Apical tergite short, narrow, apex deeply, widely emarginate, surface densely, finely punctured. Genitalia with basal lobe about as long as paramere, sides slightly convergent, apex obliquely truncate; paramere Unm type, wide, ventral margin strongly rounded, dorsal margin straight, apex rounded ( Fig. 186, 187 ); sipho robust, strongly curved in basal 2/3, basal capsule with inner arm long, rectangular, reversely projected toward interior of siphonal arc, outer arm slender, longer than inner arm, with accessory piece, basal border broadly, shallowly emarginate ( Fig. 188, 189 ).

Female. Unknown.

Variation. Unknown.

Type material. Holotype male; ( Brazil), Telemaco Barba (sic), PR, 7/X/86, Peo fau Par (sic) (much of label illegible) ( DZUP).

Remarks. This species is similar to S. shirley in dorsal appearance, primarily because of the inwardly projecting mediolateral spot on each elytron. It is distinguished from S. shirley and all other Serratitibia species by the recurved eye canthus, males with 6th abdominal ventrite tuberculate, apical tergite deeply, broadly emarginate apically, genitalia with ventral margin of paramere strongly rounded, and inner arm of siphonal capsule angled toward inner arc of sipho.
