29. Serratitibia stephanie Gordon and Canepari , new species

Description. Male holotype. Length 3.0 mm, width 2.5 mm; body oval, convex. Dorsal surface shiny, lacking alutaceous sculpture. Color yellow; pronotum with small, black basomedial macula extended slightly more than 1/2 distance to anterior pronotal margin, apex of macula broadly, deeply emarginate with yellow; elytron black with 5 large yellow spots arranged in rows of 2 each plus apical spot, mediolateral spot obliquely, irregularly oval, apical spot transversely rectangular and apical margin faintly, broadly emarginate ( Fig. 211 ); venter of head, prosternum reddish brown, meso–, metaventrites black; abdomen yellowish brown. Head punctures small, separated by less than diameter, each puncture as large as 1 eye facet; pronotal punctures equal in size to head punctures, separated by diameter or less; elytral punctures larger than on pronotum, separated by less than 3 times diameter; metaventral punctures larger than on elytra, separated by diameter or less medially, larger laterally. Clypeus distinctly 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 rounded, basal margin without trace of bordering line. Epipleuron narrow, weakly grooved, deeply emarginate for reception of femoral apices. Protibial flange as wide as remainder of protibia, outer margin arcuate, with about 12 small teeth throughout, median tooth larger than remainder, sponda extended beyond protibial border ( Fig. 212 ). 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 with 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 less than 2 times diameter, 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 weakly emarginate, surface densely, finely punctured. Genitalia with basal lobe 5/6 length of paramere, sides convergent, apex obliquely rounded; paramere Unm type, wide, widened apically, apex obliquely truncate ( Fig. 213, 214 ); sipho robust, curved in basal 2/3, basal capsule with inner arm long, wide, apex irregularly obliquely truncate, outer arm slightly longer than inner arm, slender, not widened apically, with accessory piece, basal border broadly, shallowly emarginate ( Fig. 215, 216 ).

Female. Unknown.

Variation. Unknown.

Type material. Holotype male; Venezuela, Bolivar, Carr? (illegible), Sta. Elena de V. - Pau ??, 11-IX- 1977, B. Bechyne leg. ( MIZA).

Remarks. This Venezuelan species has the obliquely truncate parameral apex similar to S. modesta , but is distinguished within this group by the large elytral spots and Venezuelan type locality.
