85. Serratitibia cheryl 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 yellow except a faint, narrow, pale brown line on each side of disc medially; elytron black with 5 large, yellow spots arranged in rows of 2 each with apical spot, scutellar, humeral and mediolateral spots broadly connected, mediolateral spot oval, apical spot transversely oval ( Fig. 474 ); venter of head, prosternum pale reddish yellow, meso–, metaventrites reddish brown; abdomen yellow. Head punctures small, separated by diameter or less, each puncture as large as 1 eye facet; pronotal punctures as large as head punctures, separated by diameter or less; elytral punctures as large as on pronotum, separated by 1–3 times diameter; metaventral punctures larger than on elytra, separated by less than diameter medially, larger laterally. Clypeus weakly emarginate apically, lateral angle abruptly rounded. Eye canthus about 6 eye facets long, straight, angled forward, apex acute, 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, deeply grooved, deeply emarginate for reception of femoral apices. Protibial flange wider than remainder of protibia, outer margin straight, with 7 large teeth medially, sponda extended beyond protibial border. Carinae on prosternal process narrowly separated at apex, parallel, 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; 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 small medially, separated by diameter or less, equal in size but becoming 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 truncate, surface densely, finely punctured. Genitalia with basal lobe slightly more than 1/2 length of paramere, sides convergent, apex obliquely truncate; paramere Unm type, wide, slightly widened apically, apex truncate ( Fig. 475, 476 ); sipho robust, strongly curved in basal 2/3, basal capsule with inner arm long, slender, narrowed medially, apex wide, obliquely truncate, outer arm slightly longer than inner arm, slender, curved, with accessory piece, basal border broadly, deeply emarginate ( Fig. 477, 478 ).

Female. Unknown.

Variation. Unknown.

Type material. Holotype male; British Guiana (Surinam), Orinoque and New River Heads, 1938, H. Beddington, B.M. 1938-346 ( BMNH).

Remarks. This species is distinguished by the large size, almost entirely yellow pronotum, and large, partially fused elytral spots. It is somewhat similar to S. joyce (Section I), another species known from Surinam, but S. joyce has a basal pronotal macula and discrete elytral spots.
