12. Serratitibia angela Gordon and Canepari , new species

Description. Male holotype. Length 2.7 mm, width 2.0 mm; body broadly rounded, convex. Dorsal surface shiny, lacking alutaceous sculpture. Color yellow; pronotum with small, black basomedial macula extended 1/2 distance to anterior pronotal margin, anterior margin of macula sinuate; elytron black with 5 small, yellow spots in rows of 2 each with single apical spot, mediolateral spot round, apical spot slightly ovate, nearly round ( Fig. 119 ); venter of head, prosternum, meso–, metaventrites brown; abdomen yellow. 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 less than 2 times diameter; elytral punctures larger than on pronotum, separated by 1–3 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, apically rounded, yellow. Pronotum narrowed from base to apex, basal angle broadly rounded, anterior angle abruptly rounded, lateral margin rounded, basal margin with trace of bordering line. Epipleuron narrow, deeply grooved, deeply emarginate for reception of femoral apices. Protibial flange as wide as remainder of protibia, outer margin arcuate, with about 8 short, indistinct teeth from base to apex, sponda extended beyond protibial border. Carinae on prosternal process narrowly separated at apex, weakly convergent, joined at basal 1/8, 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 3/8 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, separated by less than diameter medially, 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 feebly rounded, surface densely, finely punctured. Genitalia with basal lobe 1/2 length of paramere, sides weakly convergent, apex obliquely truncate; paramere Unm type, wide, widened apically, apex rounded ( Fig. 120 ); sipho robust, curved in basal 2/3, basal capsule with inner arm long, wide, apex slightly rounded, outer arm slightly longer than inner arm, with accessory piece, basal border deeply emarginate ( Fig. 121, 122 ).

Female. Unknown.

Variation. Length 2.4–2.7 mm, width 1.8–2.0 mm. Size of elytral spots somewhat variable.

Type material. Holotype male; Brazil, Amazons , (second line of first label and entire second illegible) ( ZMHB).

Other specimens. 5. Brazil. Amazon, Stauding (Staudinger) ( ZMHB); R. Madeira to St. Antonio, Amazons (Trail), 97-71, Cleothera 10-signata Muls; 19., Teffe, 19.10.74., Amazons, (Trail) 97-71, Cleothera 2-4-pustulata Muls.; 7., Serapa. 25.4.74, Amazons. (Trail) 97-71. ( BMNH).

Remarks. Males of this species may be recognized by the small, apically sinuate, mediobasal macula on the pronotum, if the character proves to be consistent. All specimens recorded under “Other specimens” are almost certainly S. angela , but are not designated as paratypes because of differences in size of elytral spots.
