45. Serratitibia gloria 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, black basomedial macula extended slightly more than 1/2 distance to anterior pronotal margin, apex of macula emarginate with yellow; elytron black with 5 large, yellow spots arranged in rows of 2 each with apical spot, borders of all spots blurred, not crisply defined, mediolateral spot small, irregularly oval, set back from lateral elytral margin, apical spot transversely triangular ( Fig. 295 ); venter of head, prosternum, meso–, metaventrites dark brown; abdomen yellowish brown. Head punctures small, separated by less than diameter, each puncture as large as 2 eye facets; pronotal punctures as large as head punctures, separated by less than diameter; elytral punctures larger than on pronotum, separated by 1–2 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, 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 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 small teeth throughout, sponda extended beyond protibial border. Carinae on prosternal process widely separated at apex, strongly 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 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, 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 3/4 length of paramere, sides weakly convergent, apex obliquely truncate; paramere Unm type, wide, widened apically, apex truncate ( Fig. 296, 297 ); sipho robust, strongly curved in basal 2/3, basal capsule with inner arm short, wide, apex obliquely truncate, outer arm slightly longer than inner arm, slender, with accessory piece, basal border broadly, shallowly emarginate ( Fig. 298, 299 ).

Female. Similar to male except head dark reddish brown, basomedial pronotal macula extended to anterior pronotal margin, elytron without humeral spot. Genitalia with spermathecal capsule slender, curved medially, cornu slightly enlarged; bursal cap rounded, with 3 arms, inner arm faint, apical strut short, apex hooked ( Fig. 300 ).

Variation. Length 3.0– 3.3 mm, width 2.4–2.6 mm. Color pattern on elytron varies from typical to having the scutellar, discal, and mediolateral spots narrowly connected, or with discal, mediolateral, and apical spots narrowly connected.

Type material. Holotype male; Brazil, Corcovado , Rio de Janeiro, G. E. Bryant, 15.V.1912, G. Bryant Coll. 1919-147, Cleothera bis-quinque-pustulata (Fab.) Muls. ( BMNH) . Paratypes: 2, 1, Brazil, 17833, Fry Rio Jan. , Fry Coll. 05.100 ( BMNH) ; 1, Brazil, VIII 1901, C. Bruch, (label illegible), Cleothera trivialis Muls. , ex. Coll. J. Weise ( ZMHB) .

Remarks. Serratitibia gloria is distinguished by an unusual elytral color pattern. The pattern is basically the same as many other species, but spot outlines are blurred, not crisply defined, blending with the surrounding surface color. The small, transversely oval, mediolateral spot is widely removed from the lateral elytral border, and there is a strong tendency for all spots to coalesce.
