67. Serratitibia elizabeth Gordon and Canepari , new species

Description. Male holotype. Length 2.1 mm, width 1.6 mm; body slightly elongate, convex. Dorsal surface shiny, lacking alutaceous sculpture. Color yellow; pronotum with small, dark brown, basomedial macula wide basally, extended anteriorly 2/3 distance to pronotal apex at middle, apex shallowly emarginate with yellow; elytron black with 5 small, yellow spots arranged in transverse rows of two each plus one at apex, discal spot small, located just anterior to apical declivity, apical spot transversely oval ( Fig. 381 ); prosternum, meso–, metaventrites light brown to dark brown; abdomen yellowish brown. Head punctures small, separated by less than diameter, each puncture as large as 1–2 eye facets; pronotal punctures larger than on head, separated by diameter or less; elytral punctures equal in size to pronotal punctures, separated by less than 2 times diameter. Clypeus apically truncate, lateral angle abruptly rounded. Eye canthus about 4 eye facets long, angled forward, apically rounded, yellow. Pronotum narrowed from base to apex, basal angle broadly rounded, anterior angle abruptly rounded, basal margin without bordering line. Epipleuron narrow, grooved, deeply emarginate for reception of femoral apices. Protibial flange wider than remainder of protibia, outer margin arcuate with about 6 large teeth, sponda extended beyond protibial border. Carinae on prosternal process narrowly separated at apex, nearly parallel, joined just before prosternal base. Metaventrite without setal tuft. Basal abdominal ventrite without median setal tuft. Abdomen without primary pores laterally between ventrites 4–5; postcoxal line on basal abdominal ventrite straight in basal 1/3, flat along apical margin of ventrite, apex extended forward. Abdominal ventrites with short, sparse pubescence, punctures on basal 3 ventrites separated by about diameter medially, becoming smaller and dense laterally, ventrites 3–5 densely punctured throughout; 5th ventrite depressed medially in apical 1/2, apical margin weakly emarginate medially, lateral angle of emargination with small tubercle bearing tuft of dense setae; 6th ventrite short, narrow, weakly depressed in apical 1/2, depression glabrous, without median tubercle, apical margin widely, shallowly emarginate, angle on each side of emargination abruptly rounded, bearing small tuft of dense setae. Apical tergite short, narrow, apex arcuate, surface densely, finely punctured. Genitalia with basal lobe shorter than paramere, tapered to rounded apex; paramere Unm type, widened apically, apex slightly rounded; sipho robust, wide, curved in basal 1/2, basal capsule with inner arm elongate, slender, outer arm as long as inner arm, with accessory piece, basal border deeply emarginate ( Fig. 382, 383 ).

Female. Similar to male except pronotum with median black area apically truncate, nearly reaching anterior pronotal margin, elytron lacking yellow humeral spot. Genitalia with spermatheca long, slen- der, weakly curved, cornu slightly enlarged; bursal cap with 3 arms, apical strut narrow ( Fig. 384 ).

Variation. Length 1.9–2.0 mm, width 1.4–1.7 mm. Elytron with discal spot very small, yellow or red, distinct or nearly completely absent.

Type material. Holotype male; Brazil, AM (Amazonas), Rio Cauaburi , 7-8.XII.1962, J. Bechyné col., Convenio DZSP-Goeldi ( MZSP) . Paratypes, 5; 4, same data as holotype ( MZSP) ; 1, Brazil, Barueri, Sao Paulo-Brasil, XII.965, K. Lenko col ( MZSP) .

Remarks. This species resembles S. jennifer , another Brazilian taxon (See remarks under S. jennifer ). However, S. elizabeth is distinguished by its small size, discrete elytral spots, discal spot on elytron very small or nearly absent, and Brazilian type locality.
