68. Serratitibia jennifer Gordon and Canepari , new species

Description. Male holotype. Length 2.4 mm, width 1.9 mm; body slightly elongate, convex. Dorsal surface shiny, lacking alutaceous sculpture. Color yellow; pronotum with small, narrow, black basomedial macula extended anteriorly 1/4 distance to pronotal apex, anterior border of macula arcuately emarginate; elytron black with 5 small, yellow spots arranged in transverse rows of two each plus one at apex, humeral spot extended along lateral elytral margin, broadly connected to mediolateral spot, mediolateral spot barely perceptibly connected to apical spot, discal spot round, located just anterior to apical declivity, apical spot transversely oval ( Fig. 385 ); meso–, metaventrites brown; abdomen yellowish brown. Head punctures small, separated by less than diameter, each puncture as large as 4 eye facets; pronotal punctures smaller than on head, separated by less than 2 times diameter; elytral punctures equal in size to pronotal punctures, separated by less than 3 times diameter. Clypeus apically truncate, 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, 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 5 large teeth, sponda extended beyond protibial border. Carinae on prosternal process narrowly separated at apex, gradually joined just before prosternal base. Metaventrite without setal tuft. Basal abdominal ventrite with median setal tuft. Abdomen without primary pores laterally between ventrites 4–5; postcoxal line on basal abdominal ventrite rounded throughout, 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 tubercle bearing tuft of dense setae; 6th ventrite short, narrow, weakly depressed in apical 1/2, depression glabrous, with 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 ( Fig. 386, 387 ); sipho robust, wide, curved in basal 3/4, basal capsule with inner arm short, apex obliquely truncate, outer arm 3 times as long as inner arm, with accessory piece, basal border weakly emarginate ( Fig. 388, 389 ).

Female. Similar to male except pronotum with median black area large, nearly reaching anterior pronotal margin, apically truncate, elytron lacking yellow humeral spot, mesepimeron brown. Genitalia with spermatheca long, slender, weakly curved, cornu slightly enlarged; bursal cap with 3 arms, apical strut short, narrow, slightly widened apically ( Fig. 390 ).

Variation. Length 2.2–2.5 mm, width 1.7–2.0 mm. Elytron with humeral spot broadly or narrowly connected to median spot along elytral border, or briefly extended along lateral border, not connected to median spot.

Type material. Holotype male; Brazil, PA (Para), Utinga , Belém, 10.X.1962, J. Bechyné col., Convenio DZSP-Goeldi ( MZSP) . Paratypes; 11, 6, same data as holotype ( MZSP) ; 2, Brazil, PA, Marituba , Sta. Isabel do Pará, 17.VIII.1962, J. Bechyné col, Convenio DZSA-Goeldi ( MZSP) ; 3, Brazil, Rio de Jan , June, Jan., without date, Acc. No. 2066, Oct. ( CMNH) .

Remarks. Serratitibia jennifer resembles S. elizabeth (see remarks under S. elizabeth ). Serratitibia jennifer is distinguished from that species by male pronota with a short, wide, basal macula, a tendency for the lateral spots to form a continuous, yellow lateral border, and presence of a setal tuft on the male basal abdominal ventrite.
