74. Serratitibia lisa Gordon and Canepari , new species

Description. Male holotype. Length 2.6 mm, width 2.0 mm; body slightly elongate, convex. Dorsal surface shiny, lacking alutaceous sculpture. Color yellow; clypeal apex black; pronotum with black, basomedial macula wide basally, extended anteriorly 2/3 distance to pronotal apex at middle, apex deeply emarginate with yellow; elytron black with 5 large, yellow spots occupying most of surface, spots arranged in transverse rows of two each plus one at apex, humeral spot small, elongate, sutural and discal spots narrowly connected, apical spot wide ( Fig. 417 ); prosternum, meso–, metaventrites black; abdomen dark brown; trochanters and base of femora brown. Head punctures small, separated by diameter or less, each puncture as large as 2 eye facets; pronotal punctures smaller than head punctures, separated by 1– 3 times diameter, elytral punctures larger than pronotal punctures, separated by 1–4 times diameter. Clypeus weakly emarginate apically, lateral margin rounded, 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 straight, basal margin without bordering line. Epipleuron narrow, weakly grooved, deeply emarginate for reception of femoral apices. Protibial flange as wide as remainder of protibia, outer margin straight with about 10 small teeth, sponda extended beyond protibial border. Carinae on prosternal process narrowly separated at apex, nearly parallel, joined 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, flattened along posterior ventrite margin, angled forward. Abdominal ventrites with short, sparse pubescence, punctures on basal 2 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 pronounced 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 shallowly emarginate, angle on each side of emargination abruptly rounded, bearing small tuft of dense setae. Apical tergite short, narrow, apex weakly arcuate, surface densely, finely punctured. Genitalia with basal lobe shorter than paramere, tapered to rounded apex, sides “pinched” medially; paramere Unm type, widened apically, apex slightly rounded ( Fig. 418, 419 ); sipho robust, curved in basal 1/2, basal capsule with inner arm elongate, apically rounded, outer arm as long as inner arm, with small accessory piece, basal border deeply emarginate ( Fig. 420, 421 ).

Female. Similar to male except head black with small, triangular, yellow macula on lateral margin posterior to clypeus, pronotum with median black area narrowly extended medially to apical pronotal margin, elytron lacking yellow humeral spot, basal 2/3 of femur brown. Genitalia with spermatheca long, slender, strongly curved, cornu slightly enlarged; bursal cap with 3 arms, apical strut long, narrow, only slightly flattened in lateral view ( Fig. 422 ).

Variation. Length 2.4–2.6 mm, width 1.8–2.0 mm. Humeral and median lateral spots may be narrowly connected, scutellar spot narrowly connected to discal spot or distinctly separate.

Type material. Holotype male; Ecuador, Napo, 6.5 km NW Cuyuja , 2300m, 00 o 26.38’S - 076 o 36.25’W., VIII-16-1998, A.J. Gilbert ( CSCA) . Paratypes; 6, same data as holotype ( CSCA) .

Remarks. Serratitibia lisa is most similar to S. nancy , except male with black clypeal apex, black elytral surface with small, elongate humeral spot on male elytron, remainder of spots large, occupying most of elytral surface, trochanters brown, female head black except triangular yellow area next to eye posterior to clypeus, male genitalia with basal lobe not medially “pinched,” inner arm of siphonal capsule short, rectangular, apically truncate; and female genitalia with apical strut long, narrow, not widened apically.
