Canepari, Claudio Hanley, Guy A. Insecta Mundi 2013 2013-02-14 2013 278 1 150   91.   Serratitibia jacquelineGordon and Canepari, new species  Description. Male holotype. Length 2.6 mm, width 2.0 mm; body oval, convex. Dorsal surface shiny, without alutaceous sculpture except pronotum faintly alutaceous. Color yellow; pronotum yellow except large, black basomedial macula extended 2/3 distance to anterior pronotal margin, apex of macula broadly, triangularly emarginate; elytron yellow, narrowly bordered with black, sutural border slightly widened in anterior 1/2, with 1 small, dark brown spot on humerus extended from base just across humeral callus, and very small spot on lateral margin at apical declivity ( Fig. 510); venter of head, prosternum, meso–, metaventrites dark reddish brown; abdomen reddish 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 diameter or less; elytral punctures as large as on pronotum, separated by 1–2 times diameter; metaventral punctures larger than on elytra, separated by diameter or less medially, larger laterally. Clypeus truncate apically, lateral angle abruptly rounded. Eye canthus about 6 eye facets long, straight, apically rounded, yellow. Pronotum narrowed from base to apex, basal angle broadly rounded, anterior angle abruptly rounded, lateral margin straight, basal margin without trace of bordering line. Epipleuron narrow, weakly grooved, deeply emarginate for reception of femoral apices. Protibia with narrow flange, flange less than 1/2 as wide as remainder of protibia, outer margin smooth, straight, sponda extended beyond protibial border ( Fig. 511). Carinae on prosternal process narrowly separated at apex, parallel, joined at basal 1/8 of prosternum, connected to base by short stem. Metaventrite without setal tuft. Basal abdominal ventrite without median setal tuft. Abdomen without primary pores between ventrites 4–5; postcoxal line on basal abdominal ventrite angled to posterior ventrite margin, slightly flattened along margin, apex extended forward. Abdominal ventrites 1–4 with short, sparse pubescence, punctures on basal 2 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 1/2 length of paramere, sides weakly convergent, apex rounded, paramere Unmtype, slender, slightly widened apically, apex rounded ( Fig. 512, 513); sipho robust, strongly curved in basal 2/3, basal capsule with inner arm long, slender, narrowed medially, apex rounded, outer arm short, slightly longer than inner arm, wide, with accessory piece, basal border broadly, shallowly emarginate ( Fig. 514, 515).  Female. Similar to male except head with frons irregularly reddish brown, triangular yellow spot present at middle of frons, pronotum with basomedial macula extended almost to anterior pronotal margin. Genitalia with spermathecal capsule long, slender, cornu slightly enlarged; bursal cap broadly rounded, with 2 arms, apical strut short, widened in apical 3/4 ( Fig. 516).  Variation. Length 2.6–2.7 mm. Elytron variable from almost entirely yellow with black border, to having suture with large, black spot in basal 1/2, or with large, transverse black macula in basal 1/2 extended across entire elytron, isolating a large, yellow, scutellar spot.   Type material.  Holotypemale; Ecuador, Napo Prov.,  2000m, 7km S. Baeza,  20-28.II.1979, H. and A. Howden( USNM).  Paratypes; 6, 5, same data as holotype ( USNM); 1, Ecuador, Napo, Baeza,  2000m,  5.III.1979, S. Marshall( USNM).   Remarks. This species is nearly identical to  S. joan, a species that has a serrate protibia and primary abdominal pores. The type locality for both species is identical, and both holotypesand many of the paratypeswere collected together on the same date by the same collectors. 1979-02-20 1979-02-28 1979-02-20 USNM S.
