92. Serratitibia lori Gordon and Canepari , new species

Description. Male holotype. Length 2.0 mm, width 1.5 mm; body oval, convex. Dorsal surface shiny, lacking alutaceous sculpture. Color yellow; pronotum with large, black basomedial macula extended nearly 3/4 distance to anterior pronotal margin, apex of macula weakly, broadly indented with yellow; elytron black with 2 yellow spots, humeral spot small, discal spot small, obliquely triangular ( Fig. 517 ); venter of head, prosternum reddish yellow, meso–, metaventrites dark brown; abdomen brownish yellow. Head punctures small, separated by diameter or less, each puncture as large as 2 eye facets; pronotal punctures as large as head punctures, separated by diameter or less; elytral punctures larger than on pronotum, separated by 1–2 times diameter; metaventral punctures much larger than on elytra, separated by diameter or less medially, larger laterally. Clypeus weakly emarginate apically, lateral angle abruptly rounded. Eye canthus about 4 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 without trace of bordering line. Epipleuron narrow, deeply grooved, deeply emarginate for reception of femoral apices. Protibia with outer margin weakly flanged, flange smooth, without serrations, 1/3 as wide as remainder of protibia, sponda extended beyond protibial border. Carinae on prosternal process widely separated at apex, convergent, joined at basal 7/8 of prosternum, connected to base by short stem. Metaventrite without setal tuft. Basal abdominal ventrite without median setal tuft. Abdomen without primary pores; postcoxal line on basal abdominal ventrite angled to posterior ventrite margin, flattened 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 broadly, weakly rounded, surface densely, finely punctured. Genitalia with basal lobe 3/4 as long as paramere, slender, sides weakly convergent, apex obliquely rounded; paramere Unm, short, slender, slightly widened apically, apex rounded ( Fig. 518, 519 ); sipho robust, strongly curved in basal 2/3, basal capsule with inner arm long, slender, narrowed medially, apex rounded, outer arm slightly longer than inner arm, slender, with accessory piece, basal border broadly, deeply emarginate ( Fig.520, 521 ).

Variation. Unknown.

Type material. Holotype male. Brazil, Am. Reserva Ducke, 26km NE Manaus , Hurtado, J. C. G., Eschweilera wachenheirii , 01.iv.1966, Tree No. 108, Tray No. 9, C97.35 , BMNH ( B) 2003-84 ( BMNH).

Remarks. Serratitibia lori is similar to S. rachel in dorsal color pattern, but is smaller and does not have abdominal primary pores. The discal elytral spot is small, yellow, triangular, and the male paramere has a basal lobe 3/4 as long as the paramere.
