51. Serratitibia judith Gordon and Canepari , new species

Description. Male holotype. Length 2.2 mm, width 1.8 mm; body oval, convex. Dorsal surface shiny, lacking alutaceous sculpture. Color yellow; pronotum with large, black basomedial macula extended 2/3 distance to anterior pronotal margin, apex of macula broadly, weakly triangularly incised with yellow; elytron black with 5 small yellow spots arranged in rows of 2 each with apical spot, mediolateral spot irregularly triangular, apical spot transversely triangular ( Fig. 326 View Figures 315–331. 315–320 ); ventral surface entirely pale yellowish brown. Head punctures small, separated by diameter or less, each puncture as large as 1 eye facet; pronotal punctures larger than head punctures, separated by diameter or less; elytral punctures as large as on pronotum, separated by diameter or less; metaventral punctures larger than on elytra, separated by diameter or less medially, larger laterally. Clypeus weakly emarginate apically, lateral angle abruptly rounded. Eye canthus about 6 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 straight, basal margin without trace of bordering line. Epipleuron narrow, weakly grooved, deeply emarginate for reception of femoral apices. Protibial flange about as wide as remainder of protibia, outer margin arcuate, with about 8 small teeth throughout, sponda extended beyond protibial border. Carinae on prosternal process narrowly separated at apex, weakly convergent, joined at basal 1/6 of prosternum, connected to base by short stem. Metaventrite without setal tuft. Basal abdominal ventrite with median setal tuft. Abdomen with primary pores laterally between ventrites 4–5 small, extended under apical 1/8 of ventrite 4; 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 feebly emarginate, surface densely, finely punctured. Genitalia with basal lobe 3/4 as long as paramere, sides slightly convergent, apex obliquely rounded; paramere Unm type, extremely wide, wider than posterior 1/3 of phallobase, nearly rectangular, apex truncate ( Fig. 327, 328 View Figures 315–331. 315–320 ); sipho robust, strongly curved in basal 1/2, basal capsule with inner arm short, wide, tapered to truncate apex, outer arm slightly longer than inner arm, wide, with accessory piece, basal border broadly, shallowly emarginate ( Fig. 329, 330 View Figures 315–331. 315–320 ).

Female. Similar to male except pronotum with basomedial macula large, extended nearly to anterior pronotal margin, elytron without humeral spot. Genitalia with spermathecal capsule long, abruptly curved at basal 1/3, weakly curved in apical 2/3, cornu slightly enlarged; bursal cap rounded, with 3 arms, inner arm faint, apical strut long, apex slightly widened in lateral view ( Fig. 331 View Figures 315–331. 315–320 ).

Variation. Length 2.0– 2.2 mm, width 1.7–1.8 mm.

Type material. Holotype male; Colombia, Leticia , Via Los Lagos, 50 m, 2-IX-2008, Leg. ( R. Westerduijn), flood plain forest ( ICN) . Paratypes; 9, same data as holotype ( GGC) ( ICN) ( JEBC) ( MDC) .

Remarks. This little species is characterized by a combination of small size, mediolateral and apical spots on elytra irregularly triangular, venter entirely pale yellowish brown, and male genitalia with an extremely large, rectangular paramere.
