50. Serratitibia ashley Gordon and Canepari , new species

Description. Male holotype. Length 2.5 mm, width 2.0 mm; body oval, convex. Dorsal surface shiny, lacking alutaceous sculpture. Color yellow; pronotum with large, black basomedial macula extended slightly more than 1/2 distance to anterior pronotal margin, apex of macula deeply, triangularly incised with yellow; elytron black with 5 large yellow spots arranged in rows of 2 each with apical spot, mediolateral spot elongately oval, apical spot transversely oval except anterior border straight ( Fig. 321 ); venter of head, prosternum, meso–, metaventrites dark brown; abdomen dark brown. Head punctures small, separated by diameter or less, each puncture as large as 1 eye facet; 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 larger than on elytra, separated by diameter or less medially, larger laterally. Clypeus weakly emarginate apically, lateral angle abruptly rounded. Eye canthus about 5 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, parallel, joined at basal 1/4 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 large, extended under apical 1/3 of ventrite 4; postcoxal line on basal abdominal ventrite angled to posterior ventrite margin, flattened along margin, apex very slightly 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 truncate, surface densely, finely punctured. Genitalia with basal lobe slender, as long as paramere, sides parallel, apex obliquely rounded; paramere Unm type, wide, widened apically, apex truncate ( Fig. 322, 323 ); sipho robust, strongly curved in basal 2/3, basal capsule with inner arm elongate, slender, apex truncate, outer arm slightly longer than inner arm, wide, with accessory piece, basal border broadly, shallowly emarginate ( Fig. 324, 325 ).

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, curved medially, cornu slightly enlarged; bursal cap rounded, with 3 arms, inner arm faint, apical strut short, apically spatulate in lateral view.

Variation. Length 2.3–2.5 mm, width 1.8–2.0 mm. The specimen from Peru is not designated a paratype because the basal lobe of the male genitalia is slightly wider than that of the holotype.

Type material. Holotype male; Colombia, Fusagasugá, Cnd (Cundinamarca), 12. V.40, Murillo No 93 ( USNM) . Paratypes; 3, Arbaláez, Cnd, 31.I.40, Murillo No 75 ( USNM) .

Other specimen. 1. Peru, 13-guttata Muls. ( ZMHB).

Remarks. This species is distinguished from many similar appearing taxa by a combination of Colombian type locality, large elytral spots, mediolateral spot distinctly elongate oval, and lack of a median tubercle on the male 6th abdominal ventrite.
