57. Serratitibia irene Gordon and Canepari , new species

Description. Female holotype. Length 3.6 mm, width 2.7 mm; body rounded, convex. Dorsal surface with trace of alutaceous sculpture, shiny. Color yellow; pronotum with large, black, basomedial macula extended 7/8 distance to anterior pronotal margin, apical margin of macula triangularly indented with yellow medially; elytron black with 6 large, yellow spots arranged in 2 rows of 2 spots each, plus apical spot, with additional spot present between anterior and posterior rows ( Fig. 346 ); venter of head, prosternum reddish brown, meso–, metaventrites black; abdomen yellow. Head punctures small, separated by diameter or less, each puncture as large as 1–2 eye facets; pronotal punctures equal in size to head punctures, separated by less than 2 times diameter; elytral punctures as large as on pronotum, separated by less than 2 times diameter; punctures on metaventrite large, separated by about diameter medially, becoming larger laterally. Clypeus weakly emarginate apically, nearly truncate, lateral angle rounded. Eye canthus about 6 eye facets long, angled forward, apically rounded, brown. Pronotum narrowed from base to apex, lateral margin straight, basal angle broadly rounded, anterior angle abruptly rounded, basal margin without trace of bordering line. Epipleuron narrow, weakly grooved, deeply emarginate for reception of femoral apices. Protibia with flange as wide as remainder of tibia, arcuate, outer margin with about 12 teeth throughout, teeth larger medially, sponda raised above protibial border. Abdomen with primary pores laterally between ventrites 4–5 small, extended under apical 1/4 of ventrite 4; postcoxal line on basal abdominal ventrite angled to apical margin, flattened along margin, extended anteriorly; ventrites with sparse, long pubescence, basal 3 ventrites with coarse punctures medially separated by diameter or less, ventrites 4–6 with fine, dense punctures. Genitalia with spermathecal capsule long, slender, curved medially, cornu slightly enlarged; bursal cap broadly triangular, with 3 arms, apical strut long, slender, not apically widened ( Fig. 347 ).

Male. Unknown.

Variation. Unknown.

Type material. Female holotype; Ecuador, Napo, vic. Misahualli , ca 1 o 02’S, 77 o 40’W, X–27 to X–31–2002 ( CSCA) .

Remarks. Serratitibia irene , like S. kathy and S. regularis , is unusual because the female has more than 5 yellow spots on each elytron. These species are diagnosed by the number of elytral spots, although spot numbers and size differ considerably between the three.
