11. Serratitibia shirley Gordon and Canepari , new species

Description. Male holotype. Length 3.0 mm, width 2.5 mm; body broadly oval, convex. Dorsal surface shiny, lacking alutaceous sculpture except pronotum feebly alutaceous. Color yellow; pronotum with large, wide, black basomedial macula extended 3/4 distance to anterior pronotal margin, anterior margin of macula rounded, slightly indented with yellow; elytron black with 5 large, yellow spots in rows of 2 each with single apical spot, mediolateral spot projected inward, apical spot transversely rectangular, apically emarginate ( Fig. 113 View Figures 108–122. 108–112 ); venter of head, prosternum, meso–, metaventrites black; abdomen yellowish brown. Head punctures small, separated by less than diameter, each puncture as large as 1 eye facet; pronotal punctures equal in size to head punctures, separated by less than 2 times diameter; elytral punctures larger than on pronotum, separated by less than 2 times diameter; metaventral punctures larger than on elytra, separated by less than diameter medially, larger laterally. Clypeus weakly emarginate apically, lateral angle abruptly rounded. Eye canthus about 6 eye facets long, 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, deeply grooved, deeply emarginate for reception of femoral apices. Protibial flange as wide as remainder of protibia, outer margin arcuate, with about 4 short, rounded teeth restricted to basal 1/2, sponda extended beyond protibial border. Carinae on prosternal process widely separated at apex, convergent, joined at basal 1/4, forming triangle. Metaventrite without setal tuft. Basal abdominal ventrite with median setal tuft. Abdomen with primary pores laterally between ventrites 4–5 small, extended under apical 1/4 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, separated by less than diameter medially, 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 rounded, surface densely, finely punctured. Genitalia with basal lobe nearly as long as paramere, sides weakly convergent, apex obliquely truncate; paramere Unm type, slender, widened apically, apex rounded ( Fig. 114, 115 View Figures 108–122. 108–112 ); sipho robust, curved in basal 2/3, basal capsule with inner arm short, wide, apex rounded, outer arm shorter than inner arm, outer margin sinuate, with accessory piece, basal border weakly emarginate ( Fig. 116, 117 View Figures 108–122. 108–112 ).

Female. Similar to male except head with clypeus and apex of frons dark brown, pronotum with basomedial macula large, extended to anterior pronotal margin, elytron with humeral spot as in male. Genitalia with spermathecal capsule short, widened from base to apex; bursal cap triangular, with 3 distinct arms, apical strut long, slender, apex spatulate in lateral view ( Fig. 118 View Figures 108–122. 108–112 ).

Variation. Length 2.3–3.0 mm, width 1.8–2.5 mm. Male pronotum with mediobasal spot often nearly reaching anterior pronotal margin, apical margin of spot weakly to very deeply indented with yellow, elytral spots somewhat variable in size, humeral and mediolateral spots occasionally connected, male specimens of from Espiritu Santo tend to have the mediobasal pronotal macula deeply incised with yellow at apex.

Remarks. This is a remarkably distinctive species within a group of similar-appearing congeners. It is distinguished by elytron with inwardly projecting, mediolateral spot, males with basomedial pronotal macula often extended to apical pronotal margin, or nearly so, female clypeus and apex of frons dark brown, and female elytron with humeral spot present.
