description: 53. Serratitibia tammy Gordon and Canepari, new species   
 Description. Female holotype. Length 3.0 mm, width 2.5 mm; body oval, convex. Dorsal surface shiny, lacking alutaceous sculpture. Color yellow; pronotum with large, dark brown, basomedial macula extended 3/4 distance to anterior pronotal margin, apex weakly, indistinctly emarginate with yellow; elytron with sutural and apical margins with narrow brown border and 2 dark brown spots, anterior spot large, irregularly transverse, posterior spot smaller, irregularly triangular (Fig. 336); venter of head, prosternum, mesoventrite pale reddish brown, metaventrite dark brown; abdomen reddish yellow. 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 as large as on pronotum, separated by 1–3 times diameter; metaventral punctures larger than on elytra, separated by diameter or less medially, slightly 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, deeply grooved, deeply emarginate for reception of femoral apices. Protibial flange as wide as remainder of protibia, outer margin arcuate, with about 8 small teeth throughout, sponda extended beyond protibial border. Carinae on prosternal process widely separated at apex, convergent, joined at basal 1/6 of prosternum, connected to base by short stem. Postcoxal line on basal abdominal ventrite angled to posterior ventrite margin, flattened along margin, apex extended forward; primary pores between ventrites 4–5 large, extended under apical 1/2 of ventrite 4. Abdominal ventrites 1–6 with short, sparse pubescence, punctures on basal 3 ventrites large medially, separated by diameter or less, becoming smaller and dense laterally, ventrites 3–6 more densely, finely punctured throughout. Genitalia with spermathecal capsule long, wide, curved medially, cornu enlarged; bursal cap broadly triangular, with 3 arms, inner arm faint, apical strut short, wide, apex spatulate in lateral view (Fig. 337).   
 Male. Unknown.   
 Variation. The specimen listed as “other specimen” is much smaller than the types, and the spermathecal capsule is slightly different in thickness, but it matches the types well in color pattern and protibial structure.   
 Type material. Holotype female; (Brazil) Porto Velho, Bras. Xii.54 (USNM). Paratype; 1, same data as holotype (USNM).   
 Other specimen. 1. Brazil, Amazonas, Tefe, XII–1961, F. M. Oliveira. (MZSP).   
 Remarks. Serratitibia tammy has an elytral pattern slightly resembling specimens of S. kathleen from Trinidad, but the latter species has both elytral spots highly irregular, the result of coalescing of normally discrete spots.
