60. Serratitibia nicole Gordon and Canepari , new species

Description. Female holotype. Length 2.4 mm, width 1.9 mm; body oval, convex. Dorsal surface shiny, lacking alutaceous sculpture. Color yellow; pronotum with 5 brown spots, 3 along base feebly connected, 2 triangular spots medially on disc; elytron with sutural, apical, and lateral margins with narrow brown border, sutural border widened on disc, 4 brown spots on each elytron, 1 irregularly elongate, oval, apically curved spot on disc near suture, 1 large, elongate spot on humerus, 1 small, elongate, oval spot on apical declivity near suture, 1 irregularly oval spot near lateral margin on apical declivity ( Fig. 352 ); venter of head, prosternum pale reddish brown, meso–, metaventrites dark reddish brown; abdomen yellow. Head punctures small, separated by diameter or less, each puncture as large as 1–2 eye facets; pronotal punctures as large as head punctures, separated by less than diameter; elytral punctures as large as on pronotum, separated by less than 2 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 with trace of bordering line. Epipleuron narrow, deeply grooved, deeply emarginate for reception of femoral apices. Protibial flange narrower than remainder of protibia, outer margin slightly arcuate, sinuate, 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 1/3 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 short, wide, curved medially, cornu enlarged; bursal cap broadly rectangular, with 3 arms, inner arm faint, apical strut long, slender, apex spatulate in lateral view ( Fig. 353 ).

Male. Unknown.

Variation. Unknown.

Type material. Holotype female; Bolivia, Huachi, Rio Beni, IX, WMMann, Mulford BioExpl 1921–2 ( USNM).

Remarks. The elytral color pattern is distinctive for S. nicole . The pattern of 4 small brown spots with inner apical spot curved, or hooked at apex is not found elsewhere in Serratitibia , although somewhat similar to that of S. judy .
