65. Serratitibia patricia Gordon and Canepari , new species

Description. Male holotype. Length 2.7 mm, width 2.1 mm; body elongate, convex. Dorsal surface shiny, lacking alutaceous sculpture except head with faint sculpture. Color yellow; vertex of head black; pronotum with black, basomedial macula wide basally, extended anteriorly 2/3 distance to pronotal apex at middle, apex deeply emarginate with yellow; elytron black with 5 large, yellow spots, basal 2 spots on humeral angle and disc at base, middle 2 spots in oblique row, both narrowly connected to apical spot, apical spot transverse, anterior margin deeply emarginate ( Fig. 369 ); venter of head, apical 3/4 of epipleuron, prosternum, meso–, metaventrites black; abdomen yellowish brown. Head punctures small, separated by less than diameter, each puncture as large as 1–2 eye facets; pronotal punctures as large as head punctures, separated by less than 3 times diameter; elytral punctures equal in size to pronotal punctures, separated by less than 3 times diameter. Clypeus weakly emarginate apically, nearly truncate, lateral angle abruptly rounded. Eye canthus about 4 eye facets long, angled forward, apically rounded, yellow. Pronotum narrowed from base to apex, basal angle broadly rounded, anterior angle abruptly rounded, basal margin with trace of bordering line in lateral 1/2. Epipleuron narrow, nearly flat, deeply emarginate for reception of femoral apices. Protibial flange about as wide as remainder of tibia, outer margin arcuate, with teeth nearly absent, faint indication of teeth at tibial base, sponda not extended beyond protibial border. Carinae on prosternal process narrowly separated at apex, nearly parallel, joined just before prosternal base, connected to base by blunt ridge. Metaventrite without setal tuft. Basal abdominal ventrite without median setal tuft. Abdomen without primary pores laterally between ventrites 4–5; postcoxal line on basal abdominal ventrite arcuate throughout, apex extended forward. Abdominal ventrites 1–4 with short, sparse pubescence, punctures on basal 3 ventrites separated by about diameter medially, becoming smaller and dense laterally, ventrites 3–5 densely punctured throughout; 5th ventrite depressed medially on apical border, apical border emarginate medially, lateral angle of emargination pronounced with small tubercle bearing tuft of dense setae; 6th ventrite short, narrow, deeply depressed medially, depression glabrous, without median tubercle, apical margin shallowly emarginate, angle on each side of emargination broadly rounded. Apical tergite short, narrow, apex rounded, surface densely, finely punctured. Genitalia with basal lobe shorter than paramere, slightly tapered to apex, apex feebly rounded; paramere Unm type, widened apically, apex rounded ( Fig. 370, 371 ); sipho robust, curved in basal 1/2, basal capsule large, inner arm short, narrow, rectangular, outer arm wide, longer than inner arm, with accessory piece, basal border deeply emarginate ( Fig. 372, 373 ).

Female. Similar to male except head dark brown with faint, triangular yellow spot at middle of frons, pronotum with median black area enlarged, nearly reaching anterior pronotal margin, with small, median, apical emargination, elytron lacking yellow humeral spot. Genitalia with spermatheca long, slen- der, curved at both ends, cornu not enlarged; bursal cap with 2 outer arms, apical strut short, apex spatulate in lateral view ( Fig. 374 ).

Variation. Length 2.5–2.7 mm, width 1.8–2.1 mm. Elytron with discal spot on suture broadly joined to apical spot, forming a single large, comma shaped spot.

Type material. Holotype male; Ecuador, Napo Prov. 2000m, 7km S. Baeza, 20- 28.11.1979, H. and A. Howden ( USNM) . Paratype; 1, same data as holotype ( USNM) .

Remarks. The Colombian type locality, large elytral spots, and black vertex of male head separate S. patricia from other members of Section II. Protibial teeth are nearly absent, but visible in basal 1/3 of tibia. Male and female genitalia are typical of Serratitibia , not of Cyrea , the only other genus where this species might be placed if the protibial teeth are overlooked.
