2. Serratitibia donna Gordon and Canepari , new species

Description. Male holotype. Length 3.3 mm, width 2.6 mm; body rounded, slightly elongate, convex. Dorsal surface shiny, lacking alutaceous sculpture. Color yellow; pronotum with short, narrow, black, basomedial macula, anterior margin of macula irregular, medially projecting, extended anteriorly 1/5 distance to pronotal apex medially; elytron black with 5 large, yellow spots arranged in transverse rows of 2 each, with apical spot irregularly rounded ( Fig. 66 ); venter of head, median 1/5 of prosternum pale brownish yellow, epipleuron between foveae, meso–, metaventrites dark reddish brown; abdomen yellow except median 1/3 of ventrites 1–3 brownish yellow. Head punctures small, separated by less than diameter, each puncture as large as 2 eye facets; pronotal punctures smaller than head punctures, separated by less than 2 times diameter; elytral punctures equal in size to pronotal punctures, separated by less than 3 times diameter; metaventral punctures larger than on elytra, separated by diameter or less medially, larger and separated by less than diameter laterally. Clypeus weakly emarginate, lateral angle abruptly rounded. Eye canthus short, about 4 eye facets long, angled forward, apically acute, yellow. Pronotum narrowed from base to apex, basal angle broadly rounded, anterior angle abruptly rounded, lateral margin weakly rounded, basal margin with trace of bordering line in lateral 1/2. Epipleuron narrow, deeply grooved, deeply emarginate for reception of femoral apices. Protibial flange about as wide as remainder of protibia, outer margin arcuate, with about 10 teeth, teeth small in basal 1/2, larger in apical 1/2, sponda extended beyond protibial border. Carinae on prosternal process narrowly separated at apex, nearly parallel, joined at basal 1/5, connected to base by short stem. Metaventrite with setal tuft. Basal abdominal ventrite with median setal tuft ( Fig. 71 ). Abdomen with primary pores laterally between ventrites 4– 5 large, extended under apical 1/3 of ventrite 4; postcoxal line on basal abdominal ventrite arcuate throughout, apex extended forward. Abdominal ventrites 1–4 with short, sparse pubescence, punctures on basal 2 ventrites separated by about diameter medially, becoming smaller and dense laterally, ventrites 3–5 densely punctured throughout; 5 th ventrite depressed medially in apical 1/2, apical border emarginate medially, lateral angle of emargination pronounced with small tubercle bearing tuft of dense setae; 6 th 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 feebly rounded, nearly truncate, surface densely, finely punctured. Genitalia with basal lobe 2/3 length of paramere, slightly tapered to apex, apex feebly rounded; paramere Unm type, widened apically, apex rounded ( Fig. 67, 68 ); sipho robust, curved in basal 1/2, basal capsule large, inner arm short, wide, apex rounded, outer arm wide, slightly shorter than inner arm, with accessory piece, basal border deeply emarginate ( Fig. 69, 70 ).

Female. Similar to male except pronotum with median black area enlarged, narrow, nearly reaching anterior pronotal margin, with small, median, apical emargination, elytron lacking yellow humeral spot. Genitalia with spermatheca long, slender, curved medially, widened from base to cornu; bursal cap with 3 arms, apical strut long, robust, apex spatulate in lateral view ( Fig. 72 ).

Variation. Length 3.0– 3.5 mm, width 2.5–2.7 mm. Elytron with apical spots slightly variable in size, apical spot sometimes weakly emarginate on anterior margin. Specimens not designated as type material differ only slightly in form of male genitalia from the type specimens, but have the same size and nearly all yellow male pronotum as the types, except for Brazilian specimens that are less 3.0 mm long.

Type material. Holotype male; Peru, Satipo , V-VI,1941, Paprzycki ( USNM) . Paratypes; 106, same data as holotype except other dates X, XI ( USNM) .

Geographical distribution. Bolivia, Brazil, Peru.

Other specimens. 9. Bolivia. Mapiri . Brazil. Entre Rios, Acc. No. 2966, June ; Para , Belém, IX.1964, E. Dente ; Para , Acc. No. 2966, June ; Santarem , Acc.

Remarks. Large size and almost completely yellow male pronotum distinguish S. donna from other species having the same male genitalia type.

Amazingly large numbers of this species (106 specimens), S. satipoensis (300 specimens) and S. paprzycki were collected by Paprzycki at Satipo, Peru, from 1941 through 1942.
