82. Serratitibia satipoensis Gordon and Canepari , new species

Description. Male holotype. Length 2.3 mm, width 1.8 mm; body elongate, convex. Dorsal surface shiny, lacking alutaceous sculpture. Color yellow; 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 small, yellow spots arranged in transverse rows of two each plus one at apex, apical spot transversely oval ( Fig. 459 ); prosternum, meso–, metaventrites light to dark brown; abdomen brownish yellow. 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 2 times diameter; elytral punctures larger than pronotal punctures, separated by 1 to3 times diameter; metaventrite with median punctures as large as on elytron, separated by about diameter medially, becoming coarser, separated by less than diameter in lateral 1/2. 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 without bordering line. Epipleuron narrow, grooved, deeply emarginate for reception of femoral apices. Protibial flange about as wide as remainder of protibia, outer margin straight with about 4 large teeth in basal 1/2, several minute teeth in apical 1/2, sponda extended beyond protibial border. Carinae on prosternal process narrowly separated at apex, nearly parallel, joined just before prosternal base. 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 straight in basal 1/3, flat along apical margin of ventrite, apex extended forward. Abdominal ventrites 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 in apical 1/2, apical margin weakly emarginate medially, lateral angle of emargination pronounced with small tubercle bearing tuft of dense setae; 6th ventrite short, narrow, depressed in apical 1/2, depression glabrous, with small median tubercle, apical margin widely, shallowly emarginate, angle on each side of emargination abruptly rounded, bearing small tuft of dense setae. Apical tergite short, narrow, apex weakly emarginate, surface densely, finely punctured. Genitalia with basal lobe shorter than paramere, tapered from base to apex, apex rounded; paramere Unm type, wide in apical 1/2, apex truncate ( Fig. 460, 461 ); sipho slender, curved in basal 1/2, basal capsule large, inner arm short, wide, rectangular, outer arm wide, longer than inner arm, with accessory piece, basal border deeply emarginate ( Fig. 462, 463 ).

Female. Similar to male except head brown, pronotum with median black area extended nearly to pronotal apex, apex slightly emarginate, elytron lacking yellow humeral spot. Genitalia with spermatheca long, slender, weakly curved, cornu enlarged; bursal cap with 3 arms, apical strut narrow, sinuate ( Fig. 464 ).

Variation. Length 2.0– 2.5 mm, width 1.6–2.0 mm.

Type material. Holotype male; Peru, Satipo , VII-VIII 1942, Paprzycki ( USNM) . Paratypes; 300, same data as holotype except some dates II, X, XI ( USNM) .

Other specimens. Peru. Approximately 500, same data as holotype ; Dept. Ayacucho, La Mar, Santa Rosa , 640m, 8-15-IX-1976, Robert Gordon ; Tingo Maria, Dec-Feb 1949-50, H. A. Allard ; 1, Upper R. Pachitea, July 21, ‘20 ; Vic. Sani Beni , 840m., a.s.l., 12-1-1935, F. Woytkowski. ( CAS) ( USNM) .

Remarks. A huge series of this species from Satipo, Peru, exists in the USNM collection. The number under “Other specimens” is listed as approximate because, in addition to mounted material, there are two large gelatin capsules of unmounted, uncounted specimens.

Etymology. The specific epithet refers to the type locality.
