39. Serratitibia paprzycki Gordon and Canepari , new species

Description. Male holotype. Length 2.7 mm, width 2.2 mm; body oval, convex. Dorsal surface shiny, lacking alutaceous sculpture. Color yellow; pronotum with short, narrow, black basomedial macula extended about 1/5 distance to anterior pronotal margin, apex of macula broadly emarginate with yellow, with short, anteriorly projecting spur present medially, small, dark yellow, narrowly triangular macula on each side of disc medially; elytron black with 5 large yellow spots arranged in rows of 2 each with apical spot, mediolateral spot irregularly transverse, apical spot transversely rectangular with broadly emarginate apical border ( Fig. 264 ); median 1/3 of prosternum, meso–, metaventrites reddish brown; abdomen yellow except median area of ventrite 1 dark brown, median area of ventrites 2–4 yellowish brown. 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 larger than on pronotum, separated by 1–3 times diameter; metaventral punctures larger than on elytra, separated by less than diameter medially, larger laterally. Clypeus weakly emarginate apically, lateral angle abruptly rounded. Eye canthus about 5 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 rounded, basal margin with trace of bordering line. Epipleuron narrow, deeply grooved, deeply emarginate for reception of femoral apices. Protibial flange wider than remainder of protibia, outer margin weakly arcuate, with about 8 small teeth throughout, median 2 teeth slightly larger, sponda extended beyond protibial border. Carinae on prosternal process narrowly separated at apex, parallel, joined at basal 1/4 of prosternum, connected to base by short stem. Metaventrite without setal tuft. Basal abdominal ventrite without median setal tuft. Abdomen with primary pores laterally between ventrites 4–5 large, extended under apical 1/3 of ventrite 4; postcoxal line on basal abdominal ventrite angled to posterior ventrite margin, rounded along margin, apex extended forward. Abdominal ventrites 1–4 with short, sparse pubescence, punctures on basal 3 ventrites large medially, separated by diameter or less, becoming smaller and dense laterally, ventrites 3–5 densely punctured throughout; 5th ventrite depressed medially in apical 1/2, apical border weakly emarginate medially, lateral angle of emargination with small tubercle bearing tuft of dense setae; 6th ventrite narrow, deeply depressed medially, depression glabrous, with median tubercle, apical margin shallowly emarginate, angle on each side of emargination bearing tuft of setae. Apical tergite short, narrow, apex truncate, surface densely, finely punctured. Genitalia with basal lobe slender, 5/6 as long as paramere, sides weakly convergent, apex obliquely rounded; paramere Unm type, slender, slightly widened apically, apex truncate ( Fig. 265, 266 ); sipho robust, strongly curved in basal 2/3, basal capsule with inner arm short, wide, apex irregularly truncate, outer arm 2 times as long as inner arm, wide, with accessory piece, basal border abruptly, deeply emarginate ( Fig. 267, 268 ).

Female. Similar to male except pronotum with basomedial macula large, extended nearly to anterior pronotal margin, apex rounded, elytron with humeral spot. Genitalia with spermathecal capsule long, curved medially, cornu enlarged; bursal cap rounded, with 3 arms, inner arm faint, apical strut short, broadly spatulate in apical 3/ 4 in lateral view ( Fig. 269 ).

Variation. Length 2.4–2.7 mm, width 1.8–1.9 mm. Dark yellow pronotal maculae vary in color from dark yellow to dark brown. Specimens listed as “other specimens” differ from the types by having the black elytral areas brown instead of black.

Type material. Holotype male; Peru, Satipo, XI, 1942, Paprzycki ( USNM) . Paratypes; 73, 2, same data as holotype ( USNM) ; 71, same data as holotype except additional dates X-1942, 1943, VII-1944, VIII- 1944, IX-1944 ( USNM) .

Other specimens. 3. Peru. Vilcanota, ex. coll. J. Weise, one specimen with additional label “ Cleothera lividipes Muls. ” ( ZMHB).

Remarks. This is a highly distinctive species, distinguished by the mostly pale male pronotum, tuberculate male 6th abdominal ventrite, and female with a humeral spot.

In the early 1940’s a collector Paprzycki amassed a large number of species from Satipo, Peru. Among these specimens were large series of S. donna , S. satipoensis , and S. papyrzycki . All are distinctly differentiated from each other, and all belong in different sections or groups of Serratitibia .

Etymology. This species is named for the collector in recognition of his efforts in obtaining hundreds of Peruvian Coccinellidae .
