37. Serratitibia julie Gordon and Canepari , new species

Description. Male holotype. Length 2.7 mm, width 2.3 mm; body oval, convex. Dorsal surface shiny, lacking alutaceous sculpture. Color yellow; pronotum with large, wide, black basomedial macula extended 2/3 distance to anterior pronotal margin, apex of macula weakly emarginate with yellow; elytron black with 5 large yellow spots arranged in rows of 2 each with apical spot, mediolateral spot oval, apical spot transverse, apical border truncate ( Fig. 252 ); venter of head, prosternum, meso–, metaventrites dark brown; abdomen dark brown. Head punctures small, separated by diameter or less, each puncture as large as 2 eye facets; pronotal punctures as large as head punctures, separated by diameter or less; elytral punctures as large as on pronotum, separated by less than 2 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 4 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 without trace of bordering line. Epipleuron narrow, deeply grooved, deeply emarginate for reception of femoral apices. Protibial flange wider than remainder of protibia, outer margin strongly arcuate, with about 8 small teeth throughout, sponda extended beyond protibial border. Carinae on prosternal process narrowly separated at apex, convergent, joined at basal 1/4 of prosternum, connected to base by short stem. Metaventrite without setal tuft. Basal abdominal ventrite with 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, without median tubercle, apical margin shallowly emarginate, angle on each side of emargination bearing tuft of setae. Apical tergite short, narrow, apex weakly emarginate, surface densely, finely punctured. Genitalia with basal lobe slender, 3/4 as long as paramere, sides slightly convergent, apex obliquely rounded; paramere Unm type, wide, widened apically, apex truncate ( Fig. 253, 254 ); sipho robust, strongly curved in basal 1/2, basal capsule with inner arm long, slender, apex obliquely, irregularly truncate, outer arm slightly longer than inner arm, slender, with accessory piece, basal border broadly, deeply emarginate ( Fig. 255, 256 ).

Female. Similar to male except pronotum with basomedial macula large, extended nearly to anterior pronotal margin, apex slightly indented with yellow, elytron without humeral spot. Genitalia with spermathecal capsule long, curved medially, cornu enlarged; bursal cap broadly triangular, with 3 arms, inner arm faint, apical strut short, widened in apical / 12 in lateral view ( Fig. 257 ).

Variation. Length 2.5–2.8 mm, width 2.1–2.3 mm.

Type material. Holotype male; Peru, Cuzco, San Pedro Manu 1500 m., 16/ 18-VI-2006, Leg. R. Westerduijn, Montane evergreen forest ( UNSAC) . Paratypes; 3, same data as holotype ( GGC) ( MKRB) ( UNMSM) .

Remarks. A combination of large elytral spots, male with setal tuft on the basal abdominal ventrite, and male pronotum with basomedial macula distinctly emarginate with yellow at apex will aid in distinguishing S. julie from other Peruvian species with apically truncate genitalic parameres.
