36. Serratitibia bonnie Gordon and Canepari , new species

Description. Male holotype. Length 3.5 mm, width 2.7 mm; body oval, convex. Dorsal surface shiny, lacking alutaceous sculpture. Color yellow; pronotum with small, narrow, black basomedial macula extended 1/4 distance to anterior pronotal margin, apex of macula deeply emarginate with yellow; elytron black with 5 yellow spots arranged in rows of 2 each with apical spot, mediolateral spot irregularly transversely rectangular, projected inward, apical spot transversely oval, apical border rounded ( Fig. 246 ); venter of head, prosternum, meso–, metaventrites dark brown; abdomen yellowish 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 6 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 with 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 rounded, surface densely, finely punctured. Genitalia with basal lobe slender, 3/4 as long as paramere, sides slightly convergent, apex obliquely truncate; paramere Unm type, wide, widened apically, apex truncate, slightly rounded ( Fig. 247, 248 ); sipho robust, strongly curved in basal 3/4, basal capsule with inner arm long, wide at base, tapered to rounded apex, outer arm shorter than inner arm, wide, with accessory piece, basal border broadly, deeply emarginate ( Fig. 249, 250 ).

Female. Similar to male except pronotum with basomedial macula large, extended 3/4 distance to anterior pronotal margin, apex indented with yellow, elytron with small humeral spot. Genitalia with spermathecal capsule long, curved medially, widened from base to apex; bursal cap round, with 3 arms, inner arm faint, apical strut long, triangularly widened before apex in lateral view ( Fig. 251 ).

Variation. Length 3.4–3.6 mm. Female with or without humeral spot.

Type material. Holotype male; Peru, Loreto, Picuruyacu, 150 m., 9/ 13-VIII-2008, Leg. R. Westerduijn. Altered forest ( MKRB) . Paratypes; 4, same data as holotype ( GGC) ( MKRB) ( UNMSM) ( UNSAC) .

Remarks. This species is very similar to S. donna , but S. bonnie has the basomedial pronotal macula with straight apical margin, and male genitalia with the parameral apex broad, mostly truncate. Both species have median setal tufts on both the metaventrite and basal abdominal ventrite.
