38. Serratitibia heather Gordon and Canepari , new species

Description. Male holotype. Length 2.5 mm, width 2.0 mm; body oval, convex. Dorsal surface shiny, lacking alutaceous sculpture. Color yellow; pronotum with small, black basomedial macula extended 2/3 distance to anterior pronotal margin, apex of macula very slightly emarginate with yellow; elytron black with 5 large yellow spots arranged in rows of 2 each with apical spot, mediolateral spot irregularly oval, apical spot transversely oval ( Fig. 258 ); median 1/3 of prosternum, meso–, metaventrites dark brown; abdomen yellow except median area of ventrites 1–3 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 larger than 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 narrower than remainder of protibia, outer margin weakly arcuate, with about 6 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 1/6 of prosternum, connected to base by short stem. Metaventrite without setal tuft. Basal abdominal ventrite with indistinct, 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; 5 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 weakly rounded, surface densely, finely punctured. Genitalia with basal lobe slender, 3/4 as long as paramere, sides convergent, apex obliquely rounded; paramere Unm type, slender, slightly widened apically, apex truncate ( Fig. 259, 260 ); sipho robust, strongly curved in basal 2/3, basal capsule with inner arm short, slender, apex obliquely truncate, outer arm 2 times as long as inner arm, slender, with accessory piece, basal border broadly, deeply emarginate ( Fig. 261, 262 ).

Female. Similar to male except pronotum with basomedial macula large, extended nearly to anterior pronotal margin, apex rounded, elytron without humeral spot. Genitalia with spermathecal capsule long, curved medially, cornu enlarged; bursal cap rounded, with 3 arms, inner arm faint, apical strut short, triangularly widened in apical 1/ 2 in lateral view ( Fig. 263 ).

Variation. Length 2.4–2.7 mm, width 1.8–2.0 mm. Basomedial pronotal macula in male may have anterior margin distinctly indented with yellow, mediolateral spot on elytron varies from oval to irregularly, transversely oval.

Type material. Holotype male; Peru, Loreto, Puerto Almendera , 100 m, 14-IX-2006, leg. R. Westerduijn, secondary forest arboretum ( MKRB) . Paratypes; 4, 2, same data as holotype ( GGC) ; 2, same data as holotype except date 15-IX-2006 ( MDC) ( UNSAC) .

Other specimens. 4. Peru, Loreto, Padre Cocha, 150 m., 20-II-2006, Westerduijn, Woodland. ( GGC).

Remarks. The sixth abdominal ventrite with a median tubercle and protibial flange narrower than remainder of protibia help to distinguish S. heather from similar Peruvian species such as S. julie .
