79. Serratitibia beverly Gordon and Canepari , new species

Description. Male holotype. Length 2.4 mm, width 1.8 mm; body round, slightly elongate, convex. Dorsal surface shiny, lacking alutaceous sculpture. Color yellow; pronotum with black, mediobasal macula extended 1/2 distance to apical pronotal margin, apex of macula triangularly emarginate with yellow, weak emargination present on each side of middle; elytron black with 5 small, yellow spots, spots arranged in transverse rows of two each plus one at apex, apical spot transversely oval ( Fig. 443 ); mesoventrite pale reddish brown, metaventrite dark reddish brown; abdomen yellow. Head punctures small, separated by less than diameter, each puncture as large as 1–2 eye facets; pronotal punctures as large as on head, separated by diameter or less; elytral punctures as large as pronotal punctures, separated by less than 2 times diameter. Clypeus truncate apically, lateral angle abruptly rounded. Eye canthus about 6 eye facets long, angled forward, apically rounded, yellow. Pronotum narrowed from base to apex, basal angle slightly rounded, anterior angle abruptly rounded, lateral margin weakly rounded, basal margin without bordering line. Epipleuron narrow, grooved, deeply emarginate for reception of femoral apices. Protibial flange as wide as remainder of protibia, outer margin arcuate with about 8 small teeth throughout, teeth large medially, sponda extended beyond protibial border. Carinae on prosternal process narrowly separated at apex, slightly convergent, joined at basal 1/3 of prosternum, not connected to 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, flattened 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, with small tubercle bearing tuft of setae on each side of median depression; 6th ventrite short, narrow, weakly depressed in apical 1/2, depression glabrous, without median tubercle, apical margin shallowly emarginate, angle on each side of emargination rounded, bearing small tuft of dense setae. Apical tergite short, narrow, apex slightly rounded, surface densely, finely punctured. Genitalia with basal lobe 2/3 as long as paramere, sides slightly convergent, apex obliquely rounded; paramere Unm type, widened apically, apex rounded ( Fig. 444, 445 ); sipho curved in basal 2/3, basal capsule with inner arm slender, narrowed medially, apex truncate, outer arm slightly wider than inner arm, longer than inner arm, with accessory piece, basal border deeply emarginate ( Fig. 446 ).

Female. Similar to male except head reddish yellow, basomedial macula on pronotum large, extended nearly to anterior pronotal margin, apex barely perceptibly emarginate with yellow, elytron without humeral spot. Genitalia with spermathecal capsule long, slender, curved medially, cornu enlarged; bursal cap rounded, with 3 arms, inner arm faint, apical strut long, apex spatulate in lateral view ( Fig.447 ).

Variation. Length 2.2–2.4 mm, width 1.7–1.8 mm.

Type material. Holotype male; Peru, Puerto Almendra , 100 m, 14-IX-2006, leg. R. Westerduijn, secondary forest Arboretum ( MKRB) . Paratypes; 3, 1, same data as holotype ( GGC) ; 1, same data as holotype except 15-IV-2006, understory of altered forest, arboretum “El Huayo.” ( UNSAC) ; 1, Peru, Padre Cocha , 150 m, 20-II-2006, Leg. R. Westerduijn, Woodland ( GGC) .

Remarks. This little species is similar to several others having the same basic color pattern, but the males with bright yellow prosternum and legs, and doubly indented pronotal macula are reasonably distinctive.
