44. Serratitibia katherine Gordon and Canepari , new species

Description. Male holotype. Length 3.0 mm, width 2.5 mm; body oval, convex. Dorsal surface shiny, pronotum and elytra with faint alutaceous sculpture. Color yellow; pronotum yellow except black basomedial macula short, outer angle with oblique anterior projection extended to apical 2/3 of pronotum, apex of projection curved inward and hooked posteriorly at apex; elytron with suture narrowly black, with 4 small, black spots, humeral spot irregularly, obliquely elongate, from base of elytron posteriorly across humeral callus, discal spot irregularly triangular, mediolateral spot on outer margin of elytron obliquely elongate, spot on apical declivity irregularly, obliquely rectangular ( Fig. 291 ); venter of head, prosternum reddish yellow, meso–, metaventrites dark reddish brown; abdomen yellow except median 1/ 3 of ventrites 1–3 yellowish brown. Head punctures small, separated by less than diameter, each puncture as large as 1 eye facet; pronotal punctures as large as head punctures, separated by diameter or less; elytral punctures smaller than on pronotum, separated by 1–2 times diameter; metaventral punctures larger than on elytra, separated by less than 2 times diameter medially, larger laterally. Clypeus truncate 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, weakly grooved, deeply emarginate for reception of femoral apices. Protibial flange as wide as remainder of protibia, outer margin arcuate, with about 8 teeth throughout, teeth large medially, smaller in basal and apical 1/3, sponda extended beyond protibial border. Carinae on prosternal process narrowly separated at apex, weakly convergent, 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 small, extended under apical 1/4 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 weakly emarginate, surface densely, finely punctured. Genitalia with basal lobe 3/4 length of paramere, sides convergent, apex obliquely truncate, paramere Unm type, wide, widened apically, apex truncate ( Fig. 292, 293 ); sipho robust, strongly curved in basal 2/3, basal capsule with inner arm short, slender, narrowed to apex, apex obliquely truncate, outer arm longer than inner arm, wide, with accessory piece, basal border broadly, shallowly emarginate ( Fig. 294 ).

Female. Unknown.

Variation. Length 2.8–3.0 mm, width 2.4–2.5 mm. Pronotal and elytral markings are reduced in paratype, pronotum has basomedial macula not connected to small, triangular, discal spots medially, spots on elytron small, discal spot barely evident. The paratype has the same basic elytral pattern as the holotype, but all dark markings are severely reduced in size, although in the same places.

Type material. Holotype male; Peru, N. Peru, 2100m, Rio Chotano , VI-23-1956, W. Weyrauch 7015 ( USNM) . Paratype; 1, Peru, Cusco, 80 km North of Calca , 7-Mar-1978, Univ. Maryland - SEL: SMF Expedition ( USNM) .

Remarks. The dorsal color pattern is diagnostic for this species, although somewhat similar to that of S. doris .
