89. Serratitibia andrea Gordon and Canepari , new species

Description. Male holotype. Length 3.0 mm, width 2.5 mm; body oval, convex. Dorsal surface shiny, lacking alutaceous sculpture except pronotum very slightly alutaceous, shiny. Color yellow; pronotum with large, black basomedial macula extended about 4/5 distance to anterior pronotal margin, apex of macula curved; elytron yellow with 3 black spots, spot on humeral callus very small, discal spot large, broadly oval, apical spot small, transversely oval ( Fig. 498 ); venter of head, prosternum, meso–, metaventrites reddish brown; abdomen reddish yellow. Head punctures small, separated by less than diameter, 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 1–3 times diameter; metaventral punctures much larger than on elytra, separated by 1–3 times diameter medially, larger laterally. Clypeus weakly emarginate apically, lateral angle abruptly rounded. Eye canthus about 5 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 rounded, basal margin with trace of bordering line. Epipleuron narrow, deeply grooved, deeply emarginate for reception of femoral apices. Protibia with outer margin weakly flanged, flange smooth, without serrations, 1/3 as wide as remainder of protibia, sponda extended beyond protibial border. Carinae on prosternal process indistinct, widely separated at apex, convergent, not joined apically, ended at about basal 1/3 of prosternum, not connected to base. Metaventrite without median setal tuft. Basal abdominal ventrite with median setal tuft. Abdomen with small primary pores extended under apical 1/4 of ventrite 4; postcoxal line on basal abdominal ventrite angled to posterior ventrite margin, flattened 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 short, wide, apically truncate, median tubercle, apical margin shallowly emarginate, angle on each side of emargination bearing tuft of setae. Apical tergite short, narrow, apex broadly, weakly rounded, surface densely, finely punctured. Genitalia with basal lobe as long as paramere, wide, sides weakly convergent, apex obliquely rounded; paramere Unm type, wide, slightly widened apically, apex rounded ( Fig. 499, 500 ); sipho robust, strongly curved in basal 2/3, basal capsule with inner arm short, slender, apex obliquely truncate, outer arm longer than inner arm, slen- der, with accessory piece, basal border broadly, deeply emarginate ( Fig. 501, 502 ).

Female. Similar to male except head reddish yellow. Genitalia with spermathecal capsule slender, curved medially, cornu slightly enlarged; bursal cap broadly rounded, apical strut slender, straight, extended from round, sclerotized base ( Fig. 503 ).

Variation. Length 3.0– 3.3 mm, width 2.5–2.7 mm. Frons of head may have dark brown, median spot, humeral spot on elytron may be light brown, indistinct.

Type material. Holotype male; (Brazil), Pae Mathias, S. Paulo, 2.I.1960, Halik 15489, BRASIL Halik 1966 Collection ( USNM) . Paratypes; 6, 2, Brasilien , Nova Teutonia, 27 o 11’B. 52 o 23’L, Fritz Plaumann, 11.8.1939 ( DZUP) ; 1, Brasilien, Nova Teutonia, 27 o 11’B. 52 o 23’L, Fritz Plaumann, Korschefsky collection 2952 ( USNM) ; 2.

Remarks. This large species with a unique elytral color pattern is immediately recognizable. It is surprising that a species with this outstanding appearance was not noted by early authors such as Mulsant and Crotch.
