10. Serratitibia traili (Brèthes) , new combination

Cleothera traili Brèthes, 1925b: 10 .

Hyperaspis traili: Korschefsky 1931: 197 ; Blackwelder 1945: 448.

Description. Male holotype. Length 2.5 mm, width 2.1 mm; body rounded, slightly oval, convex. Dorsal surface shiny, lacking alutaceous sculpture. Color yellow; pronotum with short, narrow, basomedial macula extended 1/5 distance to anterior pronotal margin, macula truncate on apical border, vague nebulous brown area present anterior to macula; elytron black with 4 small yellow spots, discal spot missing, scutellar, humeral, mediolateral, and apical spot present ( Fig. 108 ); venter of head, prosternum, meso–, metaventrites brown; abdomen yellow. Head punctures small, separated by less than diameter, each puncture as large as 1 eye facet; pronotal punctures equal in size to head punctures, separated by less than 2 times diameter; elytral punctures as large as on pronotum, separated by less than 3 times diameter; metaventral punctures larger than on elytra, separated by less than diameter medially, slightly larger laterally. Clypeus weakly emarginate 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 broadly rounded, anterior angle abruptly rounded, lateral margin slightly curved, basal margin without trace of bordering line. Epipleuron narrow, deeply grooved, deeply emarginate for reception of femoral apices. Protibial flange about as wide as remainder of protibia, outer margin weakly arcuate, with 4 prominent teeth medially, 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 without setal tuft. Basal abdominal ventrite without setal tuft. Abdomen with primary pores laterally between ventrites 4–5 small, extended under apical1/4 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, separated by less than 2 times diameter medially, 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 pronounced 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 abruptly pronounced, bearing tuft of setae. Apical tergite short, narrow, apex barely perceptibly emarginate medially, surface densely, finely punctured. Genitalia with basal lobe 3/4 length of paramere, sides convergent, apex obliquely rounded; paramere Unm type, wide, apex rounded ( Fig. 109, 110 ); sipho robust, curved in basal 1/2, basal capsule with inner arm long, wide, apex widened, obliquely truncate, outer arm wider and longer than inner arm, with accessory piece, basal border broadly, deeply emarginate ( Fig. 111, 112 ).

Female. Unknown.

Variation. Unknown.

Type locality. Brazil, “Amazons” (holotype).

Type depository. BMNH.

Geographical distribution. Brazil.

Specimens examined. 1. Brazil. The holotype male “Amazons., J. E. trail, 97-71, Cleothera traili .” ( BMNH).

Remarks. Very few Serratitibia species with yellow on black coloration lack a discal spot, thus rendering S. traili one of the few easily recognized species in the genus.
