Diagnosis. The brown X-like marking on the basal ½ of the elytron disc will distinguish the members of this species from congeners.
Description. Size. Length 7.5 mm; width 1.7 mm. Form. As in Fig. 94 View Figures 94–97 . Color. Cranium, thorax, and abdomen castaneous; antenna testaceous; elytra bicolorous, mostly flavotestaceous, basal half with brown X-like marking, each elytron with slender brown streak on side, distal ½ of elytron disc with brown angular marking that narrowly extends towards elytral base along sutural margin; legs flavotestaceous. Head. Cranium finely punctate, frons slightly wider than length of antennal pedicel; EW/FW 37/10. Thorax. Pronotum finely punctate, with 2 tumescences, concave at middle; PW/PL 70/105; elytra, asetiferous punctures concentrated in middle of disc, one stria proximal to sutural margin; EL/EW 350/50. Abdomen. Aedeagus ( Fig. 44 View Figures 44–49 ), phallobasic lobes short; edge of phallic plates minutely serrate; phallobasic apodeme abbreviated.
Variation. Size. Length 6.5–11.0 mm; width 1.8–2.0 mm. The brown markings on the elytron disc vary in prominence.
Natural history. Specimens were collected in Brazil during November and December, some at 800 m.
Distribution (For a map Fig. 73 View Figure 73 ). This species is known from Brazil.
Etymology. The specific epithet, chiasta , is a Greek name derived from chiasmos (= crosswise). I refer to the X-like marking in the basal ½ of the elytral disc.
