Type material. Holotype, male, BRAZIL: Morretes-PR Brasil; (IAPAR); 17-24.ix.1984; C.I.I.F. (Luminosa). (DZUP).

Diagnosis: Eye diameter 1.5× longer than interocular distance. Maxillary palpomere 2 3.3× longer than 3. Pronotum 1.3× wider than long, median longitudinal carina in apical 1/3 with areola occupying mostly posterior 2/3, connected to the posterior margin by a very short carina. Elytra with yellow humeral region and median transversal band increasing in thickness towards marginal costae, with irregular dark brown spots in basal 1/2 and distal 1/3 (Fig. 6). Phallus slightly curved, apical projections with several thorns (Fig. 15a), parameres medially constricted in ventral view (Fig. 16), with rugose surface and several ventral and lateral thorns (Figs. 15c, 16).

Description: Maxillary palpomeres dark brown. Trochanters yellow, basal 1/4 of median femur yellow. Pronotum dark brown with lateral sides yellow and anterior margin light brown. Elytra with yellow humeral region and median transversal band increasing in thickness towards marginal costae, with irregular ellipsoidal dark brown spots in basal half and distal 1/3 (Fig. 6).

Eye diameter 1.5× longer than interocular distance. Antennomeres 3−5 are almost the same length. Maxillary palpomere 2 almost as long as 4 and 3.3× longer than 3. Pronotum 1.3× wider than long, median longitudinal carina bifurcating in anterior 1/3 forming areola mostly at posterior 2/3, connected to the posterior margin by a very short carina. Scutellum with posterior margin shallowly emarginated. Prosternum quite triangular, mesoventrite trapezoidal. Elytra 4.1× longer than humeral width, intercostal intervals with irregular cells. Hind femora 3.1× longer than trochanter length. Male genitalia with a short phallus, slightly curved from basal half in lateral view, with apical projections bearing several thorns and apex of phallus strongly ventrally-oriented (Figs. 15a, b); parameres elongate, almost as long as phallus, ventrally bent towards the apex in lateral view sinuose and medially slightly constricted in ventral view, presenting rugose surface, apically rounded with several ventral and lateral subapical thorns (Fig. 15c) and joined basally by a ring-like bridge, phallobase slightly asymmetric and about 3/4 as long as parameres length (Fig. 15–16). Body length: 5.8 mm, humeral width: 1.4 mm.
