Plateros curtebilineatus ( Pic, 1934 )


Plateros curtebilineatus ( Pic, 1934)  comb. et stat. nov.

Calleros brasiliensis  var. curtebilineatus Pic, 1934: 128  .

Type material. Holotype, female, BRAZIL “Bahia” without other data ( MNHNAbout MNHN).

Diagnosis: P. curtebilineatus  differs from P. brasiliensis Lucas, 1857  by the shape of genitalia, in having larger scutellum and by presenting uniform dark brown coloration in elytral apical ½.

Redescription: Body with ventral surface dark brown. Head dark brown with prominent eyes, eye diameter 1.1 x longer than interocular distance. Antennae subserrate, antennomere 4 as long as 5, about 1.6 x longer than 3. Mandibles stout, labial palpi short, maxillary palpi elongate, terminal palpomere 1.4 x longer than 2 and 2.5 x longer than palpomere 3. Pronotum subpentagonal, 1.1 x wider than long, widest at basal margin with posterior angles projected obliquely, basal margin bisinuate, discrete median longitudinal carina present at apical 1 / 6, longitudinal median line channeled in basal half. Pronotum dark brown along median portion with lateral sides yellow. Scutellum dark brown, subsquare, large, straight distally. Elytra yellow, dark brown in distal ½, each elytron with 9 costae, primary costae stronger, regular reticulate cells subsquare. Prosternum triangular, strongly transverse, mesosternum trapezoidal. Legs compressed, trochanters yellow, conical. Femora dark brown, with proximal half yellow, 1.1 x longer than tibiae, ¼ as long as trochanter. Female abdominal sternum 9 rounded apically, with shallow emargination distally. Female genitalia with long coxites, projected dorsally and medially to accommodate the proctiger, lateral sides convergent distally. Valvifers reduced, integrated to coxites. Proctiger well developed, styli small ( Fig. 7View FIGURE 1 – 12). Body length: 8 mm, humeral width: 1.9 mm.

Distribution: Brazil (Northeastern region, Bahia state)

Remark: Bocakova (2001) synonymized Calleros to Plateros  , so P. brasiliensis  validity is reinstated (cf. Pic, 1934), known to occur in Southeastern Brazil, São Paulo State. Examination of the holotype of Calleros brasiliensis  var. curtebilineatus Pic, 1934  from MNHNAbout MNHN showed that it is a member of Plateros  , forming a separate species from Plateros brasiliensis  . Therefore, Calleros brasiliensis  var. curtebilineatus Pic, 1934  is transferred to the genus Plateros  and Plateros curtebilineatus ( Pic, 1934)  comb. et stat. n. is proposed.
