description: Plateros plaumanni nom. n.
pro Sculptocalleros discithorax Pic, 1949 nec Ditoneces discithorax Pic, 1926 Sculptocalleros discithorax Pic, 1949: 5 — syn.n.
Type material. Holotype, male, BRAZIL “Rio Gr. do Sul, coll. Rich.Hicker” without other data (MNHN). Other material: male, BRAZIL, “ 7-xi-1949, Nova Teutonia, 27°11’B 52°23’L, 300bis 500m, Fritz Plaumann [leg.]” (MZSP).
Diagnosis: P. plaumanni differs from other Plateros by presenting dark pronotum almost rectangular with circular yellow spot at the center and by the shape of genitalia.
Redescription: Body with ventral surface dark brown. Head dark brown, eyes small, interocular distance 1.5x longer than eye diameter. Antennae subserrate, antennomere 4 as long as 5, 1.2x longer than antennomere 3. Mandibles stout, arcuate, labial palpi short, terminal palpomere securiform, maxillary palpi elongate, palpomere 4 securiform, as long as wide, 2x longer than palpomere 3. Pronotum almost rectangular, 1.25 larger than long, posterior angles projected laterally, presenting carina at apical ½ followed by a median channel, basal margin slightly bisinuate. Pronotum dark brown with yellow spot at center. Scutellum dark brown with shallow median emargination apically. Elytra dark brown, with 9 costa, primary costae strong, secondary costae hardly visible, with irregular reticulate cells. Prosternum and mesosternum trapezoidal. Legs compressed, dark brown, femur as long as tibia, ½ as long as trochanter. Abdominal sternum 8 with median emargination distally, abdominal sternum 9 elongate, rounded distally, pointed apically. Phallus broad at basal ¼ in lateral view, slightly curved dorsally at apex, broader apically in ventral view, pointed distally with spine-like projection proximally. Phallobase quite asymmetrical, longer than large, with lateral projections pointed at apical ½ (Fig. 3). Body length: 6.1 mm, humeral width: 1.5 mm.
Distribution: Brazil (Southern region, Santa Catarina and Rio Grande do Sul States).
Etymology: species name after Fritz Plaumann, a great entomologist who lived in Southern Brazil and contributed much to science. Moreover, he collected many individuals of this species.
Remark: Bocakova (2001) synonymized many genera with Plateros, but she had not found the type of Sculptocalleros in Pic’s collection, and therefore, Sculptocalleros remained valid. Based mainly on male genitalia, monotypic Sculptocalleros Pic, 1949 is now considered as a junior synonym of Plateros Bourgeois, 1879. Moreover, Sculptocalleros discithorax Pic, 1949 (now in Plateros) became a junior secondary homonym of preoccupied Plateros discithorax (Pic, 1926), originally described in Ditoneces Waterhouse, 1879. Therefore, a new replacement name Plateros plaumanni nom.n. for Sculptocalleros discithorax Pic, 1949 is proposed.
