Diagnosis.

Overall coloration (Fig. 4 A, B ) pale-yellow. Crown, face and pronotum anterior third (Fig. 4 A ) with distinct brownish areas. Forewings (Fig. 4 A, B ) brownish, with paler veins. Abdomen (Fig. 4 C ) yellow, with darkened areas. Female abdominal sternite VII (Fig. 4 C ) wider than long, with lateral margins slightly rounded posteriorly and with a slightly rounded median lobe.

Description.

Coloration: Overall coloration (Fig. 4 A, B ) pale-yellow. Crown (Fig. 4 A ), in dorsal view, with distinct brownish areas. Face (Fig. 4 C ) with a brownish band between eyes and frontogenal suture, muscular impressions yellow, often a pale longitudinal band medially. Pronotum (Fig. 4 A ), in dorsal view, anterior third with distinct darker marks and a darkened arched or semi-arched maculae, posterior third smoky brown. Mesonotum (Fig. 4 A ), in dorsal view, yellow, usually with a pair of darkened triangular maculae laterally, a pair of darkened rounded maculae medially. Forewing (Fig. 4 A, B ) brownish, with veins distinctly paler. Abdomen (Fig. 4 C ), in ventral view, yellowish ventrally with darkened areas. Legs (Fig. 4 B, C ) yellowish, metasternum slightly darker. — Male: Unknown. — Female genitalia: Sternite VII (Fig. 4 C ), in ventral view, wider than long; lateral margins subparallel, slightly rounded posteriorly; posterior margin with a slight and rounded median lobe.

Material examined.

Holotype: BOLIVIA • ♀; Puerto Suarez ; 150 m; J. Steinbach leg.; CMNH -IZ 724,504 ; CMNZ.

Remarks.

Cicadella callosa was described based on a female holotype analyzed herein, and a female paratype, both from Bolivia. In the original description, a male allotype was designed, from Bom Fin, probably misspelled from the municipality of Bonfim, in Salvador, Bahia State, Brazil. Young (1977) transferred Cicadella callosa to Ciminius , reporting the close assemblance of the female abdominal sternites VII of C. callosa holotype and his illustration of C. platensis . The overall coloration of C. callosa holotype is similar to any other Ciminius representant, except C. dissidens sp. nov. and the black form females of C. albolineatus . Compared to the original description, the male allotype from Bahia overall coloration is similar to any other pale-yellow male found in the genus. The male genitalia capsule of C. callosa allotype was illustrated only externally in ventral view, originally described without any useful features that could be used for its identification. After the original work, in 1926, no other representative of this species was reported.
