Dorynota (Dorynota) pugionata ( Germar, 1824) ( Figs. 30–31 , 46 )

Cassida pugionata Germar, 1824: 537 (type locality: ‘Brasilia’).

Batonota Ballista Boheman, 1854: 157 (type locality: ‘Brasilia’); Spaeth, 1914: 66 (synonym).

Type Material Examined. Lectotype (designated by Borowiec 1999), pinned: ‘14261 [w, p, s] ∥ LECTOTYPE ∣ des. L. Borowiec [r, p, cb] ∥ pugionata / Boh.* / S. Joao d. R. Sello. [g, hw, cb, bb]’ ( ZMHB); five paralectotypes without labels but according to the register coming from the same series as the lectotype, pinned ( ZMHB). All specimens were provided with an additional label: ‘ LECTOTYPUS [or PARALECTOTYPUS] ∣ Cassida ∣ pugionata ∣ Germar, 1824 ∣ L. Borowiec des. [r, p, cb, bb]’. Batonota ballista : lectotype (designated by Borowiec (1999)), pinned: ‘ Brasil. [w, p, cb] ∥ M. Berl [w, p, cb] ∥ Type. [w, p, cb] ∥ Ballista Bhn. [w, hw, s, Boheman’ s hw] ∥ LECTOTYPE ∣ des. L. Borowiec [r, p, cb] ∥ NHRS-SRAH ∣ 000000105 [w, p, cb]’ ( SMNH).

Additional Material Examined (5). BRAZIL: Pará: Cachimbo, 1890, Ch. Pujol lgt. (1 specimen, MNHN) ; BOLIVIA: Santa Cruz: Chiquitos, 1834, d’ Orbigny lgt. (2 specimens, MNHN) ; PARAGUAY: Asunción: without additional locality data (1 specimen, ZMHB) ; Paraguarí: ‘Paraguari’ (1 specimen, MMUE) .

Diagnosis. Dorynota pugionata is characterized by the following combination of characters: elytral intervals punctate; humeral angles acuminate; and elytra smooth, without ribs. Dorynota aculeata and D. parallela differ in their rounded humeral angles and the elytra with at least partly elevated intervals. The most similar species is D. hastifera , which differs by its less coarsely punctate intervals, a much narrower explanate margin of the elytra, and a dorsum which is mostly pale, with only the humeral carina being black.

Remarks. Boheman (1854) described B. ballista from an unknown number of specimens. However, he mentioned a length span and two depositories: ‘Mus. Reg. Holm. A Dom. Germar ad conferendum etiam misa’. Borowiec (1999) designated the lectotype from a specimen Boheman obtained from Germar and a paralectotype from a second specimen, originally from Stål. In our opinion, the second specimen is not part of the type series, since Boheman did not mention Stål among depositories nor was Stål mentioned as a collector/ depository in any of the species described in the Monographia Cassididarum. The specimen was most likely collected by J. W. Stål in southern Brazil and was certainly received after publishing the description. Therefore, we remove the specimen from the type series.

The MMUE specimen from Paraguay is quite likely the one published by Spaeth (1923) as a first record for this country, but without specified locality data.

Distribution. Argentina (Misiones), Brazil (Bahia, Espírito Santo, Goiás, Mato Grosso, Minas Gerais, Paraná, Rio Grande do Sul, Rio de Janeiro, São Paulo, Santa Catarina); Paraguay (Concepción, Presidente Hayes) (Borowiec and Świętojańska 2014). New country record for Bolivia, new state record in Brazil (Pará), and two new province records in Paraguay (Asunción, Paraguarí) ( Fig. 46 ).
