Dorynota (Dorynota) parallela Blanchard, 1846 ( Figs. 28–29 , 46 )

Dorynota parallela Blanchard, 1846: 212 (type locality: ‘ Guarayos ( Bolivia)’).

Type Material Examined. Paralectotype (designated by Borowiec 1999), pinned: ‘ MUSEUM PARIS ∣ BOLIVIE ∣ (CHIQUITOS) ∣ D`Orbigny 1834 [w, p, cb, bb] ∥ 7316 ∣ 34 [circle label] ∥ PARALECTOTYPE ∣ des. L. Borowiec [r, p, cb, bb]’ ( MNHN) .

Additional Material Examined (54). ARGENTINA: Misiones: without additional locality data, V.1955, Dirings lgt. (1 female, MZUSP) ; BRAZIL: Bahia: without additional locality data, G. Bondar lgt. (13 spec. MNRJ, 3 specimens, USNM) ; Pará: Santarém (Santarenzinho, Rio Tapajós ), II.1964, Dirings lgt. (26 specimens, MZUSP) ; São Paulo: without additional locality data (1 specimen, DZUP) ; Vale do Anhangabaú , XI.1924, R. Spitz lgt. (2 specimens, MNRJ) ; Rio Claro , 13.XI.1980, Alejo Mesa lgt. (1 specimen, MZUSP) ; Santa Catarina: Corupá , XI.1944, J. Guerín lgt. (1 specimen, USNM) ; BOLIVIA: Beni: Reyes , 1–20.XII.1956, L. Peña lgt. (1 specimen, MNRJ) ; Santa Cruz: Chiquitos, Santiago , 730m, XI.2008, W. D. Edmonds & T. Vidaurre (4 specimens, TAMU) .

Diagnosis. Dorynota parallela can be easily distinguished from other species as having densely punctate intervals of the elytra and rounded humeral angles. Dorynota pugionata and D. hastifera have acute humeral angles and more sparsely and more finely punctate intervals. Dorynota aculeata differs in that it has very finely and sparsely punctate intervals and humeral angles that are not expanded laterally.

Remarks. The species was considered until now as being described in 1837. However, d’ Orbigny’ s voyage was published in many separate issues, and the volume containing a greater part of the beetles (including the subfamily Cassidinae ) was published as late as 1846 (Sherborn and Woodward 1901), thus the year of publication must be revised to reflect this.

Boheman (1854) redescribed the species, with further details of body color and elytral and pronotal shape and punctuation, and transferred it to the genus Batonota Hope, 1840 . Monrós and Viana (1949) revised the Argentine species of Dorynotini and transferred Batonota parallela (Blanchard) to a newly formed genus, Paranota Monrós and Viana, 1949 . Recently, Simões (2014) revised the genus Paranota and transferred P. parallela back to Dorynota (s. str.) on the basis of the structure of the anterior margin of the pronotum, scutellum, tarsal claws, and male terminalia.

Spaeth (1914) recorded the species from Ecuador, and Borowiec (1996) reported it from French Guiana. However, both records must be considered as erroneous. The first one was published by Spaeth (1914) in the Coleopterorum Catalogus where he cited Ecuador as part the species’ distribution and since then it was followed. It is questionable whether Spaeth had seen some specimen(s) from Ecuador (there are none in his collection), or perhaps the record is the result of an error. Borowiec (1998) considered the record an error as well. Borowiec (1996) recorded the species as new to French Guiana, based on old specimens from Bas Maroni. However, these specimens were most likely mislabeled, as pointed out later by Borowiec and Moragues (2005).

Distribution. Brazil (Goiás, Mato Grosso, Minas Gerais, Rio de Janeiro); Bolivia (Santa Cruz); Peru (Vilcanota); Paraguay (Asunción, Concepción) (Borowiec and Świętojańska 2014). New country record for Argentina (Misiones), four new state records for Brazil (Pará, Bahia, São Paulo, Santa Catarina), and new department record for Bolivia (Beni) ( Fig. 46 ).
