Abstract
The taxonomic identity of the butterfly Heliconius melpomene f. pyritosa var. fumigata Zikán, 1937 (Nymphalidae: Heliconiinae) is discussed based on the discovery of the specimen based on which this name was assigned. The specimen is not a variation of Eueides tales surdus Stichel, 1903, as previously stated, but is in fact a variation of H. melpomene f. pyritosa, which is a synonym of Heliconius erato amalfreda Riffarth, 1901.
Eueides; Heliconiini; Heliconius erato
In 1937, J.F. Zikán described seven new Heliconiini forms from Brazil and Peru, including
Heliconius melpomene f. pyritosa var.
fumigata Zikán, 1937, based on a single specimen from Mr. Ferdinand
Dissmann's collection ( Zikán, 1937Zikán, J.F., 1937. Neue Nymphaliden-Arten und -Formen aus Brasilien.
Entomol. Rundsch. 54, 328-331.). Subsequently,
Mielke and Casagrande (1987)Mielke, O.H.H., Casagrande, M.M., 1987. Sobre os tipos de Lepidoptera
deposita- dos em museus brasileiros. XI. Nymphalidae (Nymphalinae) descritos por José
Francisco Zikán. Rev. Bras. Entomol. 31, 399-403., in an effort to
locate all lepidopteran types deposited in Brazilian museums, found what they believed to
be the individual based on which H. melpomene f. pyritosa
var. fumigata had been described, in the Zikán collection (Fundação e
Instituto Oswaldo Cruz, Rio de Janeiro). This specimen, illustrated by Mielke and Casagrande (1987)Mielke, O.H.H., Casagrande, M.M., 1987. Sobre os tipos de Lepidoptera

, was identified as Eueides tales
surdus Stichel, 1903 by Lamas (2004)Mielke, O.H.H., Casagrande, M.M., 1987. Sobre os tipos de Lepidoptera
deposita- dos em museus brasileiros. XI. Nymphalidae (Nymphalinae) descritos por José
Francisco Zikán. Rev. Bras. Entomol. 31, 399-403.. In
2011, the F. Dissmann collection was donated to the Campinas State University (Unicamp).
The collection exceeds 2500 butterfly specimens that come from the all over the world, and
includes 11 alleged type specimens, among them six specimens of Heliconius
Kluk, 1780. One of these individuals is clearly labeled as the "holotype" of
Heliconius melpomene f. pyritosa var.
fumigata ( Fig. 1). The
collection also includes the two "cotypes" of Heliconius melpomene f.
pyritosa Zikán, 1937 mentioned by Zikán in the same publication. The
specimen here figured as H. melpomene f.
pyritosa var. fumigata ( Fig. 1) clearly fits the description provided by Zikán (1937)Zikán, J.F., 1937. Neue Nymphaliden-Arten und -Formen aus Brasilien.
Entomol. Rundsch. 54, 328-331., including the "sooty" nature of the yellow markings in
the forewing, not present in the specimen figured by Mielke
and Casagrande (1987)Mielke, O.H.H., Casagrande, M.M., 1987. Sobre os tipos de Lepidoptera
deposita- dos em museus brasileiros. XI. Nymphalidae (Nymphalinae) descritos por José
Francisco Zikán. Rev. Bras. Entomol. 31, 399-403.. In addition, the double series of submarginal white dots,
clearly visible in the specimen illustrated by Mielke and
Casagrande (1987)Mielke, O.H.H., Casagrande, M.M., 1987. Sobre os tipos de Lepidoptera
deposita- dos em museus brasileiros. XI. Nymphalidae (Nymphalinae) descritos por José
Francisco Zikán. Rev. Bras. Entomol. 31, 399-403., was not mentioned in the original description of Zikán (1937)Zikán, J.F., 1937. Neue Nymphaliden-Arten und -Formen aus Brasilien.
Entomol. Rundsch. 54, 328-331.. It is worth mentioning that J.F. Zikán
was a great connoisseur of butterflies, and it is unlikely that he would have confused two
such different genera of Neotropical butterflies as Eueides Hübner, 1816
and Heliconius. Based on the present evidence, it is clear that the
specimen used by Zikán (1937) to describe H. melpomene f.
pyritosa var. fumigata is the one figured here ( Fig. 1). Therefore, H.
melpomene f. pyritosa var. fumigata
is not a variation of Eueides tales surdus, but alternatively, just a
variation of H. melpomene f. pyritosa,
which is a synonym of Heliconius erato amalfreda Riffarth, 1901. Finally,
although this specimen has no value as a name bearing type (this is an infrasubspecific
name; ICZN, 1999ICZN, 1999. International Code of Zoological Nomenclature, Fourth
edition. The International Trust for Zoological Nomenclature,
London., Article 10.2), this publication is
important both from an historical point of view (correcting a perfectly excusable mistake
in the literature), and also by clarifying the identity of a local variation of an
important and well-studied species of Heliconius.
