ZooKeys 2014 421 65 89 32LN 260511 Berg, 1877 c: 233 Palustra Palustra argentina 13 78 species argentina  Taxon classification Animalia Lepidoptera Erebidae  Current identity.  Paracles argentina(Berg, 1877). It is a junior subjective synonym of Paracles laboulbeni(Bar, 1873).  Material. Described on the basis of six specimens from Corrientes (province of Corrientes, Argentina).  Type locality. Corrientes [province of Corrientes, Argentina].  MACN. a male syntype included in the Berg collection with a blue label with the inscription "Corrientes,"a red label with the inscription "TYPUS,"a white label with the inscription "Typus"and a white label with "argentina Berg" (handwritten by Berg), and a red label with the inscription "Lectotype ♂ Palustra argentinaBerg designated by Beccacece, Vincent & Navarro." We hereby designate it as lectotype [MACN]. It is in moderate to good conditions, although it has no antennae and the apex of the right forewing is torn (Fig. 21). From the Burmeister collection we designate two paralectotypes: a male specimen with a blue label printed "Corrientes"and a white label with the inscription "Typus;"a female specimen with a blue label with the inscription "Corrientes"and a white label with the inscription "Typus."Both specimens are in moderate to good overall condition, although rather worn.  Remarks. In the Berg collection, there is a female specimen with a blue label with the inscription "Misiones,"a red label with the inscription "TYPUS"and a white label with the inscription "Typus."It is in bad condition as it is missing the abdomen and the right antenna and the apices of both wings are damaged; according to the locality data, this specimen was incorrectly labelled as a type. Paracles argentina(Berg, 1877) was synonymized with Paracles laboulbeni(Bar, 1873) by Hampson (1901: 512). This latter species is from French Guiana and is characterized by the forewings having three transverse bands with little contrast. This feature is absent in the lectotype of Paracles argentina, so we revise the status of this species: Paracles argentina(Berg, 1877), sp. rev.  Palustra argentinaBerg, 1877c was redescribed under the same name as new by Berg (1878: 227).
