Dysschema terminata (Guérin-Méneville, 1844)

Remarks.

Males and females are sexually dimorphic for wing patterns. Collections carried out at Boracéia Biological Station (Salesópoplis, SP, Brazil) allowed the pairing of sexes ( Moraes et al. 2017). Additionally, handwritten notes by an unknown author were found at the Smithsonian Natural History Museum, highlighting the possibility that D. terminata was the female form of D. fantasma . Despite the sexual dimorphism, common characters present in both sexes corroborate the hypothesis that the distinct forms are the same species, such as the red macules on the costal margin and on the tornus region, and tufts of red scales on the terminal portion of the abdomen ( Moraes et al. 2017).

Males of D. terminata have wing pattern similar to that of D. subapicalis , differing from the last by the reduced “V” shaped semi hyaline region on the forewings, by the hindwing with a yellow discal region and veins outlined with dark brown scales, and an abdomen with two yellow bands ventrally. Males are also polychromatic on the hindwings, recorded by a series of specimens collected at the Boracéia Biological Station, in Salesópólis, showing the red submarginal band quite evident or gradually reduced until its complete absence.

Material examined.

3 males, Brazil, Santa Catarina, Hansa?; 1 male, Brazil.
