Notes on Pseudolucia jujuyensis (Lepidoptera: Lycaenidae: Polyommatinae)

The polyommatine lycaenid butterfly Pseudolucia jujuyensis Bálint, Eisele et Johnson, 2000 (Lepidoptera) was described on the basis of a single male from Coraya, Humahuaca, Jujuy, Argentina; its bionomics has remained unknown. Based on subsequently collected materials the species is now recorded from Yavi in Argentina and Torotoro in Bolivia (the latter representing a new country record). Eggs are recorded from Cuscuta sp. (Convolvulaceae), a suspected host plant of the larva. The bionomics and behaviour of the species are discussed. The species is considered to be endemic to the cold arid steppe (Prepuna) vegetation of low diversity, found along the eastern side of the Andes below the Altiplano in Bolivia and Argentina.
