Remarks: This largely Palaearctic member of the alpinum –species group (McInnes 1994 a) may, in Argentina, represent a new species or belong to one of the other reported South America species (D. (D.) alpinum, D. (D.) chilenense and D. (D.) stappersi). This South American record requires confirmation.
