Remarks: This species often occurs rarely and in small numbers and has been reported with extremely high levels of intra-specific variation and a wide geographic range (i.e. numerous mainly Holarctic localities with single localities in other zoogeographical regions, Ramazzotti & Maucci 1983, McInnes 1994a). However, these properties are also symptomatic of a species complex, so we suggest this species requires integrative taxonomy (molecular and morphology) to establish the species sensu stricto and validity of South American examples.
