Type material examined.

Pogonomyia aldrichi - Holotype male labelled " INHS /Insect Collection/238,899; "Moscow Ida/v.22.13"; " TYPE / Pogonomyia / Drymeia aldrichi / ♂ [red]" ( INHS) .

Other material examined.

2 females: Nearctic: USA: Idaho: Moscow ( INHS) .

Distribution.

Nearctic: Canada (Alberta), USA (Washington to California (see remarks), Wyoming) .

DNA barcode.

None available.

Remarks.

While California was listed in the distribution of D. aldrichi by Huckett (1965b), the species was not included in a subsequent work by the same author on the fauna of California ( Huckett 1975). We therefore suspect that early records of D. aldrichi from California belong instead to another species, possibly the very similar D. amnicola , described by Huckett in 1966. As mentioned in the DNA barcoding section below, both the distribution and the limits of D. aldrichi are currently uncertain and additional data will be required to clarify the issue.
