Remarks.

The comparison of type material from D. longiseta Sorokina and Pont from Russia with a series of high elevation specimens from Colorado, USA, housed in the CNC and matching the original description of D. spinitarsis has led us to recognise D. longiseta as a junior synonym of D. spinitarsis . This change effectively expands the distribution of D. spinitarsis to the Palaearctic region and while DNA barcodes are currently only available for Russian specimens, D. spinitarsis is such a large, distinctive species (strong spines on mid tarsomere 1, distinctive chaetotaxy of fore and mid coxae in the male, high elevation distribution) that we are quite confident in this new synonymy .
