Identification
Members of Drassyllus are small to medium ground spiders with cylindrical and characteristic arrangement diagnostic of Gnaphosidae: the lateral spinnerets are long and cylindrical, with the segment longer than the basal segment. -level identification within Drassyllus requires examination of genitalic structures. D. creolus may be distinguished from by specific features of the male and female , though published diagnostic characters for this species are limited in available sources.
Distribution
United States and Canada. GBIF records confirm presence in both countries, with the documented as present in North America generally.
