Identification
Members of Dyschirius can be distinguished from other ground beetles by their small size (usually 3-5 mm), compact body form, and notably modified forelegs with widened tibiae adapted for digging. Within the , -level identification requires examination of male genitalia and detailed microsculpture patterns on the . Dyschirius alticola specifically may be distinguished from by subtle differences in body proportions and aedeagal structure, though published diagnostic features for this species are limited.
Distribution
Recorded from Canada and the United States in North America. Specific locality data beyond these national-level records is not widely published.

The epithet 'alticola' derives from Latin 'altus' (high) and '-cola' (dweller), suggesting the species was described from or associated with high-elevation , though this inference has not been explicitly confirmed in published sources.
Taxonomic History
Described by Swedish-Canadian entomologist Carl Lindroth in 1961, a prominent researcher on North American ground beetles. The was likely described based on material from the Canadian alpine or subalpine regions given Lindroth's research focus and the species name.
