Micaria constricta
Micaria constricta is a small ground spider in the family Gnaphosidae, first described by Emerton in 1894. The species belongs to the genus Micaria, a group of spiders commonly known as 'ant-mimics' due to their resemblance to ants in both appearance and movement. M. constricta has a Holarctic distribution, occurring in North America and across northern Eurasia from Northern Europe to Middle Siberia. Records indicate presence in Alberta, Canada, and parts of the United States, as well as Svalbard and Russia.
Micaria foxi
Micaria foxi is a small ant-like spider in the family Gnaphosidae, first described by Gertsch in 1933. It belongs to the M. rossica/M. foxi species group, which forms a phylogenetic clade sister to M. formicaria. Like other Micaria species, it is distinguished by piriform gland spigots similar in size to major ampullate gland spigots. The species is known from North America, with records from the United States and Canada including Alberta and British Columbia.
Micaria gosiuta
Micaria gosiuta is a ground spider in the family Gnaphosidae, described by Gertsch in 1942. It belongs to the genus Micaria, which comprises small, fast-moving spiders often characterized by metallic coloration and ant-mimicking appearance. The species is recorded from the southwestern United States and Mexico.
Micaria longispina
Micaria longispina is a ground spider in the family Gnaphosidae, first described by Emerton in 1911. It is a small, active hunter found in North American ground habitats. The species belongs to a genus known for ant-mimicking species, though specific behavioral details for this species remain limited.
