Marinarozelotes lyonneti
Marinarozelotes lyonneti is a ground spider in the family Gnaphosidae, endemic to the Azores archipelago. Originally described by Audouin in 1826 as Drassus lyonnetii, this species was later transferred to the genus Marinarozelotes. It has been recorded from five islands in the central and western Azores. Like other gnaphosids, it is likely a nocturnal, cursorial hunter.

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.

Micaria medica
Micaria medica is a species of ground spider in the family Gnaphosidae, described by Platnick and Shadab in 1988. The genus Micaria comprises small, active hunters commonly known as ant-mimic spiders due to their resemblance to ants in movement and body form. This species is part of the diverse North American gnaphosid fauna. Very little specific biological information has been published for M. medica.

Micaria nye
Micaria nye is a species of ground spider in the family Gnaphosidae, described by Platnick and Shadab in 1988. The genus Micaria comprises small, active spiders commonly known as ant-mimics due to their morphology and behavior. This species is part of a taxonomically challenging group within Gnaphosidae, with species often distinguished by subtle genitalic and somatic characters.

Micaria pulicaria
glossy ant spider, Glossy Ant-spider
Micaria pulicaria is a small ground spider in the family Gnaphosidae, commonly known as the glossy ant spider. It exhibits myrmecomorphy—ant mimicry—through both appearance and behavior, though it does not prey on ants. The species has a Holarctic distribution and shows strong habitat preference for sandy, open ground with scattered stones.
