Broscodera
Broscodera is a genus of ground beetles in the family Carabidae, established by Lindroth in 1961. The genus comprises at least four described species distributed across East Asia and western North America. Members of this genus belong to the subfamily Broscinae, a group of predominantly nocturnal beetles often associated with moist habitats. The genus shows a disjunct distribution pattern, with species occurring in China, Nepal, and the Pacific Northwest of North America.
Broscodera insignis
Broscodera insignis is a species of ground beetle in the family Carabidae, subfamily Broscinae. It was originally described as Miscodera insignis by Mannerheim in 1852 and later transferred to the genus Broscodera. The species is documented from North America, with distribution records including Alaska, Canada, and the contiguous United States. As a member of the subfamily Broscinae, it belongs to a group of ground beetles often associated with cool, moist habitats.
Miscodera
A monotypic genus of ground beetles (Carabidae) containing only Miscodera arctica. The genus has a circumpolar Arctic distribution with disjunct populations in northern New England. Its taxonomic placement has been historically disputed, currently assigned to subfamily Broscinae though formerly placed in Trechinae.
Miscodera arctica
Miscodera arctica is a ground beetle (family Carabidae) and the sole species in its genus. It has a Holarctic distribution, occurring across northern regions of North America and Eurasia. The species is placed in the subfamily Broscinae, a group of carabid beetles often associated with cool or montane habitats. As the only member of Miscodera, it represents a monotypic lineage within the diverse ground beetle fauna.
Zacotus
Zacotus is a monotypic genus of ground beetles in the family Carabidae, containing the single species Zacotus matthewsii. The genus was established by LeConte in 1869 and is classified within the subfamily Broscinae. The sole species represents a rare example of a genus with no known congeners.
Zacotus matthewsii
Zacotus matthewsii is a ground beetle and the sole species in its genus. It belongs to the subfamily Broscinae within Carabidae. The species is endemic to western North America, with records from Alaska, Canada, and the contiguous United States. Its monotypic genus status makes it taxonomically distinctive among North American carabids.
