Blackburnia is a genus in the beetle family Carabidae, from the Hawaiian Islands.[1][2][3] More than 40 of Blackburnia's 140 species have been described since 2000. 14 species have not been recently observed (over the past 50 years on Oahu or 100 years on the other islands). All the known extinct species have been discovered since 2015.[1][2][3]
Distribution
The Hawaiian Islands are a string of islands increasing in age from the "big island" of Hawaii in the southeast the youngest, at 500,000 years old, with successively older islands toward the northwest. Kure Atoll, in the far northwest of the Hawaiian chain, has an estimated age of 28 to 30 million years. The beetles of Blackburnia have been successively colonizing and proliferating these islands since the Miocene period, 5 to 23 million years ago, and there are now more than 130 extant species of Blackburnia endemic to the Hawaiian Islands.
Taxonomy
The species of Blackburnia are divided into four subgenera. The species Blackburnia mandibularis, with its own subgenus, Protocaccus, is a sister taxon to the other groups. It lives and breeds along streams in riparian moss on the island of Kauai.
The next clade to diverge in the evolutionary tree is Colpocaccus, with four flight-capable species.
The subgenera Blackburnia and Metromenus are monophyletic sister taxa. The subgenus Blackburnia has about 57 species, based on a flight-capable ancestor. Its species are the most morphologically diversified of the four subgenera. The subgenus Metromenus contains about 71 flightless species.[2]
