Blackburnia rugosa Liebherr & Porch

Rugose Blackburnia Ground Beetle (Blackburnia rugosa)

The Rugose Blackburnia Ground Beetle was described in 2015, it is known only from several subfossil remains that had been found in the deposits of the Makauwahi Cave on the island of Kaua’i, Hawaiian Islands.

The species reached a size of about 0,8 to 1,1 cm and is distinguished from its congeners by its robust sclerotization. [1]

Blackburnia blaptoides (Blackburn)

Konahuanui Blackburnia Ground Beetle (Blackburnia blaptoides)

The Konahuanui Blackburnia Ground Beetle was described in 1878, it was apparently restricted to the Pu’u Konahuanui, the tallest peak of the Ko’olau Range on the island of O’ahu, Hawaiian Islands.

The species is thought to be extinct due to predation by introduced ants. [1]

Blackburnia micantipennis (Sharp)

Waimea Blackburnia Ground Beetle (Blackburnia micantipennis)  

The Waimea Blackburnia Ground Beetle was described in 1903, it occurred only at elevations of 600 to 1270 m on the leeward reaches of the Waimea Canyon on the island of Kaua’i, Hawaiian Islands. It is thought to have been a riparian species, since all localities, at which this species was found, are along the tributaries of the Waimea River.  

The last specimens of this species were apparently collected in 1935 and it is now thought to be possibly extinct. [1]

Blackburnia mothra Liebherr & Porch

Mothra Blackburnia Ground Beetle (Blackburnia mothra)

This species was described in 2015, it is one of several, mostly very large ground beetle species that are known exclusively from subfossil remains found in the makauwahi Cave on the island of Kaua’i, Hawaiian Islands.

The Mothra Blackburnia Ground is the second-largest member of its genus, it died out shortly after the arrival of the first Polynesians on the Hawaiian Islands. [1]

Blackburnia terebrata (Blackburn)

Terebra-bearing Blackburnia Ground Beetle (Blackburnia terebrata)

The Terebra-bearing Blackburnia Ground Beetle was described in 1881, it was endemic to the eastern part of the island of Maui, Hawaiian Islands.

The species is known to have been one of the species associated with the formerly abundant but now mostly absent endemic koa forest, it was recorded under stones or logs outside the koa forest. [1][2][3]

Blackburnia burneyi Liebherr & Porch

Burney’s Blackburnia Ground Beetle (Blackburnia burneyi)

Burney’s Blackburnia Ground Beetle was described in 2015, it is known only from subfossil elytra that had been recovered from sediments from the Makauwahi Cave on the island of Kaua’i, Hawaiian Islands.

The species is thought to have been macropterous.

Burney’s Blackburnia Ground Beetle apparently was a lowland species and thus was among the first invertebrates to be wiped out by the Pacific Rats (Rattus exulans (Peale)) that had been introduced to the islands by the first Polynesian settlers. [1]

Blackburnia octoocellata (Karsch)

Eight-eyed Blackburnia Ground Beetle (Blackburnia octoocellata)

The Eight-eyed Blackburnia Ground Beetle was described in 1881, it was endemic to the island of Maui, Hawaiian Islands.

This beetle is one of several within its genus that are associated with the endemic Koa Acacia (Acacia koa A. Gray) in one way or another, this species for example was recorded under exfoliating bark of the koa.

The nearly complete destruction of large parts of the formerly abundant koa forests lead to a collapse of many populations of endemic invertebrates, some are now completely extinct – like this beetle. [1][2][3]

Blackburnia tantalus (Blackburn)

Tantalus Blackburnia Ground Beetle (Blackburnia tantalus)

The Tantalus Blackburnia Ground Beetle was described in 1877, it was very abundant at that time and was found along both the Ko’olau –  as well as the Wai’anae Mountain Ranges in central O’ahu, Hawaiian Islands.

The species possessed a well-developed flight apparatus, it appears to have not been specialized in any way, most specimens were collected at elevations between 445 to 600 m, mostly in moss mats on tree trunks as well as under the bark of dead trees. 

The Tantalus Blackburnia Ground Beetle was not recorded during any of the more recent surveys and is now feared to be extinct. [1][2]

Blackburnia transiens (Sharp)

Ephemeral Ground Beetle (Blackburnia transiens)  

The Ephemeral Ground Beetle was described in 1903, it was endemic to the Makaweli region of the island of Kaua’i, Hawaiian Islands, where it appears to have been restricted to arboreal micro habitats.
