Conotyla vista Shear

Natural Tunnel Miliped (Conotyla vista)

This species was described in 1971; it is only known from a single specimen that was found in one of the so-called Natural Tunnels, a sandstone formation in the Grandview State Park in Raleigh County, West Virginia, USA.

The male holotype is the only known specimen. The type locality … is a ridge of heavily faulted, coarse sandstone overlooking the 1200 foot [365,76 m] deep gorge of the new River. The Natural Tunnels are roofed crevices formed by downslope creeping of sandstone blocks and are long enough to have totally dark areas and at least some troglophilic species (…), but C. vista shows no cave modifications. ….” [1]

The species has not been found since and is considered possibly extinct, however, this certainly is not a true cave species and might sooner or later be found in the vicinity of its original type locality.

Rubus concameratus H. A. Davis & T. Davis

West Virginia Blackberry (Rubus concameratus)

The West Virginia Blackberry was described in 1953, as it name implies, it is only found in West Virginia, USA, where it is known from five counties, however all reports are historic with the latest one dating from 1957.

The West Virginia Blackberry thus might be extinct.

However, this species is not recognized by all botanists and is sometimes considered a synonym of the Allegheny Blackberry (Rubus allegheniensis (Porter) Porter) (see photo).

Rubus huttonii Bailey

Hutton’s Dewberry (Rubus huttonii)

Hutton’s Dewberry is, or rather was, a somewhat prostrate, creeping shrub with 1 to 2 cm large, white flowers that was known from only three nearby localities in West Virginia, USA.

The species was not recorded in recent searches and might be extinct, however, according to some authors it may also be synonymous with another species, the Swamp Dewberry (Rubus hispidus L.) (see photo).

Horologion speokites Valentine

Arbuckle Cave Ground Beetle (Horologion speokites)

The Arbuckle Cave Ground Beetle was described in 1932; it is still known exclusively from the type that was collected one year prior in a cave named Arbuckle Cave, which is supposed to be located in the Greenbrier County of West Virginia, USA.

This species is known only from the holotype collected in a cave three miles north of Lewisburg, near Maxwelton, in southeastern West Virginia. The cave has two rather small rooms connected by a narrow, descending, and tortuous passage. The specimen was found in the lower room, which was wet, muddy, and quite dark.” [1]

The biology of this species is completely unknown, it is not even certain that it is indeed a true cave species; it might now be extinct.
