Eburophora octoguttata

Eburophora octoguttata

Eburophora octoguttata White, 1855 is a medium sized Longhorn Beetle (Cerambycidae) endemic to south-eastern Australia. It has been reared from various species of Acacia (A. decurrens, A. irrorata and A. melanoxylon).
Spotted Longicorn (Eburophora octoguttata) -male An attractive dark brown longicorn with medium-length black antennae and thick femurs. Elytra had small pale yellow spots. The beetle would have been about 18 to 20 mm long.
Spotted on black wattle (Acacia mearnsii) - in a national park.
My thanks to WildFlower and Martin Lagerway for their help with the ID.
Note that this particular specimen is a somewhat aberrant colour form with extra spots as compared to the usual "factory issue" Eburophora octoguttata.

Appearance

Like its only congener (Eburophora eburata - also a south-eastern Australian endemic) it is a slender, narrowly elongate reddish brown beetle with sharp, darkened apices of the elytra and some ivory markings. Antennae are shorter than the body and do not sport spines.
The usual form of E. octoguttata has four oval ivory markings on each of the elytra (hence the name), but some specimen seem to carry extra spots.

Naming

The genus Eburophora was erected by White in 1855 for his new species Eburophora octoguttata and at the time was the only species in the genus (monotypy). Later, in 1874, the species Sophron eburatus Pascoe, 1865 was transferred to the genus Eburophora too.

Distribution

Eburophora spp. have been recorded from South Australia, Victoria, New South Wales and the Australian Capital Territory.

Status

Both species of Eburophora are relatively rare.
