Pseudoxylosteus ornatus (LeConte, 1873)

Pseudoxylosteus is a genus of flower longhorn beetles in the family Cerambycidae. There is a single species in Pseudoxylosteus, P. ornatus, found in the western United States. It is about 10 mm in length.[1][2]

Description

Adults measure approximately 10–13 mm in length. The body is dark brown to black with lighter markings on the elytra. The antennae are slightly shorter than the body length. Like other members of the subfamily Lepturinae, the species is associated with flowers and is believed to feed on nectar and pollen.[3]

Distribution

Pseudoxylosteus ornatus is native to the western United States, with most records from California. Additional observations have been reported from southern Oregon, particularly in the Siskiyou Mountains.[4][5]

Taxonomy

The species was originally described by John Lawrence LeConte in 1873 and was later transferred to the monotypic genus Pseudoxylosteus by Sama in 1993.[6]
