Identification
Oeme costata can be distinguished from other Oeme by its costate (ribbed) , as indicated by the specific epithet. Members of the Oeme are characterized by elongated bodies and long typical of cerambycine longhorn beetles. The species may be separated from similar cerambycids in pinyon-juniper by its association with Pinus monophylla and its particular body sculpturing.
Habitat
Pinyon-juniper woodlands at high elevations (approximately 8300 ft / 2500 m). Documented from alpine coniferous forest with Pinus monophylla (single-leaf pinyon pine) and associated Juniperus osteosperma (Utah juniper).
Distribution
Southwestern United States. Documented from Kyle Canyon in the Spring Mountains of southern Nevada. Distribution records indicate presence in North America, specifically the United States.
Seasonality
Active in late summer and early fall. Observed in early September at high elevation sites in southern Nevada.
Host Associations
- Pinus monophylla - Observed on trunk at night

, active on tree trunks at night. Observed crawling on the trunk of Pinus monophylla after dark.
