Identification
Pteroloma nebroides can be distinguished from other Pteroloma by its relatively large size within the and the characteristic pattern of elytral punctation. The species exhibits the diagnostic features of the Pterolomatidae: with a loose, elongate club of 3-4 segments that can be partially compressed; pronotum with lateral margins explanate and often toothed or angulate; and tibiae with distinct spurs. It differs from the more widespread Pteroloma fornicatum in body proportions and geographic distribution.
Habitat
Decaying wood, particularly in coniferous forests; has been observed in association with bracket fungi and in moist, rotting logs.
Distribution
Western North America; recorded from British Columbia, Washington, Oregon, and northern California.
Ecological Role
Contributes to decomposition of dead wood in forest ; likely serves as prey for various forest-dwelling and small vertebrates.
