Identification
Members of Orthoptochus can be recognized as Peritelini by their broad, short rostrum (the "broad-nosed" weevil form) and association with the tribe's characteristic body form. Within Peritelini, specific characters distinguishing Orthoptochus from related such as Peritelus or other entimine weevils are not well documented in available sources. The single described O. squamiger likely bears -like (squamose) covering on the , as suggested by the specific epithet.
Distribution
The precise geographic distribution of Orthoptochus is not clearly documented in available sources. The is North American in origin based on Casey's authorship and the distribution patterns of related Peritelini, but specific range data for O. squamiger or the genus as a whole is not established.
Similar Taxa
- PeritelusBoth belong to the tribe Peritelini and share the broad-nosed weevil ; Peritelus is more -rich and better documented, making it a likely comparison for identification purposes.
- Broad-nosed weevil genera in EntiminaeThe short, broad rostrum distinguishes Orthoptochus from weevils in other such as Curculioninae, which typically possess elongated, slender snouts.
