Orthoptochus squamiger
Casey, 1888
Orthoptochus squamiger is a of broad-nosed weevil in the Curculionidae, Entiminae. First described by Casey in 1888, this species is known from a very limited number of observations and museum records. It belongs to the tribe Peritelini, a group of weevils primarily associated with woody plants. The species appears to be restricted to the southwestern United States and adjacent Mexico.

Identification
Distinguishable from other Orthoptochus by the presence of dense, -like setae (squamose covering) on the and body, as suggested by the specific epithet "squamiger" (scale-bearing). The Orthoptochus is characterized by a broad, short rostrum typical of Entiminae weevils, with inserted near the base. Detailed diagnostic features require examination of genitalia and other minute morphological characters.
Distribution
Known from southern California and Baja California, Mexico. Records indicate presence in coastal and near-coastal regions of southwestern North America.
Similar Taxa
- Other Orthoptochus speciesClosely related share the broad rostrum and general body form of Entiminae weevils; O. squamiger is distinguished by its pronounced squamose covering.
- Other Peritelini generaMembers of the same tribe share similar ecological associations with woody vegetation and broad-nosed ; accurate identification requires examination of tarsal structure and other fine details.

Taxonomic Note
The Orthoptochus is part of the diverse weevil tribe Peritelini, which contains numerous with limited published biological data. The specific epithet "squamiger" refers to the -like covering of setae on the body surface.
Data Deficiency
With only two observations in iNaturalist and sparse museum records, this exemplifies the many poorly known entimine weevils whose and distribution remain largely undocumented.
