Ligyrus peninsularis is a scarab beetle in the Dynastinae (rhinoceros beetles), described by Casey in 1915. The occurs in the southwestern United States and Baja California region of Mexico. Like other members of the , it is likely associated with sandy or loose soil where larvae develop. activity patterns and specific ecological relationships remain poorly documented in published literature.

Identification
Ligyrus peninsularis can be distinguished from other Ligyrus by geographic range and subtle morphological features, though specific diagnostic characters require examination of or original description. The Ligyrus is characterized by males having a distinct horn or on the and pronotum, though this is generally less developed than in related dynastine genera. Females lack horns. Species-level identification in this genus typically requires examination of genitalia and detailed comparison with type material.
Habitat
Sandy or loose soil environments in arid and semi-arid regions, based on -level associations. Specific microhabitat preferences for this are not documented.
Distribution
Southwestern United States (California, Nevada) and northwestern Mexico (Baja California, Baja California Sur). The specific epithet 'peninsularis' refers to the Baja California Peninsula.
