Identification
Can be distinguished from other Colliuris by geographic restriction to the Cayman Islands and from C. tetrastigma by the elevation to full species status based on morphological differences. The slender, -mimicking form separates it from superficially similar ground beetles such as Elaphrus or Asaphidion, which may also be mistaken for tiger beetles.
Distribution
to the Cayman Islands (Grand Cayman, Cayman Brac, and Little Cayman).

- Elaphrus spp.Both are slender ground beetles that may be mistaken for tiger beetles by collectors, though Elaphrus has a more robust build and distinct elytral sculpturing.
- Asaphidion spp.Similar -mimicking appearance and small size; Asaphidion is a more recent introduction to some regions and may be confused with Colliuris by collectors.
