Pselaphus bellax

As a member of Pselaphinae, Pselaphus bellax is minute (likely 1–2 mm), with a compact body, short elytra exposing most of the abdomen, and distinctly clubbed antennae. Species-level identification requires examination of male genitalia and other subtle morphological features; the genus Pselaphus is distinguished from related genera primarily by details of the foveal pattern on the pronotum and elytra, and the structure of the antennae and legs.

• Ants - symbioticPselaphinae are commonly termed 'ant-loving beetles' due to their frequent association with ant colonies; specific host ant species for P. bellax are unrecorded

• Other Pselaphinae genera (e.g., Batrisodes, Reichenbachia)Share minute size, clubbed antennae, and compact form; distinguished by pronotal and elytral foveal patterns and antennal structure
• Other Pselaphus speciesRequire detailed morphological examination, particularly of male genitalia and foveal arrangements, for definitive separation
