The species is classified within the tribe Zuphiini, a group of carabid beetles often associated with ant colonies or exhibiting myrmecophilous tendencies. Very little specific biological information has been documented for this particular species. It is currently treated as a valid species in the genus Thalpius, though some classifications place it within the subgenus Pseudaptinus (Thalpius). The species epithet "pygmaeus" refers to its small size.
