This species is recorded from four locations representing four sites. Tyrrheniberus villicus is another taxonomically well defined palaeoendemic species which is characteristic for the fauna of Sardinia. It occurs only in a small part of the central eastern inland mountains where it lives in isolated populations. The four known sites have provisionally been defined as locations. Road construction, tourism development and recreational activities are potential threats. This species is hence assessed as Vulnerable (VU) D2.
