Penichroa

Penichroa

*Penichroa* Stephens, 1831 is a small genus of nocturnal longhorn beetles associated with dry dead wood in warm Mediterranean landscapes. Known as the "Cellar Longhorn," its single European representative is notable for occasionally developing in stored wooden goods and timber, giving the genus a semi-synanthropic character. Adults are active from May to August and are attracted to fresh dead wood and ultraviolet light, making them detectable by both baited traps and light surveys. The genus ranges across southern Europe, North Africa, and western Asia, with scattered introductions elsewhere.
