Pronotum with projecting latero-dorsal humps and rather short pubescence, pale, denser and scaly in middle.
Sexual dimorphism not eye-catching.
Mediterranean region, extends into southern Europe, but not far north. In palearctic catalogue mentioned as introduction in N.America, but no closer information found.
BugGuide data from eastern US, iNaturalist
has a CA record, which triggered the detection of P. variegatus
Data scarce; ecology described as near that of P. sexpunctatus (larvae scavengers in nests of solitary bees)
The species is not included in Nomina Insecta Nearctica, or mentioned anywhere to occur in North America. It is, consequently, omitted in keys.
With existing keys, it will key out as Ptinus bimaculatus, but is easily discriminated by shorter pronotal pubescence, adpressed and scaly in middle.
