Explanation of Names
Ptinus variegatus Rossi, 1794
Size
3-4 mm
Identification
Elytra with two wavy, transversal white bands, first band usually with extensions to shoulder and along side margin.
Pronotum with projecting latero-dorsal humps and rather short pubescence, pale, denser and scaly in middle.
Sexual dimorphism not eye-catching.
Range
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 here.
Habitat
Data scarce; ecology described as near that of P. sexpunctatus (larvae scavengers in nests of solitary bees)
Remarks
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.
