Cybocephalus nipponicus for California? - Cybocephalus

Cybocephalus nipponicus for California? - Cybocephalus
Long Beach, Los Angeles County, California, USA
January 8, 2015
Size: ~1mm
It certainly looks the part, but what's it doing in California? SBMNH has a single state record appended with a question mark and no collection info, and I don't know of any intentional release programs involving this species in CA.

Apologies for the bad photo; found the beetle on my arm while working and I didn't have much time to sit down with it and get good pics. And apologies for my extended Bugguide absence.

hope Andy Cline knows the answer
might well be adventive

Moved from Beetles.

 
Dr Cline's response:
"I consulted with Trevor Smith, and both of us agree that this is likely C. nipponicus. However, we both agree that without a dissected specimen and a clear view of the male genitalia that no definitive identification can be made. There are other species of Cybocephalus that possess a yellow head and pronotum. The potential capture of this species in Long Beach would not be too surprising as C. nipponicus is a widely distributed species and Long Beach is major trade center on the west coast. If the photographer of the specimen happened to retain a voucher, please have them send the beetle to me and I can provide a more definitive identification with verification from Trevor. Sorry we couldn't be of more help, but it's hard to say 100% for sure on some these beetles without seeing the genitalia."
