Mike, this is a synonym for Diabrotica barberi. Please check if names are valid before making new species-pages
I see you with Ed Riley have made many additions lately. Great work!

D. longicornis (Say) still valid name...

Diabrotica longicornis (Say, 1824) - is still valid.

This widespread subspecies was elevated to full sp. status:
Diabrotica longicornis barberi R. Smith & Lawrence, 1967

Check page 79 of Riley et al. 2003 to confirm. (1)

Hope this helps, Mike
