Nearctic species and distributions

insularis (Howard, 1897): USA (FL)

scutellata (Howard, 1897): USA (CA, FL)

utilis (Noyes, 1982): Probably adventitiously introduced into USA (CA, Fresno County). Noyes (1982) reported this species was to be introduced into Ohio, but Johnson et al (2000) were unable to find any record that the species had actually been released there.

 

Remarks

I have a single specimen (RLZC) I identified as C. scutellata from Florida, marking a new state record.
