is this a Chrysotimus species, and if so is it possible to say if it's flaviventris or molliculus? It appears to have a black tip to the abdomen

thanks,
Jeremy

Quoting Grichanov (2006):

Genus Chrysotimus Loew
Antenna entirely black; apical section of CuA1 shorter than basal section; 1.5-2.5.......molliculus (Fallén)
­Antenna yellow, only postpedicel somewhat darkened; apical section of CuA1longer than basal section; 1.25-2.0... flaviventris (von Roser)

The antenna character matches flaviventris. Abdomen color is sexually dimorphic in the genus. He may have omitted it from the key for that reason.
