OK, many thanks, Stephane. I thought rufiventris would have more visible orange on the thorax, but maybe not visible from this angle, and there must be another character you are using to separate this from subventa.

Phaonia rufiventris : 1 presut ac. ; scutellum entirelly orange (at most darkened at extreme base ; mid tibia with 3-4 post. setae; fore tibia without p. setae. Phaonia subventa : 2 presut ac. ; scutellum almost always broadly darkened at base ; mid tibia with 2 p. setae ; fore tibia with p. setae. (There is a third one, Phaonia bitincta.  ).
Stephane. |

Many thanks Stephane, great feedback; I may be able to separate these two now, unless the third one confuses me!
