The single strong bristle at the base of R4+5 is normally of generic significance. Most genera have at least a few weak bristles. The exceptions with one strong bristle are not closely related to each other.
Is the first post-sutural supra-alar weak or strong?
The first post-sutural supra-alar (red arrow) seems to be very strong, at least as strong as the notopleural bristles (yellow arrow).
NOTE: the left supra-alar has been broken off the specimen and the right one (the one used in the photo) has a broken apical portion.
