Also fits the photos in Neunzig, Fascicle 15.4 where he mentions the PM line being only moderately dentate basally. Also note the fused dark two spots basal to the PM line and the fuscous background of the basal wing and thorax. The slightly raised black spots on the basal wing are also seen in some photos at MPG and here. Found at light.
