Except for the lack of color
Except for the lack of color dimorphism between male and female, the dark blue highlights on the body and legs, and the fifth costae is absent or reduced to a faint line in the pubescence. Unfortunately I can't get the dark blue to show in the pictures (I don't have your excellent setup). Also note the hind tibia in both sexes, compared with that of densiventre.
