Hi KimberiEP,
In my novice's exuberance I accidently posted pix of 2 different laybird individuals to the same sighting (4634248), all taken at the same time. I have now updated that sighting to have just one, which is distinguishable by have roughly same sized spots all over, and a relatively rough surface to the wing covers. The 2nd one, which I've now added as a separate sighting, has relatively smooth wing covers, and most distinctively, a couple of pairs of spots that are distinctly smaller than the other spots. I suspect this may have added to some confusion about Spp, although your comments re disitinctions being dependent on genital differences suggest otherwise. Thought I should let you know, as well as thank you for your detailed comments which add to my understanding,
All the Best

Epilachna sumbana, E. vigintioctopunctata and E. vigintisexpunctata cannot be reliably separated using images like those above. Good images of the elytral apices (tips) can be used to separate sumbana (apices rounded) from vigintioctopunctata and vigintisexpunctata (apices 'distinctly angled'). The latter two can be separated only on examination of the genitalia.
