There is a very easy distinction between VW and PW. VW on the thorax has clear semicircular bosses. PW has an irregular network of ridges. The pattern of yellow scales is also different. This beast is PW on both counts. Check out the links I gave. There are more technical distinctions.
Can you post the link to the WAB example? There is no guarantee that the ID there is correct, of course.
