There is a newer model that I don't believe has been added to EBI yet. I have seen her listed as Karina and Yuliya in a few websites. As far as I know, Karina/Yuliya is currently featured in the sites below.
TeenSexMovs.com (Karina)
TeenSexMania.com (Karina)
TeenDreams.com. (Yuliya)
The following link is her page as Yuliya at TeenDreams.com: http://tour.teendreams.com/cms/model/view/i=6362
Below are a couple of pics from TeenSexMovs.com and TeenSexMania.com.
