User blog comment:Salubri/Hollow. Arrancar, Espada & Vasto Lorde/@comment-44061-20100818012209

Well I would go with Starrk, Baraggan, Harribel, Ulquiorra and considering Yammy's position as 0 he maybe included as well or not, thats up and down. Grimmjow Im not to sure I would assume so but he was not humanoid as a Hollow that last time he was seen in that form and only adjuchas trying to evolve to Vasto Lorde. As for Nnoitra Im starting to lean towards no he wasn't.

I wouldn't put to much into the idea that Espada didn't know they weren't Vasto Lorde that makes no sense. The point was Aizen was looking for Vasto lorde to make up his Espada. Just because they were looking for more didn't mean they weren't aware of them. Hollows know power and we can't forget that are said to be able to count the number of Vasto lorde on ones hands and they are extremely reclusive.
