The palp -
looks spot on, so I would support the ID. It sounds like it might only apply to females, but do you happen to see either the "triangular black spot" on the ventral side and/or the scleotized area near the pedicel referred to by Levi 1957? Nice to have this in BG, since it also occurs in CA and I've been looking for it! :)
