Yes I should have mentioned that in my other list. The images in my reference clearly show turbinata having more white on the anterior portion of the dorsum. It also shows that conica has more of a pointy black pattern on the posterior dorsum while turbinata has more of a rounded black pattern. (I have a feeling pattern would be hard to use in the case of juveniles) Here would be two examples of patterns that match the drawings in my guide:
conica


turbinata (drawing is somewhat between the following, not quite as dark anteriorly as the first and not quite as light as the second)


I'm afraid my guide does not mention the non-candian species such as berlandi, caroli & walckenaeri. Caroli is already in the guide and does not appear to be very similar to either of the above. However, I don't remember what I've read about berlandi or walckenaeri.

- more info. So I revisted Levi's publication and see that both berlandi and walckenaeri have 4 projections at the end of the abdomen.. not much chance of confusing those with conica & turbinata.

I'd lean toward conica on this one.
