Yes.
The only way to tell
L. anisitsi and
L. pardalis apart {assuming we do consider them separate species} would be with a "belly" shot - if it's vermiculated(sp?) it would be
L. anisitsi, and if it's spotted it would be
L. pardalis.
Jon Armbruster considers Liposarcus, Pterygoplichthys and Glyptoperichthys all to be Pterygoplichthys, and there's a "key" to identification of described species here:
