I would view both of these as potential syntypes and no more.  There is no
holotype as none was designated in the OD.  Holotypes are not to be
assumed, so any specimens (or specimen) would be a syntype.   No
lectotypification has occurred - only statements that a "type" (=syntype)
has been located.    Thus, you can designate the one of your choice
(stating why selected as lectotype and for what purpose).
