As mentioned earlier, the "CT" acronym for "Cambodian tiger" was originally meant to designate the Mekong River basin population of Datnioides pulcher, i.e., widebars from Cambodia, Vietnam, Myanmar (Burma). The Mekong population was distinguished from the Chao Phraya population of D. pulcher, i.e., widebars from Thailand, which were given the ST acronym for "Siamese tiger", but both are considered the same species.
IMO, the "controversial tigers" depicted on the other website are all D. pulcher, although they exhibit some "flaws" like split bars and three tail stripes. They all have middle bars that stop short of, or come to a point at, the ventral surface and are, IMO, D. pulcher. Many of the D. pulchers from Vietnam that were imported into the U.S. about two years ago exhibit these characteristics.
