I haven't seen an official definition from an official website (eg. IUCN, CITES, WAZA, ICZN etc.), just personal opinions. Although the examples and usage of the word I have found in papers agrees with my understanding of the words -
intergrade: the offspring of two different subspecies (within the same species)
hybrid: the offspring of two different species.
This is how mammal people and birdos have been using the terms for many, many years. In his book "The Sibley Guide to Birds" Alan Sibley states exactly this. It doesn't matter if it happens in the wild or in captivity, the name refers to the genetics of the parent's population. If the ranges of the parents overlap in the wild they can be referred to as natural or naturally-occuring intergrades or hybrids.

In the first post I simply reported what was told to me. I was relaying thisto the forum because people were refering to the paper and the research and speculating on why it hadn't been published, and also on the results of the research. I didn't offer my views because:
a) I was providing the information to the membership so they could come to their own conclusion without my bias interfering, and
b) until I have actually read the papers and critically evaluated their methodology, results and conclusions, my arguments are based upon what I was told briefly over the phone.

They are indeed intergrades - the offspring of two different subspecies within the one species - this does not mean they are a separate or new species.
Furthermore, you previously said:

This is incorrect. The results as I reported them state that there are
no subspecies; therefore there can be
no intergrades. The different pattern variations we see over the range of
Morelia spilota is simply clinal.
