For this I believe we can call as Polynesian group...

lets say before the qin unification, i believe we were separated.

No, I think they mean Malay in Indonesia. Or are you telling me Malay in Indonesia =/= Malay in Malaysia?

Is there such thing as sub ethnic group in Indonesia in the first place?

Most likely different definitions.

Things can be classified. Just that different people might classify it differently.

Indonesians did believe in Pan-Malay (or whatever it is called) Nusantara. At least during pre-Merdeka and Konfrontasi era.

Malay race, a racial category used in the late 19th and early 20th century to describe Austronesian peoples
Ethnic Malays, the ethnic group located primarily in the Malay peninsula, and parts of Sumatra and Borneo

Screw history. Let just talk about modern day definition. If we talk about history all human is from Africa.

What is this Pan Malay Nusantara? Is it a supra ethnic or sub ethnic?

I notice Malay can mean Malay race and Malay ethnic.
http://en.wikipedia.org/wiki/Malay

Wikipedia here correct or not?

Is this Pan-Malay a supra ethnic/large group similar concept to Polynesian group as mention by gm_18300.

Pan-Malay Nusantara,Malay race and Malay ethnic, these three things same concept or not?

Is it same like Italian, British, French and German subgroup of European race?

Malay race =  Malay sub ethnic, Bugis sub ethnic, Javanese sub ethnic, Balinese ethnic sub

European race =  Italian sub ethnic, British sub ethnic, French sub ethnic, German sub ethnic

Mongoloid race =  Han sub ethnic, Japanese sub ethnic, Korean sub ethnic, Mongolian sub ethnic, Manchu sub ethnic

Do I get it correct?

^ mah point exactly, i agree to this.

The concept of a Malay race was originally proposed by the German scientist Johann Friedrich Blumenbach (1752–1840), and classified as the brown race.[1]

In his 1775 doctoral dissertation titled De generis humani varietate nativa (On the Natural Varieties of Mankind), Blumenbach outlined four main human races by skin color, namely Caucasian (white), Negroid (black), Native American (red), and Mongolian (yellow).

By 1795, Blumenbach added another race called 'Malay' which he considered a subcategory of both the Ethiopian and Mongoloid races. The Malay race belonged to those of a "brown color: from olive and a clear mahogany to the darkest clove or chestnut brown." Blumenbach expanded the term "Malay" to include the native inhabitants of the Marianas, the Philippines, the Malukus, Sundas, Indochina, as well as Pacific Islands like the Tahitians. He considered a Tahitian skull he had received to be the missing link; showing the transition between the "primary" race, the Caucasians, and the "degenerate" race, the Negroids.

Blumenbach writes:

Malay variety. Tawny-coloured; hair black, soft, curly, thick and plentiful; head moderately narrowed; forehead slightly swelling; nose full, rather wide, as it were diffuse, end thick; mouth large, upper jaw somewhat prominent with parts of the face when seen in profile, sufficiently prominent and distinct from each other. This last variety includes the islanders of the Pacific Ocean, together with the inhabitants of the Mariannas, the Philippine, the Molucca and the Sunda Islands, and of the Malayan peninsula. I wish to call it the Malay, because the majority of the men of this variety, especially those who inhabit the Indian islands close to the Malacca peninsula, as well as the Sandwich, the Society, and the Friendly Islanders, and also the Malambi of Madagascar down to the inhabitants of Easter Island, use the Malay idiom.[9]
