palerct and others regions

[Hellmuth Forstner]

Your question:I would like to know,  what is exactly palerctic and
region.  Is there any web page to show latest regions on the earth?

I think you mean palearctic!!
The holarctic biogeographical region comprises the temperate and
coldadapted biota of the northern hemisphere. The northamerican
continent is the  nearctic, Europe and Asia the palearctic region.
