WTF is newsbee?

Well, according to the Oxford Living Dictionaries...

...NEWS BEE is "any large or noticeable insect, typically a bumblebee, a beetle, or a hoverfly, whose appearance in a house or around a person is supposed, in popular folklore, to indicate that news of some kind will soon arrive".

This is, more or less, the idea.

What about - and why - suavekhmer?

Make an educated guess.
