Never heard of it. There is a Hoya pusilla (valid) and a Hoya pubera (not sure if valid).

I looked up that plant on ebay (here's the image blown up: http://i.ebayimg.com/00/s/OTYwWDcyMA==/z/DfUAAOSwy4hUUSZo/$_57.JPG). It looks like good ol' Hoya nummularioides to me.

I generally treat new names from sellers I do not know with suspicion. Some slap new names on them in order to sell them higher and faster. Does not mean this one did it, and does not mean H. pubea does not exist - it just means to be skeptical.

A few other sites pop up in response to "hoya pubea" google search as well.

Hoya " pubea is extremely fragrant. Very fragile though if you are not careful moving their long branch. But, also very easy to propagate and care.

Yeah, no such thing as Hoya pubea. It is Hoya nummularioides. There is also a hoya pubera. I dislike made up names, as it adds to the already confusing world of hoya labels.

Check this site:

plantcareinfo.com

That plant on plantcareinfo is Hoya nummularioides, cara. There are several hoyas out there that go by invalid names, such as pubea, as I said earlier. I do believe (someone correct me if I am wrong) that Hoya pubea was the name used by Exotic Angels for Hoya nummularioides quite some time back. Exotic Angels is notorious for mislabeling and inventing new names for already named hoyas.
Apparently, this has actually been discussed before on GW/hoya forum.

Hoya nummularioides, it is then.
