Yes, that's the one that caught my eye, R. tetrasperma! (Will never admit how much time I spent finding that name.) I suspect there may be more out there than we think, probably almost always ID'd as M. deliciosa.
Since I posted this question, I've realized there are quite a few species (duh, listed here in the DB.) Can't find pics of most but none of the ones I've seen look anywhere near as exciting as 'mini Monstera.' Nobody seems to have most them, or pics of them, at least in the realm of English-language websites/forums/FB. On FB, I did find someone who has a different one with much smaller leaves, a diff species. Not anywhere near as exciting as R. tetrasperma. I didn't mention the species in my original question because it never occurred that anyone would have the even less common ones if the 'main' species is so rare. Could also be a case of most of them being ID'd as Philodendrons or other similar genera, or mistaken perception on my part.
SO sorry you lost that plant, Lin! TY so much for the pic. OMG, it was stunning, perfect!! So glad you at least have that fantastic pic. (Wish I had a pic of the rubber tree I lost about 7-8 yrs. ago, also to a cold accident.) Do you remember where you'd gotten it?
