If you mean Pennsylvanian age of the orogeny, the same case exists in the south branch of the variscan orogeny, specially in Morocco. The orogeny lacks ophiolites knowing that is a subduction belt (see Simancas et al., 2005; Tectonophysics)
My later answer seems to be lost, written once I appreciated what you were working on. However I think ophiolites are lacking in a number of pre-Palaeozoic fold belts. Are there none at all in the Ouachita - for some reason I thought you had them in Arkansas but obviously you would know. Also I would have thought the tectonic setting of the fold belt, adjacent subduction marginsetc would have played a part in location of decollements and whether ophiolites were readily available to be obducted.
Please go to Dilek and Furnes, 2011, GSA Bull 123, p. 387-411: "Ophiolite genesis and global tectonics: Geochem.....lithosphere".
They report 310-320 Ma (very late Carboniferous/Pennsylvanian) continental margin ophiolites from Ust-Belaya, NE Russia.The information is taken from Ishiwatari et al. (2003) and Sokholov et al. (2003). Unfortunately, neither of these references is listed in the end, so I could not dig out more information for you. Having said this, I admire the high quality of the paper by Dilek and Furnes.
Yes, there are. This is where I would look: TienShan (Kazakhstan), Dzunghar , Central Mongolia, Solonker belt and eastern "Manchuria", and possibly Japan (deep water radiolarites).

PS I've attached an ophiolite animation that you may find interesting.
As already pointed out by Chris Scotese, you find ophiolites that have been obducted during Carboniferous/Permian time along the entire suture which marks the closure of the Palaeo-Asian Ocean in central and east Asia.
You may want to check out publications on the "Central Asian Orogenic Belt" or "Palaeo-Asian Ocean". My Chinese colleagues and me worked along the entire suture, and personally I focussed more on the area around the "Hegenshan Ophiolite" in Inner Mongolia/China. This ophiolite is thought to have formed ~300 Ma and has been obducted before ~270 Ma.
Feel free to have a look at my colleagues' and my publications, where you'll find more references more closely related to actual ophiolite formation/obduction along the southern margin of the Central Asian Orogenic Belt, especially in China.
Thanks, Paul. This is helpful. I do not know much about the "Central Asian Orogenic Belt" or "Palaeo-Asian Ocean". I will definitely check out your publications as soon as I can.
Thanks, Chris, I will read the references related to "TienShan (Kazakhstan), Dzunghar , Central Mongolia, Solonker belt and eastern "Manchuria", and possibly Japan (deep water radiolarites)" as soon as I can..
