Yeah, but for some reason only seemed to come to light now, maybe it was only deemed an acceptable taxa from now, I don't know. I was a bit confused with the original date of publishing, but I know it takes a while to be accepted. It's certainly Makararaja chindwinensis, Roberts 2007
Right this is an update from a few months ago... PFK has just done a quick article and theres a picture...
"A new genus and species of freshwater stingray has been described from Myanmar.
The new stingray, named Makararaja chindwinensis, is described from the Chindwin River (a tributary of the Irrawaddy River in northern Myanmar) in a paper by Tyson Roberts published in a recent issue of the Natural History Bulletin of the Siam Society.
Makararaja chindwinensis is closely related to the flagtailed stingray genus Pastinachus, but differs from it and other stingray genera in the family Dasyatidae in having a nearly round disc, with the dorsal surface having pearl organs and denticles so small as to appear almost lacking, 105–107 pectoral-fin pterygiophores, and tail with a long, low-lying fin fold.
Together with Pastinachus, Makararaja is considered to form a new subfamily Pastinachinae.
The generic name comes from the Sanskrit makara, meaning crocodile (but also referring to the gateways of Hindu temples shaped like the open jaws of a crocodile) and the Latin raja, meaning a skate or ray fish; the name refers to the characteristic jaw shape of this fish (common to all pastinachine rays).
The specific epithet is named after the habitat (Chindwin River) of the fish. Makararaja chindwinensis represents the first record of a freshwater stingray from the Irrawaddy River drainage."
