There is no such thing as Sharinnegan. There is just the original doujutsu Rinne Sharingan, single eye located in the forehead, then Sharingan and Rinnegan. Sasuke has both the Sharingan and Rinnegan. The only reason why Sasuke's Rinnegan has tomoe, is because he can use both doujutsu at once, meaning Sasuke Rinnegan's tomoe are actually Sharingan tomoe.

In Gaiden we saw his Rinnegan without any tomoe when he was low on chakra and it looked like the ordinary Rinnegan of Hagoromo and Madara. Then when he activated his Mangekyou Sharingan, the tomoe appeared, what more proof do people need?
