A son of Hippocoon, who had a heroum at Sparta conjointly with his brother Sebrus. The well near the sanctuary was called Dorceia, and the place around it Sebrion. (Paus. iii. 15 § 2.) It is probable that Dorceus is the same personage as the Dorycleus in Apollodorus (iii. 10. § 5), where his brother is called Tebrus.
