Entelides is the son of Herakles and Menippis who was one of King Thespius's daughters. During his stay in the court of King Thespius, Herakles impregnated 49 out of the 50 daughters of Thespius. One of these daughters was Kalametis who he lay with one night. The result of that particular encounter was Entelides.
"by Menippis he [Herakles] had Entelides"
