Langsat and Longkong are in fact the same species of fruit tree (Lansium domesticum), but their fruits are a bit different.
The name Langsat is used for the type where the skin is quite sticky to the fruit. The name Longkong is used for the type which has skin that is easily peeled off (without milky latex). The ping pong ball sized fruits grow together in big clusters.
