Woytchugga Lacuna is one of the largest lakes of Titan. The lake is composed of liquid ethane and methane, and was detected by the Cassini–Huygens space probe. Indications are that it is an intermittent lake and so was named in 2013 after Lake Woytchugga near Wilcannia, Australia. (wikipedia entry)
A lacuna is an irregularly shaped depression having the appearance of a dry lake bed. On Titan they are named after lakes on Earth, preferably with a shape similar to the lacus or lacuna on Titan.
