I first heard about a possible Russian Ganymede Lander a year ago. Originally it was supposed to target Europa but since Europa Orbiter was canceled whereas JUICE was approved, the target has changed. It is still just a proposal but it seems to get more serious:

"The 4,000-kilogram Laplas-P1 spacecraft would feature an orbital module, OM, and a main propulsion system, MDU. Laplas-P2 spacecraft would consist of an MDU propulsion system and a 950-kilogram landing vehicle, PA. Following the Laplas-P1, it would first enter orbit around Ganymede and then dispatch the PA lander onto the moon's surface. The lander will deliver around 50 kilograms of scientific instruments on Ganymede's surface for a year-long studies. Both spacecraft will have an operational life time lasting from 11 to 13 years, including three years allocated for a pre-launch processing."

It reminds me the proposal of the Laplace mission few years ago. Most of people were sceptic about it, and finally JUICE was approved. So lets be optimistic for this one too !
