The Cassini Titan radar imaging team initially referred to the parallel marks in Titan's infrared-dark regions as "cat scratches". It eventually turned out they were dunes of stuff with a sandy consistency.
These asteroid grooves look to me sort of like the features on the Moon that geologists say are chains of collapse pits over a deeper fissure or collapsed lava tube. But I don't know if you would get something looking just like that on a small body.
