Two specimens of what is probably the same species (they were immature, so difficult to identify) have been recognised from two sites in the Crimean mountains in Ukraine. The first specimen had been collected in 1989 from under a boulder in a natural mountain forest. The second was found on the floor of a cave, 10 m from the entrance. These are the first records of Trigonochlamydidae in Crimea. The Crimean specimens differ from Selenochlamys pallida in the same way as does S. ysbryda, making it likely that they are the latter species. Because it occurs in natural habitat in the Crimean Mountains, S. ysbryda is probably native there and may be endemic.
