While S. hosei does not have an inat observation for mainland Malaysia, “On some scorpions from Malay Peninsula, with the description of a new subspecies of Lychas” from Lourenço 2007 cites a specimen of Lychas hosei (older synonym) collected from a cave in the same region- though this specimen is assigned to a new subspecies due to its lighter coloring that doesn’t match this one I photographed, I am at a loss for what other species this could be. I couldn’t find good resources for other species of Lychas in the range but that’s all I can think of.
