Let’s assume all Sasquatch type critters are a bipedal Gigantopithecus/Hominim crossbreed...Gigantohominim. That would make the Batsquatch Gigantohominim Chiropter. Gigantohominim vulgaris could be used for the common Bigfoot/Sasquatch critters typical of the mythology of tha Americas, and Gigantohominim Mons would be something like a Yeti that is exclusively found in mountainous regions.
