I find no historical reference for this term. I would say made up for the song lyrics.
Let me edit my answer a little. I did spend time searching for this term, and found no website, no link to Sumerian, Babylonian, or Demonic mythologies that I tried linking with the term. No image showing it. No Book referencing it. That is what I meant by finding no reference to this term. (I hope someone does find something, so I can learn where my search failed.)

I would bet that Glohithia is just a misspelled Glochidia
which are larvae of freshwater mussels. Some of them appear to have a snake-like shape.
