Clemmys guttata (Schneider 1792): Etymology

In this website I found the etymology of the name Clemmys guttata. It says that Clemmys comes from the greek Klemmys (tortoise) and guttata from the latin gutta (gout)

Regarding Klemmys I coudn't find anything else, but regarding gutta, I found this interesting site

Interesting the botanic use of the word guttate for a leave with spots that look like water drops 

And looking for the origin of words, I wondered who was the Schneider that described Clemmys guttata for the first time in 1792. It was   Johann Gottlob Theaenus Schneider

But Schneider classified Clemmys guttata as Testudo gutatta. According to wikipedia the genus  Clemmys appeared in 1828 thanks to  Ferdinand August Maria Franz von Ritgen

It is also interesting the etymology of the word tortoise. Tortoise comes from latin tartaruchus that comes from the greek tartaroukös. Tartaroukös comes from Tartaros (hell) and Ekhein (inhabitant). People saw tortoises coming from underground or the mud of a pond and decided to call them creatures from hell, maybe not exactly a devil but anything good.
