I think this little guy is some sort of Roboastra...perhaps a variation on the Roboastra arika (this one does not have the yellow spot/line in the middle of his head as all other photos I could find, but does have the rest of the markings) or on the Roboastra luteolineolata (the one on medslugs.de looks quite similar in the head but the body/tail is a bit different).
Any ideas?
