Mytharc stands for "mythology arc" and refers to the central storyline of a series. The term was coined by the creators of The X-Files and was used by fans when discussing elements that were part of that central storyline. Episodes that dealt with those elements or introduced a new piece of the puzzle were called "mytharc episodes." The two-parters Colony/Endgame and Tunguska/Terma are considered mytharc episodes because they are part of the bigger picture and not just a MOTW.
Since then the term "mytharc" has been adopted by many fandoms, e.g. in Supernatural fandom for the central demon storyline.
