There so much confusion here
. it would be nice if we had ANY reference for Seleucids.
Some will state that the xyston is itself a doru used on horseback (Heckel)
which makes sense if one compares the the short spears and javelins used by everybody else. The stout nine foot long cornel wood doru would be longer than anything the Greek or Persian cavalry concurrently used, and already had the well described butt spike, often described in action.
Art and other reference seems to make identifying the xyston as longer, and yet there is always the nagging issue of the so-called "lancers" which cause extra confusion because using a 16 foot lance from horseback is kind of silly.
If Arrian is correct that the xyston is the same as a kontos, that causes issues as well since the combats Arrian describes are not what one would expect from a two handed weapon, more of a two headed spear of decent length- so Heckel may be right
.
So if Alexander is using a "lance" on the Alexander mosaic, what are the rest of his cavalry using, overarm like regular hoplite spears?? Also the absent spear on the Alexander Sarcophagus doesn't seem to support a twelve foot kontos and the overarm stance is puzzling
. would anybody use a twelve foot spear overarm-- even on foot? If you look at it, a twelve foot spear would hang out about four or more feet outside the Sarcophagus' edge, which certainly busts the symmetry of the composition.

Now my own website kind of supports the "standard view", but I can be full of

So when I am alowed to guess.. and I am since this is TMP..
My guess is that the Companions probably used a typical hoplite spear
of eight or nine feet long, which the Macedonians called a xyston.
The special lancer units used a longer version based on Thracian influences, which was up to 12 feet long.. this is what is shown being used by Alexander on the mosaic and the unarmored "kinch tomb" rider
over the years this lance may have become what was known as a 'xyston' and this information is what was passed down to us and somehow the 'xyston' became confused as the same thing as a kontos.
The kontos is thicker and heavier (thus the name kontos-barge pole), so it's under handed use is well displayed by the Parthian and later art, as well as specific commentary. This makes sense for such a heavy weapon.
And to be even more cart spilling, I reckon it's tough to find a reference that Parthian cataphracts in the Seleucid campaigns used a kontos like weapon. The reasonable evolutionary backtracking that takes the development of the nomadic armored horseman back to the Skythian Massagetai, doesn't totally infer that longer spears are part of their earlier gear. In fact to do the connections one has to go to descriptions of Gaugamela where it is reported that Darius gave his heavy cavalry longer spears to compete with the Macedonians. Thus the bridge of heavy armored with barding cavalry and longer spear is noted for the first time in 331 BC (by my reckoning).
Now the Parthians being part of the Dahai confederacy would have also witnessed the heavy nomadic neighbors use longer spears, so their innovation may have been to simply copy that. So it's possible that the heavy Parthain cavalry of 200 BC was just barded armored cavalryman with a nine foot spear, and over the next hundred years the spear developed into the heavier kontos???
So how does that answer the question? poorly
I would think a Seleucid cataphract would use a xyston. What is a xyston? Well if you got this far then you can decide on your own.
