did a quick research on wiki
The Seleucid cavalry, after the introduction of the Cataphract, can be sub-divided into several categories. Firstly, there were the heavy cavalry of which there were Kataphraktoi (armoured) and Aphraktoi (unarmoured). The Aphraktoi were divided into two groups, lancer and missile troops. The lancers, who performed the job of heavy cavalry before the Cataphract, were known by numerous names, for example dorataphoroi, sarissaphoroi, kontophoroi, xystophoroi and lonchophoroi.
Xystophoroi and lonchophoroi were mentioned specifically by Titus Flamininus whilst in discussion with the Achaeans.[33] The light cavalry was used to skirmish, so troops such as those that fought in the Tarentine style were common within this category, although there were numerous native contingents too.
when reading this i think there where several type of spears used by cav.but what spear the lonchoporoi used is not clear.probably a spear like the dory
@Ownager don't need to correct you,if it's in EB it's the truth
The kontos (Greek: κοντός) was the Greek name for a type of long wooden cavalry lance used by Iranian, especially Achaemenid successors' cavalry, most notably cataphracts.
