As promissed, I wrote some info about the Cavalry:
The Cavalry of the Greek motherland was rather weak compared to it’s colonies in South Italy, the so called Magna Graecia.
While the Ίππε̃ις of Sparta were on foot, the Spartan colony Taras could muster 4000 horsemen (cf. Strab.VI 3,4). Although only few is known about their equipment, there are some coins showing a quite heavy armor.

These are from Kraay: Greek Coins (Pl.108, 312f). Further examples are listed in Arnaldo (ed.): A catalogue of the Greek Coins in the British Museum. Italy, p.185, nr.187-198; p.197, nr.274-277; p.201, nr.306.
We see the muscle couirass with πτέγυρες (‘armored flaps’?), the shield, which seems to smaller than an Argive shield, but it is important to note the two attached spears. The right hand is not good to see, maybe it held a spear to, as many other horsemen of Tarantine coinage do. The helmet is crested and was identified as Attic (cf. Kraay, p.315).
Though all numismatic evidence for Syracuse’s cavalry is from Hellenistic age (Agathokles and Hieron II.), there is other evidence. The most important is from Diodor, who tells us that Dionysios the Tyrant of Syracuse ordered to furnish the infantry officiers and the cavalry with 14.000 (!) breastplates of exceptional beauty and craftmen’s art (cf. Diod. XIV 43,2f).
The Syracusian Cavalry was superior in every aspect to the cavaly mustered by Athens. The comparision in Thukydides (Thuk. VI 20,4; 22,1) reveals this as much as the combat records (cf. Thuk. VI 71,2; 88,6; 101,5; VII 4,6; 6,3; 11,2-4; 78,6; 81,2; 84,2). They even managed to defeat Hoplites (cf. Thuk. VI 70,3), that happened very seldom in the classic era.
The wast superiority is noteworthy as the Athenians did have aquired a good cavalry force themselves this time (cf. Spence: Cavalry of Classical Greece, deals with Athenian cavalry almost exclusively).
The tactics used by the Syracusian riders correspond with the equipment shown by Tarantine mintage. The harrass and skirmish with their spears, seldom going for close combat, only when the enemy is disordered.
Archaeology again is helpful in order to clarify the armor. Since the ‘classic’ muscle cuirass is rather bad for riding due to it’s weight, size and inflexibilty, a better muscle cuirass was developed. It bends outwards over the hips, consequently does not hamper the mobility of the rider. Moreover it is lighter than most of the muscle cuirasses of the Greek motherland (cf. Franz: Unteruchungen zu den Hopliten…, p.118).

The helmets for cavalry should be open faced in order to cope the complex cavalry maneuvers (cf. Xen.Equ. XII 3). Since we have found many Chalcidian Helmets in Magna Greacia, which fits to Xenophons demand, we can assume that this was the helmet used (cf. Snodgrass: Arms and Armor of the Greeks, p.140).
There is absolutly no evidence for shields used by the Syracusian cavalry, but this does not neccessarly means an absence of shields because comparable cavalry did use them. On the other hand, other comparable cavalry did not…
More than noteworthy is the armor of the horses. Since the 6th cent. BC the Greeks in Italy did possess horse armor in form of προμετωπίδια (frontleds ?) and προστερνίδια (breastplates).
These were made of a single bronze plate, unlike later hellenistic horse armor, which was developed under Iranian influence. The Gorgonaion is a very common blazon, while the frontleds probably were decored with feathers like the Italic knights did.

The Greeks in south Italy were the only Greeks, who had used horse armor. A few exemples were found in Olympia and one in Athens, but they originated from Italy for sure (cf. Kunze: 8. Bericht über die Ausgrabungen in Olympia, p.188).
Campanian and Lucanian knights’ horses had very similar equipment, but sometimes the προστερνίδια were only made of linen (cf. Steingräber: Grabmalereien in Unteritalien, Abb.27).
