I've already posted the links to one of the most important document related the organization of the late Roman army (Notitia Dignitatum) but I have seen that these links are appreciated so I decided to insert them in each post I'll write about this matter
The shield pattern in the Oxford version of the Notitia is reported below
|The fourth shield in the fourth line starting from left|
- seniores/iuniores was added to the name of the unit after Diocletian's decision to split the Imperium in two parts and consequently the units
- seniores/iuniores indicated the experience level of the unit.
Under my point of the view I prefer the first explanation. Please consider that the Menapi iuniores were part of Magister Militum per Thracias command.
Some photos of my miniatures are below
The name Menapii derives from a Belgic tribe, in fact it is possible that the unit was enlisted or stationed in Gaul before joining to the field army.
One of the miniature in the second line (a foundry miniature) is equipped with a plumbata mamillata. Below an example of the weapon directly from Notitia Dignitatum
The plumbatae (tribulata and mamillata) started to be used by Romans in 4th century. It is a weapon well described by Vegetio in the De Re Militari (1,17) and by an anonymous in De Rebus Bellicis (10,11). This little dart (around 50 cm) was generally used with the bow to block the enemy advance.
Below a photo very interesting photo that explain as the dart was thrown

The tribune of the photo carries a cavalry shield (may be Equites cetrati iuniores) but it was so nice that I decided to bend the rules.
