Second lieutenant
In Anglophone armies the rank is generally called Second lieutenant except in naval usage, where ensign or sub-lieutenant are used, and in a few cases where the archaic infantry rank of ensign is retained for historic reasons, viz. Canadian household regiments. In former times, the English-language equivalent rank to the cavalry "anthipilarchos" would have been cornet, which is still used as an internal form of adddress for a second lieutenant in the Household Cavalry and Queen's Royal Hussars.
