They do not have run-off vote of any sort and do not appear on the list because their prime-minister is chosen by the parliament. There is no need for run off vote for parliament because they are chosen by popular vote not electoral vote
In India and UK the Prime Minister is at first glance chosen by popular vote and not electoral vote.
-- in a way even in India and UK it is electoral votes which select the PM and not popular vote.
Let us say there are 530 seats and a party has secured 300 seats by popular vote. The MPs who won those seats (Members of Parliament of each party) will meet and select a leader of Parliamentary Party -- who in case of the ruling party will be the PM; usually this choice is known before election but not always.
Now suppose the PM earns dislike of his party or dies -- a new PM can be selected by MPs. Thus there is after all electoral vote even in Westminster system.
And I have an example for you -- Indian general elections in 2004; Congress Party came to power after projecting Sonia Gandhi as PM candidate; but after her party won she decided that it would be preferable to have a quiet economist Dr Manmohan Singh (who was not a MP elected by popular vote) as PM. Did Indians vote for Dr Manmohan Singh as PM .. no .. did they get him as PM .. yes .. did Indians who voted have any say in the matter .. no.
As far as I know same is possible in UK too. But these nations are marked in red in your map.
My example with UK and India is also followed by Germany and Japan. Thus what you said is not correct.
In probably every country at end of the day it is electoral votes which matter in the final count regardless of the manner in which elections are held.
While it seems in UK, Prime Minister is elected by popular vote and in US, President has been elected by electoral votes .. in actuality the Prime Minister of UK rules as long he has confidence of his MPs (electoral votes) and he maybe replaced without calling for fresh elections (of course a new cabinet will have to be sworn in also) if his opponents in the party are sufficiently unified (at least in theory it is possible).
