Wikipedia: “A ‘sailor cap’ is a round, flat visorless hat worn by sailors in many of the world's navies. A tally, an inscribed black silk ribbon, is tied around the base which usually bears the name of a ship or a navy.”
The “Dixie cup” hat you show doesn’t fit this description. (Not flat, no tally.)
Ironically, that picture comes from the Wikipedia article on pith helmets. It seems to be a very broad category, which includes everything from the helmets worn by the British in India to that German "tropenhelm" c. 1910.
I'm not sure I understand the objection. But in any case I changed the picture. The hat looks almost exactly the same, but the Wikipedia article explicitly says that these are pith helmets.
Number 16 looks like a possible pith helmet with a spike on top, and the spike makes it a Pickelhaube or Prussian helmet. Please find one without the spike or allow Prussian.
I think the issue is that a "Pith Helmet" is a method of construction that covers a wide variety of different styles. Most styles of pith helmets do not have a spike. A Pickelhaube (aka Kaizer Helmet, Prussian Helmet, Pickelhelm, Pickel Helmet) is characterized by the spike, although not made of pith.
Pith helmets originaly are safari helmets, just for the sun. Later also used in the military. Even later though still called pith helmets, they werent truely pith helmets, because they didnt use the pith plant anymore. They just contined to use the name.
Though the helmet in pickelhaube style depicted here could be considered a pith helmet. It is not representative in my opinion. just google pith helmet and see what comes up. Those are generally considered pith helmets. (Khaki coloured, made from pith, with airholes)
While the pickelhaube pictured (#16) may be a pith helmet technically, I double-checked that Wikipedia article that the picture came from and found that the spiked and ornamented style is not typical of pith helmets as the majority of the styles shown there are the much simpler non-spiked and non-ornamented safari style that I, PoetsCorner and almightyjosh appear to be more familiar with.
Pork pie hats have a flat top, with just a little indentation around the rim (like a pie crust!). My understanding of Panama hats is that they can be ANY style hat, as long as they are made of Toquila straw.
There is a bunch of names for top hat here, they should all be included, I for instance kept trying cylinder because that's how we call it here in Serbia.
Agree that the brim is somewhat narrow for a fedora - but it's too wide to be a trilby. Also, a trilby would, or should, be noticeably turned down in the front.
Fun how languages work. Sombrero in Spanish is generic for hat, so all the others would actually be some type of sombrero. Then some other language borrows the word and gives it some specificity it doesn't have originally.
I tried Mexican hat for that one, didn't work (that's how we actually call it in Spain).
Tried porkpie hat for the sailor's cap, and of course it was rejected. Another one of those words and terms that sows confusion between English speakers either side of the pond. In British usage a pork pie hat is the Royal Navy sailor's cap, in the US its something different.

A pith helmet is saucer shaped and is designed to protect from the African sun on safari.
Though the helmet in pickelhaube style depicted here could be considered a pith helmet. It is not representative in my opinion. just google pith helmet and see what comes up. Those are generally considered pith helmets. (Khaki coloured, made from pith, with airholes)
Also, I agree with poetscorner about the Pith.
Finally got to level 50!
