I was going to respond to the original post and correct the notion that West African crocs Crocodylus suchus are a rarity as I read the thread before the weekend. You just beat me to it!

The sample was actually 18 individuals (with 2 scored as unknowns Ellen Trout Zoo and 1 as a true Crocodylus niloticus at St. Augustine) out of a random sample "Nile crocodiles" in US zoos. This underlines the importance to research the entire US stocks of "Nile crocodiles" and sort these out.

BTW: West African crocs Crocodylus suchus have been found to occur in Uganda - Kidepo National Park and Awash National Park in Ethiopia too!

Another interesting cline would be Madagascan crocs.

This is a very interesting study! Thanks for sharing. At first I was a bit skeptical of its usefulness when I saw they only recognize three species of Osteolaemus when it's been known for some years now that at least five to seven species exist, isolated within different river systems. However, I am happy to see that they do recognize a difference between the West African I and West African II animals. The majority of captive dwarf crocs have been assumed to be West African II so it's good to see the genetic testing back this up. My concern, however, comes from the range they offer for tetraspis. The map they provide gives tetraspis a range which covered that of at least two different taxa (The Nigerian-Cameroon population and the western Central African/Gabon population, which is true tetraspis). The EAZA testing results I've seen separate these two and have found some individuals of both in European zoos. Realistically, the US population probably consists of true tetraspis due to the ease of obtaining animals from that range compared to that of Nigeria, but without the study recognizing the existing of the two separate populations, this identification is tentative at best.

What surprises me, though, is the absence of osborni at St. Augustine. The individual in question was identified as such by the zoo and I was told as much by the curator of reptiles there following my 2014 visit. The individual I photographed is known to be different (at least morphologically) from all of the zoo's other dwarf crocodiles, which evidently are a mix of "tetraspis" and hybrids. Perhaps the individual in question has died and therefore was not included in the study?

Dissecting the information (hopefully correctly):
-0.0.9 "O. tetraspis" at St. Augustine
-0.0.1 O. sp. West African II at St. Augustine
-0.0.3 hybrids at St. Augustine
-0.0.2 "O. tetraspis" at Woodland Park Zoo
-0.0.1 O. sp. West African II at Lincoln Park Zoo
-0.0.5 hybrids at Lincoln Park Zoo
-0.0.2 O. sp. West African II at Clyde Peeling's Reptiland
-0.0.2 "O. tetraspis" at Fort Worth Zoo
-0.0.4 "O. tetraspis" at Philadelphia Zoo
-0.0.1 "O. tetraspis" at Ellen Trout Zoo
-0.0.1 "O. tetraspis" at Memphis Zoo
-0.0.1 O. sp. West African II at Memphis Zoo

On top of the C. suchus animals @nczoofan listed above, an actual C. niloticus was also identified at St. Augustine, and what I assume is Ellen Trout Zoo has 0.0.2 still unknown animals.

I'm confused as to where the study got "13 as O. sp. nov. cf. tetraspis" from, I'm only counting five animals. Unless I'm incorrect in thinking that animals with different species identifications in their COI lineage and nuclear lineage are hybrids?

EDIT: I do see the presence of one pure West African II at St. Augustine. Maybe this is the animal in question? I still find it bizarre that the zoo would suspect it to be so different and special enough to be tentatively identified as osborni if it's the same as much of the rest of the population.

Also is this an error on their website? It says the words American crocodile?

Yes, the animal you saw would be suchus. They were identified as suchus back when they still had two animals around 2014/2015, though I don't think the signage was updated for a while.

As for new additions to the thread: the website is sort of hard to read so I'm not sure if these are the actual species held here but it seems MOTE Marine Laboratory & Aquarium have American Alligator, Spectacled Caiman, American Crocodile, and Nile Crocodile.

Alligator Alley in WI also has New Guinea croc, 2 caiman species, possibly other croc species? Alligators, Crocodiles and Caimans - Alligator Alley Adventures

Crocodile Encounter in TX has American alligator, Orinoco croc, Siamese croc, and Nile croc (east african, south african, and madagascar)

Asterisks have other species but I'm not sure which.

St. Augustine currently only has halli. They’ve had novaeguineae in the past. Reptile Lagoon’s is, I believe, novaeguineae. I haven’t seen a pic of Alligator Alley’s anytime recently but it seems they don’t have it anymore anyways.

How do we know they only have halli? The paper describing the species says they had both.

I'm not 100% sure on this, but I don't think the Philadelphia zoo has Chinese or American Alligators. I can confirm, however, that they do have West African Crocodiles. The Brandywine Zoo also doesn't have American Alligators. They only had them for one summer.
 
Blank Park Zoo has Cuiver's dwarf caimans last time I checked. I believe they might have an American alligator in the education dpt.

I do believe their original individual Chinese alligator was sent on breeding loan to another zoo.
It seems though that they might have taken in others ...
