On August 15th, the zoo announced that a (0.0.1) eastern indigo snake hatched, which is the first time the species has been successfully bred at the facility.

On March 28th, it was announced that the zoo transferred (1.1) American (albino) alligators to the Denver Zoo in Colorado.

On September 23rd, it was announced that the zoo acquired (0.0.2) saltwater crocodiles from Clyde Peeling's Reptiland in Pennsylvania. It was also announced that the zoo transferred (0.0.3) Nile crocodiles to Reptiland.

the zoo announced the first captive hatching in the US of the newly described species of Dwarf Croc (Osteolaemus afzelii). the parents of the babies were confirmed to be pure members of this new species via DNA testing. They mark the 18th species of crocodilian bred at the park.

* I'm personally struggling to find any info about this new species online. Most sources just list O. tetraspis and O. osborni

It's not a valid taxonomic name, that's why :rolleyes::D as far as I can tell, it's a name which the notorious taxonomic vandal Raymond Hoser used within a single cladogram in reference to the as-yet-undescribed West African species complex of Osteolaemus (which last I heard probably represents two distinct taxa, currently referred to as West Africa 1 and West Africa 2 by those researchers attempting to work out which taxa are held in captivity). As Hoser never actually published a description for the species, and it refers to multiple taxa, the name has even less validity than the myriad others he has coined.

Were I to guess, St Augustine has come across the name somewhere online and assumed its the official name for whichever of the West African Dwarf they hold.
 
I new confirmed study is coming out shortly. SAAF is sending out all confirmed hybrids and single O. osborni to stick with pure tetrapis and afzelli. The study is through UF which also confirmed western croc and further confirming the Cataphractus species. Once the African species are genomed they will be moving onto C. acutus to see if the there is different speciation between the Northern and Southern populations, specifically the Jamaican population. C. porosus is also on the agenda

I know the AZA and various crocodile specialist groupings have worked hard to elucidate the status of the 2 different West African taxa. I would assume that O. afzelii may enter the history books upon description of the taxon.

I have great faith in the experts at SAAF and the IUCN Croc Specialist Groups to determine the diversity within the Ostealaemus and Cataphractus complexes and will very shortly attempt their scientific description.

Please take note that the recent separation of New Guinea (or prefererred by my persona to rename these Papua) crocodiles into Crocodylus novaeguineae and Crocodylus halli (in which SAAF played a great role along with experts at th Field Museum of Natural History in Chicago). I expect similar will happen with the African crocodiles....!

I am glad that SAAF is taking a major step in sorting their Osteolaemus and will in future focus solelty on pure-bred O. tetraspis and O. species novum (West Africa - afzelii of which they hold a pair)! Hopefully, other zoos will follow.

I wonder where they shipped off their hybrids and to which zoo or facility they will send the single O. osborni (known if it is male or female?).

AD FINITUM: Is it known how many O. terraspis they maintain (sex, age, breeding prospects)?

afzelii is a valid name, although treated as a synonym of tetraspis. It was originally used in 1867 (as Halcrosia afzelii) to describe a partial specimen from Sierra Leone deposited in a Swedish museum. Presumably this is the oldest available name for one of the new species within the complex - although, if so, there doesn't appear to actually have been any paper published yet so the Alligator Farm's "newly described species" is an inaccurate turn of phrase.

Which would make my latter presumption correct:

...given the fact that as far as I know, no one has yet determined what the range boundaries of the complex species are, and as such which one/s occur in Sierra Leone.

One hopes they're not merely treating all members of the complex as a single species, and they actually do have a pure pairing. I may have to track down photos of the adults and ask around with those better informed than I about the differences between the proposed taxa.
