DistributionIndonesia (Roti Island)

roteensis: type locality: from Lake Enduy, eastern Rote Island, Indonesia.

timorlestensis: area of Lake Iralalaro in Lautém District near the eastern tip of Timor-Leste (East Timor)

timoriensis: East Timor (previously Indonesia); type locality: swamps of Lake Ira Lalaro, East Timor.  
Reproductionoviparous. 
TypesHolotype: MCZ 176730
Holotype: AMNH 160132 [roteensis]
Holotype: WAM R165888 [timorlestensis]
Holotype: AMNH 160135: a juvenile [timorensis] 
Diagnosis 
CommentThis is one of the most endangered turtle species according to a 2003 assessment by the IUCN.

Subspecies: Chelodina mccordi timorlestensis is intermediate between C. m. mccordi from Roti and Chelodina novaeguineae from the island of New Guinea, but, in supporting its subspecific taxonomic status, the new taxon shows more similarities to the nominate form than to C. novaeguineae. Kehlmair et al. 2019 suggested to synonymize roteensis with mccordi.

Habitat: freshwater (rivers, swamps)

NCBI taxonID: 2804320 [Chelodina mccordi timorensis] 
EtymologyNamed after Dr. William Patrick McCord (b. 1950), a veterinary surgeon and a turtle specialist. He owns the East Fishkill Animal Hospital in New York State.
