7. Sunda Clouded Leopard (Neofelis diardi)
The forest dependent Sunda Clouded Leopard (Neofelis diardi) occurs on the islands of Borneo and Sumatra and is a sister species to the Mainland Clouded Leopard of Southeast Asia.
Habitat loss due to commercial logging and clearing of forests for oil palm plantations have directly contributed to a population decline of Clouded Leopards of more than 30% in only two decades (1993 - 2014).

Some use the term 'botanical name' however that term is only applicable to the plant kingdom (botany) and not the animal kingdom (zoology).
Subspecies
The clouded leopards on the islands of Sumatra and Borneo were first described in 2006 as Sunda Clouded Leopards when genetic analysis showed sufficient differentiation from Mainland Clouded Leopards.
In addition, the Sumatran and Bornean cats were distinct enough to be described as separate subspecies:
1. Neofelis diardi diardi (Sumatra and Batu islands)
2. Neofelis diardi borneensis (Borneo)
Coat pattern differences between the Mainland and Sunda Clouded Leopards:
Mainland: larger cloud markings with few inner spots
Sunda: smaller cloud markings with many inner spots
