If you are writing for a general audience (even an general academic audience) you should avoid using in-group jargon without explanations. Overloading your audience with words they do not understand will not help you achieve your purpose.
Genus. Myrmecobius. The numbat is a small carnivorous marsupial from Australia, and the only member of the family Myrmecobiidae. It is a specialised termite-eater and is easily recognised by its slender, graceful body and short, stiff hair which is reddish-brown with black and white stripes across its back and rump.
A very few species (the numbats) have no pouches -- young fuse to nipples and cling to their mothers' fur. Some species become pregnant soon after one baby enters the pouch. The second baby stays in a dormant intrauterine stage until baby No. 1 begins venturing into the outside world.
