Why is the mole cricket endangered?

Only the Northern Marsupial Mole is endangered. This was not true until it was separated from the Southern Marsupial Mole as a separate species a few years ago. (Analogy: If there were one million members of a species, then it would not be endangered. But if scientists decided to divide the species into ten thousand different species based on small differences, then each new species would have only one hundred members and would be considered seriously endangered.)
