Long-tailed armored tree-rat
The long-tailed armored tree-rat, "Makalata macrura", is a spiny rat species from South America. It is found in Brazil, with a population in Ecuador which is referable either to this species or to "Makalata didelphoides". Initially considered a large form of the latter species, it actually represents a distinct species as supported by morphological and molecular characters. The etymology of the species name derives from the two ancient greek words (), meaning "long", and (), meaning "animal tail".
