We propose that these data support identification of a new alphacoronavirus, which has been designated as Mystacina bat CoV/New Zealand/2013.
To be consistent with this estimate, Mystacina bat coronavirus would need to have been introduced to bats on Whenua hou within the past 800 years since humans first arrived on this island (given that the island had no other mammals before this time) (11) or is extant to modern alphacoronavirus phylogenetic radiation (genesis and expansion).
The discovery of Mystacina bat CoV/New Zealand/2013 virus could lend support to such a theory; despite potentially millions of years of isolation, it has diverged relatively little from other extant alphacoronaviruses, as shown by the close relationship of the Rdrp and spike protein genes to those of other extant alphacoronaviruses (Figures 1, 2).
That is why in the common matrix with non-flying mammals it is more reasonable to regard them as using predominantly one medium (Ae/Ae), with a possible exception of bats belonging to the genus Mystacina
, found in New Zealand, which forage both in flight and while crawling on the ground (TAe/Ae) (Nowak, 1991).
