One type rat discovered as new species in Halmahera. The results are revealed in the Zoological Journal of the Linnean Foundation, October 2013 issue. “We call this a new species of mice with Halmaheramys bokimekot,” explained Pierre H. Fabre, from the University of Copenhagen in the study abstract, which is spread on Sunday (22/9/2013).

According to Pierre, this rat species differ from those in North Maluku. The difference obtained after conducting a study in molecular data and morphology. They also try to use DNA gene tracking method, to reduce the possibility of similarities with other types of mice, which live there.

Mice were found remote hilly areas. Bokimekot name is taken from one of the main hill finding the location of a mouse. Mice was initiated by the discovery of joint research between the University of Copenhagen and the Museum Zoologicum Bogoriense Indonesia.

Ktistofer Helgen, of the Smithsonian Institution, Washington DC, United States (US), as well as researchers who also claimed the discovery of the mice of paramount importance. Because not only prove a new species, but also a new genus.

“It seems there will be more new species that can be found in Indonesia, compared to many other regions in the world,” he told the BBC.

The findings were then also considered as one of the main evidence of Wallace’s theory, the existence of zoology line between the western and eastern Indonesia. Separation zone which is then referred to as the Wallacea line separating species of flora and fauna of them.

One of the main animals that prove the existence of such a line of mice newfound Halmahera. Because these mice do not have a pointed line of the same genes with the other rats in Halmahera.
