The Kai giant rat ( Uromys siebersi ) is a barely researched rodent belonging to the genus of the giant mosaic-tailed rats . The species is only known from one skull and three specimens collected on the Kai Besar Island ( Kai Islands ). The holotype from 1922 is in the Natural History Museum and the paratype in the Museum Zoologicum Bogoriense in Cibinong , Indonesia . There is also another copy in the Museo Civico di Storia Naturale Giacomo Doria in Genoa and a skull in the Museum für Naturkunde , Berlin. It is named after the ornithologist Hendrik Cornelis Siebers .

features

The holotype has a head-trunk length of 280 mm and a tail length of 84 mm. The condylobasal length of the skull is 59.5 mm. The characteristic features of the Kai giant rat are a very short tail, which is more marbled than that of the white-tailed giant rat ( Uromys caudimaculatus ), small crevice-shaped incisor holes and a conspicuously arched skull.

Systematics

The taxonomic status of the Kai giant rat is unclear. In 1923 it was described by Oldfield Thomas as a separate species. Hans Rümmler (1938) and John Reeves Ellerman (1941) classified them as a subspecies of the giant white tailed rat ( Uromys caudimaculatus ). Eleanor MO Laurie and John Edwards Hill synonymized it in 1954 with the subspecies Uromys caudimaculatus aruensis . Tim Flannery and Colin Groves rated the giant Kai rat in their 1994 revision of the genus Uromys as a species with uncertain status, as they could not assign this taxon to any subspecies of the giant white tailed rat. The IUCN classifies the Kai Giant Rat in the category of insufficient data ( data deficient ).
