"The morphological characteristics, geographic distribution, habitat, and habits of Rattus losea are presented. The species occurs in grass, scrub, and agricultural habitats of Indochina north of the Isthmus of Kra (lat. 1050'N). Its closest phylogenetic relative is the new species, Rattus osgoodi, known from samples obtained from the Langbian Peak region in southern Vietnam. The morphological and geographic features of R. losea and its relative are contrasted with those of other Indochinese Rattus, namely, R. rattus, R. norvegicus, R. exulans, R. sikkimensis, R. nitidus, R. turkestanicus, R. argentiventer, and R. brunneus. The ricefield rat, R. argentiventer, may be more closely related to R. losea and the new species than to any other species of Indochinese Rattus, a hypothesis that should be tested with other kinds of data. Results presented here are part of a systematic study of native Asian Rattus"--P. [1].
