The latest fieldworks in the Krabi Basin from Thailand have provided accura
te stratigraphic, magnetostratigraphic and faunal settings. A complete left
maxilla of a new baluchimyine rodent, Baluchimys krabiense nov, sp., descr
ibed herein, has been found in the Bang Mark pit from the Krabi mine for wh
ich a Late Eocene age is attributed. The discovery of such an Eocene baluch
imyine in South Asia casts serious doubts on the previous Early Miocene age
assignment for Pakistani baluchimyines. Moreover, the comparison with a La
te Eocene taxa from North Africa allows us to suggest close phylogenetic re
lationships, implying that this group had a widespread African-Asian distri
bution during the Palaeogene. In that context, the endemism assumption rela
ted to the Indian Subcontinent isolation throughout the Eocene until the Ea
rly Miocene is refuted here. (C) 2000 Academie des sciences / Editions scie
