Justification for delineation
For Southeast Asia, delineations were determined using a bottom-up approach that employed both published and unpublished field data and expert assessment (Abell et al. 2008). The fauna differs from surrounding ecoregions and includes the oldest known fauna in this region (M. Kottelat pers. comm. 2006).
