Taxonomic remarks: Oedothorax khasi sp. nov. is similar to another Oriental species, O. myanmar, recently described from mountains of the Chin State in Myanmar (Tanasevitch, 2017). The new species is clearly distinguished by the shape of the dorsal apophysis on the palpal tibia, as well as by the relatively large and not curved radix.

Distribution: Only known from the type locality in northern India.
