Abstract
A new species of the spider genus Heptathela belonging to the family Liphistiidae is described from Tam Dao, northern Vietnam under the name of Heptathela tomokunii sp. nov. The spiders of the species built retreats with a trapdoor typical for the Heptathelinae. A close relationship is recognized between this new species and Heptathela tonkinensis (BRISTOWE, 1933) described from the area of Song Luc Nam, about 100km east of the type locality of the new species.
