A spider of the species Hahnia zhejiangensis (Song & Zheng 1982) has been recorded in Taiwan for the first time. It differs from all other congeners due to the following combination of characteristics: both genders have anterior median eyes smaller than anterior lateral eyes, chelicerae with 2 - 3 promarginal and 5 - 6 retromarginal teeth, a large spiracular opening located in the middle of the epigastric furrow and at the base of the median spinnerets; females possess a pair of dark brown triangular markings and a large copulatory opening on the epigynum, with two vertical dark brown sclerotized plates behind the epigastric furrow; males display retrolateral tibial apophysis of the palpal organ, which is stout and strongly recurved, while the palpal patellar spur is small, curved and single-pointed. Both genders of this species have been redescribed and illustrated based on specimens obtained from Taiwan.
