本文首次紀錄浙江橫疣蛛在台灣之發現。本種與同屬之其他種類區別特徵如下：前牙堤齒2-3枚，後牙堤齒5-6枚；前中眼黑色，明顯小於前側眼；氣孔開口於胃外溝和中絲疣連線之中點上；雌蛛之外雌器開口於前方，並有一對黑褐色三角片在其兩側，另有一對黑褐色縱長形幾丁質板在胃外溝後緣；雄蛛觸肢之脛節突起巨大且彎曲，末端尖細，膝節突起小、彎曲且末端不分叉。本文並根據台灣標本重新描述及繪圖。

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, chelicerate 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 pigynum, with two vertical dark brown sclerotized plates behined 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.
