Yunohamella varietas sp. n., from Ulsan Metropolitan City, Korea is newly described based on the male. The new species is closely related to Yunohamella lyrica (Walckenaer, 1841) and Yunohamella serpatusa (Guan and Zhu in Zhu et al., 1993), but can be distinguished from Y. lyrica and Y. serpatusa by the dorsal pattern of the abdomen, shape of embolus, conductor and median apophysis. The new species was collected with a sweep net in rice fields.
