摘要

Pholcus gosuensis sp. nov. is described from the entrance zone of Gosu cave, Chungchengbuk-do, Korea. The species is characterized by male palpal organs with three expanded apophyses and developed callosity on procursus, two frontal apophyses of chelicerae and degrading appendix, and sclerotized arches on uterus externus. The species is related to P. crassus Paik, 1978 and P. acutulus Paik, 1978 in having identical uncus and embolus but differentiated from those species by the combined characters oflarge apophyses and heavily sclerotized callosity on procursus, and structure of arches on uterus externus.
