Diagnosis. The male palp of F. geumdaensis n. sp. is separated from all other Falcileptoneta species by the tibia with two retrolateral spur­like apophyses on the distal end, the embolus with transparent membrane anterodorsally, the curved spine­like prolateral sclerite of the palpal bulb, and the presence of some microscopic hairs on the retrolateral sclerite of the palpal bulb ( Fig. 1 E­H).
