Diagnosis.
Pholcus yangpyeong sp. nov. can be easily distinguished from the other species within the P. phungiformes species group by the combination of the following characters: Male - uncus rectangular and protruding triangularly on one side; procursus with prolateral apophysis with two pointed and one serrated tips (numbered 1 in Fig. 7H, I View Figure 7 ), strongly curved ventral membranous process (numbered 2 in Fig. 7H, I View Figure 7 ), claw-shaped and slightly curved ventrodistal apophysis (numbered 3 in Fig. 7H-J View Figure 7 ). Female - anterior arch slightly recurved, pore plates rectangular and far apart from each other (Fig. 7G View Figure 7 ).
