Holotype: South Korea • ♂; Jeollabuk-do, Buan-gun, Byeonsan-myeon, Docheong-ri , Mohang Beach ; 35°35.0'N, 126°30.3'E, 14 m; 20 July 2022; C.M. Jang & S.T. Kim leg.; NIBR #WGJTIV0000000568 GoogleMaps . Paratypes: South Korea • 2♂♂ and 8♀♀ same data as for holotype; NIBR #NUHGIV00000000022-31 GoogleMaps .
Diagnosis.
Pholcus mohang 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 elliptical, roundly depressed on one side and truncated on the other side (Fig. 5H View Figure 5 ); procursus with pointed prolateral apophysis (numbered 1 in Fig. 5H-J View Figure 5 ), white and slightly curved ventral membranous process (numbered 2 in Fig. 5H, I View Figure 5 ), claw-shaped ventrodistal apophysis (numbered 3 in Fig. 5H, J View Figure 5 ), and roundly depressed dorsodistal apophysis with pointed tips at both ends (numbered 4 in Fig. 5I, J View Figure 5 ). Female - anterior arch procurved with oval pore plates bordering the arch (Fig. 5G View Figure 5 ).
