The distribution pattern of Pholcus phungiformes species-group indicates that, in Jilin and Heilongjiang, China and North Korea, additional species diversity remains undiscovered.
Pholcus maxian sp. nov., one new species of P. phungiformes species-group, is described, based on material collected from the borderline between Jilin, China and North Korea. It represents the fifth endemic species of this species-group and the genus Pholcus from this region.

The genus Pholcus Walckenaer, 1805 belongs to the family Pholcidae C.L. Koch, 1850, is diverse and currently contains 95 genera and 1,842 species (
Specimens were examined and measured with a Leica M205 C stereomicroscope. The left male pedipalp was photographed. External female genitalia were photographed before the dissection. Vulva was previously treated in a 10% warm solution of potassium hydroxide (KOH) to dissolve soft tissues before illustration. Images were captured with a Canon EOS 750D wide zoom digital camera (24.2 megapixels) mounted on the stereomicroscope mentioned above and assembled using Helicon Focus 3.10.3 image stacking software (
