Habitat

This species is frequently found inhabiting tombs at hilly gravesites in South Korea (Fig. 2 View Figure 2 A and B). The spider builds a silken tunnel, about 15–20 cm in length, underground in the yellow soil between grasses, such as fine-leaf shae sedges ( Carex humilis var. nana Ohwi ) ( Cyperaceae ) and zoysia grass ( Zoysia japonica Steud ) ( Poaceae ) (Fig. 2 View Figure 2 C). A sheet web is attached above the entrance of the silken tube, which is connected to the ground (Fig. 2 View Figure 2 D and E).

Distribution

Europe, Turkey, Caucasus, Iran, China, South Korea, Russia (to Far East), Central Asia ( World Spider Catalog 2025).
