(type species: Phrurolithus coreanus Paik, 1991 , by original designation).

Diagnosis. This genus can be distinguished from the other phrurolithid genera by femora I–II lacking prolateral spines, the furcated retrolateral tibial apophysis, and the embolus and conductor contiguous to each other in the male palp; the female epigyne has anteriorly situated copulatory openings and the pair of membranous bursae is smaller than in other genera.

Description. Small spiders. Carapace black, smooth, widest at coxae II and III. Chelicerae with three promarginal and two retromarginal teeth, with one or two (one long and another short) spine anteriorly. Femora I–II with one dorsal spine but without prolateral spine; tibia I–II usually with unpaired ventral spines; metatarsus I usually with four pairs of ventral spines, metatarsus II usually with four proventral spines and three retroventral spines. Abdomen oval, without distinct chevron stripes in dorsal view, with large dorsal scutum in males, absent in female. Male palp: femur only somewhat swollen; tibia with two large retrolateral apophyses; tegulum with conspicuous apophysis; embolus long, conductor membranous, contiguous to each other. Female epigyne: epigynal plate with pair of copulatory openings situated anteriorly; copulatory ducts long; spermathecae round and situated posteriorly.
