Cheiracanthium falcatum

C. falcatum are yellowish brown in color, with a long, slender body and brown maxilla and chelicerae. ^[1] They lack a thoracic furrow. They are distinguished from similar species by a posterior epigyneal depression, copulatory duct coils in three spirals leading downward to the spermatheca in the female vulva, and a finger-like tibial apophysis and long sickle-shaped cymbial spur in the pedipalps of males. They most resemble C. ningmingense but may be distinguished by their thicker tibial apophysis in the male palpus.

C. falcatum are endemic to Taiwan and widely distributed at elevations between 200m and 800m.^[1]
