Cheiracanthium filiapophysium

C. filiapophysium are yellowish brown in color, with a pale grayish brown dorsal cardiac pattern on their abdomens. ^[1] They lack a thoracic furrow. Their chelicerae sport three teeth on both the promargin and retromargin of each fang groove. Males have well-developed palpal bulbs. They most resemble C. torsivum but may be distinguished by their long, thin, and curved cymbial spurs and pear-shaped spermatheca.

The species name "filiapophysium" means "thread-like apophysis, referring to the thin, long, and curved cymbial spur on the male pedipalp. ^[1]
