Citharoceps fidicina
Citharoceps fidicina is a tube-dwelling spider in the family Segestriidae, described by Chamberlin in 1924. The genus Citharoceps is endemic to the southwestern United States and Mexico. Segestriid spiders are characterized by their elongated, cylindrical abdomens and their habit of constructing silken retreats in crevices, under bark, or in other sheltered locations. Members of this family possess six eyes arranged in a distinctive semicircular pattern, a trait that distinguishes them from most other spider families which typically have eight eyes.

The species is native to the United States, with its common name suggesting association with the Big Bend region of Texas. Like other members of the genus Loxosceles, it possesses cytotoxic venom that can cause tissue necrosis in humans, though documented cases specific to this species are limited.

Like other members of its genus, it possesses the distinctive spitting predatory behavior that characterizes this family, using modified venom glands to eject sticky silk-glue mixtures to immobilize prey. The species is part of a group of spiders that are frequently associated with human habitations in their known range. Specific details about its biology remain limited in published literature.
