Scytodes zapatana
Gertsch & Mulaik, 1940
Zapatana Spitting Spider
Scytodes zapatana is a of spitting in the Scytodidae, first described by Gertsch and Mulaik in 1940. Like other members of its , it possesses the distinctive spitting predatory that characterizes this family, using modified glands to eject sticky -glue mixtures to immobilize . 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.

Identification
As a Scytodes , S. zapatana can be recognized by the highly convex, dome-shaped that accommodates enlarged glands—this distinguishes spitting from superficially similar like cellar spiders (Pholcidae) or spiders (Sicariidae). Scytodes species have six arranged in three pairs (a triad pattern), rather than the typical eight eyes of most spiders. The species-level identification of S. zapatana requires examination of genitalic structures, as external is highly conserved within the .
Habitat
Associated with human habitations, based on -level patterns. Specific microhabitat preferences for S. zapatana are not documented.
Distribution
USA; distribution records indicate occurrence within the United States. Specific state-level distribution is not clearly documented in available sources.
Human Relevance
Members of the Scytodes are frequently found in and around human dwellings, where they may contribute to control of small . They are not considered dangerous to humans, though they possess unique defensive and predatory capabilities.
Similar Taxa
- Scytodes thoracicaThe most widely distributed North spitting , distinguished by markings and smaller body size (females 4-6 mm); S. zapatana requires genitalic examination for definitive separation
- Loxosceles species (brown spiders)Superficially similar six-eyed arrangement and body form, but distinguished by the convex of Scytodes and the presence of a potential violin-shaped marking on the cephalothorax in Loxosceles; spitting lack the dangerous of sicariids
- Pholcus phalangioides (cellar spiders)Similar long-legged, sprawling appearance and web-building in some Scytodes , but distinguished by eight , different eye arrangement, and highly convex in Scytodes
