''Plectreurys tristis'' (synonym ''Plectreurys bispinosus'' Chamberlin) is a species of venomous spiders commonly known as primitive hunting spiders belonging to a family of plectreurid spiders. They produce a venom that contains a group of insecticidal peptides called plectoxins. They are found in western North America, Central America and Mexico. ==Description==
''Plectreurys tristis'' are large spiders. The adult male can be 12 mm long on its main body, and about 25 mm with legs stretched. The females are still larger in all proportions. The cephalothorax and legs are dark-brown in colour, and have no markings. Unlike other closely related species, the legs are stout and densely hairy, but devoid of the long spines. The body covering, carapace is rough (granulated) and lacks setae. The abdomen is almost rounded and yellowish-grey in colour. The abdominal setae are also similarly coloured. They have eight eyes arranged in two rows.
