Apomastus schlingeri
Apomastus schlingeri is a venomous trapdoor spider species described by Bond & Opell in 2002. It was originally misidentified as Aptostichus schlingeri before taxonomic revision placed it in the genus Apomastus. The species is known for producing a complex of neurotoxic peptides called aptotoxins, which function as voltage-gated sodium channel blockers. It is one of only two known species in the genus Apomastus, both restricted to the United States.
