Plesiosiro is an extinct arachnid genus known exclusively from nine specimens from the Upper Carboniferous of Coseley, Staffordshire, United Kingdom.[1][2] The genus is monotypic, represented only by the species Plesiosiro madeleyi described by Reginald Innes Pocock in his important 1911 monograph on British Carboniferous arachnids. It is the only known member of the order Haptopoda.[3]

The original fossils have been redescribed in detail by Alexander Petrunkevitch in 1949[4] and Dunlop in 1999.[2] A supposed example from the Coal Measures of Lancashire is a misidentification.[2]
