Lyell collected Dictyopyge macrurus (Redfield, 1841) and Philip de Grey Egerton (1806- 1881) described it from the Upper Triassic of Blackstone Mines, Virginia (QJGS, 1847, 3: 261-280). As Lyell figured the specimen in the same paper, it was considered the holotype (Brough, 1931: p. 270). 66 years after this publication the Keeper of Geology at that time at the NHM, Arthur Smith Woodward asked for the type specimen of this species to Leonard Lyell just in case it was left in Kinnordy. Leonard Lyell found one blackleaded specimen of Dictyopyge macrurus that was still in the house making the function of doorstop in the kitchen for more than 66 years! This specimen was cleaned and incorporated in the NHM fossil collections. Currently the lectotype of this species is a specimen (YPM 3207) collected also by William C. Redfield (1789-1857) prior to 1841 from a coal mine in Chesterfield County, Virginia (USA) and kept at the Yale Peabody Museum of Natural History, in New Haven, Connecticut (USA) (Schaeffer & McDonald, 1978: p. 144).
