Type specimens. USNM 62703 About USNM , USNM 62705 About USNM , and USNM 62707 About USNM , cotypes .

Occurrence. Stephen Formation, Mount Bosworth and Mount Stephen, British Columbia; Mount Cap Formation, Northwest Territories; Chisholm Formation, Half Moon Mine, Pioche, Nevada; Bright Angel Formation, Grand Canyon, Arizona; all Glossopleura Assemblage Biozone , Glossopleura boccar Interval Biozone (Morgan, 2021) , (Wuliuan, Miaolingian).

Material examined. USNM 62703, USNM 62702, USNM 62705, USNM 62707, USNM 62713, USNM 62714, USNM 108592a, USNM 108592b, USNM 108592c, SGDS 1973–1976.

Remarks. This is the type species of the genus Glossopleura , and although it has not been identified in the Cadiz Formation , it is close in form to G. mohavensis except for having longer eyes and only seven thoracic segments.

Morgan (2021) proposed restricting Glossopleura boccar to USNM 62703 as a lectotype and USNM 62705 as a syntype / paratype, with USNM 62707 as a hypotype of G. walcotti .
