Summary:SchizopholisWaagen, 1885 is a genus of linguliform brachiopod, which is known from Cambrian Stage 4 to the Wuliuan Stage of Australia, Antarctica, Pakistan and China. Recently, new material of Schizopholis was discovered from the upper part of the Tsinghsutung Formation (Cambrian Series 2, Stage 4) near Balang village, Jianhe County, Guizhou Province, China. These specimens display the oval pedicle opening in the ventral valve, a median tongue and a pair of tubercles in the dorsal valve that are characteristic features of Schizopholis napuru (Kruse, 1990). This is the first time that this species has been described from Guizhou Province, China. Previously, fossils of this species are usually preserved in carbonate deposits, but the new material documented herein preserved in mudstone of the Tsinghsutung Formation, providing new information regarding both the paleogeographic distribution and paleoecology of this species.
