摘要：A new galeaspid genus, which has been excavated from Bobai,  southeastern Guangxi,  is described in  the  present  paper.  The fossil-bearing  strata  consist  mainly of pale silty mudstone and greyish  sandstone,  yielding  abundant fishes (Guangsipetalichthys bobaiensis, Bothriolepis sp., Hunanolepis tieni, sinolepids, sarcopterygians,etc.)and  some  invertebrates.  According to the  associated  placoderms,  the  new galeaspid is regarded as Middle  Devonian in age.  It is the first convincing  record of the Middle Devonian  galeaspids in China, thus has an important  biostratigraphic and biogeographic significance.
