Abstract
Type is most significant material for taxonomy. Type information is the elementary for taxonomic research. However, some errors often exist in the type citaion or designation on account of typographical error or some other inadvertent negligence (Yang & Wiersema 2006, Weston & Woods 2013, Wang et al. 2015, Yuan & Yang 2016, Sun et al. 2016). It is necessary to rectify type error, not only confirming the author original intention, but also avoiding spreading wrong information to others.
