C o m m e n t: The original description of Tetrabothrus vietnamiculus is based on a unique male from Vietnam ( PACE 2013 ). The external and male sexual characters of the holotype (see also the figures in the original description) are identical to those illustrated for T. japonicus by YAN & LI (2015b) for T. japonicus . According to MARUYAMA (email, 24.IX.2015 ), the interpretation of T. japonicus in YAN & LI (2015b) is correct. Consequently, T. vietnamiculus is placed in synonymy with T. japonicus .
