Tetrabothrus japonicus NAKANE, 1991

Tetrabothrus vietnamiculus PACE, 2013: 375 ; nov.syn.

Pace Collection / Tetrabothrus vietnamiculus n. sp., det. R. Pace 2012 / Holotypus Tetrabothrus vietnamiculus mihi, det. R. Pace 2012 / Tetrabothrus japonicus Nakane , det. V. Assing 2015" ( NME).

A d d i t i o n a l m a t e r i a l e x a m i n e d: Vietnam: 13, Cao Bang province, 12 km NE Cao Bang, 22°46'N, 106°19'E, 600-700 m, 15.-16.V.2010, leg. Dembický (NHMB).

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 .
