Diagnosis. The new nominate subspecies is distinguished by the minor body size, narrow file, and less number of teeth of file (see measurements in Tables 5–6).

Notes. Walker (1869) described the species Decticus tenebrosus for one female specimen collected from Philippine Island in Mr. Cuming’s collection and one female specimen collected from Korea presented by Capt. Sir E. Belcher, which were deposited in BHNM, London. After examining types, we partly agreed with Storozhenko & Paik’s action (2007) that they designated the female specimen from Philippine Island as a lectotype of M. tenebrosus ( Walker, 1869) . Nonetheless, the latter Korean specimen differs from the Philippine specimen by the minor size, the tegminal shape, length and shape of ovipositor, and etc.. Those special features make it conspecific to the current subspecies.

Distribution. Japan, Korea, Central China, and South China except Yunnan Province (Fig. 14).

Etymology. The subspecies name indicates its minor body size.
