Type material.

Holotype ♀ and paratype 4♀ (NHMSU-TW03), China: Taiwan Province, Nantou County, Huisun Forest Farm (24°05.279'N, 121°02.078'E; 788 m elev.), 1.VII.2013, G. Zheng leg.

Etymology.

The specific name is derived from the type locality; noun in apposition.

Diagnosis.

This new species differs from other species except for M. gongi, M. ogatai, and M. yinae by the nearly spherical spermathecae and having a small scape rather than a long, soft, membranous one (cf. Figs 10E, F, 13C, 14F, 17C). It can be distinguished from M. gongi, M. ogatai, and M. yinae by the nearly spherical spermathecae and the narrower posterior sclerotized area of copulatory ducts (cf. Figs 10F, 9F, 19H and Ono 2007: fig. 70).
