See Tu and Hormiga (2011) for a detailed description of genitalia.
Remarks.
Species endemic to the island of Taiwan (Fig. 13). As far as we know, this species was previously recorded only from a few specimens collected in the north of the Island. Similarly to the previously mentioned S. longqiensis, S. yangmingshana is widespread across Taiwan and both species share the same habitat. In the original description by Tu and Hormiga (2011), the coordinates of the type locality are incorrectly reported and refer to the type locality of S. longqiensis. Additionally, in their distribution map, Tu and Hormiga (2011: 517) erroneously report the type locality as being in central Taiwan, while it is located in the north of the island. They also mention that the original male holotype was dried out and could not be properly measured thus limiting their description to the genitalia. Accordingly, here we redescribe the habitus of both male and female of this species reporting the related measurements.
