Distribution. China ( Hebei, Beijing, Shandong, Henan, Shaanxi, Zhejiang, Sichuan, Guizhou, Yunnan, Hubei, Guangxi, Fujian); South and North Korea, Japan, Philippines ( Rozkošný et al., 2010).

Remarks. This species is very similar to S. spinipes externally but has conspicuously different male terminalia. As for non-genitalic characters, Rozkošný et al. (2010) described in detailed the differences between S. noteoi and S. spinipes .

Steyskal (1980) mentioned in his original description that the hind tibia is yellow with brown rings in the middle and apical portions. We examined 140 specimens ( 83 males, 57 females) of S. noteoi and found that nearly all specimens had brown rings in the hind tibia. Thus we consider this character to be a constant and useful one in part because the hind tibia of the similar S. spinipes is concolorous yellow and lacks brown rings; thus this can be used to easily separate the two species, as shown in couplet 7 in the key.
