Key to the Japanese species of Stalix View in CoL
Diagnostic characters of Stalix histrio View in CoL Jordan & Snyder, 1902, Stalix immaculata Xu & Zhan, 1980 View in CoL , and S. toyoshio View in CoL are based on comparative material examined and the following literature descriptions: Smith-Vaniz (1989), Shinohara (1999, 2006), Aizawa and Doiuchi (2013), and Allen and Erdmann (2024). Oh et al. (2008) reported a single specimen of Stalix View in CoL from Korea as S. toyoshio View in CoL with detailed description, but this specimen differs from S. toyoshio View in CoL described by Shinohara (1999) in the characteristics of the mandibular pores, the position of the lateral line termination, and the fresh coloration of the body surface. In addition, since there are no nominal species that clearly match the specimen reported by Oh et al. (2008), it is considered an undescribed species and Oh et al. (2008) is not referenced in present key.
