Terrestricythere ivanovae Schornikov, 1969


Terrestricythere ivanovae Schornikov, 1969  

( Figure 11A–C View Figure 11 )


The adult male and two juvenile specimens of Terrestricythere ivanovae   recovered were all in a badly preserved state, indicating that they were probably deceased when collected. Although unlikely, we cannot rule out that they may have been transported into the cave by natural or artificial means after death.

The superfamily Terrestricytheroidea   consists of only five described species, known from the Russian Far East ( Schornikov 1969, 1980) the Black Sea ( Schornikov and Syrtlanova 2008), the UK ( Horne et al. 2004), France ( Scharf and Keyser 1991) and Japan ( Hiruta et al. 2007). The shape of the Korean adult male specimen’ s carapace, seventh limb and hemipenis, although poorly preserved, closely match those of T. ivanovae   ( Figure 11A–C View Figure 11 ).

Three previous reports of T. ivanovae   exist, from the far-east of Russia (two localities), and France ( Schornikov 1969, 1980; Scharf and Keyser 1991). The Russian specimens were recovered from amongst small pebbles kept moist by mist, rain and sea spray, and supralittoral salt-tolerant plants and littoral filamentous algae. The French specimens were recovered from a freshwater lake. The Korean specimens were recovered from freshwater pools in two coastal caves (locality 1), which drain into the nearby seashore through a brooklet.
