FIGURE 1. A in The freshwater ostracod (Crustacea) genus Notodromas Lilljeborg, 1853 (Notodromadidae) from Japan; taxonomy, ecology and lifestyle

FIGURE 1. A. Map of localities where Notodromas has been reported in eastern Asia. Data from Brehm (1923; 1933); Chen (1982); Deb (1984); Klie (1938); Martens (1991); Mischke et al. (2002); Neale (1984); Neale & Zhao (1991); Okubo & Ida (1989); Okubo (2003); Pietrzeniuk (1977); Sars (1903); Schornikov (2004); Schornikov (1995); Zenina & Schornikov (2008); Zhao (1990). *1: Reported as N. monacha by Schornikov (1995), but considered to be N. sinensis by Schornikov & Trebukhova (2001). *2: Reported as N. monacha, but because only one juvenile was recovered (Pietrzeniuk 1977), it is considered to be in open nomenclature herein; see text for more details. *3: Bronshtein (1947) reported N. monacha from Kazakhstan, but as no specific localities were given, point is approximate. *4: Sub-fossil occurrence (Mischke et al. 2002). *5: Sars (1903) raised specimens of N. oculata from mud collected from Sumatra, but didn't specify which of two possibly localities the mud was collected from. Point is therefore approximate. N.B. Bronshtein (1947) reported N. monacha from "Western Siberia", but no specific localities were provided. All Japanese records of N. monacha are considered to be Notodromas trulla n. sp. herein. B. Localities where Notodromas trulla n. sp. has been collected. Numbers correspond to those in Table 1. Locality 3 is approximate, as no specific locality data was given. Note that some older records did not give any locality data.
