Tagiades menaka kotoshona Sonan, 1936

Zephyrus 6:212.

Labels: “ Tagiades / menaka / kotoshoana Sonan DET. J. SONAN,” “ Kotosho/ 10 III – 14 IV 1920 / J. Sonan/ Col. T. Okuni,” “ No. 51,” “ Type [in red].”

A single male specimen was designated as the holotype in the original description and the specimen bearing the type label matches the description (Fig. 7–9). Evans (1949) listed kotoshona as a synonym of T. litigiosa litigiosa Möschler, 1878 . Again, no reason was given. Umeno (1937) pointed out that no diagnostic features could be identified between kotoshona and “ Tagiades menaka martinus Pätz [sic].” Shirôzu (1943) subsequently treated kotoshona as a synonym of T. trebellius martinus Plötz, 1884 . This treatment was followed by subsequent authors (e. g. Shirôzu 1960; Chiba et al. 1992; Tsukiyama et al. 1997). The type shows the characteristics of T. trebellius martinus, which is the only Tagiades found in Kotosho (= Lanyu) (Shirôzu 1960, Yamanaka 1980), a small island off the southeastern coast of Taiwan. Neither T. menaka Moore, 1865 nor litigiosa has been confirmed from Taiwan (Chiba et al. 1992). The name kotoshona Sonan, 1936 is regarded as a junior subjective synonym of T. trebellius martinus Plötz, 1884 in the present study.
