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.
