EC0B522DFFD7FE59FF4EFB6B3972FA00.taxon	discussion	Comments. Detailed descriptions are provided by Satô (1976) and Takahashi (2003), but they should be partially modified due to the discovery of Y. nishimotoi sp. nov. so that the head and pronotum are sometimes entirely blackish brown. For identification from related (sub) genera, see the key provided by Yang & Yang (2010). Yukikoa can also be distinguished from Themus in the basad constricted male genitalia.	en	Nakamura, Ryo, Kubota, Kôhei (2023): Taxonomic study of the Japanese endemic genus Yukikoa M.

EC0B522DFFD2FE5DFF4EFBC23AF8FE28.taxon	diagnosis	Differential diagnosis. Yukikoa nishimotoi sp. nov. is readily distinguishable from all the congeners by blackcoloured head and pronotum. Though the dorsal plate of male genitalia is similar to those of Y. masatakai Takahashi, 2003 from Nagano Pref. and Y. wittmeri (Nakane, 1963) from Ôsaka Pref., the new species differs from them by longer elytra (EL / MEW> 2.0, EL / HEW> 2.7 in Y. nishimotoi; EL / MEW <1.9, EL / HEW <2.6 in Y. wittmeri and Y. masatakai).	en	Nakamura, Ryo, Kubota, Kôhei (2023): Taxonomic study of the Japanese endemic genus Yukikoa M.
