Cephennodes (s. str.) yume Hoshina, 2017 [ Japan: Okinawa Is.]

Two new Chinese species are described below.

Three species described by Hideto Hoshina, C. akane (Taiwan), C. maya (Taiwan), and C. yume ( Japan: Okinawa Is.) cannot be identified based on the original descriptions and illustrations. Judging from highly inadequate figures, C. yume and C. akane can be synonyms. The illustrations, or rather rough sketches of the aedeagus of C. maya are even more problematic. I assign this species to the C. taurus group based on the Hoshina’s (2021) description of the male characters: “Head impressed in anterior part of vertex and bearing a pair of a long upstanding bristlelike structures on posterior part of vertex.” Hoshina stated that C. maya is similar to C. hongkongensis , which clearly demonstrates that he was not familiar with the division of Cephennodes into species groups, because C. hongongensis is not a member of the C. taurus group.
