149 Notes: Study of the Holotype of C. (A.) touzalini Andrewes, 1920 and of the Holotype and of new material of C. (Amblygenius) cebuensis Kirschenhofer, 2008 , described from Cebu and Luzon, showed no differences, both in the external

( Figs 9-11 View Figs 9-11 ) and the aedeagal ( Figs 12-14 View Figs 12-14 ) characters, proving that the two taxa are conspecific. Anyway, Jedlička (1959) had already mentioned this species for the Philippines. We therefore propose the new synonymy: C. (A.) cebuensis Kirschenhofer, 2008 = Chlaenius (Amblygenius) touzalini Andrewes, 1920 syn. n..

The group of species which this one belongs to includes several species of very homogeneous aspect and very difficult to distinguish, diffused in East Asia, from India and Nepal to Japan. Jedlicka (1959)

150 provides a key for the determination of the 9 species known at that time, not mentioning the subgenus they should be included in. Kirschenhofer (2004) provides a more complete key, including the 12 species described until that moment, but seems to consider them as belonging to Chlaenius s. str. We prefer to keep these species within the subgenus Amblygenius , as is the most traditional subgeneric assignment.

Distribution. C. (Amblygenius) touzalini Andrewes, 1920 was described from South Korea (Jeju island), and later cited for China, North Korea, Thailand, Taiwan and Vietnam ( Anichtchenko, 2024). In the Philippines it is known from Cebu, Luzon, Mindanao and Samar Islands.
