Lee, Seung-Gyu & Ahn, Kee-Jeong, 2022, Korean species of the Atheta Thomson subgenus Dimetrota Mulsant & Rey (Coleoptera: Staphylinidae: Aleocharinae) with a description of new species, Zootaxa 5138 (4), pp. 401-416 : 411

Atheta (Dimetrota) weisei Bernhauer, 1907

( Fig. 8H )

Remarks. Atheta (Dimetrota) weisei was recorded by Paśnik (2001) for the first time in North Korea and by Cho et al. (2002) for the first time in South Korea. But, a habitus photograph of A. (D.) weisei provided by the paper of Cho et al. is incorrect identification of Gyrophaena species.

While studying Korean Athetini , we found that this species is similar to Atheta (Tetropla) nigritula Gravenhorst (1802) . After studying the syntype of A. (D.) weisei and the lectotype of A. (T.) nigritula , we suspect that the character difference between these two species is insufficient to separate as different species. However, a more thorough comparative study including minute characters of specimens from broader distributional areas should be conducted to propose a synonym, A. (D.) weisei under A. (T.) nigritula . Almost Korean specimens were found on mushrooms and some were collected from FIT or bait trap.
