7A1287AAFFA9FFEFD1A5F9BAFA937D27.taxon	diagnosis	Diagnosis. This species is similar to D. punctipennis in body size and coloration, but D. punctipennis has more elongate antennomeres. Regarding the body size and short antennomeres, this species is also similar to D. bilobatus sp. nov. and D. bisegmentatus. This species can be separated from them by less dilated first four segments of protarsi, thicker parameres of aedeagus and the shape of male sternite VIII.	en	Huang, Tian, Janák, Jiří, Zhou, Hong-Zhang (2025): Revision of the genus Diochus Erichson (Coleoptera: Staphylinidae, Staphylininae, Diochini) from Thailand and Myanmar.

7A1287AAFFA3FFEBD1A5FE60FDE17BD7.taxon	diagnosis	Diagnosis. Regarding the similar shape of male sternite VIII, similar structure of the male aedeagus and the female spermatheca, the new species is related to D. antennatus and D. bisegmentatus, but can be distinguished by less elongate pronotum and relatively shorter parameres of the male aedeagus. This species possesses an elevation between eyes, which also distinguishes it from D. antennatus.	en	Huang, Tian, Janák, Jiří, Zhou, Hong-Zhang (2025): Revision of the genus Diochus Erichson (Coleoptera: Staphylinidae, Staphylininae, Diochini) from Thailand and Myanmar.

7A1287AAFFBAFFF3D1A5FB6CFC987917.taxon	diagnosis	Diagnosis. This new species is small in size and with short antennae, similar to D. antennatus. The main difference is the shape of sternite VIII: the new species has a less elongated sternite VIII in male. Moreover, this new species has a rounded head and distinctly shorter antennomeres (antennomeres 6 – 10 transverse), which can be also used to distinguish it from other species.	en	Huang, Tian, Janák, Jiří, Zhou, Hong-Zhang (2025): Revision of the genus Diochus Erichson (Coleoptera: Staphylinidae, Staphylininae, Diochini) from Thailand and Myanmar.

This species resembles D. bilobatus sp. nov. and D. antennatus in the size, antennae, the shape of male sternite VIII and the female spermatheca. This species can be distinguished from D. bilobatus sp. nov. by longer parameres and different inner structure of the male aedeagus. In comparison with D. antennatus, this species possesses a round elevation between eyes in males, while D. antennatus is lacking such elevation. Besides this, the inner structure of aedeagus is also different from D. antennatus.	en	Huang, Tian, Janák, Jiří, Zhou, Hong-Zhang (2025): Revision of the genus Diochus Erichson (Coleoptera: Staphylinidae, Staphylininae, Diochini) from Thailand and Myanmar.
