Type material. Allotype (female) in NMNS: TAIWAN, Taichung Hsien [= Taichung City], Anmashan [Daxue Mt. (±ũƜ)] 2230m, 30.IV.–4. V.90, A. Smetana [T32]// ALLOTYPE, Dinothenarus choui A. Smetana 1991 [hand writing, red label]// 057621. The specimen in good condition, mounted on the card, the terminal segment was dissected and mounted on a plastic card by Euparal.

Diagnosis. Dinothenarus choui is the only species of the genus in Taiwan. It can be easily distinguished from other Staphylinina in Taiwan by its reddish-orange head.

Apecholinus fraternus: male. 5–6. Apecholinus imitator: female and female tergite 10. 7. Dinothenarus choui: female, allotype and attached labels. Scale bars: 1–5, 7: 3 mm; 6: 0.5 mm

Bionomics. Types were collected under damaged bags of rotting fertiliser or from a dung baited pitfall trap (Smetana 1992). It seems to be associated with putrefaction.

Distribution. Dinothenarus choui is only known from two counties in central and southern Taiwan (Taichung City and Chiayi County) (Smetana 1992).
