( Fig. 7 )

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).
