Description. Refer to the description in Smetana 1995: 68–69, and figures 102–107.

Geographical distribution. Quedius pseudonymos is endemic to Taiwan. It is at present known from the following Hsiens: Chiai, Hualien, Ilan, Kaohsiung and Taichung.

Bionomics. Quedius pseudonymos occurs in forest habitats at middle mountainous elevations, from about 2100 m to 2500 m. Specimens were collected in mixed coniferous ( Chamaecyparis ) and broadleaved forests in wet moss, and by sifting various forest floor debris, particularly under dense growths of ferns ( Smetana 1995: 70).

Recognition and comments. Quedius pseudonymos is in all characters quite similar to Q. maculiventris and differs mainly by the different shape of the aedoeagus, particularly by the shape of the median lobe which is dilated anteriorly before narrowed into apical portion (Fig. 104 in Smetana, 1995). Male sternite 8 has five long setae on each side, compared to three or four in Q. maculiventris ( Figs. 17 , and 101 in Smetana 1995). Externally, the average size of Q. pseudonymos is slightly smaller than that of Q. maculiventris , and the lateral patches of pale hairs on the abdominal tergites are less distinct.

Etymology. The specific epithet is the Greek word ψευδωνυμος (falsely called, under false name) in apposition. It refers to the original misinterpretation of the species.
