Key to the species of the Quedius pluvialis group

1 Abdominal tergite 2 (in front of first fully visible tergite) glabrous; abdominal tergite 8 (fifth visible) with apical seam of palisade setae. Aedoeagus as in Figs 8-10 . Length 10.5 mm ................................................................................................. Q. egregius nov.sp.

- Abdominal tergite 2 (in front of first fully visible tergite) entirely punctate and pubescent, or at least with punctures on apical part; abdominal tergite 8 (fifth visible) lacking apical seam of palisade setae..................................................................................2

2 Apical portion of median lobe of aedoeagus dagger-like, without elongate lamina ventrally (lateral view, Fig. 13 in SMETANA 2010: 253). Additional puncture between posterior frontal puncture and puncture at posterior margin of head present (rarely missing unilaterally). Length 8.0- 8.8 mm ................................ Q. pluvialis SMETANA, 1998

- Apical portion of median lobe of aedoeagus lancet- or dagger-like, but if dagger-like then with elongate lamina ventrally (lateral view, Fig. 7 in SMETANA 2010: 251; Fig. 11 in SMETANA, 2012:311). Additional puncture between posterior frontal puncture and puncture at posterior margin of head absent (rarely present unilaterally)....................3

3 Apical portion of median lobe of aedoeagus dagger-like ( Fig. 8 ).......................................4

- Apical portion of median lobe of aedoeagus lancet-like ( Fig. 3 ; Fig. 3 in SMETANA 2010 a: 251).........................................................................................................................5

4 Male secondary sexual characters present on abdominal sternite 6. Ventral lamina of median lobe relatively short ( Fig. 7 in SMETANA 2010 a: 151). Length 9.0- 10.2 mm ............ .......................................................................................................... Q. oui SMETANA, 2010

- Male secondary sexual characters absent from abdominal sternite 6. Ventral lamina of median lobe very long (Fig. 11 in SMETANA 2012d: 311). Length 9.5-10.5 mm .................. .............................................................................................. Q. schneideri SMETANA, 2012

5 Aedoeagus large and robust, paramere widely fusiform ( Fig. 3 ). Length 10.0- 10.5 mm ...... .................................................................................................................... Q. nemo nov.sp.

- Aedoeagus markedly smaller and less robust, paramere narrow, more or less parallelsided ( Fig. 3 in SMETANA 2010 a: 251). Length 8.5-9.2 mm ...................................... ................................................................................................ Q. shunichii SMETANA, 2010
