Comments on taxonomy, distribution and bionomics.

The latest summary about Quedius pseudonigriceps  can be found in Solodovnikov (2004) and Assing and Schülke (2012). Quedius pseudonigriceps  is widespread in Southern Europe and Western Asia. We here record it for the first time from Middle Asia: from southern Kazakhstan and northern Kyrgyzstan. It can be easily distinguished from all similar Middle Asian species by the shortened elytra and absence of fine whitish apical seam of palisade fringe on tergite VII.

In Middle Asia Q. pseudonigriceps  is brachypterous (Fig. 3F) and characterized by the significant variability in the structure of aedeagus which nevertheless has no geographical pattern and leaves no doubt about species identity (Fig. 11). Solodovnikov (2004) noted that Quedius kirklarensis  from Turkey is almost identical with Q. pseudonigriceps  from South Europe and Western Asia except for the absence of palisade fringe on abdominal tergite VII in the former. Therefore he suggested that Q. kirklarensis  may be a brachypterous form of Q. pseudonigriceps  . A new synonymy could not be established back then because of the limited material and also due to the similar species Quedius cohaesus  and Quedius turkmenicus  from Middle Asia. With more material available here for all relevant taxa we can undoubtedly place Quedius kirklarensis  Korge, 1971 in synonymy to Q. pseudonigriceps  Reitter, 1909. For details on Quedius cohaesus  and Quedius turkmenicus  , see below.

In Middle Asia Q. pseudonigriceps  usually inhabits moist leaf litter in deciduous and mixed forests and wet ground debris near streams in the mountains at the altitudes up to 2800 m.
