Comments on taxonomy, distributon and bionomics.

The latest summary of diagnostic characters, bionomics and distribution of Q. limbatus , a common Western Palearctic species can be found in Assing and Schülke (2012). Based on earlier records (Table 1) and newly examined material in Middle Asia it is known from southern Kazakhstan and Turkmenistan.

Among all Middle Asian species Q. limbatus is more similar to Q. cohaesus from which it can be easily distinguished by the structure of aedeagus with a sharper apex of the median lobe (in lateral view) and sensory peg setae of the paramere (underside) arranged in short regular rows, slightly diverging from each other basally.

Usually this species occurs in lowlands up to the subalpine zone, but is mostly confined to forests and humid ground-based debris, often near streams ( Assing and Schülke 2012). In Middle Asia Q. limbatus was collected at elevations up to 1750 m near rivers in forested landscapes.
