Comments on taxonomy and lectotype designation.

In the original description of Q. novus  , Eppelsheim (1892) stated that he had examined numerous specimens from Tashkent and one from Margelan [Margilan in Uzbekistan]. He also stated in the introduction of that study that he received material from ‘Turkestan’ from multiple collections of Hauser, Staudinger and Reitter. In particular, he mentioned that the material from Tashkent from Reitter’s collection was collected by Leder. In NMW altogether we found 11 conspecific specimens, all originally from Eppelsheim’s collection (with printed label "c.Epplsh. Steind."), whose morphology and label data match with the original description. We consider all of them to be syntypes. Of them, 8 specimens (on 5 pins) were earlier supplied with the curatorial printed red labels “types”; only two specimens have what we consider Eppelsheim’s hand written labels " novus  Epp. Taschkent Leder." and one specimen having " novus  Epp. Deutsch. ent. Zeit. 1892. P. 331" label in a different handwriting probably attached by somebody later, after the species description was published. Also in the ZIN collection we found two more specimens conspecific with the syntypes at NMW and with the label "Taschkent Leder. Reitter" indicating that they are likely to be syntypes as well. Examination of all syntypes confirms that previous authors correctly interpreted this species. In order to fix its identity, here we designate one male syntype from NMW as the lectotype. Due to the intraspecific variability (Figs 16, 17) and resulting new synonymy Q. novus  = Q. dzhambulensis  (see below), we chose a syntype for lectotypification which has a more narrow longitudinal row of sensory peg setae on the paramere, best matching Coiffait’s (1967) illustration for Q. novus  .

Comments on the new synonym.

The aedeagus of Q. novus  was first illustrated by Wüsthoff (1938) based on non-type material. Coiffait (1963, 1970, 1978) redescribed the species, also illustrated the aedeagus and provided more records for Q. novus  from Uzbekistan. Our examination of syntypes proved both Wüsthoff’s and Coiffait’s interpretation of this species was correct. Also Coiffait (1967) described Q. dzambulensis  from Dzambul (Kazakhstan) (Fig. 16), a species which seemed to be very similar to Q. novus  even from the illustrations of the aedeagi for both species.

Later, Boháč (1988) examined material from the ZIN collection and provided new records from Uzbekistan, Tajikistan, Kyrgyzstan of Q. dzambulensis  and only one record from Uzbekistan for Q. novus  . He also stated that Q. novus  is very closely related to Q. dzambulensis  with which it can be easily confused. We checked all material from ZIN studied by Boháč (1988) and found that, without knowing it, the only specimens he identified as Q. novus  were the syntypes of that species. All other specimens he identified as Q. dzambulensis  .

Our examination of a broader sample from Middle Asia, including types of both species, showed continuous variability in the structure of the aedeagus connecting the state of Q. novus  with the state of Q. dzambulensis  . Sensory peg setae on the paramere vary in arrangement, from denser (as in Coiffait’s illustration for Q. novus  ) to sparser (as in Coiffait’s illustration for Q. dzambulenisis  ) witin a longitudinal group (Fig. 17). The mentioned variability has no geographic pattern. Therefore, we consider Q. dzambulensis  Coiffait, 1967 to be a junior synonym of Q. novus  Epp.

Diagnosis.

Body dark brown; elytra with lighter colored humeri and shallow micropunctation between punctures; antennae slightly paler; scutellum without setiferous punctation. (Figs 3E, 16A) Aedeagus (Figs 16B, C; 17): ventral tooth of median lobe located remotely from its apex; median lobe and paramere very broad (Figs 16B, 17); apex of paramere obtusely pointed and sensory peg setae arranged in long wide band in the middle of paramere (Figs 16C, 17). Quedius novus  can be easily distinguished from the similar Middle Asian species Quedius umbrinus  by the coloration and micropunctation of elytra and also by the mentioned above aedeagal characters.

Distribution.

Based on the literature data (Table 1) that proved to be reliable for this species and the material examined here, Q. novus  is widely distributed in Middle Asia and appears the most common in southern Kazakhstan, eastern Uzbekistan, western Kyrgyzstan and northeastern Tajikistan (Fig. 17).

Bionomics.

Quedius novus  prefers various wet ground based plant debris or moss usually near water bodies. It seems to occur both in forested and open habitats, up to 2700 m. Occasionally it was also found under stones and in dung.
