R e d e s c r i p t i o n: Body length 8.0-11.0 mm; length of forebody 3.8-4.8 mm. Coloration: head black; pronotum blackish, sometimes with the margins narrowly paler (particularly in material from North Turkey); elytra reddish, often with the scutellar and sutural portions more or less distinctly and more or less extensively infuscate; abdomen blackish with the posterior portions of segments VII and VIII and all of segments IX-X reddish; legs pale-reddish; antennae with the basal antennomeres reddish and the apical antennomeres brown to dark-brown. Externally highly similar to Q. nivicola , distinguished only by the shape of the aedeagus.

♂: aedeagus 1.05-1.13 mm long; median lobe and paramere shaped as in Figs 40-49.

C o m p a r a t i v e n o t e s: Quedius ortrudae is distinguished from other representatives of the Q. nivicola group as follows:

from Q. nivicola by an apically less flat (lateral view) and less acute (ventral view) median lobe of the aedeagus and by a slightly less broad paramere with on average fewer peg-setae;

from Q. problematicus by darker coloration (particularly of the elytra and the pronotum, the latter rarely with paler margins) and by the shape of the aedeagus ( Q. problematicus : apical portion of median lobe slightly sinuate, slightly longer; subapical tooth more distant from apex of median lobe);

from Q. josue by darker coloration of the pronotum ( Q. josue : pronotum mostly darkbrown to blackish-brown with narrowly yellowish margins; elytra yellowish with the sutural halves usually distinctly and extensively infuscate) and by a larger aedeagus with the apex of the median lobe slightly longer and slightly more acute in ventral view.

D i s t r i b u t i o n a n d n a t u r a l h i s t o r y: The currently known distribution ranges from the Aegean islands Ikaría, Samos, and Kos across Turkey eastwards to North Iraq. The specimens were collected in various habitats (forests, open land). The altitudes range from near sea-level to above 2300 m. Teneral adults were found in July (North Anatolia). Available evidence suggests that, as in Q. nivicola , the habitat of Q. ortrudae is essentially subterranean. Records of the species are rare and mostly based on singletons. Some were collected with pitfall traps, and three specimens were found in caves. The absolute number of records and specimens may convey a different impression, but it should be kept in mind that they represent the result of numerous field trips by various collectors amounting, in total, to years of intense collecting activity in Turkey alone. Moreover, the majority of records are from regions characterized by limestone (especially central southern Anatolia), and the general distribution of records is similar to that observed also for species of the Q. coloratus group, which too appear to have a hypogean reproduction habitat ( ASSING 2017a, e).
