D i a g n o s i s. A species in all characers similar to Q. ryvkini nov.sp., but different by darker body coloration and by the differently shaped aedoeagus.

D e s c r i p t i o n. Head black, pronotum uniformly piceous, elytra piceous, abdomen piceous-black to black with apical margins of tergites more or less narrowly paler. Mandibles rufotestaceous, palpi, antennae and legs uniformly pale testaceous but first three antennal segments vaguely, indefinitely darkened.

Male. First four segments of front tarsus similar to those of Q. ryvkini , but less dilated, but segment two as wide as apex of tibia, as in Q. ryvkini . Sternite 8 with four strong setae on right side and three on left side; with medioapical emargination similar, but more acute and less deep ( Fig. 17 ). Both tergite 10 and sternite 9 of genital segment not appreciably different from those of Q. ryvkini ( Figs 18, 19 ). Aedoeagus ( Figs 20, 21 with median lobe similar in shape to that of Q. ryvkini but narrower; paramere similar in shape, but markedly narrower, with subacute apex not reaching apex of median lobe; four apical setae, median pair markedly longer than lateral pair and two long setae at each lateral margin close to apex; sensory peg setae on underside less numerous, forming a narrow field on apical portion.

Female unknown.

Length 7.5 mm.

E t y m o l o g y. The specific epithet is the Latin masculine noun aedilis, - is, m (an aedile, official in ancient Rome).

G e o g r a p h i c a l d i s t r i b u t i o n. Quedius aedilis is at present known only from the type locality in Sikhote-Alin range in the Maritime Province of the Russian Far East.

B i o n o m i c s.The holotype was taken from a yellow pan trap, but it is not known in what habitat the traps were set. It is apparent that Q. ryvkini and Q. aedilis share the same habitat.
