D e s c r i p t i o n: Body length 5.5-6.0 mm. Habitus as in Fig. 26 . Coloration: Body blackish-brown to blackish, with the pronotum reddish to reddish-brown; legs pale brown; antennae brown to dark-brown. External characters as in O. collare ( Figs 26-27 ).

3: male secondary sexual characters similar to those of O. collare ; posterior margin of sternite VII in the middle distinctly concave; tergite and sternite VIII as in Figs 28-29 ; aedeagus of similar shape as in O. collare , but apical internal structures of different shape and basal internal structure distinctly shorter and stouter (Figs 13, 24, 30).

♀: unknown.

E t y m o l o g y: The name (Latin, adjective: changed, confused) refers to the fact that this species was previously confounded with O. egregium .

Figs 14-25: Ochthephilum collare (REITTER) (14-19), O. egregium (REITTER) (20-21), O. hamatum ASSING (22), O. besucheti (BORDONI) (23), O. permutatum nov.sp. (24), and O. brevispinosum nov.sp. (25): internal structures of aedeagus; long curved apical structure (left), elongate apical structure and dorso-apical lamellate structure (middle), and long basal structure (right) (14: Dalmatia; 15: Greece, Thessalia; 16: Greece, Fthiotis; 17: Greece, Pelopónnisos; 18: Austria; 19: Germany; 20: paralectotype; 21: Azerbaijan, "Helenendorf"; 22: paratype; 23: Turkey, Ordu; 24: paratype; 25: holotype). Scale bar: 0.2 mm.

C o m p a r a t i v e n o t e s: The new species is reliably distinguished from the similar O. collare and O. egregium only based on the internal structures of the aedeagus, from both by the distinctly shorter and stouter basal structure and by the differently shaped apical structures, from the latter additionally by the larger aedeagus and the much larger dorso-apical lamellate structure.

D i s t r i b u t i o n a n d b i o n o m i c s: The known distribution of this species is confined to Azerbaijan and northwestern Iran ( Map 2 ). These records suggest that O. permutatum may be a Caspian element, but more data are needed to verify this conclusion. The two paratypes from Iran were collected in June.
