Eppelsheim (1887, 422) described the species from one female specimen taken in the Russian Far East near Vladivostok (“Ein von Herrn Graeser bei Wladiwostok gesammeltes Ψ verdanke ich der Güte des Herrn Koltze”). The holotype in the Eppelsheim collection in the Naturhistorisches Museum, Wien, is labeled as follows: “Ψ” / “ inexspectatus mihi Wladiwostok, Amur leg. Graeser” / ” inexspectatus Epp. Deutsch. Ent. Zeit. 1887 p. 422 ” / ”inexpectatus Epp. Dedt. J. Müller” / “ TYPUS ”. The specimen is in bad condition, six outer segments of left antenna are missing, small lateral portion of right elytron is missing, the abdomen is separated from the rest of the body, with tergites separated (first two showing Dermestes damage) separately and most of the sternites missing. The specimen was arranged on a mounting plate, the somewhat damaged female genital segment was glued to the plate with the beetle.

Medium-sized species, sharing many character states with O . aenescens , but different by the differently shaped aedoeagus, and by several external characters, as given in the description. Description. In all character states similar to O . aenescens , but different as follows: average size smaller, body form more slender; surface of head and pronotum with more coppery lustre; legs slightly paler, mostly piceous with all tarsi more or less paler; head of more rounded shape with entirely rounded posterior angles; punctation of head similar to that of O . aenescens , but on average somewhat denser; pronotum not voluminous, punctation similar to that of O . aenescens , but less dense and somewhat coarser, no more than slightly finer and denser than that of disc of head; impunctate midline wider and therefore more apparent. Male. Area behind anterior angles of pronotum densely punctate. Sternite 7 with medioapical emargination similar to that of O . aenescens , but less deep and more obtuse. Genital segment with sternite 9 wider, with apex finely notched (Fig. 22). Tergite 10 wider than that of O . aenescens , with entirely rounded apex, less densely setose (Fig. 23). Aedoeagus (Figs. 24–27) quite different from that of O . aenescens , with right lateral portion of median lobe in ventral view conspicuously dilated, and with apex of median lobe missing short longitudinal carina on face adjacent to paramere (Fig. 25). Paramere situated on median lobe quite asymmetrically, of different shape (Fig. 26), in general distinctly longer and narrower, with acute apex not reaching apex of median lobe and without fine longitudinal carina on face away from median lobe; underside of paramere lacking sensory peg setae, but with minute sensory setae situated as in Fig. 27. Female. Area behind anterior angles of pronotum sparingly punctate or almost impuncate. Tergite 10 of genital segment similar to that of O . aenescens , but narrower, with narrower apex (Fig. 28). Body length 11.0–14.0 mm. Geographical distribution. Ocypus inexspectatus occurs in the Russian Far East in Primorskyi Kray, from southern Ussuri area northwest to Lake Khanka and northeast to the southern portion of the Sikhote Alin mountain range. Bionomics. Very little is known about the habitat requirements of this species. It occurs from lowland (100–300 m) to middle mountain elevations (650–900 m) in the Sikhote Alin mountain range. Recognition and comments. Ocypus inexspectatus may only be confused with O . aenescens , the only other species that has the second abdominal tergite entirely punctate and pubescent. The two species may be easily distinguished by the differently shaped aedoeagi (Figs. 17, 24) and tergites 10 of the female genital segments (Figs. 21, 28), as well as by several external characters discussed in the description of O . inexspectatus . For the comparison with O . graeseri see the Comments under O . graeseri . Ocypus inexspectatus has not been yet recorded from the territory of the Peoples Republic of China. : Published as part of Smetana, Aleš, 2009, Contributions to the knowledge of the " Staphylinus-complex " (Coleoptera: Staphylinidae: Staphylinini) of China.
