Sinechostictus (Sinechostictus) multisulcatus cariniger Korge, 1971 syn. nov.

Notes.

In the revision of the Caucasian species of ruficorne - stomoides group, after downgrading S. lubricus Lutsnik, 1938 and S. cariniger Korge, 1971 to subspecies of S. multisulcatus Reitter, 1890, Fassati (1992) defined the distribution of the subspecies ( S. multisulcatus multisulcatus from high altitudes in Central Caucasus; S. cariniger from NE Turkey and Georgia; S. lubricus from the Western Caucasus, Lesser Caucasus, and Georgia). He also described some diagnostic exoskeletal characters, but in the text frequently repeated the words "in general" and “often”, so that we suppose that, in his opinion, overlapping of characters are frequent in the subspecies. Kryzhanovskij et al. (1995) list the three subspecies from the Caucasus, but a note by Belousov (Kryzhanovskij et al. 1995: 90, note no. 188) says: “… since the infraspecific structure of multisulcatum Rtt. remains obscure". Later S. lubricus was considered by all authors as a synonym of S. multisulcatus ( Lorenz 1998, 2005; Marggi et al. 2003), while S. cariniger , formerly listed as synonym of S. multisulcatus in Lorenz (1998), was later considered a valid subspecies ( Marggi et al. 2003; Marggi et al. 2017).

We examined several specimens from NE Turkey, Georgia, Azerbaijan (new record: N Azerbaijan, Kusary, Shakh-Nabad-Tshai, 3400 m), and southern Russia (Abchasia, Sochi, Krasnodarski Kraj and, confirming S. lubricus as a synonym, we think that S. cariniger should also be synonymized with the nominotypical form. Therefore we state the following synonymy, with the junior synonym listed first: Sinechostictus (Sinechostictus) multisulcatus cariniger Korge, 1971 = Sinechostictus (Sinechostictus) multisulcatus (Reitter, 1890) syn. nov. Current distribution: E: AB, GG, ST; A: TR.
