With thanks to Prof. Dr. Mustafa Ünal for the possible identification (not certain without the specimen)
Körahmet, ARTVİN ● Turkey
Taxonomy: Phonochorion Uvarov (Orthoptera: Tettigoniidae: Phaneropterinae) is a little known genus consisting of three species: Ph. satunini, Ph. artvinensis and Ph. uvarovi. The genus Phonochorion was established by Uvarov in 1916 for a single species, Phonochorion satunini. Bey-Bienko in 1954 described the second, Ph. artvinensis. T. Karabag found the third Ph. uvarovi amongst the collection of Orthoptera made by Dr. P. Davis in Turkey in 1952.
Description: Body size of Ph. artvinensis is relatively large; when the fastigium is viewed from above, the dorsal cavity is concave at the sides, shallow and mainly located at the base.
In males when the first tergum is viewed from above the metanotal gland distinctly folds and rises upwards forming a curved bracket or brace shape. In males the subgenital plate is red-lilac, narrows gradually at the middle, the neck is long (3.00–4.30 mm) and narrows down towards apex except in individuals from populations east of the Coruh Canyon, in which the neck is relatively short (2.10–3.00 mm). In males the cerci are relatively thick (0.80–1.10 mm) and long (3.50–4.45 mm).
Body coloring of males is mainly black and lilac.
In females viewed from above the tegmina clearly protrudes from under the pronotum. And the subgenital plate has a blunt protrusion at the anterior end. Ovipositor length can range between 9.00–15.30 mm.
Habitat: The 3 species of Phonochorion are associated whith various herbaceous plants and shrubs (mostly Urtica dioca, Sambucus nigra and Rumex tuberosum) and pasture vegetation forming discrete local populations in areas with a rainy, humid and cold climate, at altitude between 1000–2600 m.
Distribution: The genus Phonochorion is distributed from the Yağmurdere in the Gümüşhane province of Turkey to the Djvari Mindori plateau in the Khulo province of Georgia, on the northern slopes of the East Black Sea and Lesser Caucasus Mountains. Only Ph. satunini is distributed in Georgia.
