Description. Male (Holotype): Head 1.3 times higher than wide. Eye slightly longer than antennal foramen. Lateral carina of pronotum sharp and distinct except the both end, slightly raised; prozona clearly depressed; metazona raised and swollen with 2 short tubercular folds, median carina weak or indistict in some males; anterior margin of pronotum slightly concave, posterior margin strongly concave with 3 weak incisions at the end of tubercular folds and median carina; metazona strongly widened and swollen, 1.8 times wider than prozona in dorsal view and 1.5 times higher than prozona in lateral view; paranota distinctly swollen and rounded ( Fig. 185– 186View FIGURES 185 – 192). Femora unarmed except the inner and outer genicular lobes with a small spine. All legs especially hind ones strongly compressed laterally. Prosternum with 2 separate, spiniform projections, in some males strongly reduced like a tubercle; meso- and metasternal projections large, collar-shaped. Subgenital plate ( Fig. 47View FIGURES 33 – 48) 1.2 times wider than long with distinct lateral carina, without styli; posterior margin with a shallow incision, straight in some males. Cerci ( Figs. 15, 15View FIGURES 1 – 16 a) short and broad, apex bidentate, inner arm very large, sharply bidentate, directed inwards, near to distal part, in some males in the middle and slightly recurved; basal lobe large and high. Titillator ( Figs. 31, 31View FIGURES 17 – 32 a) slender, apical arms long and slender along its length, divergent in anterior view, pointed with a small and curved tooth, in lateral view slightly curved to towards poster; basal arms short and broad, distinctly curved upwards; in some males apical arms more divergent with very slightly recurved apex.

Female: Head 1.3 times higher than wide. Eye as large as antennal foramen. Lateral carina of pronotum as in male, weak on both ends; prozona with shallow depression; metazona raised, with 4 tubercular folds, outer two shorter and weaker, slightly longer than prozona; anterior margin slightly concave, posterior margin concave with 3 weak incision at the end of the inner tubercular folds and the middle of them; in lateral view, anterior end of prozona and metazona raised; prozona 1.1 times higher than metazona; pronotum 1.75 times longer than high ( Figs. 187–188View FIGURES 185 – 192). Prosternum with two short, narrow triangular projections, in some female much smaller like triangular tubercle or longer like spine. Tegmina fully concealed under pronotum. Subgenital plate ( Figs. 79View FIGURES 65 – 80, 95View FIGURES 81 – 96) 1.25 times wider than long, posterior margin convex in the middle, basal pits small, D-shaped, twice as wide as long. Cerci ( Fig. 63View FIGURES 49 – 64) short and small, subconical, apex truncate, with a small subapical inner tooth; basal lobe small. Ovipositor (Figs. 111, 187–188) 1.4 times shorter than hind femur; ventral valve with 6-8 irregular teeth, above them with a second row of irregular teeth; ventral and dorsal valves divergent at apex; basal projection of ventral valve triangular, apical part strongly narrowed, pointed at apex ( Fig. 127View FIGURES 113 – 128).

Coloration. Body milky brown, light greenish with black patterns. Dorsal surface of head covered by large dense black spots; ventral parts of clypeus and labrum black or brown, remaining parts milky brown. Pronotum milky brown, in some specimens light green; dorsal and lateral surfaces of prozona with small sparse black spots; lateral carina blackened along its length except the both ends; two inner tubercular folds in metazona and median carina with thin black stripe in some specimens. Inner and outer surfaces of femora with large sparse black spots; basal 3/4 part of inner surface of hind femur pale orange. All tibial spines reddish brown. Abdomen mainly blackened with a median and two lateral longitudinal milky brown bands, the remaining parts with milky brown spots or yellowish spots at the posterior margins of tergites. Male last tergite and cerci black. Abdominal sternites light milky or light yellowish brown, with two short longitudinal black stripes on both sides. Male subgenital plate milky brown with blackened hind margin. Female subgenital plate unicolor yellowish brown. Ovipositor milky brown with blackened apical part; inner margins of valves black basally in dorsal view.

Measurements (mm). Holotype (male): length of body 43.9; pronotum 17.6; hind femur 16.9. Paratypes: length of body: male 45–47.1, female 43.7–45; pronotum: male 17.1–19.7, female 13.2–14.3; hind femur: male 16.9–18.9, female 16.6–19.6; ovipositor 12.4–13.5.

Diagnosis. This new species species is easily recognized by the shape of unique male cerci. It is undoubtedly a member of B. dilatatus  sp. group by the inflated metazona of male pronotum, shape of ovipositor, female subgenital plate and coloration. Its titillator is near to two species B. dilatatus  and B. avanos  . Basal parts of apical arms slender and narrow as in B. dilatatus  , but apical parts not strongly curved towards posterior (in B. dilatatus  strongly and regularly curved towards posterior and downwards). In some specimens of the new species apex of one apical arm (not in both) slightly recurved (in B. avanos  apices of apical arms clearly and strongly recurved including the apical tooth). The male cerci, small size and slender body, female subgenital plate with small basal pits easily separate it from B. dilatatus  and B. avanos  . The small size and general appearance similar to B. conophallus  , but the male cerci, titillator, the shape of basal poits of female subgenital plate are very different. Its female cerci and slender apical arms of titillator similar to B. sureyai  , but the shape of titillator with clearly longer apical arms, male cerci, pronotum, female subgenital plate and slender body are very different.

Remarks. The type locality, Top Dağı (Mt. Top=Mt. Kartevin), located between Ağrı and Muş (also Patnos and Malazgirt districts) is at the border of these provinces. Bayram Göçmen (from Turkey) sent me a female of B. dilatatus  sp. group from this Mountain. Top Dağı is some distance from the main distribution area of this species group. I and Ahmet Erden went to this mountain, but we could not find any Bradyporus  during a long search. At the second attempt after a hard 6 hours walk to another part of the summit ( Fig. 205View FIGURES 202 – 207) we finally found this interesting species. It lives in the high mountain steppe vegetation which is under a moderate threat from grazing, in a very restricted part of the summit.

Two colleagues sent me some photographs of Bradyporus  sp. from Eastern Turkey  . Adrienne Garai (from Hungary) collected some specimens in 2012 from Zara and Yakhisar (Sivas Province) also some distance from the type locality of this species. Later Johan van't Bosch (from the Netherlands) took some photographs of a species in 2014 summer from Ağrı province: between Lake Van and Patnos District, very near to the type locality. It seems to me from these images that they probably belong to this new species. 

A historical and very fragile specimen from Armenia ( ZIN), without titillator and right cercus, and damaged left cercus, possibly belongs to this species because of the pronotal structure and general appearance. The population density is high in the type locality. It has been found from several more locations, but is rare. It should have “Vulnerable” status in the IUCN Red List of Threatened Species for now.

Etymology. This new species is dedicated to herpetologist Prof. Dr. Bayram Göçmen who discovered it for the first time at the top of Mt. Top, E. Turkey.
