Diagnosis. This new species is a member of the N. bodenheimeri sp. group by the usual form of hind femur, the distinct lateral carinae and the raised median carina of pronotum, the body shape not strongly compressed laterally. It is included in the N. burri subgroup (see Remarks section of N. tauricola below) which is composed of N. burri ( Uvarov, 1949) , N. sureyana Ramme, 1951 , N. emirdagi Ünal, 2016 and N. tardus Ünal, Bugrov & Jetybayev, 2016 by the stout and large body size.

This new species is near to N. burri in the body shape with the most depressed dorso ventrally in the species subgroup, the narrow and more sloping fastigium of vertex and the shape of hind femur, but the structure of prosternum (sharper and pointed in N. burri ), the less distinct and lower median carinae of pronotum, the wide mesosternal interspace (clearly narrower in N. burri ), the colouration of hind tibia (in N. burri unicolour bright red including ventral, dorsal surfaces and the inner spines; the longitudinal black stripe absent), the weaker typical light bands on paranota and abdomen (they are the most sharply distinct in N. burri in the species subgroup), the structure of the male phallus with the raised and wide arch of zygoma, the narrower posterior lobes of zygoma and wider apodemes (distinctly narrow and not raised arch of zygoma; wider posterior lobes of zygoma and narrower apodemes in N. burri ) are different.

It differs from N. sureyana by the slender and more depressed body and pronotum dorso ventrally (body stout, compressed laterally and pronotum high in lateral view in N. sureyana ), the narrower and less depressed fastigium of vertex, the prosternum with tongue shaped median projection (raised almost triangular, collar shaped in N. sureyana ), the red hind tibia mostly with a longitudinal black stripe on inner surface in both sexes (male hind tibia black, female hind tibia yellow or slightly orange without any longitudinal black stripe in N. sureyana ), the shape of slender hind femur with regularly narrowing lateral view towards genicular lobes (hind femur stout, strongly widened basal part and sharply narrowed in preapical part in N. sureyana ), the wider arch of zygoma (clearly narrower and not raised in N. sureyana ), the narrower posterior lobes of zygoma.

The new species differs from N. emirdagi and N. tardus by the slender, smaller and clearly more depressed body and pronotum shape, the more distinct lateral carinae of pronotum, the narrower and more sloping fastigium of vertex, the prosternum with the tongue shaped median projection (collar shaped in N. emirdagi , irregularly sinuous, not pointed in N. tardus ), the shape of slender and narrow hind femur (distinctly stouter, much wider basal part of hind femur in both related species), the colouration of hind tibia (hind tibia black in male and dark blue in female of N. tardus ; orange red or dirty orange red, but without longitudinal black stripe in N. emirdagi ), the red tarsus (also red in N. tardus ; but cream in N. emirdagi ). The phallus is different from N. emirdagi with the wider and raised arch of zygoma (narrower and not raised in N. emirdagi ), the narrower posterior lobes of zygoma, the wider posterior valves of penis and wider apodemes. The distinct typical light bands on paranota (absent in N. emirdagi ) are also different. The phallus is different from N. tardus with the raised and more elongated arch of zygoma (not raised in N. tardus ).

The hind tibia colouration is similar to N. idrisi from N. Turkey with the orange-red ground and a longitudinal black stripe (at least in some specimens of N. idrisi ). But the larger and more depressed body (smaller and clearly more compressed laterally in N. idrisi ), the depressed fastigium of vertex, the wider and raised arch of zygoma, the narrow and long posterior lobes of zygoma (arch of zygoma narrower and not raised, posterior lobes of zygoma short and wide in N. idrisi ), the wide apodemes with distinct apical notch (apodemes narrow and at most with a weak apical notch in N. idrisi ) are different.

Etymology. The Latin word “ nebulosa ” means misty, which refers to the habitat of this new species ( Fig. 16 ). The location where I found the Nocaracris nebulosa sp. nov. is placed on the edge of a very high vertical cliff (almost 1000 m. high) was misty in all my visits. The mist comes from the lowlands of steep slopes (from the Mediterranean Sea) and reaching to above 2000 m. in a short distance. The mist, rising to the sky, is rapidly forming clouds at this point, like a cloud factory. So, this very impressive place was misty at any time, and it is reflected in naming the new species.

Remarks. The habitat of this species ( Fig. 16 ) is a high mountain steppe ( Astragalus sp. , Achantolimon sp., Thymus sp. etc.) on rocky-stony ground situated on the southern edge of the Taşeli Plateau. This location has been visited four times in three trips. On the first visit on 22 September 2017, 1 male subadult and 2 female nymphs were found. It was presumed that these specimens probably belong to an unknown species of Nocaracris . Therefore, to find matured forms the same place was visited on 29 and 30 June 2018 and some adults were found in two nearby locations. One more time it was found an opportunity to visit the same place on 29 June 2019. But this time, despite the same date with the previous visit it could not be found any Nocaracris . Because of the delayed warming of the climate in 2019 the habitat was mostly covered by the large snow islands, and it was quite cold.
