Mesosternal interspace ( Fig. 51 ) very wide, 3 times wider than its height and 1.5 times wider than mesosternal lobes. Tympanum practically absent, but in some females a vestigial one much smaller than the neighbour stigmal area. Abdominal tergites as in male. Hind femur ( Figs. 43–45 ) 2.6–2.7 times longer than its height. Hind tibia with 9–10 inner and outer spines. Subgenital plate almost as long as wide, in some females slightly longer.

Colouration of female. Body greyish brown, in some females lighter greyish, with black, brown, and milky brown spots, stains and parts. Head mostly milky brown with black spots on vertex and frontal ridge. Eyes greyish light brown, the area around lateral ocelli blackened. Basal segments of antenna milky brown regularly darkening towards apex to blackish brown. Pronotum and abdomen greyish brown to brown with black spots and light milky brown stains on lateral surface of abdomen; typical light bands on paranota distinct on anterior and posterior margins. Fore and mid legs milky brown, darker in some females with irregular black spots. Hind legs as in male.

Remarks. Nocaracris tauricola and its synonym N. rigidus were described by Ramme (1951) and Mistschenko (1951), respectively. The type specimens, all of which are females, were collected much earlier, in 1895 and 1904 by M. Holtz and W. Siehe from the same place Cilician Taurus (Bolkar Dağları) ( Ünal 2016). It has not been found again for 119 years. Ongoing extensive field trips this species was found after a century and the male sex for the first time. The type locality is a typical mountain steppe on stony and rocky ground in the alpine region of Bolkar Mountains. Because of the habitat destruction around the type locality by the heavy grazing it is found only from the restricted area near a summit. Therefore, it was not easy to find it. This may be the reason why this species could not be found in the previous trips to these Mountains. But it is the fact that finding the correct point ( Fig. 36 ), not only in the huge mountain ridge but also in the type locality (Dümbelek), was the most important reason for the rediscovery of this species.

The N. bodenheimeri sp. group is divided into two subgroups, N. burri subgroup (see the diagnosis of the new species, N. nebulosa , above) and N. bodenheimeri subgroup by the item 14 of the key in Ünal (2016: 133). This species is a member of the N. bodenheimeri subgroup, which is composed of N. bodenheimeri ( Uvarov, 1940) , N. idrisi (Karabağ, 1953) , N. cejchani Ünal, 2016 , N. cinerascens Ramme, 1951 and N. tauricola Ramme, 1951 .

This species was separated from all other species of the group by the large and protruding head of the female ( Ünal 2016). This relationship was also confirmed on the basis of the male sex. It can be compared with two related and geographically near species, N. bodemheimeri ( Uvarov, 1940) and N. cejchani Ünal, 2016 . It is different from these two species by the stouter body and legs (clearly more slender, and especially legs and hind tibia thinner in N. bodenheimeri and N. cejchani ), the sloping fastigium of vertex (flat and straight in N. bodenheimeri , but more sloping in N. cejchani ), the grooved frontal ridge indistinctly narrowing just below median ocellus (in N. bodemheimeri deeply grooved, but distinctly narrowed below the median ocellus; in N. cejchani shallow groove and slightly narrowed below the ocellus), the slightly compressed pronotum laterally with less raised median carina and the less depressed area between the median and lateral carinae, so it is seen a little bit swollen (distinctly more compressed pronotum and more raised median carina, and the area between the median and lateral carinae clearly more depressed in N. bodenheimeri and N. cejchani ), the prosternum similar to N. bodenheimeri , but collar shaped in N. cejchani , the hind femur widened in basal part and sharply narrowing towards genicular lobes (regularly narrowing in N. bodenheimeri and N. cejchani ), the wide abdomen, slightly depressed dorsoventrally with less distinct carinae (abdomen distinctly more compressed laterally, median and lateral carinae of abdomen raised, clearly more distinct in N. bodenheimeri and N. cejchani ), the tympanum (absent in N. bodenheimeri and strongly reduced, a vestigial one much smaller than the neighbour stigmal area in N. cejchani ), the narrow and not raised arch of zygoma (narrow and raised in N. bodenheimeri , wider and not raised in N. cejchani ), the wide apodemes with very distinct apical notch (apodemes narrower and with weak apical notch in N. bodenheimeri ; apodemes narrow and distinct apical notch in N. cejchani ) and, the larger male size.
