Name
Buthus kunti Yağmur & Koç & Lourenço, 2011 sp. n. – Wikispecies link – ZooBank link – Pensoft Profile
Type material:
Cyprus, 1 female holotype, Karpaz Region, Dipkarpaz Town (İskele), 2 km south east, 35°35'05"N, 34°25'23"E, leg. H. Koç (MTAS). Paratypes: 1 subadult male, Karpaz Region, Zafer headland, 2 km west, 35°41'29"N, 34°33'43"E, leg. M. Z. Yıldız and B. Göçmen (MTAS). 1 subadult male, Güzelyurt District (Morphou), about 5 km south east of Güzelyurt town, leg. H. Koç (MNHN) (Fig. 13).
Note:
Although Simon’s female specimen may belong to the new species, we decided not to include it among the type material because (i) it is poorly preserved (ii) the precise collecting site is unknown.
Derivatio nominis:
The species is dedicated to Kadir Boğaç Kunt who is the founder of the Turkish Arachnological Society.
Diagnosis:
Scorpion of medium to large size, reaching a total length of 73 mm. General coloration yellow to pale yellow, with brownish spots on the carinae of carapace; legs with diffused brownish spots. Carinae moderately to strongly marked; granulations moderately to weakly marked. Fixed and movable fingers with 12 rows of granules. Pectines with 27 to 29 teeth in males, 24–25 in female.
Relationships:
Buthus kunti sp. n., belongs to the “Buthus occitanus” species complex. It can be distinguished from the other species of Buthus and in particular from Buthus israelis Shulov & Amitai, 1959, a species distributed in the nearby region of the Middle East, by the following characters: (i) Buthus israelis is smaller, measuring up to 62 mm in total length for females; (ii) according to Levy and Amitai (1980)[1] pectinal teeth 28–33 in males, 22–28 in females, the new species has a slightly reduced number of pectinal teeth; (iii) metasomal segment II is longer than wide in the female of the new species, whereas it is wider than long in the female of Buthus israelis; (iv) pedipalp segments are oligotrichous (sense Vachon 1952[2]) in the new species, whereas they are polytrichous in Buthus israelis.
Taxonomic note:
As already exposed in a recent paper (Lourenço et al. 2010[3]), the Israeli and Sinai populations were originally described only as a variety: Buthus occitanus mardochei var. israelis Shulov & Amitai, 1959. Subsequently, this form was raised to subspecies level as Buthus occitanus israelis (Levy and Amitai 1980[1]). This decision followed the previous taxonomic position adopted by Vachon (1952)[2], who considered almost all Buthus populations from North Africa and Middle East as subspecies of Buthus occitanus. However, a revision of the genus Buthus (Lourenço 2003[4]) revealed that the species Buthus occitanus is limited to France and Spain. Most of the populations of Buthus, previously defined as subspecies and even varieties, were raised to the species level, or described as new species. In the case of Buthus occitanus israelis, it seemed that this population could no longer be considered as a subspecies of Buthus occitanus, both for morphological and especially geographical reasons. Consequently, it was raised to species level, as Buthus israelis (Lourenço et al. 2010[3]). Kovařík (2006)[5] examined material from Egypt and Israel and synonimized Buthus occitanus mardochei var. israelis Shulov & Amitai, 1959 and Buthus occitanus israelis with Buthus intumescens. But Lourenço et al. (2010)[3] didn’t follow this synonimization and accept Buthus occitanus israelis as valid and elevated to species range.

Morphology:
Carapace moderately to strongly granular; anterior margin almost straight and without a median concavity. Carinae strong; anterior median, central median and posterior median carinae strongly granular, with ‘lyre’ configuration. All furrows moderate to strong. Median ocular tubercle at the centre of carapace. Eyes separated by almost three ocular diameters (one median eye absent on the holotype). Three pairs of lateral eyes of moderate size (Fig. 1). Sternum triangular, wider than long. Mesosoma: tergites moderately granular. Three longitudinal carinae moderately crenulate in all tergites; lateral carinae reduced in tergites I and II. Tergite VII pentacarinate. Venter: genital operculum divided longitudinally, which plate with a semi-triangular shape. Pectines: pectinal tooth count: 25–24 in female holotype (28–27, 29–29 in male paratypes); middle basal lamella of the pectines not dilated. Sternites without granules, smooth with elongated spiracles; four carinae on sternite VII; other sternites acarinated and with two vestigial furrows. Metasomal segments I to III with ten crenulated carinae, ventral strongly marked on II-III with lobate granules; segment IV with eight carinae, crenulated; the first four segments with a smooth dorsal depression; segment V with five carinae; the latero-ventral carinae crenulate with 2–3 lobate denticles posteriorly (Fig. 5); ventral median carina not divided posteriorly; anal arc composed of 5–6 ventral teeth, and two lateral lobes. Intercarinal spaces weakly granular. Telson almost smooth; aculeus curved and only slightly shorter than the vesicle, without a subaculear tubercle (Fig. 5).

Ecological notes and biogeography:
Cyprus Island exhibits the Mediterranean climate which is warm and rainy in winter and hot and dry in summer. Rainy season is rare and only occurs in winter in plain areas (İlseven et al. 2006[9]). Sandy soil exists at Zafer headland locality, where the vegetation is composed of Pancratium maritimum, Cakile maritima, Limonium albidum and Pistacia lentiscus (Fig. 14). Redzina soil is present at Güzelyurt, where the habitat was steppe vegetation with small bushes. Buthus kunti sp. n. has allopatric distribution with another species endemic to Cyprus, Mesobuthus cyprius Gantenbein & Kropf, 2000. Interestingly, Cyprus Island is the only territory where representatives of Buthus and Mesobuthus genera have been found together.
The geological evolution of the eastern Mediterranean region, has run a series of prominent geological movements, together with the world wide sea levels rising and falling accompanying the continental glaciations leading to join and split of Cyprus and Anatolia (Robertson 1998[10]). It is thus clear that no consensus yet as to the geological history of Cyprus; Schmidt (1960)[11] express Cyprus was part of a united landmass of the mainland and then was broken piece of the mainland, but according to the modern geological history of the eastern Mediterranean region, Cyprus became due to tectonic movements occurring in the area, Gass (1987)[12] supports during Mesozoic time Mt. Troodos is originated a submarine volcano that arise an oceanic island which occured at Cretaceous-Palaeocene. Whereas Kyrenia Mts (which include Pentadactylos Mt.) maybe as a second island or as a part of the southern Taurus Mts range originated in Eocene then later separated from each other to the south (Cavazza and Wezel 2003[13]). According to widely accepted theory is Mediterranean salinity crisis that the Mediterranean sea dried out and these two island or the Trodos island and southern Tauruian-Kyrenian peninsula connected via landbridges about 5.6 Myrs (Hsü et al. 1977[14]; Cavazza and Wezel 2003[13]). When the refilling of the Mediterranean basin, Cyprus terrestrial animals was isolated for around 5.2 – 5.3 Myrs (Robertson 1998[10]; Gantenbein and Keightley 2004[15] ). This isolation played a major role in forming actual scorpion fauna of Cyprus and molecular and morphological phylogenetic analysis has revealed that populations of the island of Cyprus represent a divergent lineage; so these have been assigned to the species rank (i.e., Mesobuthus cyprius Gantenbein and Kropf, 2000). On the other hand, the other discussions about endemism of some snake species occurring in the two island origin of Cyprus (Troodos and Kyrenia island); Hierophis cypriensis, in only southern Cyprus (i.e., Throodos island) while Platyceps najadum (non-endemic)and Natrix tessellata (non-endemic) is distributed only in northern Cyprus (i.e., Kyrenia island) and also on the mainland (Göçmen et al. 2009[16]). Gantenbein and Keightley (2004)[15] stated his analyses shows that Mesobuthus cyprius occurring in Cyprus is autochthonous. Mesobuthus cyprius recorded in both southern and northern Cyprus. While Mesobuthus cyprius recorded at high elevation in Cyprus, Buthus kunti sp. n. collected at low altitude in dry condition. It is not yet clear if the distribution of new species restricted to Kyrenia island (northern Cyprus). However, Mt. Troodos run vertically and Kyrenia Mts. lay horizontally with less high in Cyprus, are not usually a zoogeographic barrier there. When we take in consideration for this situation we expect the distribution of new species is all over Cyprus. Another point of view explains that as a result of the geological process, it is a localized endemic species in Kyrenia island (Pentadactylos Mt.).
Since the second record of scorpion species, a museum material, Simon’s material the precise collecting site is unknown and poorly preserved, no other species have been seen in several recent field works, so the species might be very rare on the island, and should be investigated again for male specimens under suitable seasonal conditions.
Unplanned urban settlement destroys the habitats of these endemic species. Government agencies are required to take precautions to not destroy habitats.
