Distinction of E. aladaglarensis sp. n. from other Turkish Euscorpius species

In Turkey there are sixteen species of the genus Euscorpius (not including E. aladaglarensis sp. n.), all morphologically and/or geographically well distinguishable from E. aladaglarensis sp. n.

E. aladaglarensis sp. n. has the trichobothrial series V = 3, which easily distinguishes it from E. italicus , and the series on the pedipalp patella external surface em = 4, that distinguishes it from the phylogenetically related species, which usually have em = 3. E. aladaglarensis can be easily distinguished from the, phylogenetically distant, other species with the series trichobothrial em = 4, mainly and easily, for the carina V 1; in E. aladaglarensis sp. n. it follows an oblique direction toward the inside of the trichobothrium Et 1, while in the other species with em = 4, this carina follows a direction toward the external of the trichobothrium Et 1.

The species phylogenetically, morphologically and geographically closest to E. aladaglarensis is E. ciliciensis . These two species are mainly distinguishable by a different number of trichobothria on the pedipalp patella external surface series et and em; E. aladaglarensis has et = 6 (in 76% of pedipalps examined) and em = 4 (in 97.3% of pedipalps examined), while E. ciliciensis has et = 5 (in 87.5 of pedipalps examined by Tropea et al., 2015b) and em = 3 (in 100% of pedipalps examined by Tropea et al., 2015b).
