Remarks

Mayoral et al. (2018) described this species based on six specimens from high altitude in Sierra Nevada , Spain. The Turkish specimens match well the original description, but we noted a few differences. Therefore , we re-studied the type series specimens. Here, we incorporate a few modifications to the original description, in particular the number of ventral setae and the tarsal I– III chaetotaxy. The number of opisthoventral setae (including 3a setae) ranged from 36 in the holotype to 38–48 in the paratypes (only 36 reported in original description). The tarsal setal formula is as follows: Ta I: 2ω, 3ζ, 1ε, 47–53n; Ta II: 1ω, 2ζ, 1ε, 42–43n; Ta III: 37– 41n.

We have collected> 100 specimens from Türkiye and studied and measured 20. The morphometric data collected from the Turkish specimens is very similar to the original description of the species. The Turkish specimens extend the variability/range for most of the characters ( Table 1). We considered the morphometric differences to be intraspecific variations, especially due to the long geographical distance between populations. The ventral setae ranged 46–52, this is similar to the specimens from Spain (36–48). The leg setal formula in the Turkish specimens is the same as the original description, except for Ta I – III .

The complete leg setal formula for the Turkish specimens (N = 20) is as follows:

Leg I: Ta – 2ω, 4ζ, 1ε, 46–53n ( Fig. 1 ); Ti – 2φ, 1κ, 8n; Ge – 1σ, 1κ, 4n; TFe – 5n; BFe – 1n; Tr – 1n, Cx – 2n. Leg II: Ta – 1ω, 1ζ, 1ε, 40–45n ( Fig. 2 ); Ti – 2φ, 8n; Ge – 1σ, 1κ, 4n; TFe – 4n; BFe – 2n; Tr – 1n, Cx – 1n. Leg III: Ta – 35–43n ( Fig. 3 ); Ti – 1φ, 7n; Ge – 1σ, 4n; TFe – 4n; BFe – 2n; Tr – 1n, Cx – 1n.

In the type and Turkish specimens, there are two setae on distal end of each tarsus in which the length of barbs on distal half increases toward the apical end, so the last barbs are long, and the seta appears as it is bifurcate ( Figs. 1–3 ). Coxal and trochanteral fields, subcapitulum and papal femur and genu are punctate and show a faint reticulation pattern (at the slightly deeper focal plane). This was not noted in the original description, but Fig. 4 shows a photograph of the holotype and a Turkish specimen. Coxae II is bigger than other coxae and anterolateral portions have no punctation.
