Distribution

Iran (Pesic et al., 2004). It is newly recorded species for the Turkish fauna.

Remarks

The male of T. persica is described for the first time in this study. Pesic et al. (2004) described T. (Megapalpis) persica Pesic, 2004 based on a female from Fars province ( Iran). This species can be distinguished from all other Palaearctic species by the excretory pore fused with the area of primary sclerotization. It differs from T. thori from the short cheliceral claw. The male T. persica differs from T. fagei in the dorsal shield length/width ratio (1.3.-1.5) and P-2/P-4 ratio (1.3-1.4). T. persica differs from T. tenuirostris by the relatively short cheliceral claw (ratio basal segment/claw <4). T. persica differs from T. remyi in the combination of an elongated idiosoma (1.35-1.4), and short cheliceral claw (ratio basal segment/claw 4.8-4.9).
