FB4503238536F542FF6AF8566173C897.taxon	description	Gnathosoma (Fig. 2) – Gnathosoma hidden beneath anterior end of idiosoma; with a horse-shoe like, dentate oral ring, hypostomal setae (bs) conical in shape, adoral setae (cs) short and pointed; chelicerae robust; cheliceral blade sickled-shaped with one tooth subterminally, 21 – 24 long. Palp femur and genu, each with one nude spine-like seta. Palp tibia with three nude setae; one long, the others short, and one is close to the tibial claw (paradont). Palp tibial claw bifurcate. Palptarsus with six nude setae (four are long, the others are spine-like), a solenidion and an eupathidium. fPp = 0 - N- N-NNN 2 - 6 Nωζ. Legs (Figs. 3 A – C) – Leg segmentation formula 6 – 6 – 6. Leg setal formula: Leg I: Ta - 1 ω, 1 ε, 2 ζ, 18 n; Ti - 2 φ, 1 κ, 6 n; Ge - 2 σ, 1 κ, 4 n; Fe - 6 n; Tr - 1 n; Cx - 2 n (Figs. 2, 3 A); Leg II: Ta - 1 ω, 1 ε, 1 ζ, 14 n; Ti - 2 φ, 5 n; Ge - lσ, 1 κ, 2 n; Fe - 5 n; Tr - 1 n; Cx - 1 n (Figs. 2, 3 B); Leg III: Ta - 13 n; Ti - 5 n; Ge - l σ, 2 n; Fe - 4 n; Tr - 1 n; Cx - 1 n (Figs. 2, 3 C). Tarsi I & II with two normal claws and a claw-like empodium. Tarsal empodium elongate, longer than claws. Ta III outer claw normal, but its inner claw has been modified into smilum. Tarsus III with one scopa (with eight setules in the holotype and two of the paratypes and seven setules in the other new material) and a 10 - branched lophotrix. Metric data is given in Table 1.

All specimens and the grasshopper hosts deposited in the Acarological Collection of the Department of Entomology, Faculty of Agriculture, Tarbiat Modares University (ACTMU), Tehran, Iran. Taxonomic notes We examined the type specimens of E. tehranicum, E. fathipouri and E. elburzensis, which were collected from Tehran and Alborz proviences of Iran, two geographically close regions. Karimi Iravanlou et al. (2000) reported the following diagnostic characteristics for these species: Eutrombidium fathipouri: Five normal setae on Fe I, one solenidion on each Ti I and Ge I, four normal setae on Ti II, three normal setae on Ge II, three normal setae on Ge III. Eutrombidium elburzensis: Five normal setae on Fe I, one solenidion on each Ti I and Ge I, two solenidia on Ti II, one normal seta on Ge II and the absence of setae c 2 on dorsal idiosoma. However, after examining the type specimens, we found that both species share the following characteristics: Six normal setae on Fe I, two solenidia on each Ti I and Ge I, five normal setae on Ti II, two normal setae on each Ge II and III, and the presence of setae c 2. Additionally, several metric data in the original descriptions were found to be incorrect; corrected values are marked with an asterisk in Table 1. Based on these findings, and ICZN Article 24.2 (ICZN, 1999), we propose the following synonymy: Eutrombidium fathipouri syn. nov. of E. tehranicum. Eutrombidium elburzensis syn. nov. of E. tehranicum.
