description: Charletonia damavandica Karimi Irvanlou, Kamali & Talebi, 2002 (Figs. 1–15)
Syn.: Charletonia saboorii Karimi Irvanlou, Kamali & Talebi, 2002
Diagnosis
Two setae between coxae II and III, solenidion on Ge I placed in distal half after or at the same level as the most distal normal seta, 220> Ti III> 150, galealae normal (setiform) with 5–8 long ciliations and hypostomalae barbed.
Redescription
Larva (N = 10) – Dorsal surface with 32 barbed and pointed setae; scutum pentagonal, punctate and longer than wide; lateral parts of anterior border slightly concave, median part convex, lateral borders slightly convex; posterior border convex except median part which is concave; scutum with two pairs of sensilla and three pairs of normal setae. AL, ML and PL barbed and pointed. Posterior sensilla (PSens) longer than anterior sensilla (ASens); ASens and PSens with short barbs in distal 1/3 (Fig. 1). One eye on each side of idiosoma, 25 in diameter.
Ventral surface of idiosoma with 18 barbed and pointed setae behind coxae III (fV). Sternalae 1a (between coxae I), 2a (between coxae II) and 3a (between coxae II and III) barbed and pointed. NDV = 32 + 18 = 50. Coxa I with one seta (1b); coxae II & III, each with two setae. All coxalae barbed and pointed (Fig. 2).
Subcapitulum with a galeala (cs) and two hypostomalae (as, bs), galealae normal (setiform) with 5–8 long cilia, hypostomalae barbed (Fig. 3). Palpal femur and genu each with one barbed and pointed seta; palpal tibia with three pointed and barbed setae (Fig. 3); palpal tibial claw bifurcate. Palpal tarsus with five barbed setae, one solenidion and one eupathidium (Fig. 3). fPp = 0-B-BBBB 2 -5B . Cheliceral basis punctate. Supracoxal seta peg-like, 4–5 long.
Leg segmentation formula: 7–7–7. Leg setal formula: Leg I: Ta – 1 , 1 , 2 , 1Cp, 29n; Ti – 2φ, 1Cp, 1 , 18n; Ge – 1 , 1 , 12n; TFe – 5n; BFe – 4n; Tr – 1n (Figs. 4–7). Leg II: Ta – 1 , 1 , 30n; Ti – 2 φ, 18n; Ge – 1 , 12n; TFe – 5n; BFe – 4n; Tr – 1n (Figs. 8–11). Leg III: Ta – 1 , 30n; Ti – 1 φ, 18n; Ge – 12n; TFe – 5n; BFe – 2n; Tr – 1n (Figs. 12–15). Lengths of solenidion on Ta I: 19–23.
Measurements and also the corrected metric data of the specimen described as C. saboorii are given in Table 1.

Additional material examined
Four larvae of C. damavandica (JAZM-AC-Er-0566a, b, c, d), on one female of Calliptamus italicus L., Shahrood city (36° 22′ 27.54′′ N, 54° 54′ 50.08′′ E, 1317 m a.s.l.), Semnan province, Iran, 6 August 2018, col.

Two specimens (JAZM-AC-Er-0566a & b) are deposited in the Acarological Collection, Jalal Afshar Zoological Museum, Department of Plant Protection, Faculty of Agriculture, University of Tehran, Karaj, Iran and two specimens (JAZMAC-Er-0566c & d) are deposited in the Acarological Collection, Acarological Society of Iran, Department of Plant Protection, Faculty of Agriculture, University of Tehran, Karaj, Iran.
Remarks
This species belongs to the species group of Charletonia with two setae between coxae II–III, one of the solenidia on Ti II placed on the proximal half of the segment, solenidion on Ge I placed distal or at the same level as the most distal seta, solenidion on Ta I up to 1/5 length of Ta I, fn Ge I–III 12–12–12, 230> Ti III> 110. There are seven species in this group, as follows: C. kalithensis and C. kosensis both from Greece, C. austisensis from Italy, C. damavandica, C. behbahanensis and C. behshahriensis, all from Iran.
Charletonia damavandica differs from C. kalithensis by longer Ti III (183–217 vs. 114–120), Ta I (130–180 vs. 84–90), Ta II (126–165 vs. 74–76), Ta III (141–182 vs. 78–80), and fD (32–36 vs. 84); from C. kosensis by shorter solenidion on Ta I (19–23 vs. 45–50), anteromedian border of scutum convex (vs. anterior border almost straight), shape of galealae and hypostomalae (barbed vs. nude); from C. austisensis by shape of galealae and hypostomalae (barbed vs. nude), solenidion on Ge I placed at the same level as the most distal normal seta (vs. after the most distal normal seta), from C. behbahanensis by shape of galealae and hypostomalae (barbed vs. nude), one seta present between eye and scutum (vs. without setae between eye and scutum), from C. behshahriensis by galealae normal with 5–8 long cilia (vs. galealae cone-like with several short cilia), solenidion on Ge I placed at the same level as the most distal normal seta (vs. solenidion on Ge I placed distinctly after the most distal normal setae).
