Material examined

One (ARS-20220503-2a) larva was collected ectoparasitic on C. coreanus ( Hemiptera : Pentatomidae ), IRAN: South Khorasan Province, Birjand city, Khosf region, Shahrestanak village (33° 15.39′ N, 59° 43.03′ E, 2111 m a.s.l.), 17 June 2020, one larva (ARS-20220503-2b), from Darmiyan region, Khan village (32° 41.57′ N, 59° 13.58′ E, 1893 m a.s.l.), from soil and litter, 10 July 2020, coll. Mahnaz Kohansal ; one larva (ARS-20220503-2c), from Giuk village (32° 47.31ʹ N, 59° 07.33ʹ E, 1961 m a.s.l.) from soil and litter, 17 May 2019 , and one larva (ARS-20220503-2d), from Chahkand village (32° 49.55′ N, 59° 09.37′ E, 1716 m a.s.l.) from soil and litter, 31 May 2019, coll. Javad Noei. Two specimens (ARS-20220503-2a–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 (ARS-20220503-2c–1d) are deposited in the Acarological Collection, Acarological Society of Iran, Department of Plant Protection , Faculty of Agriculture , University of Tehran, Karaj, Iran .

Some details about the gnathosoma (cheliceral blade, anterior hypostomalae, dorsal surface of cheliceral bases, palpal supracoxal seta), dorsal and ventral surface of idiosoma (present small plates, supracoxal seta on Coxa I, a punctate area attached to the coxae II) are not mentioned and illustrated in Haitlinger and Saboori (1996) and Saboori and Atamehr (2000). Based on the material examined in the present study, complementary data to the species characteristics are as follows:

Dorsum ( Figs. 1, 2 ) – Dorsum of idiosoma with 87–88 barbed setae of which three pairs are around the scutum (two pairs lateral to scutum and anterior to eyes, and one pair between eyes and scutum). All dorsal setae with fine barbs and arising from small plates. Scutum triangular in shap, punctate, with two pairs of sensilla (ASens and PSens) and two pairs of normal setae (AL and PL). PSens longer than ASens, both barbed at distal one-third. AL and PL subequal, both barbed. Posterolaterally on each side of scutum one eye (diameter 25–27).

Venter ( Figs. 3, 4 ) – Idiosoma ventrally with five pair of sternal setae (1a, 2a 1, 2a 2, 3a 1, 3a 2) and four barbed setae between coxae I and II; 47–49 setae between coxae II and III (excluding 2a 1, 2a 2, 3a 1 and 3a 2), a punctate area is attached to the coxae II; 45–50 setae behind coxae III (excluding 3a 1 and 3a 2), all ventral setae with fine barbs, pointed, and arising from small plates. Each leg coxa with one barbed seta. A peg-like supracoxal seta (elcI) present on coxa I, 3–5 long. NDV = 181–184.

Gnathosoma ( Figs. 5, 6 ) – Cheliceral bases punctate on dorsal surface, cheliceral base 85–91 long; cheliceral blade slightly curved, 20 long, with a subterminal tooth. Subcapitulum with a barbed galealae (cs) and two hypostomalae, anterior (as) minute and posterior barbed (bs); palp femur 35–37 long, with one dorsal and one ventral seta, both barbed and palp genu 21–25 long, with one dorsal and one ventral seta, both barbed. Palp tibia 22–25 long, with three setae including two barbed, and one nude conical seta (i.e. thick accessory claw); palpal tibial claw bifurcate 25–28; palp tarsus 10 in length, with six nude setae, one solenidion and one eupathidium; fPp = 0-BB-BB- BBN 2 -6Nωζ. Palpal supracoxal seta (elcP) peg-like, 3–4 long.

Legs ( Figs. 7–12 ) – Leg segmentation formula 7-7-7. Leg setal formula: Leg I: Ta– 1ω, 1ɛ, 2ζ, 1 z, 25n (24n in one specimen ARS-20220503-2d); Ti– 2φ, 1Ƙ, 13n; Ge– 10, 1Ƙ, 11n; TFe– 8n; BFe– 5n; Tr– 2n; Cx– 1n ( Figs. 7–8 ). Leg II: Ta– 1ω, 2ζ, 1 z, 21n (20n in one side of symmetry axis in ARS-20220503-2a); Ti– 2φ, 13n; Ge–10, 1Ƙ, 9n; TFe– 5n; BFe– 5n; Tr– 2n; Cx– 1n ( Figs. 9– 10 ). Leg III: Ta– 1ζ, 22n (21n in one side of symmetry axis in two specimens, ARS-20220503-2b, 2c); Ti– 1φ, 13n; Ge– 10, 9n; TFe– 5n; BFe– 5n; Tr– 2n; Cx– 1n ( Figs. 11–12 ). Each leg tarsus with lateral falciform claws and a claw-like empodium. Metric data are given in Table 2 .
