Treatment

Cicaditrombium lorestanensis Noei sp. nov. ( Figs. 1–11 View Figures 1–2 View Figure 3 View Figures 4‒5 View Figures 6‒ 7 View Figures 8‒9 View Figures 10‒ 11 )

Diagnosis of larva – AL scutalae and pedocoxalae 2a, 2b and 3b thick, spear-like, tapering and pointed.

Description of larva (n = 3)

Dorsum ( Figs. 1, 2 View Figures 1–2 ) – Idiosoma 267–305 long and 135–157 wide. Dorsum of idiosoma with 26 dorsal barbed setae, each arise from a punctate raised sclerite, arranged in 5 rows, fD = 4 (+2)-6-4-6- 4 = 24 (+2): c 1–3, d 1–3, e 1–2, f 1–3 and h 1–2 ( Figs. 1 View Figures 1–2 , 3 View Figure 3 ). Scutum semipentagonal, bearing 3 pairs of normal setae (AM, AL and PL) and one pair of sensilla (S). Setae AL thick, spear-like, tapering, pointed and shorter than AM and PL, all scutalae barbed. Sensilla relatively long and barbed in distal half. Scutum rounded anteriorly, posterior border slightly convex, punctate from posterior border to level of AM bases and with striations from posterior border extended between PL and S to just anterior to AL and behind tear-like ornamentation in lateral side ( Figs. 1, 2 View Figures 1–2 ), tear-like ornamentation between AM and AL setae on each side, anterior borders of scutum (between tear-like ornamentation and AM seta on each side) concave, lateral borders approximately parallel; posterolaterally on each side of scutum 2 eyes situated on common ocular plate (25–27 long, 18–21 wide), anterior lens (diameter 11) slightly larger than posterior one (diameter 7–8).

Venter ( Fig. 3 View Figure 3 ) – Idiosoma ventrally with one pair of barbed sternal setae (3a) and 2 pairs of ventral setae (fV) behind coxa III, and a uropore. Coxa I with proximal seta 1a and distal anterolateral seta 1b; coxa II with approximately medially seta 2a and distal medially seta 2b; coxa III with seta 3b approximately medially; 2a, 2b and 3b setae, all thick, spear-like, tapering and pointed; all coxalae barbed; coxae I–III each punctate. Claparède's organs between coxae I and II, oval. NDV = 24 (+2) + 4 = 28 (+2).

Gnathosoma ( Figs. 4, 5 View Figures 4‒5 ) – Cheliceral bases punctate on dorsal surface, cheliceral base 55–60 long; cheliceral blade slightly curved, 15–17 long, with a subterminal tooth. Adoral seta cs 3 long, arising from a pair of cuticular structures; one pair of barbed and thick subcapitular setae (bs), 9–11 long; palpfemur 25–28 and palpgenu 15–17 long, each without seta. Palptibia 12–14 long, with three nude seta; palpal tibial claw 9–11 and bifurcate; palptarsus 6–7 with 4 nude setae, one barbed seta and an eupathidium; fPp = 0-0-0-NNN 2 -BNNNNζ. Palpal supracoxal setae (elcp) peg-like, 4–6 long.

Legs ( Figs. 6–11 View Figures 6‒ 7 View Figures 8‒9 View Figures 10‒ 11 ) – Leg segmentation formula 6-6-6. Leg setal formula: Leg I: Ta – 1ω, 2ζ, 17n; Ti – 2φ, 1κ, 5n; Ge – 2σ, 1κ, 4n; Fe – 5n; Tr – 1n ( Figs. 6–7 View Figures 6‒ 7 ). Leg II: Ta – 1ω, 1ε, 14n; Ti – 2φ, 5n; Ge – 1σ, 1κ, 3n; Fe – 4n; Tr – 1n ( Figs. 8–9 View Figures 8‒9 ). Leg III: Ta – 13n; Ti – 5n; Ge – 1σ, 3n; Fe – 4n; Tr – 1n ( Figs. 10–11 View Figures 10‒ 11 ).

IP = 813–891. Metric data are given in Table 1.

Etymology The specific epithet is derived from the type locality, Lorestan Province, Iran.

Type material

The Holotype (ARS-20170305-2a) was collected from forest soils (off host), near a seasonal river, IRAN: South Khorasan province (Eastern Iran), Birjand city, Hotel Kouhestan region , 32° 49.40' N, 59° 10.48' E, 79 m a.s.l., 10 July 2016, coll. J. Noei; one paratype larva (ARS-20170305- 2b), same data as holotype except 18 June 2016; One paratype larva (ARS-20170305-2c) was collected from soil samples (off host) under an apple tree, IRAN: Lorestan province (Western Iran), Bayranshahr city, 48° 35.08' N, 33° 38.44' E, 1672 m a.s.l., 28 July 2013, coll. I. Hasanvand. GoogleMaps

Type deposition

The holotype and one paratype larvae (ARS-20170305-2a and 2b) are deposited in the Acarological Collection , Jalal Afshar Zoological Museum ( JAZM), Department of Plant Protection , Faculty of Agriculture , University of Tehran, Karaj, Iran , and one paratype larva (ARS-20170305- 2c) is deposited in the Acarological Collection , Acarological Society of Iran , Department of Plant Protection , Faculty of Agriculture, University of Tehran, Karaj, Iran .

Remarks

The new species belongs to the genus Cicaditrombium because has two median dorsal scuta; Ge II and III each with one solenidion; Ge I and Fe II with four normal setae; Ta III with short and thick inner claw; famulus absent on Ta I, present on Ta II; palpal supracoxal setae present. Cicaditrombium lorestanensis Noei sp. nov. is similar to Cicaditrombium weni Saboori and Lazarboni, 2008 . It differs from C. weni in the shape of AL scutalae and pedocoxalae 2a, 2b, 3b and bs (all thick, spear-like, tapering and pointed vs. normal in C. weni ), in shorter AL (18–19 vs. 20–25), 2a (about 21 vs. 25– 59), 2b (> 17–21 vs. 22–57), 3b (about 25 vs. 27–40), AW (60–65 vs. 71–77), PW (70–74 vs. 77– 82), SS (18–20 vs. 25–32), PDS Min. (30–43 vs. 42–50), PDS Max. (49–65 vs. 62–99) ( Tables 1, 2), subterminal sword-like and cone-like setae on Ta III (absent vs. present).

The two known species of Cicaditrombium larvae may be separated as follows:
