Anoplocheylus bonabjadidiensis Navaei-Bonab n. sp.

( Figures 1-2 )

Female (n = 2) — Measurements of holotype (measurements of paratype in parentheses): length of body (including gnathosoma) 650 (580), (excluding gnathosoma) 525 (440), width 225 (205); length of leg I 460 (465), leg II 270 (250), leg III 355 (305), leg IV 440 (405).

Gnathosoma ( Figure 1b, c ) — Subcapitulum with 4 pairs of setae, subcapitular setae much longer than adoral setae; chelicerae not fused and each with 2 setae, proximal seta 35 (31) long; palp 4- segmented, trochanter and coxa fused; femur with 4 simple setae; short genu with 2 setae; tibiotarsus with terminal claw, 2 subapical spurs, 1 falcate seta and 9 simple setae.

Dorsum ( Figure 1d ) — Peritremes in membrane connecting gnathosoma and idiosoma with distal half chambered; prodorsal shield with one pair of claviform sensillae ( Figure 1e ) 70 (65) long and five pairs of simple setae with posterior pair very long 145 (150); length of setae between sensillae 70 (65); hysterosoma striated and with 17 pairs of setae with setae d3 150 (145) and (f1) 120 (131) very long.

Venter ( Figure 1f ) — With 15 pairs of subequal setae; with 2 pairs of setae between coxae I; 3 pairs of aggenital setae plus 3 pairs of genital setae; pseudanal shields terminal and with 2 pairs of pseudanal setae, one pair (ps1) dorsal and other pair (ps2) ventral; length of ps1 23 (21) and ps2 52 (50).

Legs ( Figure 2 ) — legs with pretarsi stalked, annulated, bearing a pliable empodium without claws; chaetotaxy of leg segments as follows (solenidia and seta κ included): tarsi 22(ω)-8(ω)-9- 9, tibiae 11(ω,κ)-5-5-5, genua 7-5-4-5, telofemora 6- 3-3-3, basifemora 6-2-2-2, trochanters 1-2-2-1, coxae 4-3-3-2.

Etymology — This species is named after the town, Bonab-E-Jadid, where it was collected.

Other stages — Unknown

Type material — Holotype female and one paratype female were collected from soil under apple trees of Marand , East Azerbaijan province , 4 August, 2009, by Reza Navaei-Bonab . Holotype is deposited in the mite collection of the ARC- Plant Protection Research Institute, Pretoria, South Africa. The paratype is deposited in the Collection of the Acarology Laboratory , University of Maragheh, Maragheh, Iran .

Differential diagnosis — Anoplocheylus bonabjadidiensis closely resembles A. malayeriensis Ueckermann and Khanjani 2004 and A. clavatus Baker and Atyeo 1964 in having setae (sc1) claviform and 5 pairs of simple setae on prodorsal shield; d3 (?) and f1 (?) the longest hysterosomal setae and at least 15 pairs of seta on hysterosoma.

However, A. bonabjadidiensis can be distinguished from A. clavatus by:

1. sensillae claviform slender vs. broad in A. clavatus;

2. sensillae as long as pair of setae between them vs. twice as long in A. clavatus;

3. proximal setae 35 (31) long vs. 44 – 47 in A. clavatus.

also, the new species can be distinguished from A. malayeriensis by:

1. sensillae claviform as long as pair of setae between them vs. less than twice its length in A. malayeriensis ;

2. length of f1 on posterior third of hysterosoma 120 (131) vs. 69 long A. malayeriensis ;

3. proximal setae 35 (31) long vs. 44 – 47 in A. malayeriensis ;

4. length of humeral setae (d3) 150 (145) vs. 120- 125 in A. malayeriensis ;

5. leg chaetotaxy, except for coxae and telofemora, also differs in these two species.

In the new species tarsus II, tibia IV, genu IV, basifemora I-III and trochanter II with 8, 5, 5, 6, 2, 2 and 2 setae (included solenidia) vs. 9, 6 or 7, 4, 8, 3, 3 and 1 setae in A. malayeriensis .
