Figs. 1–8
Dendroseius amoliensis resembles D. badenhorsti (Ryke, 1962) closely. The new species is distinguished from the other in having 5 pairs of setae on ventrianal shield instead of 6, ventrianal shield roughly triangular instead of quadratic, peritreme anteriorly reaches to the level of mid­coxa III instead of reaching to the level of anterior margin of coxa II, peritreme situated on a slightly wide peritremal plate instead of a narrow peritremal plate, shorter middle prong of tectum and reticulated over entire dorsal shield.
Female (n=5). Dorsal idiosoma. (Fig. 1) — Dorsal shield divided 350 (357) long, 173 (170) wide at I1; reticulate over entire surface; bears 36 pairs of dorsal setae, 19 pairs on each anterior and posterior dorsal shield; all dorsal setae simple; lateral membrane with 4 pairs of simple marginal setae of r5­7 and R1; length of dorsal setae: i1 19 (18), i2 22 (22), i3 20 (20), i4 20 (19), i5 19 (19), I1 23 (22), I2 24 (23), I3 23 (23), I4 24 (24), I5 20 (19), z1 22 (21), z2 20 (20), z3 22 (21), z4 20 (20), z5 21 (21), Z1, Z2 23 (23), Z3 23 (24), Z4 28 (28), Z5 40 (40), s1 20 (20), s2 21 (21), s3, s4 22 (22), s5 21 (21), S1 21 (22), S2 23 (23), S3 22 (23), S4 26 (26), S5 29 (29), r1 12 (11), r2 18 (18), r3 20 (20), r4, r6 18 (18), r5 28 (27), r7 19 (19), R1 15 (16), R2 21 (21), R3 20 (20), R4 20 (21), R5 22 (23); anterior and posterior dorsal shields with 1 and 5 pairs of visible pores respectively; two pairs of scleronoduli are located between i4 and i5; anterior margin of posterior dorsal shield with two pairs of small incisions (this feature is clearly recognizable in the holotype and one of the paratypes).
Ventral idiosoma. (Fig. 2) — All ventral setae simple; tritosternum 65 (67) with paired laciniae and pilose with slightly short piles, free for more than half of total length; sternal shield divided, anterior part weakly sclerotized bearing setae ST1 27 (28), posterior part sclerotized and slightly reticulated with 3 pairs of setae of ST2 27 (27), ST3, ST4 24 (24) and 3 pairs of pores, length of sternal shield (including anterior part) 103 (104), excluding anterior part 75 (75) long at midline, width at the level of ST2 55 (56) long; epigynial shield truncate posteriorly and slightly reticulated, 55 (55) wide at the level of ST5, with a pair of simple setae ST5 21 (22), paragenital pores in soft cuticle posterior to ST5; slender platelets located between epigynal and ventrianal shields; ventrianal shield roughly triangular and reticulated 112 (116) long and 125 (123) wide, with 5 pairs of setae of JV1 17 (17), JV2, JV3 20 (20), ZV2 19 (19), para­anal setae 33 (32) and post­anal seta 17 (18); anus 17 (18) long; ZV1 17 (17), ZV3 20 (20), JV4 26 (25) and two pairs of small round platelets on soft cuticle surrounding anal shield; metapodal plate 26 (25) long; ventral shields are also faintly punctate; peritreme short on a s­shaped and slightly wide plate, peritreme extending to the level of mid­coxa III, two pores located posteriorly to peritremal plate on soft cuticle; Fig. 5 shows the gonoporus associated with coxa leg IV.
Gnathosoma. Tectum (Fig. 3) with three pointed prongs, middle prong 14 (13) shorter than the lateral prongs 18 (17); hypostome (Fig. 6 and 7) with seven rows, six rows with hypognathal denticles most bearing some tiny denticles (the denticles of first row in holotype is not well recognizable, Fig. 7); capitular setae 20 (20), internal posterior rostral setae 19 (20), external 14 (13), and rostral setae 23 (22), all simple; corniculi horn­like and not divided; chelicera (Fig. 4) with fixed digit 35 long and a row of 5 teeth, movable digit 37 long and with 3 teeth; palp apotele two­tined.
Legs. Leg I 335 (323), leg II 250 (253), leg III 228 (222), leg IV 305 (304); setation of legs I­II­III­IV: coxae 2­2­2­1, trochanters 6­5­5­5, femora 13­10­6­6, genua 12­11­9­7, tibiae 12­10­8­7; genua and tibiae leg IV without any macrosetae (Fig. 8).
