Ventral shield smooth and genital shield weakly expressed, with few transverse-tessellate striae ( Fig. 28 ); aggenital ( ag ) setae almost smooth and shorter than genital setae ( g1-2 ); inner pair ( g1 ) level with outer pair ( g2 ); anal setae ( ps1-3 ) shorter than genital setae, setae g1 23, g2 20, ps1 15, ps 2 24, ps3 13.

Rostrum normal and as indicated in Fig. 28 ; palp 4 segmented, with 1 solenidion and 2 eupathidia; palp tibia with 2 setae; palp femurogenu with 1 dorsal seta ( Fig. 31 ). Subcapitulum and chelicerae as in Figs. 30 and 32 , respectively. Legs ( Figs. 33-36 ). Setal formulae of leg I-IV segments as follows (numbers of solenidia in parentheses): coxae 2 – 2 – 1 – 1; trochanters 1 – 1 – 2 – 1; femora 4 – 4 – 2 – 1; genua 3 – 3 – 0 – 0; tibiae 4 – 4 – 3 – 3; tarsi 9(1) – 9(1) – 5 – 5. Tarsal claws pad-like, with tenent hairs. Legs chaetotaxy shown in Figs.33-36 . Male and immature stages. Unknown. Material examined. Holotype female from Alopecurus myosuroides Hudson (Poaceae) under apple trees, Malus domestica (L.) ( Rosaceae ), IRAN : Kermanshah province, Sahneh (34° 27ʹ 49.59ʹ N 47°40ʹ48ʹ E, alitude 1316 m a. s. l.), 3 July , 2010, coll. M. Khanjani. Type deposition . Holotype female–QMA. Etymology . The new species is named after the city name, Kermanshah, Iran , where it was collected. Remarks . Although this species is represented by only one specimen it is undoubtedly distinct from all other Pseudoleptus as it is the only species with the combination of 12 pairs of hysterosomal setae (seta f2 absent) and 4- segmented palps bearing a palp femoral seta. Furthermore, its combination of dorsal and ventral sculpturing, leg chaetotaxy and dorsal setal lengths is also unique. This species is closer to New World species of Pseudoleptus , as it lacks seta f2 , has smooth metapodosomal and opisthosomal shields, genu III without seta l ΄, and an obsolete ventral shield. Also P. kermanshahiensis sp. nov resembles P . zelihae Pritchard and Baker , 1958 in having the same number of hysterosomal setae, paired smooth metapodosomal shields and a smooth opisthosomal shield. However it differs from the latter by: palp femur-genu with one seta versus without seta P . zelihae ; palp tarsus with two eupathidia and one simple seta versus one eupathidium and one simple seta in P. z e l i h a e ; propodosoma medially with irregular, coarse striation versus regular longitudinal striae in P. z e l i h a e ; and opisthosomal venter with regions of tessellate sculpturing instead of mostly transverse undulate striae in P. zelihae .
