The specific epithet ‘salicornicus’ is derived from the species name of the host plant “ Haloxylon salicornicum ”.</p><p>Remarks. The armenychus species group in the genus Tetranychus Dufour is characterised by entirely transverse dorsocentral hysterosomal striations (Flechtmann and Knihinicki 2002). Currently, this group includes only seven species: T. armeniaca Bagdasarian, T. cobrensis Baker and Tuttle, T. iraniensis Mahdavi et al., T. graminae Flechtmann, T. mcdanieli McGregor, T. pacificus McGregor and T. rhagodiae Miller (Flechtmann and Knihinicki 2002; Flechtmann and Navia 2007; Mahdavi et al. 2013). The new species T. salicornicus sp. nov. closely resembles T. pacificus and T. mcdanieli because all three species have a similar angled aedeagus with long posterior projection of head. The new species differs from the males of T. pacificus and T. mcdanieli by posterior projection of aedeagus head strongly turned downward distally vs not turned downward distally, tapered and straight, length of posterior projection almost equal to or slightly longer than the width of aedeagus neck vs posterior projection 2 – 2.5 times longer than the width of aedeagus neck; and from the female of the new species by its pregenital area with complete transverse and oblique striae vs irregular, sparse medially and incomplete/vague in T. pacificus or broken longitudinal in T. mcdanieli . The new species also differs from females of T. pacificus by dorsal striations without lobes vs with lobes in T. pacificus .</p><p>Type material</p><p>Holotype female and 17 paratypes (15 females, two males), Salsola imbricata, ( Amaranthaceae), College of Food and Agriculture Sciences, <a href="https://tb.plazi.org/GgServer/search?materialsCitation.longitude=46.440956&amp;materialsCitation.latitude=24.53138" title="Search Plazi for locations around (long 46.440956/lat 24.53138)">King Saud University</a>, Riyadh, 24°43 ʹ 30.687N, 46°36 ʹ 30.404E, 11 December 2014; paratypes: (nine females, three males), Haloxylon salicornicum, Salbookh <a href="https://tb.plazi.org/GgServer/search?materialsCitation.longitude=46.440956&amp;materialsCitation.latitude=24.53138" title="Search Plazi for locations around (long 46.440956/lat 24.53138)">Road</a>, near <a href="https://tb.plazi.org/GgServer/search?materialsCitation.longitude=46.440956&amp;materialsCitation.latitude=24.53138" title="Search Plazi for locations around (long 46.440956/lat 24.53138)">Dariyah</a>, Riyadh, SA, 24° 50.57′N, 46°33.149′E, 21 September 12 October 2012; three females, H. salicornicum, Makkah road near police checkpost, Riyadh, 24º31 52.97N, 46º26 27.44E, 18 October 2012; all collected by M.
