The spider mite genus Neotetranychus Trägårdh is reported for the first time from Saudi Arabia (SA) based on N. longisetus n. sp., collected from Heliotropium arbainense (Boraginaceae). The new species is described and illustrated from the adult female, and three species, Mixonychus (Bakerina) aculus (Chaudhri), Paraplonobia (Anaplonobia) harteni (Meyer) and Sonotetranychus daleae (Tuttle and Baker) (Acari: Tetranychidae) are reported as new to the mite fauna of SA. Mixonychus (B.) aculus (Chaudhri) is re-described and illustrated based on adult female, collected from an exotic mesquite species from Mexico and Caribbean, Prosopis juliflora (Sw.) DC. (Fabaceae). Moreover, the species, Evertella orissaensis (Prasad) n. comb., is moved from the genus Mixonychus Ryke and Meyer to the genus Evertella Meyer and Mixonychus (Bakerina) ganjuis (Qian, Yuan and Ma) n. comb., is moved to the subgenus Bakerina Chaudhri from the subgenus Mixonychus. A key to the world species of the genus Mixonychus is also provided. Additionally, legs chaetotaxy of all known species of the genus Mixonychus is given.

“…In many genera of the tribe Tetranychini Reck, three pairs of h setae ( h 1 , h 2 , and h 3 ) are consistently present on the fifth segment (H) of opisthosoma ( Pritchard and Baker 1955 ; Lindquist 1985 ; Bolland et al 1998 ). However, one of these setae ( h 1 or the clunals) is absent in some Tetranychini genera, e.g., Oligonychus and Tetranychus ( Pritchard and Baker 1955 ; Lindquist 1985 ; Bolland et al 1998 ; Seeman and Beard 2011 ; Alatawi and Kamran 2018 ; Khanjani et al 2018 ). Earlier, Pritchard and Baker (1955) believed that seta h 1 (clunal seta) is consistently present and h 2 (one of a pair of para-anal setae displaced terminally to become a post anal seta) is absent in Oligonychus .…”

“…Thus the setae are named as one pair of clunals and two pair of para-anals, and as a consequence, the statement "one pair of para-anal setae is present in Oligonychus and related genera" appears to be contradictory to what other authors believe. Many authors also mention the presence of h 1 and only one pair of para-anal setae (either h 2 or h 3 ) in the genus diagnosis and descriptions/illustrations of different Oligonychus species (Rimando 1962;Tuttle and Baker 1968;Chaudhri et al 1974;Meyer 1974;Jeppson et al 1975;Tuttle et al 1976;Zaher et al 1982;Tseng 1990;Gupta and Gupta 1994;Smiley and Baker 1995;Ehara 1999;Knihinicki and Flechtmann 1999;Flechtmann and Etienne 2006;Ehara and Gotoh 2007;Zeity 2015Zeity , 2016Alatawi and Kamran 2018).…”

A comprehensive taxonomic assessment of the most agriculturally important and highly diverse spider mite genus, Oligonychus Berlese (Acari: Tetranychidae) was performed. The sub-generic division, species groups, doubtful species, species complexes and the interpretation of a key generic character are discussed. Based on the orientation of the male aedeagus, only two subgenera, namely Oligonychus Berlese (aedeagus downturned) and Reckiella Tuttle & Baker (aedeagus upturned), are valid in the genus Oligonychus. The subgenera Homonychus Wainstein, Metatetranychoides Wainstein, and Wainsteiniella Tuttle & Baker are considered to be synonyms of the subgenus Oligonychus, whereas the subgenus Pritchardinychus Wainstein is proposed as a synonym of the subgenus Reckiella. Moreover, based on female morphological characters, four species groups (coffeae, exsiccator, iseilemae, and peruvianus) and 11 species subgroups (aceris, biharensis, coffeae, comptus, exsiccator, gossypii, iseilemae, peruvianus, pritchardi, smithi, and subnudus) are suggested in the subgenera Oligonychus and Reckiella. Fourteen Oligonychus species are proposed as species inquirendae, and potential cryptic species complexes in the genus Oligonychus are briefly highlighted. It is agreed that the clunal seta h1 is always absent, while the para-anal setae h2 and h3 are always present in the genus Oligonychus. A key to subgenera, species groups, and species subgroups of the genus Oligonychus is provided.

To elucidate the taxonomic problems in species delineation within the Oligonychus punicae complex (O. punicae, O. mangiferus, and O. vitis) (Acari: Prostigmata: Tetranychidae), we performed morphological and molecular investigations on mite samples, collected from different hosts/countries. Thirty-nine samples of punicae complex, collected from Egypt, Pakistan, and Saudi Arabia (SA), did not show any considerable morphological differences in females and males. All 39 samples of the punicae complex resembled the original description of O. punicae, while the claimed Mexican O. punicae was distinctively different based on male aedeagus. Molecularly, the low nucleotide diversity ranged from 0% to 2.1% (ITS2-rDNA) and 0% to 1% (COI-mtDNA), and was observed among various DNA sequences of the punicae complex from Egypt, India, Israel, Pakistan, and SA, confirming their identity as one species. The high genetic divergence ranged from 17.2% to 18.8% (ITS2) and 9.2% to 10.2% (COI), observed between the claimed Mexican O. punicae and all other sequences of the punicae complex, indicating that the Mexican sample do not belong to O. punicae. Basing our findings on both morphological and molecular data, we can conclude that O. mangiferus and O. vitis are synonymized with O. punicae. Additionally, this study reveals that the claimed Mexican O. punicae needs to be re-identified.
