Based on taxonomic procedure for this particular group of mite, descriptions of the newly found mite species are discussed elaborately here to establish the new species of the genus Paratetra and relation to the host plant is also mentioned here. The etymology of the new name of the species is given following the Nomenclature Rules of International Code of Zoological Nomenclature. Paratetra subhimalyana. on Murrya koengii (Fig 1) is found new to science as this species has following unique taxonomic characteristics.

Male: Not found
Holotype and Paratype record: Female (marked) on slide (no.1382/79/2019), India: West Bengal: Malda, Englishbazar, 14.x.2019. from Murrya koengii Spr. (Rutaceae )Coll. S. Sarkar. Paratypes: 9 females on slide bearing holotype and 48 females on 6 slides (nos. 1383-1388/85/2019); collection data same as in holotype.
Nature of damage: Mites are found Vagrants on tender shoots including leaves; may cause some browning of leaves. Infested leaves fall off eventually. Shoot becomes dry.
Diagnosis as a new species: So far, 6 species including 5 species from India under the genus Paratetra are known  (Amrine et. al., 2003). The new species resembles P. elephantae and in having 5 rayed tarsal empodium and longitudinal scrings on epigynium, but differs from P. elephantae not having median longitudinal fold on prodorsal shield. The new species also resembles P. integrifoliavagrance in absence of median lines and having similar dorsal trough on opisthosoma but differs from it by having 5 rayed tarsal empodium (in P. integrifoliavagrance it is 4 rayed) and not having any granulation on the prodorsal shield and on epigynium base. The new species shows very close resemblance with P. murrayae by sharing common host plant, 5 rayed tarsal empodium. but differs from P. murrayae by sculpture of prodorsal shield in details, by presence of longitudinal scorings on lateral sides of first 3 dorsal annuli, presence of knob like structures at the tip of scapular setae and dorsal pedipalp genual seta d. Presence of longitudinal scorings on lateral side of first 3-4 dorsal annuli, longitudinal scorings at joint between coax and femur and femur and genu and prodorsal shield pattern make the species a new.
Etymology of new name: The specific epithet ‘subhimalyana’ derived from the geographical location of the collection area of the mite. As the area Englishbazar of Malda district is situated in the Sub-Himalayan region (25° 0' 39.0276'' N and 88° 8' 27.9528'' E)
