We have identified the species Tetranychus lintearius Dufour, 1832 from Amaranthus, Amaranthus cruentus L. ( Amaranthaceae) by comparing the structure of aedeagus, tarsus of leg I and II mainly the number of setae proximal to the proximal duplex setae, pregenital striation pattern of female and shape of dorsal palp femoral seta. A detailed complimentary description of the species has been provided in addition to earlier descriptions and illustrations. Seeman and Beard, 2011 stated that the peritreme hook length of females is 19–22 but here peritreme hook length is 25–27. We have redescribed the species with proper measurements. This species is reported for the first time from India.</p></div>	https://treatment.plazi.org/id/063BDD37FFA0FFB5730E7E1251DDC301	Public Domain	No known copyright restrictions apply.
