Type specimens. Holotype female (Acarol.lab/ BCKV/8649/2021) deposited in the NZC, Zoological Survey of India, Kolkata, collected from Moss at East Sikkim: 27°22’52”N 88°38’15”E, 1732 m AMSL, East Sikkim, Sikkim on 29 th March, 2021. 2 paratype females collected on 29 th March, 2021 (Acarol.lab/ BCKV/8649/2021) with same locality and host plant as holotype. 2 paratype males collected on 25 th February, 2021 (Acarol.lab/ BCKV/8650– 51/2021) with same locality and host plant as holotype.
Etymology. The specific name himaliniae dedicated to the name of Goddess Parvati, better half of God Shiva resides in the Great Himalaya.
Remarks. The T. (Anthoseius) himaliniae sp. nov. is close to T. (A.) gopali Gupta, 1969a; T. (A.) orissaensis Gupta, 1977; T. (A.) xini (Wu, 1983) and T. (A.) transvaalensis (Nesbitt, 1951) by having similar type of dorsum and venter but differs from these close species by the length and form of dorsal setae; ventrianal shield; number of teeths in fixed and movable digit of chelicera; length and form of leg macrosetae. All the differences are presented in Table 8.
