Holotype female (macroptera), INDIA, Himachal Pradesh, Chamba District: Dalhousie: BaraPathar, (32 º 31 '52.0" N 76 º00'04.0'E, 2231 m) from ferns, 11.x. 2013, Vikas & Kaomud (Reg. 5856 /H 17). Paratypes: 2 females with same data as holotype, (Registration No. 5857 / H 17 to 5858 /H 17). Holotype and paratypes deposited in the National Zoological Collections (NZC), Zoological Survey of India, Kolkata, India. Etymology. This new species is named after its type locality. Comments. This new species is remarkable for the structure associated with the first ocellus, and for the position of ocellar setae pair III posterior to the triangle. It is similar to C. transeolinae (Chen) in sharing the following characters: colour of antennal segments, shape of head and position of ocellar setae III. It differs in the following characters: presence of a dark thickenings attached to the fore ocellus; postocular setae II longest and arising posterior to setae I; median pronotal setae at posterior margin longer than submedian; distance between median pair of metanotal setae subequal to the distance between median and submedian; abdominal tergites I–VII smooth at posterior margin. In contrast, transeolinae has: absence of dark thickening attached to fore ocellus; poII ahead of poI, all head setae subequal; median pronotal setae at posterior margin shorter than submedian setae; distance between median pair of metanotal setae greater than distance between median and submedian; abdominal tergites I–VII with polygonal reticulation at posterior margin.Published as part of Tyagi, Kaomud, Ghosh, Biswatosh & Kumar, Vikas, 2014, The genus Ctenothrips from India (Thysanoptera: Thripidae) with description of one new species and one new record, pp. 273-279 in Zootaxa 3821 (3) on page 274, DOI: 10.11646/zootaxa.3821.2.7, http://zenodo.org/record/22543
