- Ctenothrips barapatharensis sp. n. Female (macroptera). Body dark black including coxae and femora; all tibiae and tarsi yellow; fore wing brown with sub-basal white band; antennal segments I–II and VI brown, remaining segments yellow (Fig. 3). Head reticulate, longer than wide, slightly produced in front, strongly constricted just behind eyes; with strong and dark thickenings attached to fore ocellus (Fig. 4); two pairs of ocellar setae present, pair I absent, III arising posterior to ocellar triangle; compound eyes swollen without pigmented facets; postocular setae not arranged in one row, pair I longest; mouthcone rounded at apex. Antennae 8 -segmented (Fig. 7); segments III and IV each with forked sense cones. Pronotum wider than long, transversely striate, with 11 discal setae, 2 pairs of posteromarginal setae inner to long major posteroangulars; median setae at posterior margin of pronotum longer than submedian setae (Fig. 4). Mesonotum with reticulate sculpture on anterior half but transverse striae on posterior half (Fig. 8); median pair of setae ahead of posterior margin; anteromedian campaniform sensilla present. Metanotum polygonally reticulate (Fig. 8); median pair of setae far behind anterior margin; campaniform sensilla present. Ferna entire, undivided; basantra weakly chitinised; meso- and metasterna without spinula (Fig. 5). Fore wing with 34 costal setae (Fig. 9); upper vein with 18 setae, lower vein with 17 setae; clavus with 5 + 1 setae. Abdominal tergite I completely polygonally reticulate; II–VII completely polygonally reticulate except along posterior margin; VIII reticulate at anterior margin only; campaniform sensilla on abdominal tergites little ahead of posterior margin; tergite VIII with complete, fine comb of microtrichia at posterior margin (Fig. 6); tergite IX smooth, with 2 pairs of campaniform sensilla; median setae long and extending beyond apex of X; tergite X elongate, with margins almost parallel, with elongate reticulation, with a complete ventral longitudinal split. Abdominal sternite II with 2 pairs of posteromarginal setae, III–VII with 3 pairs; median setae (S 1) on VIII little ahead of posterior margin; sternites and laterotergites without discal setae. Measurements (holotype female in microns). Body length 2210. Head, length 209; width across eyes 158; width across just behind eyes 134; width across cheeks 161. Ocellar setae II 23–25; ocellar setae III length 38–40; postocular setae I length 44–45; poII 34–37; poIII 28–31. Pronotum, length 171; width 215; outer posteroangular setae length 79–85; inner posteroangular setae length 48–50; median posteromarginal setae length 50–51; submedian posteromarginal setae length 32–35. Metanotum median setae length 45–49; submedian metanotal setae length 43–47. Forewing length 1370–1380. Antenna length 405–423; antennal segments L(W): I 37 –38(36–37); II 50 –51(30–32); III 77 –78(24–26); IV 64 –67(21–23); V 60 (19); VI 83 (23); VII 15 (9); 27 (7). Male. Unknown. Material studied. 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.
