Tyagi, Kaomud, Pal, Shash, Sarma, Madhurima & Kumar, Vikas, 2025, Identification key to the species of genus Thrips (Thysanoptera, Thripidae) from India with three new species and one new record, Zootaxa 5566 (2), pp. 273-302 : 297

Thrips roseae sp. nov.

( Figs 215–221 )

Female macroptera. Body uniformly brown including legs, fore tibiae pale towards apex, all tarsi yellow ( Fig. 215 ); antennal segments I–II brown, III–IV and basal ¼ of V yellow, proximal ¾ of V and VI–VIII brown ( Fig. 216 ); forewing uniformly brown with light shade towards basal end ( Fig. 221 ). Head little broader than long; eyes without pigmented facets; ocellar setae III placed on the outer side of the tangent between fore and hind ocelli; six pairs of postocular setae, poI, and poIV distinctly longer than others, poIV longer than poI ( Fig. 219 ). Antennae 8-segmented, segment III and IV each with a forked sense cone. Pronotum broader than long; surface with transverse striations; with 2 pairs of well-developed posteroangular setae. Mesonotum with widely spaced transverse striations; antero-median campaniform sensilla present; median pair of setae ahead of posterior margin. Metanotum with longitudinal striations, few transverse lines annntomedially; median pair of setae slightly close to the anterior margin; the distance between the median pair less than the median and submedian setae; campaniform sensilla absent ( Fig. 217 ). Forewing first vein 7 basal and 3 discal setae; second vein with 14 setae, clavus with 5 veinal and one discal seta ( Fig. 221 ). Abdominal tergite II with 4 lateromarginal setae; abdominal tergite VIII with posteromarginal comb complete ( Fig. 220 ). Abdominal sternites without discal setae ( Fig. 218 ); sternite VII with S1 setae away from the posterior margin ( Fig. 218 ).

Measurements. (Holotype female in microns). Body length 1589. Head length (width across cheeks) 133 (168); compound eye dorsal length (width) 77 (47); pronotum median length (width) 142 (208). Forewing length 715. Antenna segments I–VIII length (width): 28 (28), 65 (27), 45 (21), 42 (22), 33 (18), 48 (19), 6 (7) and 11 (4).

Male unknown.

Material studied. Holotype female, INDIA, Himachal Pradesh, Solan (31.39 N, 77.11E, 1761 m), on flowers of rose ( Rosa indica ), 7.v.2000, Vikas, in NZC, ZSI, (Reg. No. 15596/H17 ) . Paratypes: 1 female with same data as holotype (Reg. No. 15597/H17 ) .

Etymology: The species is named after the host plant.

Comments: Thrips rosea sp. nov. is similar to Thrips himalayanus (Pelikan) but it can be differentiated by the presence of transverse striations on pronotal surface, forewings weakly shaded at base, antennal segments IV and basal ¼ of V yellow. In contrast, the pronotal surface smooth, forewing completely shaded, antennae dark except segment III in T. himalayanus . This new species is very similar to T. shiranesanus Masumoto & Okajima (2013) and can be differentiated by the presence of 8 segmented antennae, metanotum without campaniform sensilla, abdominal sternite VII with 3 pairs of setae and tergites III to VII without small scallops along posterior margin. In contrast, antennae 7-segmented, metanotum with campaniform sensilla, abdominal sternite VII with 2 pairs of setae on one side and 3 pairs on other side, tergites III to VII with small scallops along posterior margin in T. shiranesanus .
