Material examined. ARUNACHAL PRADESH: 1 ♂, India, Arunachal Pradesh , Naharlagun, 28.iv.2016, leg. H. S. Datta (Coll. NZCZSI) ; 1 ♂, India, Arunachal Pradesh , Raga, 05.v.2016, leg. H. S. Datta (Coll. NZCZSI) ; 1 ♂, India, Arunachal Pradesh , Deomali, 05.ix.2005 leg. Navneet Singh (Coll. NZCZSI) .

Diagnosis. Forewing length is 10.5–11.5 mm in males and 11–12 mm in females. Externally, T. nebulosa can be easily separated from other Indian congeners by its bright yellow coloration and presence of longitudinal strokes in the subbasal and subterminal areas of forewing. The male genitalia are similar to those of T. falsinebulosa , sp. nov. but differ by their broader juxta, larger vinculum being rectangular, weaker distal saccular process with its significantly smaller twisted apical lobe, and narrower vesica with smaller medial diverticula. The female genitalia are characterized by the absence of an antevaginal plate, short antrum with smoothly curved margin, and the presence of two signa in corpus bursae.

Distribution. This species is widespread in NE India (Arunachal Pradesh), China (Yunnan), Thailand, Laos, Cambodia and Malaysia (Malay Peninsula and Borneo) ( Hampson 1900; Fang 2000; Holloway 2001; Černý & Pinratana 2009; Bucsek 2012; Bae et al. 2016).
