Diagnosis: Forewing length: ♂ 20.5–23 mm. Ptilodon amplius is a member of the ‘ flavistigma species complex’ and externally very similar to P. flavistigma (Moore, 1879), P. saturata (Walker, 1865) and P. spinosa Schintlmeister, 2007.All the four species have brownish forewing, among which P. amplius has most prominent yellowish scales on fuscous-brown ground color, especially on outer half of forewing which differentiates it from P. saturata with less yellowish irroration, and P. flavistigma having very dark, brownish-black ground colour with well-marked reniform stigma. P. amplius can be differentiated from P. spinosa by less contrasting forewing pattern. The pale postmedian fascia and the row of pale dots following it are more distinct in P. amplius than P. saturata. The crenulated blackish fascia originating from the tooth scale to the costa of forewing is also more contrasting in P. amplius than that of P. spinosa and P. flavistigma. The male genitalia in P. amplius possesses small triangular gnathos-like structure in uncus. The valvae are variable and may or may not possess basal spine. The spiny-toothed sclerotizations in the 8 th sternite enclosing a deep furrow are typical to this species.
Remarks: Schintlmeister (2008) reported this species as endemic to NW China, Yunnan and Sichuan. Present record from 1700–2300 m altitudinal zone in Wet Temperate Forest habitats in Dihang-Dibang BR further extends its distribution slightly westward to the Indian territory (Fig. 5). Most of the individuals were sampled in the months of April to July, whereas earlier known activity period of the species was between May to August. This new record brings up the total number of species to five under the genus Ptilodon in India.
