Diagnosis. Forewing length is 16.0–19.5 mm in males and 21.0–22.5 mm in females. Externally, the species (Figs 5–7) differs from the patternless form of B. biformis (Figs 3, 4) in its larger size and paler forewing ground color; B. perpallida also resembles B. hololeuca and B. flavicollis, but differs from B. hololeuca (Fig. 8) in its pale ochreous patagia, slightly darker forewing ground color and ciliate male antennae (shortly bipectinate in B. hololeuca); from B. flavicollis (Fig. 9) it differs in its slightly darker forewing ground color and ciliate male antennae (shortly bipectinate in B. flavicollis). The male genitalia of B. perpallida (Figs 34, 35) differ from those of B. hololeuca (Fig. 36) and B. flavicollis (Fig. 37) in their smaller juxta, distally broadened valva with a large distal costal process, trigonal medial costal process directed distally, much longer basal saccular process, and different configuration of diverticula of vesica. The female genitalia of B. perpallida (Fig. 49) differ from those of B. biformis (Fig. 48) in significantly narrower ductus bursae, smaller corpus bursae without signa and scobination, and longer appendix bursae.
Remarks. This species was considered by HAMPSON (1900) to be a member of the genus Miltochrista, and the name M. perpallida was introduced as a replacement for the name M. pallida Moore, 1878, which was a junior secondary homonym of Miltochrista pallida (Bremer, 1864). According to the article 59.3 of ICZN (1999), the name M. pallida Moore is permanently invalid as it was replaced before 1961 and the name M. perpallida was in use after its introduction (HAMPSON 1914; STRAND 1922; FANG 1991, 2000; SINGH et al. 2014; ČERNÝ & PINRATANA 2009).
Diacrisia porthesioides was described on the base of female syntypes from Sikkim (ROTHSCHILD 1910). Examination of their genitalia proved their conspecificity with B. perpallida.
Distribution. North East India (Sikkim, north of West Bengal), East Nepal (Solukhumbu Distr.), China (Xizang). The records for Yunnan (FANG 1991, 2000) need confirmation.
