( Figs 2, 3 , 7, 10 )

Miltochrista phaeoxanthia Hampson, 1900: 493 (Type locality: ‘ Assam, Khasis’ [Meghalaya]).

Material examined: India, Meghalaya: 1 Ô, Cherrapunji (25.272857N, 91.7297E, 1430 m), 13.viii.2018, Santosh Singh leg. (13478/H10) , West Bengal: 1 ♀, Sitong , (26.8715N, 88.3616E. 1350 m), 17.ix.2018, Santosh Singh leg. (13474/H10).

Diagnosis: Forewing 13 mm in male and 16mm in female. Externally, B. phaeoxanthia is most closely related to B. apatani sp. nov. The differential diagnosis is discussed above. Furthermore, B. phaeoxanthia is distinct from its other two congeners by the larger size and in male genital capsule ( Fig. 7 ) by the valva distally bifurcated, whereas in B. diehli ( Fig. 8 ) and B. ketiga ( Fig. 9 ) valva is acute apically. In female genitalia, B. phaeoxanthia is distinct from B. ketiga and B. diehli by the ductus bursae with posterior end narrower and the corpus bursae with lateral protrusion of moderate size whereas in B. diehli , the lateral protrusion is smaller and in B. ketiga , the lateral protrusion is larger ( Volynkin et al. 2020: Figs. 34–40).

Distribution: North East India ( Singh et al. 2021), Cambodia (Cardamom, Seima, Koh Kong, Samkos, Pramaoy) ( Bae et al. 2016) Malaysia (Cameron Highlands North) ( Bucsek 2014).
