1920. Padenia obliquifascia Rothschild, J. Fed. Malay States Mus., 8 (3): 111.

Type Locality: Sumatra

Material examined: 01 ♂, Andaman & Nicobar Islands, Betapur, 12.506242°N, 92.800488°E, 04.i.2018, leg. Santosh Singh ; 01 ♂, 01 ♀, Andaman & Nicobar Islands, Baratang, 12.261356°N, 92.800488°E, 08.i.2018, leg. H.S. Datta ; 01 ♂, Andaman & Nicobar Islands, Swarajdweep ,

11.973333N, 92.989805°E, 10.i.2018, leg. H.S. Datta.

Diagnosis: This and the next three species are closely similar due to narrower bands on the forewing, of which, the antemedial band is smoothly curved (whereas in P.transversa ,forewing bands are broader and the antemedial band is indented at middle). Padenia obliquifascia is distinct from its other closely similar species i.e., P. acutifascia and P. duplicana by the postmedial band of forewing being less sigmoid. In the male genitalia, P. obliquifascia is distinct from all its other Indian congeners by the bifid costal process. In female genitalia, neck of corpus bursa is broader than in other congeners, densely scobinated, spines covered about 1/3 of corpus bursae.

Distribution in India: North Andaman (Present study). Elsewhere: W. Sumatra ( Rothschild, 1920), Java, Borneo ( Holloway, 2001), Thailand (Černý & Pinratana, 2009); Malaysia (Bucsek, 2012).

Type Locality: Vietnam (Hong Suphi)

Material examined: 01 ♀, Arunachal Pradesh, Ziro ,

27.541993°N, 93.824248°E, 29.viii.2005, leg. Navneet Singh; 01 ♀, Meghalaya, Nehu , 25.616005°N,

19.iv.2017, leg. H.S. Datta.

Diagnosis: Padenia acutifascia is closely similar to P. duplicana but is distinct due to fuscous hindwing. In male genitalia, the costal process of valva is asymmetrically trifurcated: dorsal one slender, rod shaped and the basal ventral process bifid to form crab claw like structure. In female genitalia, ductus bursae more convoluted and broader, spines covered about 1/2 section of corpus bursae.

Distribution in India: Arunachal Pradesh, Mizoram, Meghalaya (Present Study). Elsewhere: China (Fang, 2000); Vietnam, Thailand (Černý & Pinratana, 2009); Cambodia (Bae et al., 2016).
