260. Mycalesis cf. adamsonii (The Watson's Bushbrown)

Number: 260
Family: Nymphaliidae
Sub-Family: Satyriinae
Species: Mycalesis cf. adamsonii Watson, 1897
Common name(s): The Watson's Bushbrown
Photography location: Ba Vi N.P. (Hanoi)

Mycalesis inopia is one of the 3 vietnamese Mycalesis (with adamsonii and inopia) in which Up of both wings don't exhibit ocelli.

Underwings of Mycalesis inopia appears to be very similar to that of M. adamsonii. Both show a broad white postdiscal band suffused with violet on both wings bearing the same arrangement of ocelli. But according to me (to be confirmed), area from base to postdical band is blackish in inopia wheras it appears somewhat brown ochraceous in adamsonii.

Identification is easy with voucher specimens: M. inopia show black Up (brown in adamsonii) and the male lacks a brand on the UpF (brand overlaid by a hair tuft in space 1b in adamsonii).
