Jamides zebra lakatti (Corbet)

Superficially the undersides ressemble that of J. celeno but on the uppersides, the FW has a much more intense blue towards the apex and periphery of the wing. The black FW margin is a thread but can be a confusing factor as the cilia are also black, giving a broader impression of the black area. Decidedly a forest insect compared to the much more widespread J. celeno. A possible ID key in the field would be the rather scalloped FW postdical band's outer margin (Thanks Dr Seow). In J. celeno, this is almost always a straight line. (see comparisons on the pix below)

  1. For J. zebra, beside the slightly deeper chalky blue upperside and the slightly broader FW black border which increases at the apex (Corbet 1940). The important point to separate it from J. celeno is the UnHW white discal stripes in spaces 6 and 7 moved out of line with those in spaces 4 and 5 (Riley & Corbet, 1938). The different of the male clasper of the two species confirm the differences.

  2. For J. zebra, based on external morphology, beside the slight deeper chalky blue upperside and the slightly broader border which increases at the apex on UpFW which different from J. celeno (Corbet, 1940). Riley and Corbet (1938) pointed out the UnHW white discal stripes in spaces 6 & 7 moved out of line with those in spaces 4 & 5.
