Jamides pura pura is extant in Singapore but field shot identification is extremely difficult.
Jamides pura. Male FW margin straighter than in celeno.
Male UpF with the black border a thread or sometimes a series of small marginal spots.
UnF submarginal spot 2 more chevron with curved sides & more distinct dislocation of the white striae.
Female UpH with the veins between the submarginal spots largely not darken.
UnF submarginal spots all lunulate with curved margins.
Both sexes often have longer silvery side bars on the black spot ,but variable.
New material available prompt a review of this difficult species.
There is a large series of set specimens taken from the Fleming collection.
The specimens were taken from Ampang Reserve (14) The Gap, Raub(1) & Fraser's Hill(1), east of K.L.
Noteworthy the male upperside is very clean with just a thin dark FW margin.
The underside is very consistent in appearance.
The side bars on the tornal black spot can also be absent. https://www.gbif.org/occurrence/gall...on_key=1928895
Even with this new material we are hardly any closer to separating pura & celeno based on the undersides.
At best a suggestion to the likely species is the norm.
While the separationof J. celeno & pura based on the underside seem almost impossible, the ID of the males from the upperside is farly straight forward.
The above observation shows a tear exposing a bit of FW space 2.
This shows no dark border, only a faint dark line at the margin.
In fieldshot identification one always defers to the most common species if identical in appearance.
In Singapore where J. celeno is the overwhelmingly common species J. celeno is the usual ID unless someone can indicate some features which show otherwise.
As an analogy, if someone sees a bigfoot creature, in this time & age it is probably a man in a gorilla suit and not IDed as a bigfoot first.
An eagerness to suggest a rare species often receive a dubious confirmation making the research ID doubtful.
