Jamides pura pura.

[Psyche]

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.

Males
P. Malaysia.

Federick shot a female long ago in which all the submarginal spots were strongly lunulate.



Jamides celeno.
Male UpF with a dark border usually increasing at the apex.
UnF with the submarginal spot 2 more or less in line with the rest.

Female UpH with veins between the submarginal spots strongly darken.
UnF submarginal spots mostly with straight margins.

HW black spot with the silvery side bars usually short or absent.

This observation have the male UpF without the dark border.

This female from the same area have the FW submarginal spots mostly broadly lunulate, suggesting female pura.

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/gallery?taxon_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.

J. celeno typically have the HW striae more uniform in size eg.
All with UpF confirmation.

https://www.inaturalist.org/observations/207131702
https://www.inaturalist.org/observations/208672306

J. pura typically have the UnF outer striaes much enhanced, but this can also be seen in celeno.

28688
The striae are best compared in the HW cell & between vein 4 & 6.

In J celeno there is a tendency to more uniformity of the striae or the postdiscal striae are slightly thicker than the cellend striae & twice thicker than the midcell striae.
https://www.gbif.org/occurrence/1415639758
https://www.gbif.org/occurrence/1415639674

In [I]J. pura[/I ]the postdiscal striae are about as thick as the submarginal striae but about twice as thick as the midcell striae.

PS. Note several ID features are no longer consistent as to be absolute.

1. Both J. pura & zebra tend to have longer sidebars on the tornal black spot, but are not consistent.

2. The dislocation of the HW white striae across vein 6 thought to be seen only for J. zebra also occur in both pura & celeno.
eg.
Male J. celeno (Ranong) shows striae dislocated across vein 6.

A recent observation of Jamides pura pura male is noted here.
https://www.inaturalist.org/observations/269784827

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.

The form of the male J. pura in P. Malaysia is quite standard, the FW margin is marked by a thin black line.
There is no form with a series of black dots on the FW margin.

Jamides celeno aelianus.
Males tend to have more rounded FWs.
The UpF is marked by a dark border which increases upwards.
Even in space 2, the border is noticeably thicker.

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.
