7. probably Halpe wantona.

This belongs to a pair of species stated in the key to be not separable.
They both have a paler discal area marked by dark interneural spots.
The diffrence is based on an educated guess.

Halpe wantona .
Interneural dark spots narrower with sharp ends, so there is always a postdiscal series of paler spots from FW to HW.

Halpe pelethronix.
Inter neural dark spots broad with rounded ends , so the postdiscla pale spots are much reduced often as a narrow band.

The two species Euploea doubledayi & eyndhovii are very confusing in appearance.


They once were probbaly one species that have differentiated as E. doubledayi on the continent & as E eyndhovii in Sundaland.

When Malaya rejoins the mainland E doubledayi have gradually move south while eyndhovii moves north into Indochinese region.

E. doubledayi is only known mostly in the northern half of P. Malaysia.


Euploea doubledayi.
Lager, may be nearly twice the size of E. eyndhovii.
AS large as E mulciber or larger.
Male upperside appearing blue black.
Female UpF with several white spots.
UnH with the discal spots weak or obscure.

Thai ssp doubledayi.

Euploea eyndhovii.
smaller, much smaller than E. mulciber.
Male Upf dark brown without dark blue sheen.
Female UpF without white spots.
UnF spot in space 1b large.
UnH discal spots often large & clear.

It is doubtful if E. doubledayi have cross the sea into Penang.
All Penang records are probably E. eyndhovii.
Check the size.

Dr Seow,
In reference to E.doubledayi in Penang, would like your opinion on my "possible: sighting of this in Lily Pond, Penang Island in March 2023. It was much larger than most similar crows that I have seen.

I am afraid I cant tell if they are E. doubledayi from the pictures.

The Striped Blue Crow E. mulciber is a very common species, & E. doubledayi is around the same size.
The female doubledayi is also distinctive in having central white spots on the upperside FW.
In contrast the female E. eyndhovii is plain brown on the FW upperside.

E. eyndhovii is found in Penang. The status of E. doubledayi is inknown.
