Request for ID

[Silverstreak]

Dr. Seow ,

May I have your opinion on my ID process and if the identification is correct ?

Basing on the keys of A Revision of the Genus Parnara MOORE (Lepidoptera, Hesperiidae),with Special Reference to the Asian Specie by Chiba and Eliot

My ID process are as follow:

My read of the specimen basing on keys by Chiba and Eliot.


1.Hindwing with spots in spaces 2-5 usually all present and nearly in a straight line (spot in space 4 lightly shifted in).

2. Underside hindwing with spot in space 6 nearly always present.

This is most probably a Parnara apostata

.

The following 3 Parnara species were rule out :


1. Parnara guttata and Parnara ganga do not have spot 6 on UNH


2. Parnara bada was rule out by the following key : UNH spots in spaces 2-5 small and irregular and may be absent, the specimen has clean and distinct spots 2-5. ( Note spots 6 maybe present for P bada)

This should be Parnara bada female.

The revision is written by Chiba with consultation with Eliot & Eliot himself does not use this key in C&P4.

I presume this is taken in Singapore.(Have seen similae examples from Singapore)

There is a definitve image of P. apostata .The upperside is almost black; spots often crescentic; HW spot 6 present.

Horace has a specimen which is dark with 3 small HW spots .This have sharper FWs. I thought it was apostata but has to be P. bada.
