If you blow up both images & compare all the spots and markings from the left FW inwards to the body & you will find they are quite matching.

Most likely Problepsis vulgaris.

This and P. delphiaria are most similar.
Others have the Fw discal ocellus rounded & not attached to the lower margin.

P. vulgaris is about 1.5X larger , the FW ocellus more angular ,& its inner margin not convex.

Theretra clotho.


Four species are very similar in appearance at rest.
Look at the FW for the postmedial line.
This line runs from the cFW tip to the lower margin.
Then look for the antemedial line that is parallel to it
This start from the costa downwards.



Theretra alecto.
HW deep pink (hidden)
FW antemedial moderate/weak.
FW postmedial line intact, not punctate (broken into spots)
Abdomen no dorsal lines sometimes weakly.

Theretra clotho.
FW postmedial line entire as in alecto.
FW antemedial line weak/obsolete.
Some dark shading around black discal dot.
HW dark blackish (hidden).
Abdomen no dorsal lines.

Theretra boisduvalii.
FW antemedial line weak/obsolete.
FW postmedial line punctate, ie broken into a series of spots at each vein point.
Abdomen no dorsal lines, sometimes faint

Theretra lucasii.
Smaller, FW deeper ie wider at the lower margin so that it is more triangular with straight outer margin.
HW dark.
FW antemedial line moderate.
FW postmedial line punctate, broken into spots.
Abdomen no dorsal lines.

Theretra rhesus. (Light forms resemble T. alecto but greyer.)
FW with ante & postmedial lines well-developed & heavier. Multiple lines visible
Thorax & abdomen with two parallel dark lines.
HW dark.

Note many mis-IDS on the web.

eg.

1. T. rhesus .Multiple lines, abdomen with 2 parallel lines.
Correction: correct as Theretra alecto .Pinkier brown.Faint lines on abdomen can be present
T. rhesus also not known in India.
https://www.mothsofindia.org/sites/m...0ef33afd-1.jpg
In this image below the red HWs is a positive ID for T. alecto.
https://www.gbif.org/occurrence/4924090007

2. T. boisduvalii . FW wingshape not triangular. outer margin not straight.
https://www.mothsofindia.org/sites/m...e7408887-3.jpg

3. T. lucasii . Triangular FW with straight outer margin; FW postmedial line punctate.

Theretra nessus.
Typically heavily brown in the costal zone with green on the costal edge.
Postmedial zone also dark, the medial zone paler becoming whitish at the apical costa.
Body also with green shading.

TL Seow; Cheers.

[Saffron]

Thank you so much for your invaluable help in identifying the moth species and for sharing the ID keys. Your guidance has been incredibly helpful, and I am deeply grateful for your time and effort in assisting me with my research. I am posting here some more species for your review, some i could not even come to a definite conclusion. So can you please help me out in confirming their identity followed by the definite keys.

18. Amblychia nimia? Same individual.

23. No conclusion.

24. Same individual. So unique in appearence

25. Could not drawn any conclusion. Perhaps from Sterrhinae sub-family (Geometridae)

26. So many similar looking species.

Probably Episteme maculatrix.

There is a lot of confusion as what is E. maculatrix & nipalensis.
Whether the postmedial spots have blackened veins is immaterial.

According to original decription.

Episteme maculatrix .Westwood 1841.
Westwood described Eusemia maculatrix as
https://archive.org/details/cabineto...p?view=theater
He states the hindwing is a rich orange-red, and the abdomen orange banded black.
An image is provided Plate XXXIII, fig 1.(According to Funet website fig 1 is misidentified & is E. nipalensis)
https://archive.org/details/cabineto...p?view=theater


Episteme nipalensisButler 1875
Butler describe Eusemia nipalensis in which he compare to E. maculatrix.
The differences he noted are.
1. Fw with the four central spots larger & more angular.
2. HW bright orange instead of deep red of maculatrix.
3. Abdomen oranger with narrower bands.
(Westwood commented the banding is more in hte female.
https://archive.org/details/annalsma...p?view=theater

Based on the described difference this below should be Episteme nipalensis.
https://www.mothsofindia.org/sites/m...dd01da16-2.jpg

This with the FW spots smaller & less angular , the HW marked deep red should be E. maculatrix.
https://www.butterflycircle.com/atta...1&d=1737046320

In conclusion E. nipalensis have larger angular FW central spots, deep red HW with a smaller black patch.
E. maculatrix have smaller more rounded FW spots & a bright orange HW with a larger black patch.
(maculatrix= spotty look.)

These should be forms of Episteme maculatrix.

TL Seow: Cheers
.PS.
Confusingly another species Chelonomorpha austeni ,1879 Moorei, tL Assam is practically identical to E. nipalensis but there is little mention of this species.

Amblychia pardicelata. Correction: Should be A. hymenaria.

Two similar species in which the wings have a postmedial series of whitish lunulate spots on a diffuse mottled ground.

Amblychia pardicelata.
Smaller species with rounder broader wings.
HW shallowly dentate.
