Forum Entomologi Italiani

5th version of the key :
An additional criterion (Ratio : POL/OOL) was added into the couplet 5, to differentiate berberidis & nigripes .
Hence this new version
========
4th version of the key :
Having found on the site ECatSym the Forewings's photos of ciliaris I added an extract of a photo and modified the couplet 3.
Of where this new version
========
3rd version of the Key :
Sometimes the color of the apex of Tibiae 3 can bring a confusion between the ♂ of ciliaris and the ♂ of rustica & ustulata, where from this new version.
===========
2nd version of the Key :
The Wings's dimensional characteristics of some species are not still constant, where from this new version. ===================================================

-------
atrata = rustica
coerulescens = gracilicornis
clavicornis = fuscipes : Forewing a little infuscate
---
The genus Arge is a Argidae
Determination of this sub-family, see : viewtopic.php?f=370&t=21255
The Arge are only ones Argidae having a small apical cell (¢) opened beyond of 2R1
---
Remark about the key :
The distinctive characters of species, of which the name is underlined, are represented (drawing or photos) more below.

If the wings of Arge are closed

Only will be identifed specifically with certainty: ciliaris, thoracica ♀, rustica & ustulata can be confused between them

Photos :
I thank Maurizio Gigli & Marcello Romano for the authorization which they gave me to use their photos to illustrate some species.

Thank you for all your identification keys, Jean-Pierre. I think we could put all them in a different subforum specific for identification keys.

Could you kindly add an image of a forewing with the names of all cells?

Saluti,
Thanks for your message.

A : Yes !
B : Normally the names of all the veins and cells necessary to use the key, should have been written on the drawing of metallica, but I made a mistake (I used a drawing where names are not all written !).
I shall replace this drawing when the forum will allow me (...).

Ciao.
D & JP Balmer

If you want, you can put it in a new message and I'll move it in the first one.

Saluti:
I thank you, but I cannot make it quickly because I have to redo this image and it is a few complicated :
- Replace the drawing in my table of origin.
And
- Take a screenshot.
And
- Reduce it so that it adapts in dimension of a screen of computer l
I am going to try to redo it tomorrow.

Ciao.
D & JP Balmer

COMPLEMENT added
New synonym.
