Can somebody help me to differentiate the two species of Pseudomeges.
I have a pair from Thailand and Laos.

Thanks

Dan

Coming to this post, both species are present in the gallery here.

Pseudomeges varioti can be recognised for its small inferior eye-lobes (large in marmoratus), the squared scutellum (elongate in marmoratus) and the larger size (up to 5-6 cm in marmoratus, over 7 cm in varioti).

The first character is well observable in the specimens of the gallery. The scutellum well visible in this Stebbing's drawing:


Meges marmoratus Westwood from India, Southern Shan States, in Stebbing, 1914, Fig. 248

Yes, I understand that Pseudomeges marmoratus (Westwood, 1848) is the Himalayan species and Pseudomeges varioti Le Moult, 1946 is from Yunnan (China), Laos, and probably Thailand.

I have never seen a P. marmoraus to compare, but this one seems to be good one

To complete : Breuning (Laos fauna, 1970) thought that P. varioti is a morpha of P. marmoratus

From this post, I would presume that specimens from Thailand are not P. marmoratus

Did you read this post?
I have no more information, and I haven't received Xaurus' paper.
