| Most probably a male of Aegosoma ornaticolle White, 1853. |

| As for me, A. ornaticolle has a different pubescence of the pronotum. Can we assume that this is a subspecies of A. fuliginosum? |

Hello Sergei, Aegosoma ornaticolle White gets its name from the particular arrangement of the four light hair spots at the corners of the pronotum (see attached type), which seems to be the case on your specimen despite the rubbing marks).
On the other hand, the habitus of fuligisosum is more slender with a dark grey, satin-like appearance and inconspicuous costae. Aegosoma fuliginosum is described from Laos and China but it remains possible that it will be later from Thailand and I also notice that there are few citations for ornaticolle from Thailand, to be deepened thus...

It is definitely not A. ripaillei which is described from Yunnan and which has particularly short antennae.
Here a paratype of A. ripaillei

Male and female from Western Yunnan (Yingjiang and Yangbi respectively).
The length of the male is 43 mm, the female is 38.5 mm.
The affiliation of the male to A. ripaillei is somewhat doubtful. It is from the same locality but has longer antennae and more prominent ribs on the elytra than males from the type series.
Perhaps it is a so-called evasive specimen or is another taxon, which, in any case, requires further study. Exactly the same specimens are known from northern Thailand.
Unfortunately, I was unable to upload the photo despite several attempts.

Dear Sebastes, the HTLM system meets usually problems to upload images if you use characters in the titles of the images as "," "." "&" "?" "!" accented letters or empty spaces.
It is necessary avoid all these characters using only letters and numbers without odd characters.  |
