THAILANDE. Lampang. Taille 49 mm femelle

Je pensais que j'avais à faire a
Aegosoma ornaticolle White, 1853.
Quelqu'un pourrait me le confirmer ?

Bonjour Gérard, je reviens sur ce post ancien qui semble sans réponse.
3 espèces d'Aegosoma sont connus de Thaïlande (cuneicornis, kusamai et katsurai).
Suivant le classement de DO et Drumont (ci-joint), on peut exclure cuneicornis et katsurai dont la longueur des antennes est plus courte (dépassant a peine la moitié des élytres chez la femelle dans mes exemplaires). Quant à kusamai il n'a rien de comparable !.

Pour moi, ce spécimen devrait être un A.sinicum legrandi (qui n'est pas répertorié à ma connaissance de Thaïlande.. mais il faut bien un début à tout !

Merci beaucoup, je vais pouvoir faire l'étiquette.
Selon Titan c'est:
Aegosoma hainanense legrandi Komiya & Drumont, 2012
C'est correct ?

Je préfère le classement Komiya/Drumont,2012 : A. sinicum legrandi

Sinicum hainanensis is a true species (Gahan,1900)

Well, as you can see in the link provided by you above, A. hainanense is a separate species (see Danilevsky, 2011). [Note also that both taxa, "sinica" and "hainanense" live together at least in Hainan, and probably also in Guangxi, Vietnam, etc].

Since "A. sinica legrandi" was compared to A. sinica hainanense and since it is much closer to "hainanense" than "sinica" and since it probably replaces A. hainanense in south Vietnam, Thailand and Malaysia I prefer to keep it as subspecies of A. hainanense.

Anyway, the photo above does not look as "legrandi" I know from Borneo and Cameron Highlands.
