Males are characterized by short and strong hind legs with dense pubescence on the inner side of femora (better seen in the right specimen photographed under some angle from behind).
Females with simple hind legs.
Elytra are shiny in both sexes.

Yes. The determination of these species is nice, but exchanges too.
Thanks to everybody

Thanks to all!
A difficult genus, but a great example of collective work.

Ok, c'est astrusa: la description ne laisse aucune doute: "durch die eigenartige Bildung der Hinterbeine beim #9794; eine sehr ausgezeichnete Art" (= une espèce très distinguée pour la conformation unique des pattes postérieures du #9794;).

Xavier... je ne crois pas d'avoir cet article...

Try to check the legs and overall appearance of the body.
Xavier Posted - 14/11/2012 : 16:04:50
Thanks a lot.
I tried to translate a part of the description (hard for me, German language), and with "the more granular base of the elytra" it seems working.
Could you have a look on it, Francesco ?
horshehden Posted - 13/11/2012 : 22:50:07
In most cases, you can find there Anoploderomorpha abstrusa Holzschuh, 1989.

I add one more picture of a male (Hua Phan, nord Laos).
Xavier Posted - 13/11/2012 : 21:51:52
That's true, and threre is not bluish color on my specimens. I think also that it's another species.
Black with last antenomeres white or greyish, it could be A. dissimilis?...
but I will check Holzschuh descriptions from this area.
Francesco Posted - 13/11/2012 : 21:26:06
I have got a male like that, which Xavier has sent me from Laos.
Nonetheless, the description provided by Gressitt (1951) mentioned a "body tinged with bluish" while my specimen is completely opaque.
Moreover, he did not mention this particular femoral pubescence.
Are they really the same species?
Vitali Posted - 13/11/2012 : 20:51:12
Thank you, Xavier. You might be right.
I’ll accept this identification until I have some differential diagnosis. Extremely dense punctuation with very thin intervals between punctures in pronotum is somewhat confusing in my specimens. The punctuation looks like honeycomb. Besides, the pronotum seems completely matt.
My photo is not very good, but this feature is shown correctly. Maybe the difference is because of sexual dimorphism. There are two males in my photo, while yours seems to be a female. A female in my collection has also a bit shinier pronotum.
Xavier Posted - 13/11/2012 : 06:41:43
Here, the same species.
