Could you post your specimen from Vietnam in a different topic ? It should be interesting to see...

Paradryopea birmanica

mmmhm... Paradryopea.
Claws should be opposite and mesotibiae furrowed... maybe Breuning overlooked both characters.
Antennae should be as log a s body... maybe both species were females.
Scape should be convex dorsally... here, it is also ventrally, maybe is due to the positon.
Elytra are larger and stouter... maybe it is due to sexual dimorphism.
P. fruhstorferi shows a complete apical band; here, it shows two lateral pre-apical spots.
P. birmanica shows two lateral spots or a pre-apical band not reaching the suture but also a large basal band (here missing).

Who identified your specimen, Andre?

For your specimen, Andreas, the question is : mesotibiae furrowed or not ?

My specimen, sure a Gyaritini, as simple mesotibiae, without any furrow.

my spm has a small furrow, at the last 3rd of mesotibia, not quite clear too see because of thick hairs. I'll make a picture next days.
Maybe your spm is different from my. Look at your 5. posting (beetles and hind wings) I think there is a small furrow visible at the left mesotibia without fail different from Pteropliini tibia.

The problem is that claws are clearly normal (not opposite).
Accordingly, species with normal claws and furrowed mesotibiae can also belong to Apomecynini, Homonoeini, Hippopsini (= Agapanthiini), Xylorhyzini, Tragocephalini and Onciderini.
I do not see any of that tribes.

This spm we det. as Paradriopea fruhstorferi.
The middle tibia shows a very weak furrow only.

Thank you a lot Andreas!

Xavier's species seems to be another one.
However, claws are not opposite; thus, this genus cannot belong to the Acanthocinini.
According to me, it belongs to Apomecynini, close to Athylia.

ok Francesco my spm differs from Xaviers of course.
I don't believe this is a member of Apomecynini - long legs, 2 small spines at the pronotal disk, last joint of maxillar palpus hatchet-shaped.

mmmhm... according to Xavier, the furrow on the mesotibia is an optical effect.
Thus, we come back to Gyaritini...

Dear all,
- My specimen has no furrow on mesotibias (X 40): it is only the base of clear hairs that we do not see on picture.
- No such deep punctuation on Paradriopea birmanica, and Breuning do not speak about deep punctuation for the "close" species P. fruhstorferi in description.
- last joint of maxillar palps hatchet-shaped seems to be shared by all Gyaritini males

My species, Andre species and Andreas species all belong to the same genus, and are Gyaritini for me.

Yes Xavier, for me this spm belongs to Gyaritini too, of course.
If Breuning didn't mention anything that's no reason it doesn't exist.
We id our spm as P. fruhstorferi acc CH. I wonder I have no picture from the type, maybe is not in ZMB ?

This caracter is also shared by some Exocentrus-species, which - however - might be further still not recognised Gyaritini...
