Hi guys,
thanks for the interesting contributions!
Concerning the Acomoptera-Drepanocercus-Paratinia group, also molecular data suggest their very close relationship, so that they could well be considered as a single genus. I can also confirm the variation in wing characters in this group, but also in other groups (e.g. in Grzegorzekia collaris).
This week I should have some time to check the numbers and taxa included in the table sent by Dalton, at least for the Oriental Region. Brachyradia is missing among the Exechiini, so I will add it. Do you want to include also some approximate numbers of species (mostly undescribed) known to me in the genera not yet recorded from this region? For example, something like Austrosynapha is quite common from Thailand to Borneo, and it would be good to include it to the table, similarly Acomoptera, Grzegorzekia etc. I can put it there with a note like "unpublished" or "undescribed".
Cheers,
Jan
Yes, I know this is not new in any way - just not firmly established so that
we all use the same terminology, but that's the purpose of our project,
right? For now I and many just avoid the problem by using informal terms like
anterior and posterior fork. By the way, Drepanocercus spinistylus was moved
to Acomoptera by Kerr (2011) and these species show a considerable
intraspecific variation in the length and attachment of the "posterior" fork.
