 ;) I am reviewing the information about morphology of larvae belonging to the genus Diamesa, aiming to prepare a key to larvae,
at least for the West Palaearctic species.
Using the Chironomid Bibliography I see that there are few recent contributions to the matter, while there are many old papers.
I have many questions.
I begin with:
1- in the labrum of D. veletensis is seta SIII simple (Casas & Langton 2001) ? It is bifid in all the related species.
2- is the seta submenti in  Diamesa sp. A (sensu Schmid) in caudal position relative to the ventromental plate as in the dampfi group (Schmid, 1993) ?
In two slides in my collection (Ferrarese & Rossaro 1981) it is not caudal; is Diamesa sp. A (sensu Ferrarese & Rossaro) another species ?
3- is the "halbkreisfoermige Platte" (medial semicircular plate) in D. steinboecki (Wuelker 1959) a valid character to separate D. steinboecki from other species ?
I have seen something similar also in D. tonsa.

Larval samples of Diamesa are well accepted, especially if some association with pupae and/or adults is known.

Dear Professor Rosaro.

I got a new project regarding mountain brooks of Blakan Peninsula. We will start with field work from next month. I hope that I will find a lot of specimens of Diamesa in my samples. Also I have some Diamesa specimens from South Morava river basin. I can send you if you are interested in.

Best regards

Dear Djuradj,
obviously I am interested in samples, even of common species;
beside the examination of new species it is important to be able to evaluate the within species variations;
at present my material is from Italian Alps above all
good Easter


Dear Professor Rossaro,

Ok, great,

First, I will send my samples from South Morava river by mail. Please send me your address of institution where I can send the tubes with specimens.

All the best
