Chironomid Exchange Forum

Dear Bruno,

In order to narrow down the range of references that may have to be consulted: Do I gather correctly that the source for your material is the Torrente Molgora, a (?fast-)running water East of Milano?

Best,

Martin Spies

The species has a characteristic anal point a short median volsella and a superior volsella with a large digitus, can somebody help me in identification ?

Dear Bruno,

In my opinion you are right that the name Chironomus nuditarsis is nomenclaturally available from the Keyl (1961) work you refer to. The material had been generated by Strenzke, who apparently never got around to describing the species morphologically. However, in

Klötzli, A. M. (1974) Revision der Gattung Chironomus Meig. V. Chironomus nuditarsis Keyl. Morphologische Beschreibung und Vergleich mit ähnlichen Arten. Archiv Hydrobiol. 74(1): 68-81. [publd "August 1974"; in German, with English abstract]

the author reported on page 69 that Keyl had 'courteously made available for our morphological work the nuditarsis material collected by Strenzke'.

Thus, for morphology I would (first) consult Klötzli's work, even if some morphological data may be found in earlier publications. The publication sequence of morphological treatments of the species is nomenclaturally irrelevant, as the species name is available from Keyl (1961).

For all such cases involving names in Chironomus, please recall - among possible others - the following two highly useful sources of information.

Lindeberg, B., Wiederholm, T. (1979) Notes on the taxonomy of European species of Chironomus (Diptera: Chironomidae). In: Sæther, O. A. (ed.): Recent developments in chironomid studies (Diptera: Chironomidae). Ent. scand. Suppl. 10: 99-116.

Dr. Jon Martin's highly helpful webpages, e.g. https://www.chironomidae.net/Martin/JMRes.html, in the present case especially https://www.chironomidae.net/Martin/Chironfiles/Names.htm

Best regards,

Warm regards,

On behalf of the Organization Committee,

At present I have received no reply; my opinion is that
Keyl, H.-G. 1961 Die cytologische Diagnostik der Chironomiden. III. Diagnose von Chironomus parathummi n.sp. und Ergänzungen zur Bestimmungstabelle Arch. Hydrobiol. 58: 1-6.
is the correct citation, even if only cytogenetic characters are given in this paper and C. nuditarsis is not cited as a n. sp. but with Str. as author;
the first adult description that I have found, emphasizing the different BR value between plumosus and nuditarsis is in
Rosin, S., Fischer, J. 1965 Geschlechtsgekoppelte Inversionen bei Chironomus nuditarsis Str. Arch. Julius-Klaus-Stift. VererbForsch. 40: 26-35.
so it is not clear to me how Keyl, 1961 used the name nuditarsis Str.; it seems that Strenzke had just described the adult before 1961, but I have not found where

Chironomus nuditarsis Keyl, 1961 is the correct denomination ?
The original description is in Arch. Hydrobiol, 58, 1961 ?
where only cytological characters are given and Str. is considered the author  ?
Where one can find the first description of the adult male ?

Dear chiro workers

We are working o the read list of Slovakian chironomids and we are short of a picture of Acamptocladius reissi. Does anyone have a good quality photograph of the larva, larval head or imago of A. reissi and wouldnt mind sharing it?

Thank you,
Laci

† Masaru Yamamoto

Today I received the very sad news that our esteemed Japanese colleague, Dr Masaru Yamamoto, has passed away after a long bout with heart disease.

His many excellently illustrated contributions to the knowledge of Chironomidae in Japan deserve a special place in the collective memory of our research community.
