Uncertain / Unpublished / Psectrocladius or Nanocladius ...
Last post by Laci Hamerlik - April 15, 2021, 11:47:13 AM
Dear all,

this head capsule was found in a sediment of a man-made reservoir in Slovakia. At first glance we identified it as Psectrocladius but giving it a second look, I see certain similarity with Nanocladius branchicolus... I have never seen the larva of it though. Could someone who is familiar with the species (-type) give me opinion on this?

Thanks!
Keep healthy

Adults / Leg ratios > 1 on all legs
Last post by Martin Spies - April 13, 2021, 09:52:17 AM
Dear colleague,

Tang & Cranston (2019 in Raffles Bulletin of Zoology 67: 684-693) recently established the tribe Chironominae - Xiaomyiini, which currently includes the genera Xiaomyia Sæther & Wang, 1993 and Shangomyia Sæther & Wang, 1993. One of the diagnostic characteristics of adults of both sexes in this tribe is that the leg ratios (length of tarsomere 1 / length of tibia) are substantially greater than 1 on all legs, and especially so on the mid and hind legs.

If you are aware of any chironomid adult other than those in Xiaomyiini that shows similar leg ratios, please let me know by sending e-mail to spies@snsb.de.

Thanks and best wishes,

Martin Spies
