“Let’s look at some chironomids!” Many of Dr. Leonard “Len” C. Ferrington Jr.’s students heard this phrase as he walked into the lab with an excited smile on his face. Len’s enthusiasm for chironomid research whether it be time at the microscope or out in the field was infectious. Whenever a student came to his office describing a new or unique observation or an unknown midge, he would always drop what he was doing to check it out and provide his input. Once he saw these discoveries, he would give you an enthusiastic, but knowing smile and then often describe the localities where he had also made a similar observation or found the same midge. Usually, any interaction with Len would branch out into an extended discussion of some ecological or taxonomic topic and ideas for future research. He always had new ideas to contribute, and certainly had no plans to retire (“Why would I want to do that?!” was a common response when asked). Sadly, Len passed away unexpectedly, on September 11, 2021, while bicycling on the Root River Trail, near Lanesboro, Minnesota.

The name Dicrotendipes sinicus was originally proposed in 2018, but the requirements of the International Code of Zoological Nomenclature were not fulfilled to make the name available. We here re-propose the name with full Code compliance and redescribe and illustrate all life stages of the species to make the name available.

In their comprehensive analysis Cranston et al. (2012) quite unexpectedly recovered a monophyletic Orthocladiinae, except that Propsilocerus Kieffer, 1923, was recovered as a representative of Prodiamesinae. In this short communication I show that Propsilocerus shares morphological synapomorphies with other Prodiamesinae – namely (i) an indirect tracheal connection of the pupal thoracic horn to the adult spiracle and (ii) a parallel-sided rami of female gonapophysis IX.

Male adult of Pseudorthocladius immezensis sp. n is diagnosed and described based on material collected in the high alpine cirque of the Macun area (Immez Lake basin, alt. 2616 m a.s.l.). A combination of morphological characters found in the male adult has allowed us to consider this new species as a local biogeographical representative of the eastern part of the Swiss Alps: coronal suture with lateral extension, low antennal ratio (AR 0.30); distal half of wing hairy; anal point broadly triangular with a characteristic enlarged base; inner apical margin of gonocoxite truncate; superior volsella large lobe-like; inferior volsella double, dorsal lobe nose-like and distinctly bent apically; virga present, with 4 spines; crista dorsalis absent. A differential diagnosis is given, in which some distinguishing morphological characters are summarised. Comments on the ecology and geographical distribution of the new species are also provided.
根据在Macun地区(Immez Lake basin, alt. 2616 m a.s.l.)高高山圈收集的资料，对immezensis Pseudorthocladius sp. n的雄性成虫进行了诊断和描述。在雄性成虫身上发现的形态特征组合使我们认为这个新种是瑞士阿尔卑斯山东部的当地生物地理代表:冠状缝合与侧伸，低触角比(AR 0.30);翅有毛的远端一半;肛尖宽三角形具特征性的扩大基部;gonocoite的内顶端边缘截形;上叶柄大裂片状;下伏匙重瓣，鼻状的背裂片和明显顶部弯曲;处女座存在，具4刺;无背嵴。鉴别诊断给出，其中一些区别的形态学特征是总结。文中还对新种的生态和地理分布作了评述。

There is much left to learn about the diversity of Chironomidae in Brazil. To help to resolve this problem, a preliminary study of the Chironomidae present in a stream located in center of Brazil was proposed. The aim of this research was to provide a first record of the Chironomidae assemblage at Sarandi stream, in the Brazilian Cerrado. Samples were taken using a handheld D-net from the stream in October 2009. The samples were transported to the laboratory where the material was processed and the Chironomidae specimens were slide mounted, counted and identified to genera. Ninety individuals belonging to 15 genera were found, Chironomini was the richest tribe, with seven genera, while Tanytarsini showed the highest abundance of individuals (55.6%). Overall, Rheotanytarsus (20%), Tanytarsus ortoni-group (16.7%) and Lopescladius (14.4%) were the most abundant genera.
