Subfamily Porricondylinae Kieffer, 1913

There is every indication that this is the most taxonomically diverse of the mycophagous subfamilies of Cecidomyiidae . Its 571 named extant species are classified in 88 genera, whereas the 615 species known of Micromyinae are accomodated in just 41 genera (Gagné & Jaschhof 2021). Each of the three tribes ‒ Dicerurini Mamaev, 1966, Porricondylini Kieffer, 1913, and Asynaptini Rübsaamen & Hedicke, 1926 ‒ is rich in genera and species, with Porricondylini being the largest and most complex tribe (Jaschhof & Jaschhof 2013). The Porricondylinae of Europe previously comprised 53 genera and 272 species, of which 21 genera and 40 species were known from Germany (Jaschhof & Jaschhof 2021b). New additions to the German fauna detailed here amount to 21 genera and 100 species, of which one genus and 24 species are new to science.
