New Dicerurini from Europe, mostly Sweden (Diptera: Cecidomyiidae, Porricondylinae) Author Jaschhof, Mathias Author Jaschhof, Catrin text Zootaxa 2019 2019-02-20 4559 2 245 264 journal article 27451 10.11646/zootaxa.4559.2.2 2845efb7-0c6c-4842-a407-a995f2e77002 1175-5326 2626958 175EB654-85D7-4472-BF78-9C62BCBCA228 Tetraneuromyia Mamaev, 1964 This Palearctic genus of previously nine species ( Jaschhof & Jaschhof 2013 , 2015 ) is enlarged here by four new species from Sweden and Slovakia . Three of the new species are true novelties, whereas the fourth results from splitting T. lamellata Spungis, 1987 sensu Jaschhof & Jaschhof (2013) into two discrete species. Furthermore, the male of T. bulbifera Mamaev, 1964 is redescribed based on specimens from Sweden , thereby completing our revision of Tetraneuromyia species begun earlier ( Jaschhof & Jaschhof 2013: 155ff. ). Tetraneuromyia varimezovi from Bulgaria , a species of which we have not seen specimens, seems to resemble T. lenticularis ( Spungis, 1987 ) , if the male genitalic sketch provided by the describing authors ( Mamaev & Dimitrova 1998: fig. A ) is correct. The genus Tetraneuromyia is characterized by the tegmen whose basic structure is a central trunk of inverted T-shape, which extends into long, bent apodemes basolaterally and one or two pairs of processes apically (see, for example, Fig. 23 ). Size, outline and orientation of the tegminal processes have merit for the identification of species ( Jaschhof & Jaschhof 2013 , 2015 , this paper). The only exceptions from this pattern are T. lamellata and T. errata sp. nov. , two similar-looking species, whose tegmina lack processes, but have fringes of small barbs ( Figs 26–28 ).
