Winnertzia globifera Mamaev, 1963

Jaschhof, Mathias & Jaschhof, Catrin, 2020, Reevaluation of species richness in Winnertzia (Diptera, Cecidomyiidae, Winnertziinae), with descriptions of 37 new species from Sweden, Peru and Australia, Zootaxa 4829 (1), pp. 1-72 : 19

Winnertzia globifera Mamaev agg.

Our reexamination of 83 Swedish males previously assigned to W. globifera found two morphotypes (named here A and B), which differ in both the outline of the gonostylar apex (either pointed or rounded) and the inclination of the gonostylar claw (either vertical or longitudinal). We noticed variation also in other genitalic structures (notably the aedeagal apodeme), whereas non-genitalic structures gave no clue whether W. globifera comprises more than one species. Our conclusion here is that W. globifera sensu Jaschhof & Jaschhof (2013) is likely to be a complex of two (or more) discrete species, whose taxonomic study in the future should include specimens from a larger geographic area. Also, the status of W. argentata Mamaev and W. subglobifera Mamaev , two junior synonyms of W. globifera , needs to be reconsidered by future revisors. Finally, we realize only now that our Winnertzia aff. xylostei ( Jaschhof & Jaschhof 2013: 84) is closer to W. globifera than to W. xylostei .

Material studied. Specimens listed by Jaschhof & Jaschhof (2013) and those numbered here CEC 3192– CEC 3212 (all in NHRS). Morphotype A is represented by specimens ZFMK-TIS-2527392, ZFMK-TIS-2549538, and ZFMK-TIS-2549539; morphotype B by specimens ZFMK-TIS-2527394, ZFMK-TIS-2527396, ZFMK-TIS- 2527397, and ZFMK-TIS-2549540 (all in NHRS).
