The Swedish species of fungivorous Cecidomyiidae have been the subject of comprehensive inventory in recent years (2004-2012). Notwithstanding these efforts,which are unparalleled in the remainder of Europe and the World, a follow-up project running over four months (May-August, 2014) revealed the presence in Sweden of an additional 28 species of Lestremiinae, Micromyinae and Porricondylinae. T...

Sirovena Bouček (Chalcidoidea: Pteromalidae, Pireninae) was known only from females of its type species, S. stigma Bouček, 1988. Males and host associations were both unknown. Both sexes of a second species of Sirovena, S. costallifera sp. nov., reared from Ficus microcarpa L. (Moraceae) in Yunnan, China, are described based on morphological characters and mitochondrial COI sequences. The males...

Exploration of the biotype structure of Hessian fly, Mayetiola destructor (Say) (Diptera: Cecidomyiidae), would improve our knowledge regarding variation in virulence phenotypes and difference in genetic background. Microsatellites (simple sequence repeats) and single-nucleotide polymorphisms (SNPs) are highly variable genetic markers that are widely used in population genetic studies. This stu...

The saddle gall midge, Haplodiplosis marginata (von Roser) (Diptera: Cecidomyiidae), is a phytophagous species that develops in saddle-shaped galls on stems of wheat Triticum vulgare, barley Hordeum sativum, rye Secale cereale, and some other species of Poaceae. Only one generation develops per year. Full-grown larvae leave galls and drop onto the soil where they remain up to the springtime of ...

We describe a gall midge Parampelomyia yukawai Elsayed and Tokuda gen. nov. sp. belonging to the subtribe Schizomyiina (Diptera: Cecidomyiidae: Asphondyliini) based on an integrative taxonomic study. This species forms barely-swollen flower bud galls porcelain berry Ampelopsis brevipedunculata var. heterophylla (Vitaceae) in Japan. The new genus is distinguishable from all known schizomyiine ge...
