RESUMO
Tentative studies of Malaise trap samples from different geographic regions and habitats indicate unanimously that Winnertzia, a genus of mycophagous gall midges (Cecidomyiidae), is exceptionally speciose, but hard data in proof of that were previously unavailable. A taxonomic inventory of mycophagous cecidomyiids in Sweden has now revealed that, of 751 species found in total, 93 are Winnertzia. A preliminary census in 2013 had identified only 26 different Winnertzia in Sweden. Two factors are responsible for this increment: the inclusion of large amounts of fresh material to study and the application of a narrower species concept. The latter results from the reevaluation of male morphological characters in the light of COI sequence (DNA barcoding) data. With the inclusion of 37 new Winnertzia described here, the genus now contains 136 extant species. New Winnertzia discovered in Sweden are described here under the following names: W. acutistylus sp. nov., W. angustistylus sp. nov., W. arctostylus sp. nov., W. bicolor sp. nov., W. brachytarsus sp. nov., W. dentata sp. nov., W. egregia sp. nov., W. ekdalensis sp. nov., W. fraxinophila sp. nov., W. grytsjoenensis sp. nov., W. hamatula sp. nov., W. hemisphaerica sp. nov., W. imbecilla sp. nov., W. incisa sp. nov., W. inornata sp. nov., W. lapponica sp. nov., W. lobata sp. nov., W. longicoxa sp. nov., W. normalis sp. nov., W. oelandica sp. nov., W. ombergensis sp. nov., W. parvidens sp. nov., W. pilosistylus sp. nov., W. pratensis sp. nov., W. pustulatula sp. nov., W. quercinophila sp. nov., W. rickebasta sp. nov., W. ruliki sp. nov., W. serri sp. nov., W. setosa sp. nov., W. silvestris sp. nov., W. smalandensis sp. nov., W. sundini sp. nov., W. tumidoides sp. nov., and W. upplandensis sp. nov. Additionally, W. panguana sp. nov. is the first Winnertzia described from the Neotropical region (Peru), and W. warraensis sp. nov. is the first member of the genus described from the Australasian region (Tasmania). Parwinnertzia Felt, 1920 syn. nov. is revealed to be a junior synonym of Winnertzia Rondani, 1860, implying the recombinations of Winnertzia notmani (Felt) comb. nov. and Winnertzia italiana (Mamaev Zaitzev) comb. nov. The intrageneric classification of Winnertzia is reviewed and developed further, with the W. setosa group introduced for species whose gonostylar claw is conspicuously long and exposed, and whose gonocoxal emargination is bordered by dense, large setae. Winnertzia feralis Mamaev, revived here from synonymy with W. tridens Panelius, and W. fusca Kieffer are new faunistic records in Sweden. Swedish records published in the past of W. brachypalpa Mamaev and W. pravdini Mamaeva Mamaev rest on misidentifications, and both species are deleted from the Swedish checklist.

Twenty-two new species of Zadbimyia, a new genus of the tribe Asynaptini, are described from Costa Rica, the first new descriptions of Neotropical Porricondylinae (Cecidomyiidae) in modern times. The new species are: Zadbimyia aberrans, Z. anniae, Z. artborkenti, Z. browni, Z. carolinae, Z. costaricensis, Z. dubia, Z. elenae, Z. elviae, Z. holdenae, Z. inornata, Z. lasalturas, Z. marcoi, Z. membranacea, Z. minima, Z. spinapiscis, Z. talamanca, Z. tapanti, Z. viquezi, Z. wendyae, Z. zumbadoi, and Z. zurqui. All species were found during the Zurquí All-Diptera Biodiversity Inventory, in mid-elevation (1600 m) cloud forest in the central highlands of Costa Rica. A maximum of 19 species occurred at a single site. Pseudocamptomyia Parnell, a genus known from one species in northeastern United States and possibly two species in Somalia, was identified as the closest relative of Zadbimyia. Ultraviolet light traps proved to be the most effective device to collect adults of Zadbimyia. As a peculiarity in Porricondylinae, the circumfila of Zadbimyia males are multi-looped and not substantively different from the circumfila known from male Cecidomyiidi (subfamily Cecidomyiinae).
