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.
对来自不同地理区域和栖息地的 malaise 诱捕样本进行的初步研究一致表明，食菌瘿蚊属（Cecidomyiidae）的 Winnertzia 属物种异常丰富，但此前尚无确凿数据证明这一点。瑞典食菌瘿蚊科的分类名录现已显示，在总共发现的 751 个物种中，有 93 个是 Winnertzia 属。2013 年的初步普查仅在瑞典确定了 26 种不同的 Winnertzia 属物种。这种增加有两个因素：纳入了大量新鲜材料进行研究以及采用了更狭义的物种概念。后者是根据 COI 序列（DNA 条形码）数据对雄性形态特征进行重新评估的结果。随着本文描述的 37 个新的 Winnertzia 属物种的加入，该属现在包含 136 个现存物种。在瑞典发现的新 Winnertzia 属物种在此以下列名称描述：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. 和 W. upplandensis sp. nov.。此外，W. panguana sp. nov. 是从新热带地区（秘鲁）描述的首个 Winnertzia 属物种，W. warraensis sp. nov. 是从澳大拉西亚地区（塔斯马尼亚）描述的该属首个成员。Parwinnertzia Felt，1920 syn. nov. 被揭示为 Winnertzia Rondani，1860 的次异名，这意味着 Winnertzia notmani (Felt) comb. nov. 和 Winnertzia italiana (Mamaev Zaitzev) comb. nov. 的重新组合。对 Winnertzia 属内的分类进行了审查并进一步完善，引入了 W. setosa 组，用于指代阳茎突爪明显长且外露，阳茎基节凹陷处有密集大刚毛的物种。Winnertzia feralis Mamaev 从与 W. tridens Panelius 的异名关系中恢复，以及 W. fusca Kieffer 是瑞典新的动物区系记录。过去在瑞典发表的 W. brachypalpa Mamaev 和 W. pravdini Mamaeva Mamaev 的记录基于错误鉴定，这两个物种已从瑞典清单中删除。
