Flacopimpla barathrica sp. n. and Zatypota flamma sp. n., belonging to the Polysphincta genus-group, are described, the former from Fennoscandia and the latter from Hungary. Like other species of this group for which the natural history is known, the new species are koinobiont ectoparasitoids of spiders. They have been reared from the theridiid spiders Thymoites bellissimus (L. Koch) and Parasteatoda sp. Archer respectively. The host records support the hypothesis of Flacopimpla being parasitoids of the spider family Theridiidae. The results also indicate that F. barathrica sp. n. has a very narrow host range consisting of a single species in Fennoscandia. The genus Flacopimpla was previously only known from the New World, and F. barathrica sp. n. is thus the first species of its genus in the Palaearctic. It is also the first troglophilic species of the Polysphincta genus-group. Zatypota albicoxa (Walker) is reported as new to Hungary.
记述了属于多刺瘤姬蜂属类群的巴拉弗拉科瘤姬蜂新种Flacopimpla barathrica sp. n.和火焰扎蒂波塔姬蜂新种Zatypota flamma sp. n.，前者采自芬兰斯堪的纳维亚地区，后者采自匈牙利。与该类群已知自然史的其他物种一样，这两个新物种均为蜘蛛的类寄生体外寄生蜂。它们分别从球腹蛛科蜘蛛美丽胸腺蛛（L. Koch）和拟壁钱属蜘蛛Archer Parasteatoda sp.中育出。寄主记录支持了弗拉科瘤姬蜂属为球腹蛛科寄生蜂的假说。结果还表明，巴拉弗拉科瘤姬蜂新种的寄主范围非常狭窄，在芬兰斯堪的纳维亚地区仅由单一物种构成。弗拉科瘤姬蜂属此前仅在新世界有记录，因此巴拉弗拉科瘤姬蜂新种是该属在古北区的首个物种。它也是多刺瘤姬蜂属类群的首个喜洞物种。白胫扎蒂波塔姬蜂（Walker）被报道为匈牙利新记录种。
