Four new localities for the species Microgasterdeductor Nixon (1968) are recorded from the Nearctic (Canada and the United States) and the Palaearctic (Sweden), expanding significantly the range of the species. Microgasterdeductor seems to be widely distributed in boreal areas of the Holarctic, and it is characterized by unique morphological (tarsal claw structure) and molecular (COI) traits. Preliminary evidence, to be corroborated when more data is available, suggests that the species might have shifted northwards between 1950 and the present day.
记录到微小胃蝇属的尼克松微小胃蝇（Microgaster deductor Nixon，1968）在新北界（加拿大和美国）和古北界（瑞典）出现了四个新分布点，这显著扩大了该物种的分布范围。尼克松微小胃蝇似乎广泛分布于全北区的北方地区，其特征是具有独特的形态学（跗爪结构）和分子（细胞色素氧化酶亚基I，COI）特征。初步证据表明，该物种可能在1950年至现在之间向北迁移，更多数据可得时将进一步证实这一点。
