Mosquitoes (Diptera: Culicidae) were collected throughout Finland between 2013 and 2018 to determine species distributions. During the course of molecular identifications of specimens belonging to the Anopheles maculipennis complex, ribosomal internal transcribed spacer 2 sequences and link-reared specimens revealed the presence of Anopheles daciae Linton, Nicolescu & Harbach (n = 37), a new country record, as well as Anopheles messeae Falleroni (n = 19) in the collections. Although the sample size is low, distinctions are apparent in the distributions of these two species, with An. daciae present in south-eastern and central Finland, including the regions of Kanta-Häme, Pirkanmaa, Pohjois-Pohjanmaa, Päijät-Häme and Satakunta, and An. messeae present in the southern and south-eastern regions of Åland (Ahvenanmaa), Etelä-Savo, Kanta-Häme, Kymenlaakso, Päijät-Häme, Satakunta, Uusimaa and Varsinais-Suomi. All reports of An. messeae in Finland prior to 2018 should therefore be recognized as potentially being either An. messeae or An. daciae. Because these species are potential vectors of malarial protozoa, it is important to have full knowledge of their distributions across Europe, particularly in the face of climate warming.
2013年至2018年期间，在芬兰各地采集了蚊子（双翅目：蚊科）以确定其物种分布。在对黄斑按蚊复合体标本进行分子鉴定的过程中，核糖体内部转录间隔区2序列和连锁饲养标本显示，采集物中存在达契亚按蚊Linton、Nicolescu & Harbach（n = 37），这是一个新的国家记录，以及梅塞按蚊Falleroni（n = 19）。尽管样本量较小，但这两个物种的分布差异明显，达契亚按蚊分布于芬兰东南部和中部，包括坎塔海梅、皮尔卡马、北博滕、派亚特海梅和萨塔昆塔等地区，而梅塞按蚊分布于奥兰（阿韦南马）、南萨沃、坎塔海梅、屈米拉克索、派亚特海梅、萨塔昆塔、新地区和滨海萨沃尼亚的南部和东南部地区。因此，2018年之前芬兰所有关于梅塞按蚊的报告都应被视为可能是梅塞按蚊或达契亚按蚊。由于这些物种是疟原虫的潜在传播媒介，全面了解它们在欧洲的分布情况非常重要，尤其是在气候变暖的情况下。
