Non-biting midges of the fly family Chironomidae are extremely abundant and diverse in Arctic regions and are essential components of Arctic ecosystems. Modern identification tools based on documented records of Arctic chironomid species are therefore important for ecological research and environmental monitoring in the region. Here, we provide an updated review of the chironomid fauna of the Svalbard archipelago and the island of Jan Mayen, Norway. Our results show that a total of 73 species distributed across 24 genera in four subfamilies are known from these areas. Our review treats 109 taxa, including nomina dubia and misidentifications. It includes morphological identification keys to all known species as well as photographs of most taxa and DNA barcodes of 66 species. Taxonomic remarks are given for selected taxa, including previous misidentifications and erroneous records. Chironomus islandicus, Tvetenia bavarica, Limnophyes schnelli, Metriocnemus brusti and Metriocnemus fuscipes as well as the genera Allocladius, Corynoneura and Bryophaenocladius are reported from Svalbard for the first time, while Procladius (Holotanypus) frigidus, Stictochironomus psilopterus, Chaetocladius incertus, Orthocladius (Orthocladius) mixtus and Smittia longicosta, previously considered as junior synonyms or nomina dubia, are revived as valid species based on examination of type material or literature. Twenty species within eleven genera are introduced with interim names. Metriocnemus similis is regarded as a junior synonym of Metriocnemus ursinus, and Smittia incerta, Smittia flexinervis and Smittia spitzbergensis are regarded as nomina dubia. Valid taxa no longer considered as part of the Svalbard fauna are Parochlus kiefferi, Arctopelopia barbitarsis, Procladius (Holotanypus) crassinervis, Diamesa lindrothi, Diamesa incallida, Diamesa lundstromi, Chironomus hyperboreus, Sergentia coracina, Camptocladius stercorarius, Chaetocladius dissipatus, Chaetocladius dentiforceps, Chaetocladius laminatus, Chaetocladius perennis, Cricotopus (Cricotopus) humeralis, Cricotopus (Cricotopus) polaris, Hydrosmittia ruttneri, Limnophyes edwardsi, Metriocnemus picipes, Metriocnemus tristellus, Orthocladius (Eudactylocladius) gelidus, Orthocladius (Euorthocladius) thienemanni, Orthocladius (Orthocladius) obumbratus, Orthocladius (Orthocladius) rhyacobius, Paralimnophyes, Paraphaenocladius impensus, Psectrocladius (Monopsectrocladius) calcaratus, Psectrocladius (Psectrocladius) psilopterus, Psectrocladius (Psectrocladius) ventricosus, Smittia lasiophthalma, Smittia lasiops and Zalutschia tatrica.

斯瓦尔巴群岛和扬马延省的猫科（双翅目）

蝇科蝇科的无咬mid在北极地区极为丰富和多样，是北极生态系统的重要组成部分。因此，基于记载的北极奇异虫物种记录的现代识别工具对于该地区的生态研究和环境监测至关重要。在这里，我们提供了斯瓦尔巴群岛和挪威扬马延岛的奇龙动物区系的最新评论。我们的结果表明，从这些地区已知共有73个物种分布在四个亚科的24个属中。我们的审查处理了109个分类单元，包括名古屋和错误识别。它包括所有已知物种的形态学识别码，以及大多数分类群的照片和66个物种的DNA条码。给出了某些分类单元的分类注释，摇islandicus，Tvetenia bavarica，Limnophyes schnelli，Metriocnemus brusti和Metriocnemus蝽以及下列属Allocladius，Corynoneura和Bryophaenocladius从斯瓦尔巴报道首次，而Procladius（Holotanypus）frigidus，Stictochironomus psilopterus，Chaetocladius incertus，Orthocladius（Orthocladius）mixtus和Smittia longicosta以前被认为是初级同义词或nomina dubia的动物，根据对材料或文献类型的检查，被恢复为有效物种。介绍了11个属中的20种，并使用了临时名称。短小Metroocnemus similis被认为是ursinus的Metriocnemus的简写，而Scerttia incerta，Smittia flexinervis和Smittia spitzbergensis被认为是nomina dubia。不再被视为斯瓦尔巴群岛动物群一部分的有效分类群包括Parochlus kiefferi，Arctopelopia barbitarsis，Procladius（Holotanypus）crassinervis，Diamesa lindrothi，Diamesa incallida，Diamesa lundstromi，摇蚊hyperboreus，Sergentia鸦鹃鵙属，Camptocladius stercorarius，Chaetocladius dissipatus，Chaetocladius dentiforceps，Chaetocladius laminatus，Chaetocladius多年生，Cricotopus（Cricotopus）humeralis，Cricotopus（Cricotopus）北极星，Hydrosmittia ruttneri，Limnophyes巨鼠，Metriocnemus picipes，Metriocnemus tristellus，Orthocladius（Eudactylocladius）gelidus，Orthocladius（Euorthocladius）thienemanni，Orthocladius（Orthocladius）obumbratus，Orthocladius（Orthocladius）rhyacobius，Paralimnophyes，Paraphaenocladius impensus，Psectrocladius（Monopsectrocladius）calcaratus，Psectrocladius（Psectrocladius）psilopterus，Psectrocladius（Psectrocladius）ventricosus，Smittia lasiophthalma，Smittia lasiops和Zalutschia tatrica。
