Apresentamos os primeiros registros dos anelídeos intersticiais das Açores com base nos resultados do workshop "Meiozores2019: Explorando a meiofauna marinha dos Açores - da descoberta à publicação científica". Um total de 12 espécies pertencentes às famílias Diurodrilidae, Microphthalmidae, Nerillidae, Protodrilidae e Saccocirridae foram registadas a partir de observações em microscópio óptico. Também discutimos brevemente a diversidade de outros grupos mesopsâmmicos, embora sua diversidade não seja relatada em detalhes. Apesar da maioria das espécies referidas aqui pertencerem a linhagens amplamente difundidas e apenas uma delas ser inequivocamente nova para a ciência, embora nossa discussão seja limitada devido à falta de dados moleculares e exames morfológicos detalhados (microscopia eletrônica de varredura e confocal a laser). A comparação de nossos resultados com relatórios publicados das respectivas famílias de outros arquipélagos oceânicos ao redor do mundo sugere que os níveis relatados de endemismo de anelídeos intersticiais nas ilhas são fortemente influenciados pela quantidade e escopo da pesquisa realizada em cada arquipélago. Assim, mais informações são necessárias para chegar a qualquer conclusão biologicamente significativa sobre os padrões de diversidade de anelídeos intersticiais em ilhas oceânicas.

A total of 12 species belonging to the families Diurodrilidae, Microphthalmidae, Nerillidae, Protodrilidae, and Saccocirridae were recorded based on light microscopical observations. We briefly discuss the occurrence of other interstitial groups, but their diversity is not reported in detail. Most of the species reported belong to widespread lineages and only one of them is unequivocally new to science although our discussion is limited due to lack of molecular data and detailed (electron and confocal laser scanning microscopy) morphological examinations. The comparison of our findings to published reports from other oceanic archipelagos around the world suggests that levels of island endemism in interstitial annelids are strongly influenced by the amount and scope of research performed in each archipelago. Thus, further information is needed to draw any biologically meaningful conclusion on patterns of diversity of interstitial annelids in oceanic islands.

Abstract
We here provided the first records of interstitial annelids from the Azores based on the results of the workshop "Meiozores2019: Exploring the marine meiofauna of the Azores - from discovery to scientific publication". A total of 12 species belonging to the families Diurodrilidae, Microphthalmidae, Nerillidae, Protodrilidae, and Saccocirridae were recorded based on light microscopical observations. We briefly discuss the occurrence of other interstitial groups, but their diversity is not reported in detail. Most of the species reported belong to widespread lineages and only one of them is unequivocally new to science although our discussion is limited due to lack of molecular data and detailed (electron and confocal laser scanning microscopy) morphological examinations. The comparison of our findings to published reports from other oceanic archipelagos around the world suggests that levels of island endemism in interstitial annelids are strongly influenced by the amount and scope of research performed in each archipelago. Thus, further information is needed to draw any biologically meaningful conclusion on patterns of diversity of interstitial annelids in oceanic islands.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
