- Аннотация: Whereas a few macrofaunal nemerteans were described previously from the Azoresislands of Faial and Pico, a survey of marine meiofauna from littoral and shallowsublittoral sediments sampled at São Miguel Island and Santa Maria Island in the Azoresyields this first report of Nemertea for those two islands, with 55 specimens, whereasa search for littoral mesopsammic Nemertea on Pico Island was fruitless. Based onmorphology, specimens were initially thought to comprise twelve morpho-species:four morphs of Cephalothrix Örsted, 1843, accounted for 43 specimens; three morphs ofOtotyphlonemertes Diesing 1863, accounted for five specimens; one specimen of Lineus cf.sanguineus (Rathke, 1799), one of Zygonemertes Montgomery, 1897, and two unknownspecies (one a juvenile) of Eumonostilifera were associated with the sediments; onespecimen of Baseodiscus cf. delineatus (Delle Chiaje, 1825) was retrieved from an incidentalalgal sample. The Cephalothrix morphs collected at São Miguel Island resemble C.rufifrons and C. simula; whereas the morph collected at Santa Maria Island has the habitus“typical” for mesopsammic species of the genus. One of the Ototyphlonemertes morphshas a combination of discrete characters that appears to make it an undescribed speciesendemic to the Azores. All specimens were preserved for genetic analyses, which will bereported as they are completed.
