Abstract

Collections of Chironomidae from aquatic habitats on the Azores islands of São Miguel and Flores during August 1997 and on São Miguel, Terceira and Graciosa in September-October 1998, yielded 33 species-level taxa. Representatives of 16 taxa in three subfamilies are new generic / species records for the Azores archipelago: Tanypodinae - Procladius (Holotanypus) choreus (Meigen), Paramerina sp. griechenland, Zavrelimyia sp.; Orthocladiinae - Metriocnemus (Inermipupa) carmencitabertarum Langton et Cobo, Orthocladius (Eudactylocladius) sp., Psectrocladius limbatellus (Holmgren), Psectrocladius sp., Pseudorthocladius sp., Smittia contingens (Walker); Chironominae - Chironomus cingulatus Meigen, Chironomus cf annularius (De Geer), Glyptotendipes barbipes (Staeger), Glyptotendipes pallens (Meigen), Polypedilum nubifer (Skuse), Micropsectra sp. (cf lindrothi Goetghebuer), Paratanytarsus grimmii (Schneider). A revised checklist is provided, incorporating and updating previous records.
