The data we present consist of an updated checklist of the Azorean Staphylinidae (Insecta, Coleoptera), by compiling new identified records of three recent published studies about Azorean arthropods. In general, the records were obtained from different standardised sampling campaigns and from non-standardised observations. The presented records were collected between July 1999 and September 2020, in five islands of the Azores Archipelago: Flores, Graciosa, Terceira, São Miguel and Santa Maria. The samples include records collected in several habitat types, such as native, mixed and exotic forests, pasturelands and agricultural areas (maize fields, orchards, citrus areas and vineyards). This inventory represents the most updated checklist and knowledge about Staphylinidae in Azores and new information includes one new exotic rove-beetle for the Azores (Thecturota tenuissima Casey, 1893) and seven new islands records.
arthropods, Azorean Archipelago habitats, biodiversity, inventory, Staphylinidae
The Staphylinidae (Coleoptera) is one of the most diverse families of beetles in Azores and elsewhere. Until 2010, Azorean Staphylinidae knowledge was limited in comparison with other Macaronesian archipelagos (e.g.
More recently,
Given the taxonomic complexity of rove-beetles (Coleoptera, Staphylinidae), it is common that many collected individuals are misidentified or remain identified at genus or family level. In this study, we compiled all these records about Staphylinidae from three previous studies (
The study area comprise the Azores Archipelago, which is located in the North Atlantic Ocean (37-40°N, 25-31°W), about 1600 km from Europe and 2200 km from North America. The Archipelago, which has volcanic origin, is formed by nine main islands and some small islets. The islands are divided into three main groups: the western group (Corvo and Flores), the central group (Faial, Pico, Graciosa, São Jorge and Terceira) and the eastern group (São Miguel and Santa Maria). The climate is temperate oceanic, with regular and abundant rainfall, high levels of relative humidity, above 95% on average on native forests and persistent winds, mainly during the winter and autumn seasons. The landscape of the islands was dramatically altered as a consequence of human settlement in the 15th century, where native forests were replaced by exotic tree plantations, agricultural and urban areas (
The records of the study were collected on five islands of the Azores Archipelago, Flores, Graciosa, Terceira, S. Miguel and Sta. Maria. The samples were collected in several habitat types, as native, mixed and exotic forests, pasturelands and agricultural areas, as maize fields, orchards, citrus areas and vineyards.
This updated checklist of Staphylinidae compile new identified records of three recent published studies about Azorean arthropods (
In general, the records were obtained from different standardised sampling campaigns and from non-standardised observations. The presented records were collected between July 1999 and September 2020. The sampling methods included Active Aerial Searching, Beating Protocol, Pitfall and SLAM traps. Additional non-standard records are based on cave, colour and malaise traps and direct observations. Specific sampling protocols are detailed on the original publication of each Project (see
We provide the updated GBIF Event and Occurrence Tables including the new identifications in Suppl. materials
All sorted specimens were identified by a taxonomical expert (MS) using standard methods for the identification of Staphylinidae, that included the extraction of male genitalia when necessary. Specimens were mounted with genitalia also mounted or stored in a small vial and all vouchers are deposited at Entomoteca Dalberto Teixeira Pombo (DTP) at the University of Azores. Taxonomic nomenclature followed
We identified a total of 359 collected Staphylinidae individuals, belonging to 22 species. A total of 18 species are considered introduced (n = 350 individuals) and four native non-endemic (n = 9 individuals).
In this study, we registered a total of eight new records for the islands of Azores (six for Terceira Island and two for São Miguel Island. Four out of the eight records are native non-endemic species. Thecturota tenuissima Casey, 1893 is a new record for the Azores Archipelago (Table
Updated inventory of Staphylinidae species collected in five islands of Azores, from 1999 and 2020. The list includes individuals identified at species-level. Scientific name, colonisation status (CS; int = introduced, nat= native non-endemic) and abundance per island are provided. Bold scientific names constitute new records.

Thecturota tenuissima Casey, 1893 was sampled in a low elevation maize field in the localitty of São Mateus (Terceira Island). This species is native to the Nearctic, occurring in Canada and United States (
This publication increases the knowledge on the Azorean beetles and updates the recently-published checklist of Azorean rove-beetles (
The Azorean rove-beetle fauna is one of the most diverse within the beetle fauna, but relatively poor in terms of endemic and native species (
With such categorisation we hope to create a debate on the colonisation status of Azorean beetle fauna and inspire taxonomic revisions that will improve our knowledge on the biogeographical status of the Azorean species.
