Описание
This manuscript reports on the biological materials of arthropods sampled by the members and collaborators of the University of Azores since the 1990’s on subterranean environments of the Azores. We will highlight the occurrence of endemic species in new localities, therefore increasing their known distribution range. These new records will update the conservation priority of the distinct caves, and records of unidentified taxa can call the attention of prospective taxonomists that might be keen on studying these materials.
A total of 74 species and subspecies are listed plus 16 taxa identified at family or genus level. The 74 identified taxa include 16 endemic species, from which ten are cave adapted species.

| Описание плана выполнения исследований | The examination of cave-dwelling fauna in the Azores employed a range of standardized sampling protocols designed to capture the full spectrum of arthropod biodiversity across different subterranean habitats. Pitfall trapping and direct visual searching were the primary methods, each carefully adapted to the unique environmental conditions of the Azorean lava tubes and volcanic pits. Pitfall traps were strategically placed in diverse microhabitats, taking into account variations in humidity, temperature, and substrate composition. This approach maximized the chances of capturing both ground-dwelling and wandering arthropods. Meanwhile, systematic visual searches allowed researchers to detect species that might otherwise evade passive trapping, such as those that dwell on cave walls, ceilings, or in crevices. By combining active and passive techniques, the study achieved a more comprehensive assessment of arthropod assemblages and minimized sampling biases associated with any single method |

We used Pitfall traps as the most highly effective method for capturing cave-dwelling arthropods, particularly ground beetles of the genus Trechus. Following Amorim (2005): Trap Setup: Small plastic pitfall traps were placed along standardized transects inside lava tubes and volcanic pits. Each transect consisted of 30 pitfall traps spaced along a 500-meter-long transect from the cave entrance inwards. Traps were dug into the ground and placed inside cracks on vertical walls and covered with mesh to protect against rats. To prevent flooding from the region’s high precipitation, plastic dishes were installed above traps as rain cover. As Baiting Strategy several types of baiting were used: i) Pitfall (bait: liver) - live traps baited with fresh cow and/or pig liver that was kept in a special container inside the traps, allowing the collecton of live species; ii) Pitfall (bait: turquin) - live traps baited with TURQUIN (a mixture of 1 litter of dark beer and some preservatives: 5 ml Formaldehyde; 5 ml Glacial Acetic Acid; 10 g Sodium Chloride) that was kept in a special container inside the traps, allowing the collecton of live species; iii) Pitfall (bait: liver + cheese) - live traps baited with fresh cow and/or pig liver and also cheese that was kept in a special container inside the traps, allowing the collecton of live species; iv) Pitfall (bait: turquin + cheese) - killing traps with TURQUIN and cheese that was kept in a special container inside the traps; v) Pitfall (bait: turquin + liver) - killing traps with TURQUIN and liver that was kept in a special container inside the traps. Pitfall traps were left in place for at least seven days and up to a month to ensure adequate specimen collection. Traps were monitored periodically to prevent desiccation or disturbance.
| Охват исследования | Located along the Mid-Atlantic Ridge in the North Atlantic Ocean (approximately 36°55′ to 39°43′ N and 24°33′ to 31°17′ W), the Azores archipelago comprises nine volcanic islands renowned for their extensive network of lava tubes and volcanic pits. Across the archipelago, around 300 such subterranean structures have been identified, with Pico and Terceira hosting the largest concentrations at 118 and 73 caves, respectively. |

| Введение | Azorean lava caves offer critical habitats for a variety of endemic troglobitic species that have evolved distinctive adaptations to life underground, such as depigmentation, reduced or absent eyes, and elongated appendages. These adaptations are a direct response to the stable, lightless environment in which these species dwell. However, because of their isolated distribution and the scarcity of suitable subterranean ecosystems, many cave-dwelling species are highly vulnerable to disturbances such as habitat degradation and fragmentation. To safeguard these specialized organisms and the fragile subterranean environments they inhabit, conservation measures in the Azores include assigning caves to one of four priority categories. Through this system, specific caves—those housing rare or highly sensitive species—are designated for heightened protection, ensuring that management strategies address not only the caves themselves but also the surrounding environments crucial for maintaining cave ecological integrity |
