In total, 93 species were recorded, of which 28 are reported for the first time in Slovenia, increasing the known Slovenian Psychodidae to 93 species, and three are newly documented for Croatia. Species richness per locality ranged from single-species occurrences to 12 species, reflecting the diversity of aquatic and riparian habitats. According to IUCN and national assessments, five species are Critically Endangered (CR), eight Endangered (EN), seven Vulnerable (VU), and 19 Near Threatened (NT) at the national level. Thus, 42% of recorded species face some level of conservation concern. These results significantly expand the knowledge of Central European psychodid fauna, highlight previously undocumented distribution data, and underscore the importance of protecting aquatic and riparian ecosystems for conservation of threatened species.</span></span></span></span></p> JAN JEŽEK JOZEF OBOŇA Copyright (c) 2026 Magnolia press 2026-03-06 2026-03-06 80 2 19 62 10.12976/jib/2026.80.2.1
