Area of Science:

  • Entomology
  • Biodiversity Science
  • Zoology

Background:

  • Trichoptera (caddisfly) species records in Brazil have not been comprehensively updated in recent years.
  • Understanding the current diversity and distribution of Trichoptera is crucial for conservation efforts in Brazil.

Purpose of the Study:

  • To present an updated assessment of Brazilian Trichoptera species records.
  • To quantify the increase in recorded species over the past decade.
  • To identify families with the highest species richness and analyze geographical distribution patterns.

Main Methods:

  • Compilation and analysis of existing literature and databases on Brazilian Trichoptera.
  • Taxonomic identification and species count.
  • Geographical mapping of species distribution.

Main Results:

  • A total of 625 Trichoptera species are now recorded for Brazil.
  • This represents a 65.34% increase in new species records compared to the previous decade.
  • Hydropsychidae (124 spp.), Hydroptilidae (102 spp.), and Polycentropodidae (97 spp.) are the most species-rich families.
  • Trichoptera biodiversity knowledge is geographically uneven, with a concentration of records in the southeastern region.

Conclusions:

  • Brazilian Trichoptera diversity has significantly expanded in the last decade.
  • Further research is needed to address geographical gaps in knowledge, particularly outside the southeastern region.
  • The updated species list provides a baseline for future ecological and conservation studies.
