Overview

Biodiversity survey reveals eleven new state-level distribution records for horse flies in Brazil, highlighting the utility of citizen science in closing entomological knowledge gaps.

Key Points

  • To assess whether photographic citizen science data from iNaturalist can expand the known geographic distributions of horse flies (Diptera: Tabanidae) across Brazilian states.
  • Extracted and filtered iNaturalist observations of Tabanidae within Brazil across eight preselected genera.
  • Confirmed species identifications from photographs and systematically compared records against the benchmark Brazilian Taxonomic Catalog of Fauna (CTFB).
  • Screened 159 observations across eight genera, identifying 25 observations that established new state-level records for 11 distinct species.
  • Identified new state records for Scepsis appendiculata (BA, RS), Catachlorops potator (RS), Erioneura fuscipennis (ES), Eutabanus pictus (MT), Lepiselaga albitarsis (SC), Lepiselaga crassipes (PE, ES), Leucotabanus flavinotum (RO), Selasoma tibiale (AL, PE, PR, RS), Stibasoma aureoguttatum (PR), Stibasoma bela (MG), and Stibasoma flaviventris (BA).
  • Demonstrated that photographic records supply novel biological data from under-sampled areas, including live coloration, sexual dimorphism, morphology, behavior, and microhabitat preferences.
