Habitat
Woody with dense undergrowth; specimens have been collected by sweeping vegetation along trails in forested areas.
Distribution
Widespread across Ethiopian, Nearctic, Neotropic, Oriental, and Palaearctic biogeographic regions. Documented from Taiwan (Taipei, New Taipei City, Nantou County, Hualian County, Pingtung County), Ryukyu Islands of Japan (Yakushima, Okinawa Hontou, Irabu-jima, Ishigaki-jima, Iriomote-jima), Tokyo, and Vermont, USA.
Host Associations
- click beetle larvae - Elateridae larvae are the known ; specific host unconfirmed for most Pristepyris species
Behavior
have been observed in undergrowth of woody ; collection method suggests ground-level or low vegetation activity. involves attacking click beetle larvae, though specific oviposition and development details are unreported.
Ecological Role
As of click beetle larvae, members of this may contribute to of soil-dwelling pests. Bethylidae as a have been characterized as potential natural enemies of lepidopteran and coleopteran pests in agricultural and forestry systems, though this characterization is family-level and not specific to Pristepyris.

Taxonomic history
The was established by Kieffer in 1905. Recent revision (Liao, Terayama & Eguchi 2022) clarified boundaries in East Asia, described P. seqalu as new, transferred P. minutus to Eleganesia, and synonymized P. takasago under P. minutus. Male specimens of P. seqalu were described from a single locality in Taiwan.
Research gaps
of most remains unknown; specificity, seasonal , and stages are undocumented for the majority of species. Female specimens of P. seqalu remain unknown.
