Researchers reviewed the Thai genus Pristaulacus and recognized 17 species. An integrative taxonomic approach described the new P. chiangmaiensis, recorded P. vilhelmseni from Thailand for the first time, and produced updated diagnoses, images, an identification key, distribution map, and Oriental checklist.
Key findings
- Seventeen Thai Pristaulacus species were recognized. The new P. chiangmaiensis received an integrative description, and a Chiang Mai specimen extended P. vilhelmseni from Laos into Thailand. Multiple barcodes and an Oriental checklist improve name and distribution verification.
Why this matters globally
Asian Aulacidae remain underdocumented. Reliable names, keys, and barcodes are infrastructure for biodiversity monitoring, evolutionary study, and habitat-change assessment, particularly where species may disappear before being recorded.
Thai researcher contribution
Chulalongkorn University's insect ecology and entomology teams collaborated with Italian and Canadian specialists, contributing Thai specimens, diagnoses, barcodes, and national distribution mapping.
Limitations to consider
Checklist completeness depends on sampled places, seasons, trapping methods, and museum access. Some species have few specimens or unknown hosts. A single barcode locus may not resolve every complex, and occurrence points do not define full distributions.
