This taxonomic treatment diagnoses the parasitoid wasp Pristaulacus takakuwai from a female holotype collected in Khao Kho National Park, Phetchabun. Diagnostic characters include a body longer than 14 mm, black and reddish-orange coloration, a dark substigmal wing spot, distinctive head and thoracic sculpture, a four-toothed tarsal claw and an ovipositor about 0.9 times the forewing length. Its host remains unknown.
Key findings
- The holotype is from Khao Kho National Park in Phetchabun. • The record supplies a detailed morphological diagnosis. • The host is unknown.
Why this matters globally
A standardized treatment supports identification and biodiversity monitoring of Southeast Asian Aulacidae and provides a basis for future ecological work.
Thai researcher contribution
A Chulalongkorn University-affiliated researcher contributes to the treatment of material from a Thai protected area.
Limitations to consider
The treatment is based on a single holotype, not a population survey, and lacks host, genetic and within-species variation data.
