Male diagnosis.

Unknown.

Female diagnosis.

TL ≈ 6.3 mm. Frons and vertex with deep foveolae (ca. 0.03 mm in diameter), of which intervals are imbricate; intervals in vertex wider than diameter of foveolae; intervals in lateral and submedian part of frons narrower than diameter of foveolae; the area along mesal line without foveolae. Median portion of clypeus roundly and relatively strongly produced anteriad; apical clypeal margin deeply incurved medially. Compound eye less developed. Mandible with four teeth. Dorsal face of pronotum, mesoscutellum, mesopleuron and dorsal and lateral faces of metapectal-propodeal complex imbricate, with dense foveolae. Transverse pronotal carina absent.

Female redescription.

Full description was given by Terayama (1995). Additional information as below.

Head. HL/HW × 100 = 131. Frons and vertex with deep foveolae (ca. 0.03 mm in diameter), of which intervals are imbricate; intervals in vertex wider than diameter of foveolae; intervals in lateral and submedian part of frons narrower than diameter of foveolae; the area along mesal line without foveolae. Occipital carina present. Median portion of clypeus roundly and relatively strongly produced anteriad; apical clypeal margin deeply incurved medially.

Mesosoma. Transverse pronotal carina absent. Dorsal area of pronotum imbricate with dense foveolae. Mesoscutum overlaid by posteromedian portion of pronotum. Mesoscutellum trapezoidal, 0.67 × as long as maximum width, weakly imbricate with dense foveolae. Mesopleuron imbricate, with sparse foveolae; anterior, upper and lower fovea absent; mesopleural pit absent. Lateral face of metapectal-propodeal complex imbricate entirely. Metapectal-propodeal complex in dorsal view weakly constricted behind propodeal spiracles and then widened again posteriad, without any distinct carinae which subdivide dorsal face; LP/WP = 2.5; dorsomedian face weakly imbricate, with sparse foveolae; median portion of propodeal declivity weakly and transversely rugoso-scabrous, with sparse foveolae.

Taxonomic remarks.

This species is morphologically most similar to the female of P. zhejiangensis . However, the female specimens of the genus Pristepyris have been rarely recorded and female-based species discrimination is hard to be conducted because of poor diagnostic characters in the females. We tentatively treated P. mieae as an independent species until additional specimens are available for molecular analyses.
