Description. Structure as in Pseudozumia cucphuongensis sp. nov., but differs as follows: Female ( Fig. 13 ). Body length 20.6–21.0 mm; fore wing length 20–20.4 mm. Head in frontal view about 1.1 × as wide as high ( Fig. 11 ). Vertex well developed, strongly produced behind eye, with cephalic fovea coalesced and placed inside V shape depression. Distance from posterior ocelli to apical margin of vertex 3 × distance from posterior ocelli to inner eye margin. Gena narrower than eye, in lateral view about 0.7 × as wide as eye. Occipital carina reaching corner of gena, and evanescent dorsally. Inner eye margins in frontal view about 1.1 × further apart from each other at vertex than at clypeus ( Fig. 11 ). Clypeus in frontal view almost as wide as high, apical margin truncated ( Fig. 11 ), width of truncation about 1/3 × width of clypeus between inner eye margins; in lateral view disc of clypeus gradually and weekly convex from base to the middle then straight to apical margin. Antennal scape curved, long, about 5 × as long as its maximum width; flagellomere I slightly more than 2 × as long as its maximum width, flagellomeres II–IV longer than wide, flagellomeres V–VII as long as wide, flagellomeres VIII-IX slightly wider than long, terminal flagellomere bullet-shaped, slightly curved, 1.1 × wider (at its basal width) than long.

Mesosoma longer than wide in dorsal view. Pronotal carina raised, reaching ventral corner of pronotum. Mesoscutum slightly convex, as long as wide between tegulae.

Metasomal tergum I gradually widening from base to apex ( Fig. 12 ), in dorsal view 1.7 × as long as wide and without node at lateral sides, with longitudinal striation on dorsal part strongly developed, with a strong median carina flanked on each side by 5-6 distinct carinae. Tergum II in dorsal view as wide as long and slightly shorter than tergum I; sternum II gradually and slightly convex to apical margin. Tergum II with slightly raised apical lamella, terga III–VI without apical lamellae and not raised.

Remarks. P. indica borneana is morphologically similar to the typical one, but it has different color as mentioned by Giordani Soika (1960): mandible ferruginous, with yellow spot at the base; clypeus with a large ferruginous spot near apical margin, the wider yellow line on scape; and wings without purple reflections, but rather golden.

The color of the specimens of the typical subspecies, P. i. indica from Yen Bai province we examined well agreed with the description by Giordani Soika (1960) except the large brown spot at apical margin of clypeus (it was entirely black as mentioned in Giordani Soika (1960)).
