Body distinctly larger than the worker, with the head width ranging from 1.04 to 1.06 mm. Eye much larger than in the worker (ca. 0.28 mm long and with ca. 22 ommatidia along the long axis). Distance between posterior ocelli longer than that between anterior and posterior ocelli. Mesopleuron above always with a distinct transverse groove. Compared with the worker, petiole relatively thin, seen from above almost lacking dorsal flat portion. Body sculpture much as in the worker. Mesopleuron and metapleuron smooth and shining; in one specimen from Taiwan posterior face of propodeum and petiole also smooth medially, and mesopleuron partly and metanotum densely punctate. Pilosity. Body covered with decumbent pubescence except on mesopleuron and metapleuron where pubescence is absent or very sparse. Eye with short fine standing hairs. Mesosoma dorsally and gastral tergites with very sparse standing hairs; long hairs on tergites almost confined to their posterior margins; sternites with more long standing hairs on the disc. Outer margin of forewing with dense short fringe; outer and posterior margins of hindwing fringed with longer hairs. Coloration much as in the worker.</paragraph>
<paragraph id="C8690F9F3D1EB77B936008D6E0FB2363" pageNumber="654">Male. Description based on the specimens from the same series as the queen. Structure. Head including eyes much wider than long. Eyes very large (maximum diameter ca. 0.40 mm) with outer margin strongly convex and inner margin weakly emarginate. Clypeus transverse with anterior and posterior margins truncate; labrum anteriorly produced as a narrow lobe. Mandible long and fragile, not opposable, basally wide and suddenly narrowed toward bluntly pointed apex. Ocelli relatively large; distance between posterior ocelli slightly longer than their diameter, and as long as ocello-occipital distance; antenna long; scape (segment 1) twice as long as segment 2 and slightly shorter than segment 3. Pronotum short; mesoscutum large, with weak notauli and sharp parapsidal lines; mesopleuron large, with a wide transverse furrow which is striate on the bottom; scutellum dorsally convex with an anterior transverse zone which is much lower than the main disc; axilla extensively concave; metanotum short. Propodeum rounded; dorsal, lateral and posterior faces not clearly differentiated. Petiole relatively low, in profile rather strongly narrowed above, seen from back almost as wide as high, with dorsal margin almost straight; subpetiolar process flat, with acute posterior tooth in profile. Sculpture. Head superficially micropunctate. Sculpture on pronotum, mesoscutum, metanotum and metapleuron still weaker; mesopleuron extensively smooth and strongly shining; axilla coarsely rugose. Propodeum more strongly and densely sculptured, but on its posterior face sculpture somewhat weaker. Anterior face of petiole mat; posterior face weakly shining. Gaster only superficially and sparsely punctate and somewhat shining. Pilosity similar to that in the queen. Mesopleuron, metapleuron and posterior face of petiole almost hairless. Petiole extensively with dense obliquely standing short hairs on its anterior and lateral faces; subpetiolar process below with standing hairs. Fringe on wings as in the queen. Coloration. Body brown to pale brown, with ivory white femora and tibiae; tarsi especially fore tarsus darker. Scape and pedicel yellowish; other segments dark brown.</paragraph>
