Three new species, namely
Li T-J, Carpenter
To date, there are 64 species and five subspecies recorded in the genus
The specimens examined are deposited in
Holotype, ♀, Thailand: Chiang Mai Doi Inthanon NP Vachiratharn Fls,
Female (Fig.
Head. Clypeus slightly convex, coriaceous, sparsely punctate, as wide as long, apex almost truncated (Fig.
Mesosoma. Pronotal carina complete, rounded dorsally and emarginated laterally; anterior surface of pronotum smooth; dorsal surface of pronotum, mesoscutum, mesepisternum, mesoscutellum, metanotum, and both dorsal and lateral surfaces of propodeum coarsely and densely punctate, punctures on mesepisternum, metanotum, and both dorsal and lateral surfaces of propodeum relatively denser and shallower, their interspaces distinctly carinate, reticulate, and similar to those of frons; mesoscutum evenly convex; mesoscutellum flat; metanotum slightly sloping; dorsal surface of propodeum almost in the same horizontal plane as metanotum, without distinct teeth behind metanotum, without superior carina; posterior surface widely and deeply depressed, forming a central cavity (Fig.
Metasoma. In dorsal view, T1 domed, its width 1.91× length and 0.82× width of T2, basally without a transverse carina, anterior surface coriaceous, impunctate, and almost vertical, dorsal surface with very sparse punctures; T2 apically with a narrow, translucent and blade-shaped lamella (Fig.
This species is similar to
Thailand.

Holotype, ♂, Philippines, ca. 4 miles E of Marikina, Rizal Prov. Luzon, 19.IX.1945, RP Dow leg., deposited in
Male (Fig.
Head. Clypeus (Fig.
Mesosoma. Pronotal carina complete, rounded dorsally and emarginated laterally; anterior surface of pronotum wholly coriaceous and impunctate; dorsal surface of pronotum moderately punctate medially and densely punctate laterally and apically; mesoscutum, mesepisternum, mesoscutellum, metanotum sparsely to moderately punctate, similar to those of vertex and gena, punctures of mesoscutellum slightly sparser than those of other above parts; mesoscutum slightly convex; both mesoscutellum and metanotum flat; dorsal surface of propodeum punctate, punctures shallow, flat bottomed and interspaces slightly carinate, in the same horizontal plane as metanotum, with two small and translucent teeth behind metanotum, without superior carina; posterior surface smooth, with medial longitudinal carina, widely and deeply depressed forming a central cavity (Fig.
Metasoma. In dorsal view, T1 domed, its width 1.78× length and 0.80× width of T2, basally without a transverse carina, anterior surface vertical, smooth, and separated from dorsal surface, dorsal surface coriaceous and with very sparse, tiny punctures; T2 without a translucent and blade-shaped lamella apically, punctures on T2 and other terga similar to those of T1; S2 widely depressed basally, punctures of sterna similar to those of terga; apical yellow bands on T1–T4 wider medially, with small gaps medially, apical band of T6 interrupted laterally, and all apical yellow bands of sterna with U-shaped gaps medially.
This species is similar to
Philippines.
