Head blackish brown, mesosoma and first and second metasomal tergites yellowish. Body length 4.1 mm.— Indonesia (Sumatra)...................................................................... H. hemiflava van Achterberg, 1983

- Transverse diameter of eye (dorsal view) 0.7–1.1 × length of temple. Recurrent vein postfurcal. Palpi far not reaching middle coxa. Head reddish or brown, mesosoma and metasoma black or dark reddish brown, sometimes mainly brown (except H. lao-

sensis Fischer)...................................................................................... 5 5. Temple distinctly (in 1.3–1.5 ×) longer than transverse diameter of eye (dorsal view). Median length of second metasomal tergite subequal to its maximum width........................................................................ 6

- Temple about as long as transverse diameter of eye (dorsal view). Median length of second metasomal tergite distinctly less than its maximum width................................................................................ 7

6. Distal upper lobe of mandible with two narrow and short teeth. Medioposterior furrow of mesoscutum distinctly longer than half of mesoscutum. First to third metasomal tergites longitudinally striate. Third tergite with medio-posterior groove. First metasomal tergite 1.5 × its apical width. Body length 6.1 mm.— Myanmar.............. H. ruficeps ( Cameron, 1910) (♂)

- Distal upper lobe of mandible with single wide and long teeth. Medioposterior furrow of mesoscutum not longer than half of mesoscutum. First to third metasomal tergites reticulate-striate. Third tergite without medio-posterior groove. First metasomal tergite not longer than its apical width. Body length 6.1 mm.— China (Fujian)......... H. complexus Chen et Wu, 1994 (♀)

7. Sternaulus incomplete, irregularly rugose, but smooth before mesopleural furrow. Lower part of mesosoma sparsely setose. Mesosoma, first and most part of second metasomal tergites yellow. Body length 6.1 mm.— Laos................................................................................................... H. laosensis Fischer, 2008 (♂)

- Sternaulus complete, entirely crenulate. Lower part of mesosoma densely setose. Mesosoma and metasoma black or partly dark reddish brown................................................................................... 8

8. Eyes without setae. POL 1.0–1.3 × OD. Transverse diameter of eye almost equal to length of temple (dorsal view). Recurrent vein of fore wing distinctly postfurcal. Propodeum without delineated areola. Metasoma wide, combined length of second and third tergites 1.2–1.3 × their maximum width. Hind tibia distinctly widened apically, its maximum width about 3.0 × minimum width. Body length 5.3–7.2 mm.— Japan (Kyushu, Honshu), South Korea (new record)....... H. maetoi Achterberg, 1983

- Eye with short and sparse setae. POL 0.75 × OD ( Fig. 15 ). Transverse diameter of eye 1.3 × length of temple (dorsal view) ( Fig. 15 ). Recurrent vein of fore wing weakly postfurcal ( Fig. 25 ).
