Redescription (male)

Colour. Body dark testaceous to black. Head: black with clypeus testaceous, mandible yellow with apical margin testaceous; antenna yellow except distal segments dark testaceous. Mesosoma : pronotum and mesonotum black except pronotal collar dark testaceous; pronotum black; forewing hyaline, wing veins testaceous; legs yellow except coxa and femora testaceous. Metasoma: dark testaceous with distal pale testaceous transverse band.

Morphology. Body ( Figure 3A ) 3.80 mm long.

Head ( Figure 3B ): 1.03 × as long as wide with convex posterior margin and posterolateral margin bluntly angulated in full face view; frons and vertex strongly reticulate with dense shallow punctures, separated from each other by 0.3–1.0 × their diameter (0.03–0.04 mm); mandible with one tooth ( Figure 3C ); anterior margin of clypeus projecting with obtuse angle; from scape to flagellomere III in ratio of 3.1: 1.0: 1.5: 1.5: 1.4 in length; from scape to flagellomere III and XI 3.1, 1.2, 1.9, 1.9, 1.8 and 3.5 × as long as wide respectively ( Figure 3D ); compound eye 0.37 mm long and smooth without hairs; LE 1.4 × as wide as OOL; WF 2.4 × as wide as WOT; anterior angle of ocellar triangle obtuse, POL 1.5 × as wide as AOL, OOL 1.3 × as wide as WOT ( Figure 3B ).

Mesosoma ( Figure 3E, H, J ): pronotum 0.4 × as long as wide without transverse carina, smooth, not reticulate, relatively deep punctures distributed over anterior half, posterior half with few small punctures; mesoscutum and scutum with few small punctures; notaulix well developed, scutellar pits connected to each other ( Figure 3E ); propodeal disc short, 0.7 × as long as wide with convex lateral margin in dorsal view. Median, lateral and transverse carinae present; median discal carina reaches transverse carina, basal triangular area weakly depressed, coarsely reticulate, sublateral area reticulated with irregular rugae ( Figure 3J ). Forewing: metacarpus short, about 0.3 × as long as pterostigma, discoidal vein arising posteriorly from transverse median vein ( Figure 3H ).

Metasoma ( Figure 3I ): petiolate, relatively flat in lateral view, smooth and shining.

Genitalia ( Figure 3F, G ): paramere short and thick, distal margin narrowly rounded with dense hairs; aedeagus short, bottle-shaped, basal margin broadly concave; digitus shorter than aedeagus, inner margin and distal part of aedeagus well sclerotized ( Figure 3F ), hypopygium short, median area sclerotized with three basal projections and concave margin, discal margin well-developed, median concave margin curved with many hairs ( Figure 3G ).
