Female

Body length unknown, of head and mesosoma length 3.5 mm, fore wing length 4.9 mm. If characters not mentioned then as in the type species.

Head. (Antenna incomplete, with 50 segments remaining); length of first flagellar segment 1.3 times second segment; length of first and second flagellar segments 4.6 and 3.6 times their width, respectively; occipital carina distinct but not lamelliform, and dorsally weakly developed ( figure 30 ); length of eyes in dorsal view 3.5 times temple; POL:OD~0.75; OD:OOL~1.0; length of malar space 1.4 times basal width of mandible; length of maxillary palp 2.1 times height of head.

Mesosoma . Length of mesosoma 1.5 times (without propodeal spine; with spine 1.8 times) as long as high; pronope distinct ( figure 31 ); pronotum comparatively robust in dorsal view ( figure 31 ) and in dorso-lateral view medio-posterior area rather narrow and slightly convex ( figure 29 ); side of pronotum comparatively robust and crests rather short ( figure 30 ); precoxal sulcus impressed anteriorly but smooth and absent posteriorly; mesopleuron sparsely punctate ventrally, densely and finely punctate dorsally and antero-dorsally with some short rather weak crenulae; metapleuron finely punctate; mesoscutum punctulate, setose, with distinct short groove medio-posteriorly; axillar anterolateral lobes comparatively large and less robust ( figure 28 ); scutellum rather densely punctulate; propodeum coarsely vermiculate-reticulate, but medio-anteriorly narrowly largely smooth.

Wings. Fore wing: r 0.7 times as long as 3-SR; SR1 more than 3 times as long a 2-SR; m-cu 3 times as long as 2-SR; 1-CU1 twice as long as cu-a and about 0.1 times as long as 2-CU1. Hind wing: cu-a almost straight; subbasal cell sparsely setose; MzCU about 0.8 times as long as 1-M and about 3 times as long as 1r-m.

Legs. Length of hind femur, tibia and basitarsus 6.4, 11.0 and 11.8 times their width, respectively; both hind tibial spurs 0.2 times as long as basitarsus.

Metasoma. Missing, used for DNA research.

Colour. Black; palpi, basal fifth of hind tibia and of basitarsus, fourth fore tarsal segment, third to fourth middle and hind tarsal segments ivory; spines of propodeum, scape and pedicel (except outer side), humeral plate, pronotum anteriorly, axillar anterolateral lobes apically, mandible largely, fore and middle coxae, trochanters and trochantelli pale yellowish or whitish; scape, pedicel (except outer side) and fourth to sixth antennal segments pale yellowish; third basal antennal segment brown; 28th to 34th antennal segments whitish, and remainder of antenna dark brown; streak on outer side of scape and pedicel, tegulum, apex of hind femur, remainder of hind tibia and of tarsi, pterostigma and veins dark brown; fore and middle femora apically and fore and middle tibiae somewhat infuscate; wing membrane slightly infuscate.
