Holotype, ”, length of body 5.6 mm, of fore wing 4.64 mm.

Head. Antenna with 41 segments, length of third segment 1.1 times fourth, length of third, fourth and penultimate segments 4, 3.5 and 1.5 times their maximal width, apical segment three times its maximal width; eyes sparsely setose; length of eye in dorsal view 2.6 times temple; temple directly narrowed posteriorly, slightly punctate, shiny; OOL: diameter of ocellus: POL~2.0:1.0:1.0; frons smooth medially, laterally punctate; vertex convex, slightly punctate, flattened near stemmaticum; face flattened, punctate; clypeus flattened and punctate, its ventral border straight; maxillary palp 1.6 times height of head; length of malar space 1.5 times basal width of mandible; malar suture mainly absent (except near eye); occipital flange straight ventrally and angled posteriorly ( figure 117 ).

Mesosoma ( figure 97 ). Length of mesosoma 1.3 times its maximal height; side of pronotum coriaceous and medially crenulate; mesopleuron coriaceous and sparsely punctate; precoxal sulcus incomplete anteriorly, punctate and terminating as a cluster of fine punctures ( figure 97 ); metapleuron coriaceous and sparsely punctate; mesoscutum coriaceous; scutellar sulcus rectangular with some small carinae posteriorly; scutellum convex and coriaceous; surface of propodeum coriaceous posteriorly, with some weak transverse rugae; metapleural flange rounded.

Wings. Fore wing: r: SR1z3-SR~6:35; 2-SR: r-m~6.5:4.5; second submarginal cell petiolate; subbasal cell glabrous anteriorly; vein 3-CU1 three times longer than vein CU1b. Hind wing: 2-M coloured; membrane largely glabrous basally.

Legs. Hind coxa coriaceous, with some fine rugae apically; hind femur coriaceous, its ventral border very finely irregular; lengths of hind femur, tibia and basitarsus 4.9, 6.8 and 9.3 times their widths, respectively; tibial spurs 0.48 and 0.31 times basitarsus; hind tibia with six apical teeth.

Metasoma. First tergite 2.4 times longer than apically wide, coriaceous, in lateral view medially concave; spiracles protruding; all following tergites coriaceous; T2 1.3 times longer than T3; second suture smooth, straight; ovipositor sheath 1.0 times fore wing length.

Colour. Yellowish. Humeral plate brownish; telotarsi infuscate; fore wing hyaline, its apical margin weakly brownish; antennal segments 3–21 brownish dorsally and yellowish ventrally, following segments brownish to infuscate.

Variation. Apex of hind tibia more orange in some specimens; hind tibia may have some bristles on its outer face. Number of antennal segments varies between 41 and 42.

Remarks. From the ecological data given by De Saeger (1956), it appears that this species is associated to riverine and/or marsh vegetation (elevation between 710 and 1000 m).
