Description. Female. Body color: yellow, with antenna light brownish yellow except basal 1/4 dark brown; remainder brownish yellow as scape and pedicel (both with internal face yellow), tarsal claws, telotarsus. Fore wing: 1 – 1A brownish yellow as M+CU distal 1/3, C+SC+R yellow; hind wing: veins yellow. Wings hyaline. Body length = 4.11 – 5.88 mm; fore wing length = 3.44 – 4.44 mm.

Head: Width of oral opening/height of oral opening = 1.88 – 2.07. Antenna, flagellomeres all longer than wide, between 34 – 38; malar space slightly smaller than basal width of mandible; occipital carina effaced dorsally and only present laterally (dorsal gap, as big as distance between external edges of lateral ocelli), not fused with hypostomal carina, clearly separated; median ocellus as big as lateral ocellus; space between lateral ocellus black; ocell-ocular distance 2/3 Lateral ocellus width.

Mesosoma: Length of mesosoma in dorsal view/width of mesosoma = 2.57 – 2.75; height of mesosoma = 0.91 – 1.15 mm; propleuron dorso-lateral area, basal area with defined colliculate sculpturing, remainder nitid; notauli punctate, pits from bigger laterally to smaller medially, less defined medially; medial longitudinal pit present, with water drop shape and longitudinal punctate sculpturing present; sternauli conspicuously striate at distal 1/2, basal 1/2 as union with prepectal carina nitid or with few inconspicuous striate sculpturing, area below nitid; mesopleuron immaculate except dorso-lateral area with confused rugose sculpturing; metapleuron granulate, ventral edge with rugose sculpturing present; propodeum with dorsal 1/2 granulate, remainder with colliculate sculpturing; spiracles sub – oval; first lateral areas of propodeum with light areolate-rugulose sculpturing, remainder with spaced areolate-rugulose sculpturing, less conspicuous ventrally than medially; medial carina as big as or smaller than 1/4 Propodeum length; areola absent or very irregular; ventral tubercles present without carinae over them and densely granulate.

Legs: basal lobe of hind tarsal claws elongate and acute at tip.

Wings: fore wing: 3RSa/1RS = 4.25 – 4.40; r = 0.24 – 0.26 mm. hind wing: 1M/r – m = 2.13 – 2.33; m+cu antefurcal to 2RS; 2RS straight; angle at union of veins 2RS – 2M wide; pterostigma yellow with irregular medial brownish yellow spot.

Metasoma: Length of first metasomal tergum/width of first metasomal tergum = 1.26 – 1.05; length of second metasomal tergum/width of second metasomal tergum = 0.68 – 0.79; length of third metasomal tergum/width of third metasomal tergum = 0.30 – 0.34; basal width of first metasomal tergum = 0.29 – 0.41 mm; hypopygium = 0.35 – 0.55 mm. first metasomal tergum dorso – basal triangular area of first metasomal tergum open with carinae present, medial carina normal; first metasomal tergum lineate sculpturing as second metasomal tergum sculpturing; third metasomal tergum lineate sculpturing finer and less conspicuous than second metasomal tergum sculpturing, not reaching third metasomal tergum distal edge; fourth metasomal tergum with lineate sculpturing finer than present at third metasomal tergum.

Male. Similar to females.
