synonyms
body
shapeBody length ♀ 3.3 mm [T17][T14], ♂ 3.2 mm [T14].
colorThe body is black, uniformly not roughly sculpted, matt [T17].
head
shapeHead 1.2 times as wide as mesonotum, rectilinearly narrowed behind eyes; head width 2.2 times its length and 1.3 times its height. Length of temples equal to transverse diameter of eye. Length of base of ocellar triangle equal to OOL plus diameter of ocellus. POL 2.5 times ocellus diameter. Longitudinal diameter of eye 1.5 times transverse diameter, 1.7 times height of malar space. Face width 2.2 times its height, 1.5 times longitudinal diameter of eye. The proboscis is poorly developed. Maxillary palps equal to height of face with clypeus [T17][T14].The distance between the tentorial fossa is slightly greater than the distance from the tentorial fossa to the eye (11: 9). Face in upper third with weak median carina [T17].
sculptureThe face and vertex of the head behind the ocelli have weak and numerous transverse rugae; the temples have the same vertical rugae [T17][T14].
color
antenna
shape ♀Antennae slightly longer than head and mesosoma, thin; length of 3rd segment 3 times, 8th segment.2 times, the two apical segments slightly longer than their width; 7 apical segments deeply depressed, apical laterally compressed [T17]. Antennae equal to the total length of the head and mesosoma; 3rd antennal segment 3 times its width, 8th segment twice, two apical segments slightly larger than their width. The segments in the apical half of the antennae are flattened [T14].
shape ♂Antennae 21-segmented [T21][T14].
color
mesosoma
shapemesosoma length 1.5 times its height; propodeum with distinct transverse carina and well developed lateral teeth [T17][T14].
sculptureMesonotum before scutellum with slightly coarser and short rugae, scutellum with smooth sculpture, shining [T17][T14].
color
legs
shapeHind femur 4 times as long as wide; inner spur of hind tibia equal to half of 4th segment of hind tarsus; hind tarsus? and tibiae of equal length; 5th segment of hind tarsus slightly less than 2nd, more than 3rd [T17]. Hind femur 4 times as long as wide. The hind tibia is equal to the hind tarsus. ♂ Tarsus very thin, 5th segment of hind tarsus shorter than 3rd, almost half as long as 2nd. Hind femur 4 times as long as wide [T14].
sculpture
colorApices of femora and tibiae yellowish brown, apices of hind tibiae and tarsi of all legs darkened [T14]. The hind tibia are almost entirely brownish-yellow, except for brown apex [T21].
wings
shape1-R1 much shorter than the pterostigma (3:5). Marginal cell is almost twice as large as the 2nd submarginal cell. 3-SR shorter than r, 3-SR 4 times shorter than SR1, which is curved outward. Vein cu-a as long as 1-CU1 [T17]. 1-R1 is half as long as the pterostigma. SR1 is curved outward. ♂ SR1 uniformly curved [T14].
colorThe wings are darkened [T17][T14]. The wings in basal half almost glassy light [T21].
metasoma
shapeMetasoma slightly more narrowed towards apex than towards base, apically not bent forward. Its length 1.9 times its width, 3 times its maximum height (in apical third of metasoma). ♂: The length of the metasoma is twice its width [T14].
sculptureMetasoma with rather coarse and anastomosing longitudinal rugae, almost reaching its apex [T17][T14].
color
♀ ovipositorOvipositor thin, projecting beyond the apex of the metasoma by the total length of the 2nd and 3rd segments of the hind tarsus [T17][T14].
♂ apertureAperture large, 3.5 times as wide as high, 0.4 times as wide as metasoma[ T14]. The median process of the apical abdominal foramen is massive triangular (fig 10, 11) [T21].
