colorHind legs black [T4]. ♀ The legs are black, almost without light coloration. ♂: Hind tibiae entirely dark-colored [T14].
wings
shapeMarginal cell noticeably shorter than pterostigma [T4]. Vein 1-R1 is 1.3 times shorter than the pterostigma. The radial vein departs from the pterostigma at a distinctly acute angle to its longitudinal axis [T14, key]. ♂: Vein 1-R1 of fore wing 0.7 times as long as pterostigma [T14].

metasoma
shape♀: Metasoma with small denticulate projection at apex, 2 times as long as wide (Fig. 1) [T4] (l:w in fig. 1 = 1.7! [Arp]). Apex without emargination on lower side. Posterior margin somewhat curved on lower side, but less than 1/3 of metasoma. At apex without tubercle.. ♂: Metasoma 2 - 2.5 times as long as wide [T4, key]. ♀: The metasoma at the apex with a denticle. Metasoma oval, apically bent forward 0.2 times its length, 1.5–1.6 times as long as wide [T14]. Apically bent forward by 0.1 of its length [NOT 0.2 !].[T14, key 353b] The length of the metasoma is usually 1.5-1.7, less often 1.8-1.9 times its width, at most almost twice [T14, key 94b]. ♂ Metasomal length, as a rule, less than twice its width, usually 1.6-1.7 times [T14, key 536b]
sculptureMetasoma with longitudinal rugae, usually not extending beyond its middle [T4, key]. Metasoma finely reticulate-rugose, with several weak longitudinal rugae only at the base [T14].
colorThe metasoma is completely black [T14, key].
♀ ovipositorThe ovipositor longer than the hind metatarsus [T14].
♂ apertureWidth of aperture on apex of metasoma 2 - 3 times its height, its height 2/5 height of metasoma in apical part, black [T4, key]. The apical aperture is clearly transverse, located below the middle of the metasoma [T14, key].
1. Body black, at most metasoma with light colored pattern. 2. Antennae 16-segmented. Abdominal apex without aperture—females. 4. Head usually not broadened behind eyes; if, occasionally, somewhat broadened, then antennae less thin, with shorter apical segments and metasoma rounded toward apex (as much as or almost as much as toward its base) with posterior margin somewhat curved forward. 8. Head of usual shape, not projecting laterally and angularly beyond genae; temples usually not, or only slightly, rarely 2 times as long as eye. Occiput very slightly excavate. metasoma at apex without tubercle. 34. metasoma uniformly rounded in posterior part, apically somewhat curved on lower side 38. Palpi much shorter[than height of head]; proboscis slightly developed, not projecting or slightly projected. 41. Radial cell significantly longer [not extremely short]. 42. Posterior margin of abdominal shield much less curved [than 1/3 of length of metasoma]. 44. metasoma with longitudinal rugae, usually not extending beyond its middle (not extending beyond middle, if rugae coarse). If rugae distinctly extending beyond mid-metasoma, then antennae thin with long segments or body smaller. 45. metasoma 2—2.5 times as long as wide in middle. 47. Body with less uniform though with less coarse and nonalvcolar sculpture on head and major part of mesonotum. Apex of metasoma without emargination on lower side. 48. Segments in apical part of antennae square or slightly longer than wide.
49. metasoma with small denticulate projection at apex, 2 times as long as wide (Fig. 196: 5). Whole body densely and finely punctate, matte. Temples slightly longer than eye. Genae 1/3 as high as longitudinal diameter of eye, height of face 1/2 its width. Radial cell noticeably shorter than stigma. mesosoma 1.3—1.5 times as long as high. Body including antennae, palpi and hind legs entirely black. Wings darkened. Body 2.2—2.7. Moldavia.
