DIAGNOSIS. The new species is closely related to Brachypipona longicornis (Morawitz,

1895) but differs by having pronotal carina weakly developed and not acutely producing laterally, epicnemial suture not carinate, mesepisternum more sparsely punctured, with shining interstices reaching diameter of punctures, parategula and tergum 6 black (in B.

longicornis, pronotal carina producing laterally in the form of small but distinct acute angles,

epicnemial carina in the form of a well developed keel, mesepisternum densely punctured,

with narrow interstices several times less than diameter of punctures, parategula and tergum

6 with large yellow spots). Another closely related species B. orientalis Gusenleitner, 2004

has pronotal carina with even more distinct lateral angles than in B. longicornis , clypeus with deeper apical emargination, and also parategula and tergum 6 with large yellow spots (Gusenleitner, 2004).

DESCRIPTION. Female. Body length (from head to apical margin of tergum 2) 7–8

mm; fore wing length 6.5–7 mm.

Head 1.2× as wide as long in frontal view. Vertex with dense deep punctures, interstices less than diameter of punctures. Temples, frons and ocular sinuses with sparser and finer punctures, interstices reach several puncture diameters. Clypeus with sparse fine punctures,

interstices reach several puncture diameters; 1.5× as wide as long; apical emargination shallow, taking 1/3 of clypeal anterior margin, broader than distance between antennal foveae; apical teeth blunt. Scape with sparse fine punctures. Pronotal carina weakly developed, distinct only laterally. Pronotum and mesonotum with dense punctures as on vertex. Tegula with sparser and somewhat finer punctures. Mesepisternum with deep punctures, shining interstices reach puncture diameter. Scutellum convex. Metanotum with punctures somewhat denser and finer than on mesonotum and diminishing towards propodeum; punctures form serrate dorsal surface visible in anterior view. Metapleuron and lateral part of propodeum rugose, without distinct punctures. Dorsolateral part of propodeum punctured as mesonotum; propodeal concavity rugose, with indistinct punctures. Punctation on terga 1–5 rather deep and dense; interstices vary in size but approximately equal to puncture diameter, with distinct microsculpture. Punctation on tergum 6 very dense and fine.

Sternum 2 elevated behind basal sulcus and then evenly rounded in lateral view, with indistinct, short and very shallow longitudinal furrow at base. Punctation on sterna 2–5

several times sparser than on terga, interstices have distinct microsculpture. Sternum 6

shagreened, without punctures.

Pubescence of body weakly developed. Mouthparts with pale setae ± equal in length to scape diameter. Clypeus anteriolateral margins, edge of anterior face of pronotum, and pleuron with shorter setae, ± equal to ocellus diameter. Legs with very short, minute pale pubescence. Sterna with even shorter, unnoticeable pale pubescence. Other structures bare.

Basal color black. The holotype has orange-yellow pattern: mandible except teeth, labrum,

clypeus, large triangular spot on frons, stripes along inner margins of eyes from clypeus to ocular sinuses, large spots on temples at dorso-lateral corners of head, scape, dorsal face of pronotum, tegula, large spot on dorsal mesepisternum, scutum, metanotum, two large spots on dorsolateral parts of propodeum, apical bands on terga 1, 2, 4, and sterna 2 and 3. Apical band on tergum 3, lateral spots on terga 2 and 4, and basal half of sterna 2 and 3 ferruginous.

Both paratypes have rather lemon-yellow pattern than orange-yellow, except mandible and labrum in the second paratype (from Almaty Prov.), and do not have ferruginous pattern on metasoma. The paratype from Jambyl Prov. also has yellow spot on tergum 5. The second paratype has central black spot on clypeus and apical band on sternum 3 reduced to small lateral spots. Pedicel , ventral side of flagellum, and legs from base of femorae orange in all three specimens. First flagellomere nearly entirely orange in the holotype and the first paratype but black dorsally in the second paratype. Wings distinctly fuscous, especially on marginal cell .

Male. Unknown.

ETYMOLOGY. The species is named after Nikolay V. Kurzenko, a Russian taxonomist on Eumeninae who firstly recognized this species but never describe it.

DISTRIBUTION. Kazakhstan (Aktobe, Jambyl, and Almaty Provinces).

BIONOMICS. Unknown.
