Description: . Body length 10.5 mm. Flagellum with 34 flagellomeres, bristle-shaped; 1 st flagellomere 3.4x longer than wide. Tyloids on flagellomeres 7-14, oval, maximally 0.5x as long as their flagellomeres and situated slightly basad to center. Temple strongly and almost linearly narrowed behind eye, dorsally 0.75x as long as eye. Distance of lateral ocellus to eye 0.9x ocellar diameter. Frons coarsely punctate and granulate, matte. Face and clypeus densely punctate and granulate, matte. Clypeus 2.1x wider than long, apical margin blunt and almost straight. Gena with superficial punctures. Malar space 0.65x as long as width of mandibular base. Mandible slender, with two teeth, lower tooth smaller than upper one and moderately curved inwards (by c. 45°). Genal carina complete, reaching hypostomal carina far from mandibular base, both carinae low.

Mesosoma covered with short grey hairs. Side of pronotum coarsely rugose-punctate dorsally, with coarse rugae ventrally. Notaulus distinctly impressed in frontal 1/6 of mesoscutum. Mesoscutum coarsely and densely punctate and granulate, matte. Mesopleuron and metapleuron coarsely rugose-punctate, speculum finely punctate; juxtacoxal carina present. Scutellum pyramidal-shaped, about as long as wide, densely punctate, with complete lateral carina and fine transverse crest at its top. Propodeum coarsely rugose and completely carinate. Area superomedia hexagonal, 1.5x wider than long, rugose; costula reaching its middle. Area petiolaris strongly impressed. Outer dentiparal edge with long tooth-like apophysis. Hind femur densely punctate, 5.4x longer than wide. Claws not pectinate.

Areolet pentagonal, frontal distance of intercubiti 4x their diameter; 2 nd recurrent vein in its middle. Nervulus postfurcal (by 3x its width).

Postpetiolus moderately widened, lateral field 0.4x as wide as the median one, punctate; median field elevated, smooth and shining, with coarse punctures. 2 nd tergite wide, 1.3x wider than long. Gastrocoelus rectangularly impressed, with strong ridges; thyridium transverse, c. 0.8x as wide as the interval. 2 nd and 3 rd tergites coarsely and densely rugose-punctate, ± matte. Following tergites with superficial punctures, ± shining. Apical margin of hypopygium with tongue-shaped median extension.

Color: Black. Flagellomeres 9-13, palps, mandible except teeth, labrum, clypeus, entire face and narrow line of frontal orbit, frontal margin and hind edge of pronotum, spot on tegula, subtegular ridge and apical half of scutellum ivory. Coxae and trochanters black; fore and mid coxae with ivory frontal spots; hind trochantellus reddish. Legs otherwise brown; fore and mid femora apically and fore and mid tibiae frontally ivory; hind femur narrowly reddish basally; all tarsi except brown tips of distal tarsomeres and brown basal half of hind metatarsus ivory. Wings hyaline, pterostigma black.

: unknown.

Remark: This new  has entirely black tergites. From other Palaearctic Hoplismenus  with black metasoma it can be differentiated by the ivory flagellar ring and completely ivory face and clypeus.
