Malar space matt, densely punctate, as wide as basal width of mandible (Fig. 7 B). Gena wider than compound eye in lateral view, sub-polished, with moderately dense punctures (7 D). Frons and vertex rugose punctate. Postero-ocellar distance 0.9 × as long as ocular-ocellar distance, 1.3 × median ocellus diameter (Fig. 7 C). Antenna with 17 flagellomeres, slightly thickened toward apex, F 1 2.2 × as long as wide, 1.0 × as long as F 2. Occipital carina complete, ventrally curved before meeting hypostomal carina above base of mandible. Mesosoma. Pronotum rugose punctate, except narrow impunctate dorsally. Epomia present (Fig. 8 A). Mesoscutum 0.7 × as long as its maximum width, sub-polished, with large punctures laterally and rugose punctures medio-posteriorly. Notaulus distinct anteriorly. Scutellum moderately convex, sub-polished, with sparse punctures, lateral carina present basally (Fig. 8 B). Mesopleuron extremely rough, with dense, irregular wrinkles and coarse punctures; epicnemial carina with upper end reaching to subalar prominence. Sternaulus strong anteriorly, posteriorly weaker, reaching hind margin of mesopleuron, distinctly dorsad of lower posterior corner of mesopleuron. Metapleuron with reticular wrinkles (Fig. 8 A). Propodeum with moderately dense punctures, carinae strong. Area superomedia sub-polished with sparse punctures. Area basalis smooth, without punctures except punctate along surrounding carinae. Area dentipara densely punctate. Apico-median portion from posterior margin of area superomedial to apex of posterior corner of area petiolaris strongly concave longitudinally (Fig. 8 D). Propodeal apophysis strong and compressed. Propodeal spiracle small, round. Wings. Fore wing length ca. 2.9 mm, vein 1 cu-a slightly postfurcal to M & RS, inclivous, ventrally curved, vein 3 rs-m absent, vein 2 rs-m shorter than length of M between 2 rs-m and 2 m-cu, length of CU between 1 m-cu & M and 2 cu-a 2.5 × length of 2 cu-a (Fig. 8 E). Hind wing with distal abscissa of CU present, length of CU between M and cu-a 2.5 × length of cu-a. Legs. Hind coxa densely coarsely punctate, except concave area dorsally smooth. Hind femur sub-polished with moderately dense punctures, 3.9 × as long as its maximum width, 0.8 × as long as hind tibia length. Hind tibia coarsely sculptured, 1.1 × as long as hind tarsus. Hind basitarsus 0.4 × as long as tarsus. Metasoma. Tergites smooth and shining, with scattered, small punctures. T 1 2.5 × as long as apical width, median dorsal carina weak, present medially, dorsolateral carina complete, ventrolateral carina present, weak anteriorly; spiracle small, round. T 2 and T 3 almost fused together dorsally (Fig. 8 F). Laterotergite of T 2 2.1 × as long as apical width (Fig. 8 C). Ovipositor straight (Fig. 7 A). Ovipositor sheath 1.1 × as long as hind tibia. Colour. Black with reddish brown. Head black, antenna reddish, dorsal side of apical flagellomeres reddish brown, palpi yellow. Metasomal tergites from base to apex reddish brown to reddish. Ovipositor reddish. Ovipositor sheath reddish brown. Fore and mid legs reddish. Hind leg with coxa to femur reddish brown, tibia to tarsus reddish. Wings hyaline, wing veins blackish brown. Variation. Paratypes have fore wing length 2.5 – 2.9 mm, malar space 1.0 – 1.2 × as long as basal mandible width, T 1 2.4 – 2.6 × as long as apical width, laterotergite of T 2 1.9 – 2.4 ×, ovipositor sheath 1.0 – 1.2 × hind tibia length. The paratype from Lang Son Province has its F 1 1.2 × as long F 2. Male. Unknown. Comparative notes. This new species resembles C. rugosus sp. nov. by having its T 2 and T 3 almost fused together dorsally but differs from the latter by having T 4 onwards mostly exposed (vs. retracted under tergite 3) and punctate area dentipara (vs. densely wrinkled).	en	Pham, Nhi Thi, Cao, Nga Thi Quynh (2025): First record of the genus Cisaris Townes (Ichneumonidae: Phygadeuontinae) from Vietnam, with descriptions of four new species.
