Description. ♀, length of body 3.1 mm, of fore wing 3.2 mm.
Head. Transverse ( Fig. 2I View FIGURE 2 ), width of head 1.7 × its lateral length ( Fig. 2I View FIGURE 2 ), and 1.6 × wider than mesoscutum; antenna with 40 segments, third segment (including annellus) 0.8 × longer than fourth segment, length of third and fourth segments 2.5 and 4.0 × their width, respectively ( Fig. 2M View FIGURE 2 ); length of maxillary palp 1.7 × height of head; eye in dorsal view 2.1 × as long as temple ( Fig. 2I View FIGURE 2 ); eye in lateral as high as wide; frons largely smooth, slightly rugose near antennal sockets; vertex and temple smooth ( Fig. 2I View FIGURE 2 ); OOL: diameter of ocellus: POL= 12:5:5; face 1.8 × wider than high, rather convex medially, densely and coarsely rugose-reticulate with transverse striation; clypeus small, subtriangular, protruding forward, densely and finely reticulate-punctate ( Fig. 2J View FIGURE 2 ); malar space absent; mandible with 4 teeth or lobes, enlarged apically, dorsal tooth enlarged, lobe-shaped ( Fig. 2L View FIGURE 2 ), ventral tooth medium-sized and lobe-shaped, ventral carina protruding, middle tooth curved ( Fig. 2M View FIGURE 2 ), medial length of mandible 1.5 × its maximum width.
Mesosoma. Length of mesosoma 1.7 × its height ( Fig. 2D View FIGURE 2 ); pronope round, wide and deep; medio-anteriorly pronotum inconspicuously crenulate, remainder of pronotum smooth ( Fig. 2D View FIGURE 2 ); epicnemial area rugose; precoxal sulcus widely crenulate, not reaching middle coxa; pleural sulcus crenulated ventrally; episternal scrobe round and deep; metapleuron smooth medially but reticulate-rugose ventrally ( Fig. 2D View FIGURE 2 ); notauli crenulated and incomplete, anteriorly impressed on disc, ( Fig. 2C View FIGURE 2 ); medio-posterior depression deep, nearly extending to middle of mesoscutum, scutellar sulcus deep, with one longitudinal carina, sulcus 4.1 × wider than its maximum length; scutellum smooth ( Fig. 2C View FIGURE 2 ); surface of propodeum weakly rugose, with a medio-longitudinal carina present on half of propodeum, areola present posteriorly ( Fig. 2E View FIGURE 2 ).
Wings ( Fig. 2 View FIGURE 2 A-B). Pterostigma wide, 3 × longer than its maximum width. r:3-SR:SR1 = 1:3:11; 1-SR+M nearly straight; SR1 straight; r 0.5 × as long as width of pterostigma; cu-a postfurcal; 1-CU1:2-CU1 = 3: 19; 3-CU1 distinct shorter than CU1b; 2-SR:3-SR:r-m = 20:15:12; m-cu postfurcal, converging to 1-M posteriorly; first subdiscal cell 3.3 × as long as wide; M+CU1 largely unsclerotized. Hind wing: M+CU: 1-M: 1r-m = 10:6:5; m-cu far antefurcal.
Legs. Hind coxa smooth, without ventro-basal tubercle; tarsal claws moderately robust, longer than arolium ( Fig. 2N View FIGURE 2 ); length of femur, tibia and basitarsus of hind leg 4.6, 9.0 and 6.3 × their width, respectively; apical appendages of hind tarsal segments absent, segments ventrally with dense bristles ( Fig. 2N View FIGURE 2 ).
Metasoma. First tergite widened from base to apex, apical width twice longer than its basal width, length of first tergite 0.9 × its apical width, with distinct dorsal carinae fused in basal half, medially convex ( Fig. 2E View FIGURE 2 ); dorsope distinct ( Fig. 2F View FIGURE 2 ); median length of second tergite 0.9 × its basal width, 0.7 × as long as its maximum posterior width, 1.3 × length of third tergite; combined length of second and third tergites 1.2 × their maximum width ( Fig. 2F View FIGURE 2 ); setose part of ovipositor sheath 0.5 × as long as fore wing (total visible sheath 0.6 ×), and 1.5 × as long as hind tibia ( Fig. 2H View FIGURE 2 ).
Colour. Yellowish ( Fig. 1 View FIGURE 1 ); metasoma (except yellowish first tergite) and antenna (except yellowish 6 basal segments) dark brown; pterostigma and anterior part of veins brown, remainder of veins and wing membrane hyaline.
Variation. Male paratype similar to female types, body length of ♂ 3.0 mm; of fore wing 3.2 mm; antennal segments of ♂ 43 (1). Females have body length 2.9–3.1 mm, and length of fore wing 3.0– 3.2 mm, eye in dorsal view 2.1–2.4 × as long as temple; face 1.7-1.8 × wider than high.
Comparative diagnosis. This species is similar to H. hymaenei Belokobylskij , but differs from it in having comparatively short temple, eye in dorsal view 2.1–2.4 × as long as temple (versus 1.2–1.7 in H. hymaenei ); face 1.7-1.8 × wider than high (versus 2.1-2.7 ×); body yellowish to yellowish brown (versus reddish brownish to black).
Etymology. Named “ carinata ” because the propodeum has a long medio-longitudinal carina: “ carina ” is Latin for “ridge”.
