Description. Holotype, ♀, length of body 4.3 mm, of fore wing 5.3 mm.
Head. Transverse and smooth, width of head 1.7 × its lateral length ( Fig. 4I View FIGURE 4 ); antenna with 55 segments, third segment (including annellus) 0.9 × longer than fourth segment, length of third, fourth and penultimate segments of antennal 2.5, 3.6 and 2.5 × their width, respectively ( Fig. 4G View FIGURE 4 ); length of maxillary palp 1.8 × height of head; eye glabrous, 1.7 × as long as temple in dorsal view ( Fig. 4I View FIGURE 4 ), eye in lateral view 1.2 × higher than wide ( Fig. 4K View FIGURE 4 ); frons flat ( Fig. 4I View FIGURE 4 ); vertex rather convex ( Fig. 4I View FIGURE 4 ); OOL:diameter of ocellus:POL= 10:3:3; face 2.1 × wider that high, densely and coarsely rugose-reticulate with transverse striation laterally ( Fig 4J View FIGURE 4 ); clypeus small, subtriangular, protruding forward, densely and finely reticulate-punctate ( Fig. 4J View FIGURE 4 ); malar space absent; mandible rugose and with 4 teeth or lobes, enlarged apically, dorsal tooth large and lobe-shaped ( Fig. 4L View FIGURE 4 ), ventral carina protruding and middle tooth medium-sized, curved ( Figs 4 View FIGURE 4 M-N); medial length of mandible 1.7 × its maximum width.
Mesosoma. Length of mesosoma 1.5 × its height ( Fig. 4D View FIGURE 4 ); pronope deep and medium-sized, side of pronotum largely smooth except some indistinct crenulae present medio-anteriorly and posteriorly ( Fig. 4D View FIGURE 4 ); mesoscutum with lateral carina in front of tegulae present; epicnemial area largely crenulated; precoxal sulcus long and widely crenuate, almost reaching middle coxa; pleural sulcus crenulate; episternal scrobe round and deep; metapleuron reticulaterugose and with a round pit anteriorly ( Fig. 4D View FIGURE 4 ); notauli crenulated, distinctly impressed on disc but absent posteriorly, medio-posteriorly depression long and deep, extending to middle of mesoscutum ( Fig. 4C View FIGURE 4 ); mesoscutum with sparse setose; scutellar sulcus crenulated, with three carinae, sulcus 3.8 × wider than its maximum length; scutellum and its side smooth ( Fig. 4C View FIGURE 4 ); surface of propodeum reticulate-rugose and areola absent ( Fig. 4E View FIGURE 4 ).
Wings ( Figs 4 View FIGURE 4 A-B). Pterostigma 5.0 × as long as wide, vein r issuing from its posterior third, r 0.8 × maximum width of pterostigma; r: 3-SR: SR1= 5:10:38; m-cu of fore wing postfurcal; 1-CU1:2-CU1 = 2:17; 3-CU1 much longer than CU1b; cu-a postfurcal; 2-SR:3-SR:r-m = 25:15:9; first subdiscal cell 3.4 × as long as wide. Hind wing: M+CU:1-M:1r-m = 20:13:12; m-cu present, and weakly postfurcal.
Legs. Hind coxa with some punctures anteriorly ( Fig. 4O View FIGURE 4 ); tarsal claws robust; length of femur, tibia and basitarsus of hind leg 5.0, 6.7 and 5.0 × their width, respectively; apical appendages of first-fourth hind tarsal segments absent.
Metasoma. Length of first tergite equal to its apical width, dorsope distinct ( Fig. 4F View FIGURE 4 ); surface of metasoma longitudinally striate and some reticulate-rugosity between striae, dorsal carinae narrowly united posteriorly, convex medially ( Fig. 4E View FIGURE 4 ); median length of second tergite 0.9 × its basal width, 0.7 × its maximum posterior width, 1.1 × length of third tergite; combined length of second and third tergites of metasoma 1.4 × maximum width; setose part of ovipositor sheath 0.5 × as long as fore wing (total visible sheath 0.7 ×), flattened and 1.5 × as long as hind tibia ( Fig. 4H View FIGURE 4 ).
Colour. Black ( Fig. 3A View FIGURE 3 ); head and mandible and 3 basal segments of antennal orange brown, hind femur, hind tibia (except pale yellow basal one sixth), palpi and remainder of legs yellowish; pterostigma and veins brown; wing membrane slightly infuscated.
Variation. Body length: 3.8–4.3 mm, of fore wing 4.0– 5.3 mm.
Comparative diagnosis. This species is similar to H. hymaenei Belokobylskij , but differs by having a comparatively long vein r (0.8 × maximum width of pterostigma versus 0.5 × in H. hymaenei ), slender pterostigma (versus robust), suture between second and third tergites deep and distinct (versus shallow); and metasoma entirely black (versus light reddish brown except partly darkened third tergite).
Etymology. Named “ melasaraia ” because of the entirely black metasoma: “melas” is Greek for “black” and “ araia ” is Greek for “belly”.
