Description. ♀, length of body 8.2 mm, of fore wing 7.7 mm.
Head. Transverse, width of head 1.7 × its lateral length ( Fig. 6I View FIGURE 6 ), and 1.5 × wider than mesoscutum; antenna incomplete, with 18 remaining segments, third segment (including annellus) 0.8 × longer than fourth segment, length of third and fourth segments 2.0 and 3.3 × their width, respectively ( Fig. 6G View FIGURE 6 ); length of maxillary palp 1.4 × height of head; eye in dorsal view 1.2 × as long as temple ( Fig. 6I View FIGURE 6 ); eye in lateral view 1.1 × higher than wide ( Fig. 6K View FIGURE 6 ); frons mainly smooth, rugulose near antennal sockets and densely punctate laterally ( Fig. 6I View FIGURE 6 ); vertex and temple smooth ( Fig. 6I View FIGURE 6 ); OOL:diameter of ocellus:POL= 18:7:3; face 2.7 × wider than high, rather convex medially, densely and coarsely rugose-reticulate with transverse striation laterally ( Fig. 6J View FIGURE 6 ); clypeus small, subtriangular, protruding forward, densely and finely reticulate-punctate ( Fig. 6J View FIGURE 6 ); malar space absent; mandible with 4 teeth or lobes, enlarged apically, dorsal tooth enlarged, lobe-shaped ( Fig. 6L View FIGURE 6 ), ventral tooth medium-sized and lobe-shaped, ventral carina protruding, middle tooth curved ( Fig. 6M View FIGURE 6 ), medial length of mandible 1.7 × its maximum width.
Mesosoma. Length of mesosoma 1.6 × its height ( Fig. 6D View FIGURE 6 ); pronope round and deep; medio-anteriorly and posteriorly pronotum distinctly crenulate ( Fig. 6D View FIGURE 6 ); epicnemial area widely crenulate; precoxal sulcus long and crenulated, nearly complete but not reaching middle coxa; pleural sulcus crenulated ventrally; episternal scrobe medium-sized and round; metapleuron densely punctate ( Fig. 6D View FIGURE 6 ); notauli crenulated, distinctly impressed on disc; mesoscutum smooth and with sparse setae anteriorly; medio-posterior depression short, densely crenulated; scutellar sulcus deep and narrow, with 5 short carinae, sulcus 4 × wider than its maximum length; scutellum smooth and rather flat, with long setose ( Fig. 6C View FIGURE 6 ); surface of propodeum densely and coarsely reticulate-rugose, areola absent ( Fig. 6E View FIGURE 6 ).
Wings ( Figs 6 View FIGURE 6 A-B). Pterostigma 5.4 × as long as its maximum width, r:3-SR:SR1 = 5:13:30; 1-SR+M slightly sinuate; SR1 straight; r nearly equal to the width of pterostigma; cu-a weakly antefurcal; 1-CU1:2-CU1 = 1: 20; 3- CU1 longer than CU1b; 2-SR:3-SR:r-m = 28:19:12; m-cu slightly postfurcal, sinuate and converging to 1-M posteriorly; first subdiscal cell 2.9 × as long as wide; M+CU1 sclerotized. Hind wing: M+CU: 1-M:1r-m = 30:16:13; m-cu weakly antefurcal.
Legs. Hind coxa finely punctate, without ventro-basal tubercle; tarsal claws moderately robust, longer than arolium ( Fig. 6N View FIGURE 6 ); length of femur, tibia and basitarsus of hind leg 4.5, 6.5 and 5.0 × their width, respectively; apical appendages of hind tarsal segments absent, segments ventrally with dense bristles ( Fig. 6N View FIGURE 6 ).
Metasoma. First tergite moderately widened from base to apex, its apical width 1.7 × its basal width, length of first tergite 0.85 × its apical width, with distinct dorsal carinae fused in basal half, medially convex ( Fig. 6E View FIGURE 6 ); dorsope present ( Fig. 6E View FIGURE 6 ); median length of second tergite 0.75 × its basal width, 0.65 × its maximum posterior width, 1.07 × length of third tergite ( Fig. 6F View FIGURE 6 ); combined length of second and third tergites 1.3 × maximum width; setose part of ovipositor sheath 0.6 × as long as fore wing (total visible sheath 0.7 ×), and 1.5 × as long as hind tibia ( Fig. 6H View FIGURE 6 ).
Colour. Black ( Fig. 5); head reddish yellow; pterostigma and veins brown; wing membrane slightly infuscated.
Variation. Body length: 6.1–8.2 mm, length of fore wing 5.8–7.7 mm.
Comparative diagnosis. This species is similar to H. hymaenei Belokobylskij , but differs by having a short and densely crenulated medio-posterior depression of mesoscutum (versus simple and long in H. hymaenei ); vein cu-a of fore wing antefurcal (versus postfurcal); second tergite of metasoma 1.1 × as long as third tergite (versus distinct longer than third tergite); and hind coxa densely punctate (versus smooth).
Etymology. Named “ poricrenulata ” because of the crenulated medio-posterior depression: “porus” is Latin for “pit” and “crena” is Latin for “notch”.
