Body black or dark brown ( Fig. 5); third antennomere (including annellus) 1.5 × longer than fourth segment ( Fig. 6G View FIGURE 6 ); eye in dorsal view 0.8 × as long as temple; eye in lateral view 1.4 × higher than wide ( Fig. 4I View FIGURE 4 ); frons around antennal sockets rugose, vertex and temple smooth ( Fig. 6I View FIGURE 6 ); face weakly punctate, 2.5 × wider than high, rather convex medially, with a short medio-longitudinal ridge ( Fig. 6J View FIGURE 6 ); clypeus small and semi-ellipitcal, with some punctures and long setae ( Fig. 6J View FIGURE 6 ); precoxal sulcus narrowly crenulated, almost reaching anterior edge of epicnemial area and middle coxa ( Fig. 6C View FIGURE 6 ); notauli sculptured and incomplete, only present anteriorly; medioposterior depression deep and linear, not extending to middle of mesoscutum, mesoscutum smooth, with some long setae along notauli ( Fig. 6D View FIGURE 6 ); surface of propodeum densely reticulate-rugose, with medio-longitudinal carina and several transverse carinae, areola absent posteriorly ( Fig. 6E View FIGURE 6 ); pterostigma wide and elliptical, 4.0 × longer than its maximum width ( Fig. 6A View FIGURE 6 ); hind coxa smooth ( Fig. 6N View FIGURE 6 ); length of first tergite almost equal to its apical width, its surface finely longitudinally striate ( Fig. 6E View FIGURE 6 ), dorsal carinae widely separate medially; setose part of ovipositor sheath 0.88 × as long as fore wing (total visible sheath 0.9 times), and 2.4 × as long as hind tibia ( Fig. 6H View FIGURE 6 ).
Description. Holotype, ♀, length of body 5.3 mm, of fore wing 5.7 mm.
Head. Transverse, width of head 2.1 × its lateral length, and 1.4 × wider than mesoscutum ( Fig. 6I View FIGURE 6 ); antenna with 47 antennomere, third antennomere (including annellus) 1.5 × longer than fourth antennomere, length of third, fourth and penultimate antennomere 3.8, 2.5 and 1.7 × their width, respectively ( Fig. 6G View FIGURE 6 ); length of maxillary palp 1.3 × height of head ( Fig. 5); eye in dorsal view 0.8 × as long as temple; eye in lateral view 1.4 × higher than wide ( Fig. 6I View FIGURE 6 ); frons around antennal sockets rugose, vertex and temple smooth ( Fig. 6I View FIGURE 6 ); OOL:diameter of ocellus:POL= 19:5:7; face weakly punctate, 2.5 × wider than high, rather convex medially, with one short mediolongitudinal ridge ( Fig. 6J View FIGURE 6 ); clypeus small and semi-elliptical, with some punctures and long setae ( Fig. 6J View FIGURE 6 ); mandible enlarged apically, dorsal tooth enlarged, lobe-shaped ( Fig. 6L View FIGURE 6 ), ventral tooth medium-sized and lobeshaped, separate from first tooth ( Fig. 6M View FIGURE 6 ), middle tooth curved and acute, with small incision between first and second tooth ( Fig. 6M View FIGURE 6 ), medial length of mandible 1.4 × its maximum width.
Mesosoma. Length of mesosoma 1.5 × its height ( Fig. 6C View FIGURE 6 ); pronope absent ( Fig. 6I View FIGURE 6 ); medio-anteriorly pronotum widely crenulate, remainder of pronotum smooth; epicnemial area crenulated and rugose; precoxal sulcus narrowly crenulate, almost reaching anterior edge of epicnemial area and middle coxa; pleural sulcus distinct crenulated; episternal scrobe linear and deep; metapleuron densely rugose ventrally, remainder smooth ( Fig. 6C View FIGURE 6 ); notauli sculptured and incomplete, only present anteriorly; medio-posterior depression deep and linear, not extending to middle of mesoscutum, mesoscutum smooth, with some long setae along imaginary course of notauli; scutellar sulcus deep and narrow, with one medio-longitudinal carina, sulcus 5.0 × wider than its maximum length; scutellum smooth ( Fig. 6D View FIGURE 6 ); surface of propodeum densely reticulate-rugose, with medio-longitudinal carina present and several transverse carinae, areola absent posteriorly ( Fig. 6E View FIGURE 6 ).
Wings ( Figs 6A–B View FIGURE 6 ). Pterostigma wide and elliptical, 4.0 × longer than its maximum width. r:3-SR:SR1 = 1:4:11; 1-SR+M slightly sinuate; SR1 curved; r 0.5 × as long as width of pterostigma, vein r issuing from posterior part of pterostigma; cu-a postfurcal; 1-CU1:2-CU1 = 5:14; 3-CU1 as long as CU1b; 2-SR:3-SR:r-m = 22:20:11; mcu weakly antefurcal, converging to 1-M posteriorly; first subdiscal cell 2.8 × as long as wide; M+CU1 sclerotized. Hind wing: M+CU: 1-M: 1r-m = 22:20:16; m-cu distinct antefurcal.
Legs. Hind coxa smooth ( Fig. 6N View FIGURE 6 ), without ventro-basal tubercle, with densely long setae; tarsal claws slender, longer than arolium; length of femur, tibia and basitarsus of hind leg 4.3, 11.2 and 8.0 × their width, respectively; apical appendages of hind tarsal segments absent, segments ventrally with dense bristles ( Fig. 6N View FIGURE 6 ).
Metasoma. Length of first tergite almost equal to its apical width, its surface finely longitudinally striate, dorsal carinae widely separate medially ( Fig. 6E View FIGURE 6 ); dorsope distinct; convexity of upper valve of ovipositor steep basally; setose part of ovipositor sheath 0.88 × as long as fore wing (total visible sheath 0.9 times), and 2.4 × as long as hind tibia ( Fig. 6H View FIGURE 6 ).
Colour. Black or dark brown ( Fig. 5); pterostigma and veins brown; wing membrane hyaline.
Variation. Body length of male 3.3 mm, and length of fore wing 4.0 mm, antennal segments of male 44 (1); body length of female 4.3–5.3 mm, and length of fore wing 5.3–5.7 mm, antennal segments of female 45 (1) or 47(1).
Comparative diagnosis. This species is similar to A. luciella Stelfox but differs by having a comparatively transverse head (width of head 2.1 × its lateral length versus 1.5 × in A. luciella ), long ovipositor (setose part of ovipositor sheath 0.9 × as long as fore wing versus 0.6), and body entirely black (versus brown to light brown partly).
Etymology. Named “ melasoma ” because of the entirely black body: “ melas ” is Greek for “black” and “ soma ” is Greek for “body”.
