Holotype, ♀, length of body 5.0 mm, length of fore wing 4.6 mm.

Head. Width of head 2.4 times its median length, sparsely setose and strongly shiny; antenna complete (Fig. 2A ), 47-segmented, segments densely setose, length of third segment 0.7 times as long as fourth segment, length of third and fourth segments 3.8 and 6.5 times their width, respectively; length of maxillary palp 1.5 times height of head; eye in dorsal view 2.0 times as long as temple; temple in dorsal view subparallel-sided behind eyes (Fig. 2C ); OOL: diameter of ocellus: POL = 14:6:11; frons flat medially (except an incomplete median groove, anteriorly half deep groove and posteriorly half with groove trace) and convex laterally, smooth; antennal sockets distinctly protruding; with a smooth, narrow and superficial groove between antennal sockets and eye; minimum width of face 0.35 times maximum width of head, densely rugulose- punctate, with a Y-shaped carina medially (from antenna sockets to clypeus), medio-posteriorly with fine reticulate, with rather dense and long setae (Fig. 2B ); clypeus wide, triangle, width 1.1 times its length, with long setae and ventrally rounded and its surface largely smooth except a few punctures (Fig. 2B ); length of malar space 0.1 times basal width of mandible; mandible sparsely rugose medially except teeth part smooth, strongly widened dorsally, its medial length 1.8 times its maximum width, upper tooth large and truncate lobe-shaped, with ventral tooth rather small, rounded and lobe-shaped, connected to a carina (Fig. 2E ).

Mesosoma. Length of mesosoma 1.6 times its height; pronotum dorsally with large deep and round dorsope; side of pronotum with some coarse crenulate anteriorly, posteriorly finely crenulate and remainder smooth (Fig. 2F ); epicnemial area dorsally smooth, medially crenulate and ventrally punctate-rugose; precoxal sulcus anterior 1/5 smooth and remainder crenulate, widely crenulate anteriorly, narrowed after its middle and absent posteriorly (Fig. 2F ); remainder of mesopleuron smooth; episternal scrobe round, deep; pleural sulcus anteriorly smooth and punctulate, with dense setae, posteriorly coarsely crenulate; mesosternal sulcus coarsely crenulate, rather wide posteriorly; metapleuron largely smooth and punctulate, with fine reticulate ventrally; notauli complete, deep and narrow, smooth, without midpit, more depressed in the end of notauli (Fig. 2G ); mesoscutum strongly shiny and largely glabrous, but with some long setae near notauli and lateral carina and medial lobe protuberant; mesoscutum without a separate medio-posterior depression (Fig. 2G ); axilla rather setose and lateral carina moderately protuberant; scutellar sulcus deep, with one carina and coarsely rugae, without punctures, 0.2 times as long as scutellum; scutellum rather convex in lateral view; metanotum distinctly lamelliform protruding posteriorly in lateral view; propodeum largely smooth and with sparse punctures anteriorly, except for a short median carina with rugae near it, medially with crown-shaped areolate area and bottom carina protuberant, medio-posteriorly densely reticulate, latero-posteriorly smooth with a longitudinal carina respectively (Fig. 2G ); propodeal spiracle round, small and medially at propodeum.

Wings. Pterostigma subelliptical, its posterior margin hardly curved; vein r issued distinctly behind middle of pterostigma and distinctly oblique; r:3-SR:SR1 = 7:22:50; 1-SR+M rather sinuate; SR1 straight, slightly curved posteriorly; cu-a short and oblique, strongly postfurcal; 2-SR:3-SR:r-m = 38:36:19, vein r-m of fore wing distinctly inclivous; m-cu slightly postfurcal, slightly converging to 1-M posteriorly; first subdiscal cell 5.0 times as long as wide; 3- CU1:CU1b = 3.2 and 3-CU1 oblique. Hind wing: M+CU:1-M:1r-m = 83:53:45; m-cu distinctly developed and interstitial (Fig. 2D ).

Legs. Outer side of hind coxa largely smooth, punctulate and moderately setose, dorsally shiny and smooth; middle coxa strongly protruding forwards ventrally, hind coxa gradually narrowed; tarsal claws moderately robust; length of femur, tibia and basitarsus of hind leg 3.9, 10.0, and 6.9 times their width, respectively; middle tibia and basitarsus rather short and adpressed setose (Fig. 2A ).

Metasoma. Length of first tergite 1.1 times its apical width, its surface regularly costate-striate, its dorsal carinae complete and united submedially (Fig. 2G ); laterope absent; dorsope large and deep; remainder of metasoma smooth and rather depressed; ovipositor with minute dorsal notch and some ventral teeth; setose part of ovipositor sheath as long as fore wing and 0.4 times as long as hind tibia (Fig. 2A ); apex of ovipositor sheath subtruncate and no apical spine; hypopygium medium-sized and apically acute in lateral view (Fig. 2A ).

Colour. Black; head and first tergite apically chestnut brown; scapus, pedicellus, and mandible apically brownish yellow; tegulae brown, but dorsal half brownish yellow; fore leg light brown (except coxa brownish yellow with yellow spot basally, trochanter, trochantellus with dark yellow spot apically, tibia basally and tarsus apically darkened yellow); middle leg light chestnut brown (but coxa brown with dark yellow spot basally, trochanter, trochantellus with dark yellow spot apically, tarsus apically light brown); hind leg chestnut brown as head (but coxa with brown spot basally, trochanter, trochantellus similar as middle leg, tarsus apically light brown); palpi pale yellowish; remainder of antenna, mandible basally, ovipositor sheath dark brown, metasoma (except blackish first tergite) yellowish brown dorsally, apical segment and metasoma ventrally and laterally yellow (Fig. 2I ); pterostigma and most veins brown; wing membrane subhyaline.

Distribution.

Thailand.

Etymology.

Named after the mainly conspicuously yellow metasoma of the holotype; “knekos” is Greek for yellow and “soma” is Greek for body.
