Wings. Fore wing: pterostigma wide and oval shaped, vein r emitted from posterior 1/3 of pterostigma, length of vein r 0.6 × as long as pterostigma width, forming an obtuse angle with vein 3-SR; vein SR1 extending above wing tip; vein SR1 4.1 × longer than vein 3-SR; vein 2-SR: vein 3-SR: r-m = 6: 5: 3; 1-SR+M slightly sinuate; vein m-cu slightly antefurcal. 2nd submarginal cell 2.4 wider than height, narrow posteriorly, vein cu-a slightly postfurcal, vein 1-CU1: 2-CU1 = 1: 8 (Fig. 2B); vein 3-CU1: vein CU1b=1:1. Hind wing: vein M+CU 1.3 × vein 1-M; vein m-cu antefurcal (Fig. 2B).
Legs. Hind coxa and femur slender, entirely with dense, long setae; hind tibia slender; hind femur 5.9 × longer than its maximum width; hind femur 0.8 × longer than hind tibia, hind femur 1.6 × longer than hind basitarsus.
Metasoma. Length of T1 about 2.1 × its apical width, apical width 1.4 × its basal width, dorsope large and protruding, dorsal carinae not converging, extending to apical 1/3 of T1; area between dorsal carinae smooth, remainder of T1 regularly longitudinally striate (Fig. 2H); ovipositor long, maximal visible part roughly 1.8 × mesosoma, ovipositor sheath with dense setae (Fig. 2I) and its setose part as long as hind tibia (Fig. 2I).

Variation. Body length: 2.0– 2.6 mm; length of fore wing 2.0– 2.6 mm; width of head 2.1–2.4 × as wide as long; 31–41 antennomeres, apical antennomeres 3 to apical antennomeres 12–15 pale yellow; scutellar sulcus with one or three ridges; frons of one specimen without round pit; male mostly same as female, except scutellar sulcus with one ridge, antenna apical half light brown, basal half brown, notauli present on anterior 1/3 and smooth, vein 3-CU1: vein CU1b=2:3.
Distribution. Thailand.
Host. Unknown.
Etymology. The name refers to the relatively short medio-longitudinal carina of the propodeum; “brevis” is Latin for short and “carina” is Latin for keel, or ridge.
