Diagnosis.

The new speciesis similar to Zelodia flavistigma sp. n., but differs by having the malar space about 3 times as long as basal width of mandible ( Zelodia flavistigma : 1.3-1.6 times); vein r of fore wing shorter than vein 3-SR (flavistigma: longer than vein 3-SR) and face with distinct fine punctation (flavistigma: face medially rugose-punctate).

Description.

Holotype, ♀, length of body 7.0 mm, of fore wing 6.7 mm.

Head.

Antennal segments 47, length of third segment 1.2 times as long as fourth segment; length of third, fourth and penultimate segments 2.2, 1.8 and 1.7 times their width, respectively; penultimate segment as long as apical segment without spine; antenna densely setose; scapus nearly cylindrical, twice as long as wide; maxillary palp as long as height of head; in dorsal view length of eye 3.0 times as long as temple (Fig. 444); in lateral view 0.7 times width of eye (Fig. 445); POL:OD:OOL = 3:2:5; malar space 3.1 times as long as basal width of mandible, 0.5 times as long as eye height and 0.3 times as long as height of head in lateral view (Figs 442, 445); face distinctly punctate; frons shiny smooth without lateral carinae; vertex shiny, almost smooth; pair of crests between antennal sockets short, convergent; occipital flange rather large, its ventral margin convex (Fig. 437).

Mesosoma.

Length of mesosoma 1.5 times its height; subpronope small, deep; side of pronotum smooth, upper side with sparse fine punctures; area near lateral carina of mesoscutum sparsely crenulate; middle lobe of mesoscutum punctate; lateral lobe of mesoscutum almost smooth; notauli wide, shallow and sparsely crenulate (Fig. 438); scutellar sulcus subequal to dorsal part of scutellum and with one carina; scutellum rugose-punctate; subposterior crest curved (Fig. 438); precoxal sulcus wide and shallow, sparsely crenulate (Fig. 437); mesopleuron below and above precoxal sulcus with sparse and distinct fine punctures; upper side of metapleuron rugose-punctate, lower side with strong rugae; propodeum shiny with areola and short medial carina basally (Fig. 438); propodeal spiracle round, 2.2 times as long as wide; distance between spiracle and lateral carina equal to width of spiracle.

Wings.

Fore wing: second submarginal cell narrowed anteriorly (Fig. 440); vein r very short, r:3-SR:SR1= 3:4:110; 2-SR:3-SR:r-m = 16: 3:15. Hind wing: M+CU 0.6 times as long as 1-M; surroundings of cu-a sparsely setose.

Legs.

Length of hind femur, tibia and basitarsus 3.4, 5.3 and 12.0 times their width, respectively; outer side of hind coxa punctate; hind femur (as remainder of legs) with long and dense setosity (Fig. 441); outer side of apex of hind tibia with two pegs, and upper peg twice as long as lower peg; length of outer and inner spurs of middle tibia 0.6 times and subequal to middle basitarsus, respectively; length of outer and inner spurs of hind tibia 0.5 and 0.7 times hind basitarsus.

Metasoma.

First tergite rather long; length of first tergite twice its apical width (Fig. 439); length of second tergite 0.8 times its apical width; second metasomal suture fine; ovipositor sheath densely setose, 0.4 times as long as hind basitarsus.

Colour.

Yellow; antenna (except yellow scapus) dark brown; wings yellow subhyaline; parastigma, apex of vein C+SC+R, apical half of pterostigma and vein 1-R1 dark brown.

Variation.

Male: antennal segments 43-45; length of first tergite 1.8 times as long as its apical width; first-third segments of hind tarsus dark brown.

Distribution.

NE Vietnam: Ha Giang, NW Vietnam: Yen Bai, CN Vietnam: Ha Tinh and S Vietnam: Kon Tum.

Biology.

Unknown.

Etymology.

From “brevis” (Latin for “short”) and “femur” (Latin for "foundation, base"), because of the short hind femur.
