Type material.
Holotype, ♀ (RMNH), "N. Vietnam: Viet Tri, n[ea]r Thanh Son, Thuong Cuu, 20°59'N; 105°8'E, 350-400 m, 11-16.x.1999, Malaise traps, R. de Vries, RMNH’99”.
Diagnosis.
The new species is morphologically similar to Braunsia bipunctata Enderlein, 1906, from Indonesia, but differs by having the propodeum with a complete and regular basal transverse carina ( Braunsia bipunctata : transverse carina partly weakly developed and irregular); and the anterior half of the first tergite coarsely striate medially (bipunctata: smooth except for a median carina).
Description.
Holotype, ♀, length of body 10.5 mm, of fore wing 9.3 mm, ovipositor 7.3 mm.
Head.
Antennal segments 45; length of third segment times fourth segment, length of third, fourth and penultimate segments 3.3, 2.3 and 1.3 times their width, respectively; length of maxillary palp 0.7 times height of head; in dorsal view length of eye twice temple (Fig. 62); POL:OD:OOL = 7:5:12; antennal sockets rather tubular (Fig. 62); occipital flange large, its ventral margin convex bellow (Fig. 60); face shiny smooth with sparse punctures; frons and vertex shiny and smooth.
Mesosoma.
Length of mesosoma 1.5 times its height; subpronope large and deep; side of pronotum smooth; area near lateral carina of mesoscutum smooth; side of mesoscutum largely smooth with sparse setae and fine punctures; notauli deep and smooth (Fig. 56); scutellar sulcus short, 0.4 times as long as dorsal face of scutellum and with 4 carinae; scutellum convex, smooth, sparsely setose; mesopleuron above and below precoxal sulcus shiny and smooth; precoxal sulcus narrow and shallow similar to a smooth groove (Fig. 55); metapleuron smooth; propodeum with basal and transverse carinae, two longitudinal carinae forming a large areola; spiracle medium-sized, subelliptical and 2.3 times as long as wide.
Wings.
Fore wing: second submarginal cell pentagonal, narrow anteriorly, with rather long ramellus, 0.8 times as long as vein 2-SR (Fig. 58); r:3-SR:SR1 = 6:2:55; 2-SR:3-SR:r-m = 9:2:9; vein cu-a distinctly postfurcal. Hind wing: vein 2-SR+M slightly vertical; vein M+CU 0.8 times as long as 1-M; surroundings of cu-a sparsely setose.
Legs.
Length of hind femur, tibia and basitarsus 5.1, 9.7 and 11.6 times their width, respectively; hind femur (as remainder of legs) with short and dense setosity; outer side of apical third of middle tibia with a row of 5 pegs and a cluster of 3 pegs at apex; outer side of apex of hind tibia with a cluster of 9 pegs; length of outer and inner spurs of middle tibia 0.4 and 0.6 times middle basitarsus, respectively; length of outer and inner spurs of hind tibia 0.3 and 0.4 times hind basitarsus, respectively.
Metasoma.
First tergite rather long, widened apically, 2.3 times as long as its apical width (Fig. 57); first tergite longitudinally striate; dorsal carinae of first tergite strong, diverging apically and fused with striae apically (Fig. 57); second tergite as long as third tergite, longitudinally striate, with a deep striate transverse groove on apical third; third tergite with parallel striae on basal two thirds and with a wide striate transverse groove on apical third; apical third of third tergite and remainder of metasoma smooth, with sparse setae apically; ovipositor sheath long, rather narrow (Fig. 54) and 0.8 times as long as fore wing.
Colour.
Bright brownish-yellow; malar space pale yellow; antenna (except yellow scapus) and hind tarsus dark brown; fore wing with dark brown stigmal spot (Fig. 58); wing membrane yellowish, apically faintly infuscate (Fig. 58).
Distribution.
NE Vietnam: Viet Tri.
Biology.
Unknown.
Etymology.
It is a pleasure to name this species after Mr Rob de Vries, who participated in all Vietnam expeditions and prepared the specimens. He plays an important role in the success of the expeditions.
