Type material.

Holotype, ♀ (RMNH), "S. Vietnam: Dông Nai, Cát Tien N.P., Mal. traps, c. 100 m, 1-8.iv.2007, Mai Phu Quy & Nguyen Thanh Manh, RMNH’07”. Paratype: 1 ♀ (IEBR), Aga. 293, "CN Vietnam: Nghe An, Con Cuong, Pu Mat N.P., 19.iv.2006, P.Th. Nhi".

Diagnosis.

Similar to Disophrys subfasciata ( Brullé, 1846) from India, but that species has the scapus partly yellowish (entirely black in Disophrys quymanhi ), no ramellus (present) and the notauli are deeply impressed (shallow).

Description.

Holotype, ♀, length of body 11.5 mm, of fore wing 10.8 mm.

Head.

Antennal segments 61, length of third segment 1.8 times fourth segment, length of third, fourth and penultimate segments 2.7, 1.5 and 1.5 times their width, respectively; apical antennal segment 1.5 times as long as penultimate segment; length of maxillary palp 0.8 times height of head; in dorsal view length of eye 3.6 times temple (Fig. 128); POL:OD:OOL = 7:10:25; face coarsely punctate laterally and finely punctate medially; frons depressed near antennal sockets and laterally flat and punctate; pair of high lamelliform flanges between antennal sockets (Fig. 128); lateral carinae from anterior rim of lateral ocelli to antennal sockets laterally and its surroundings distinctly depressed; vertex with rather coarse punctures, but interspaces wider than interspaces; temple finely and spaced punctate.

Mesosoma.

Length of mesosoma 1.4 times its height; subpronope large and deep; side of pronotum moderately punctate dorsally, crenulate posteriorly and remainder largely smooth; lateral carina of mesoscutum lamelliform and surroundings smooth; mesoscutum shiny and largely spaced moderately punctate; medio-posteriorly hardly impressed, its middle lobe with a pair of faint shallow longitudinal grooves and lateral lobes weakly convex; notauli shallow and smooth, except for an anterior trans verse crest (Fig. 131); scutellar sulcus slightly shorter than dorsal face of scutellum and with 3 carinae; scutellum with some coarse punctures; its subposterior crest strong and transverse, connected to a strong longitudinal carina; side of scutellum crenulate; precoxal sulcus wide, strongly crenulate, but separated from prepectal carina; mesopleuron below precoxal sulcus and dorso-anteriorly rather densely coarsely punctate, remainder of mesopleuron largely smooth; metapleuron with long setae and rather densely coarsely punctate, ventrally with some rugae; propodeum with lateral carina lamelliform, with wide and anteriorly triangular areola; propodeal spiracle elongate, elliptical, 2.5 times as long as wide; distance between spiracle and lateral carina twice as long as width of spiracle.

Wings.

Fore wing: second submarginal cell quadrate and with a medium-sized ramellus (Fig. 134); r:3-SR:SR1 = 5:5:32; 2-SR:3-SR:r-m = 9:10:12. Hind wing: M +CU 1.3 times as long as 1-M (Fig. 134); surroundings of cu-a densely setose; 1r-m 0.8 times as long as 1-M.

Legs.

Length of hind femur, tibia and basitarsus 3.1, 6.2 and 7.6 times their width, respectively; outer side of hind coxa spaced finely punctate; hind femur (as remainder of leg) with short and dense setosity (Fig. 133); length of outer and inner spurs of middle tibia 0.5 and 0.7 times middle basitarsus, respectively; outer side of apex of hind tibia with three equal pegs; outer hind spur distinctly widened basally, almost straight; length of outer and inner spurs of hind tibia 0.3 and 0.5 times hind basitarsus, respectively; fore and middle tarsi rather slender; hind basitarsus with a distinct carina-like row of setae ventrally.

Metasoma.

First tergite smooth, evenly convex (but concave basally) and gradually widened apically (Fig. 130); length of first tergite 2.4 times its apical width; laterope long; second metasomal suture absent; ovipositor sheath elliptical, with long setae and 0.02 times as long as fore wing and about as long as basal width of hind tibia; ovipositor narrow, slightly curved.

Colour.

Brownish-yellow; antenna black; apical half of wings, hind tarsus largely and apex of hind tibia narrowly dark brown; stigmal spot large; apical half of pterostigma largely dark brown and narrow area below pterostigma yellow as remainder of wings (Fig. 134).

Variation.

Paratype has length of body 9.2 mm and of fore wing 9.3 mm, antenna with 55 segments, apical third of pterostigma dark brown, ramellus obsolescent, length of first tergite 2.6 times its apical width, vein M+CU of hind wing 1.3 times as long as vein 1-M, vein 1r-m of hind wing 0.9 times as long as vein 1-M.
