Type material.

Holotype, ♀ (RMNH), "S. Vietnam, Dong Nai, Cat Tien N.P., Malaise trap, c. 100 m, 1-9.x.2005, C. v. Achterberg & R. de Vries, RMNH’05”. Paratypes: 1 ♀ (IEBR), Aga. 175, "Central North Vietnam: Ha Tinh, Huong Son, secondary forest, 5-10.v.2004, Tr.X. Lam"; 3 ♂ (RMNH, IEBR), Aga. 198, Aga. 199, Aga. 200, id., but 25.v.2004; 1 ♂ (IEBR), Aga. 172, id., but 27.v.2004.

Diagnosis.

Similar to Disophrys strigata Enderlein, 1920, from Indonesia (Sumatra) because of the completely yellow pterostigma, blackish labrum and presence of a ramellus. Disophrys strigata differs by having the hind leg completely black ( Disophrys maculifera has at least hind coxa, trochanter and trochantellus yellowish ventrally), fore coxa with a black patch, middle of mesopleuron and dorsal third of metapleuron and propodeum medially black (brownish-yellow in Disophrys maculifera ).

Description.

Holotype, ♀, length of body 9.8 mm, of fore wing 11.1 mm.

Head.

Antennal segments 55, length of third segment 1.3 times fourth segment, length of third, fourth and penultimate segments 1.9, 1.6 and 1.8 times their width, respectively; scapus robust; length of maxillary palp 0.6 times height of head; in dorsal view length of eye 1.5 times temple; temple rather bulging (Fig. 122); POL:OD:OOL = 7:6:20; face and clypeus shiny, densely setose with sparse fine punctures; frons and vertex smooth; pair of crests between antennal sockets sharp, lamelliform, extended to frons forming x-like shape; lateral carinae from anterior rim of lateral ocelli near to antennal sockets laterally (Fig. 122).

Mesosoma.

Length of mesosoma 1.7 times its height; subpronope small and shallow; side of pronotum smooth; area near lateral carina of mesoscutum crenulate; mesoscutum shiny and smooth; medio-posteriorly flat, middle lobe without a pair of distinct shallow grooves; lateral lobes flattened; notauli wide, deep and coarsely crenulate; scutellar sulcus with one carina and 0.8 times as long as dorsal face of scutellum; scutellum slightly convex, shiny and finely punctate, its subposterior crest long and transverse; precoxal sulcus wide and strongly crenulate; mesopleuron below precoxal sulcus narrowly and sparsely finely punctate and above precoxal sulcus shiny and smooth; metapleuron with strong rugae and long setae; propodeum with large areola, costulae, with short basal and long apical longitudinal carinae; propodeal spiracle round, 1.7 times as long as wide, distance between spiracle and lateral carina 1.5 times as long as width of spiracle.

Wings.

Fore wing: second submarginal cell narrowed anteriorly, with ramellus 0.8 times as long as vein r (Fig. 126); r:3-SR:SR1 = 8:9:75; 2-SR:3-SR:r-m = 13:9:13. Hind wing: M+CU 1.6 times as long as 1-M (30:19); surroundings of cu-a densely setose.

Legs.

Length of hind femur, tibia and basitarsus 3.4, 5.5 and 8.3 times their width, respectively; outer side of hind coxa smooth; hind femur (as remainder of legs) with long and dense setosity; outer side of apex of hind tibia with two equal long pegs; outer hind spur distinctly widened basally and curved apically; length of outer and inner spurs of middle tibia 0.4 and 0.5 times middle basitarsus, respectively; length of outer and inner spurs of hind tibia 0.3 and 0.5 times hind basitarsus, respectively.

Metasoma.

First tergite gradually widened apically (Fig. 125), shiny and smooth; length of first tergite 1.6 times its apical width, with three transverse rows of setae apically and slightly depressed laterally; second metasomal suture fine (Fig. 125); ovipositor sheath 0.3 times as long as inner hind tibial spur; ovipositor rather robust, widened basally and gradually curved.

Colour.

Brownish-yellow; antenna, apical third of fore wing, parastigma and vein C+SC+R dark brown; stemmaticum, lateral and middle lobes of mesoscutum anteriorly, mesosternum, metasoma and hind leg (but hind coxa, trochantellus and basal half of hind femur yellow); metasoma (but first tergite and first-third sternites yellow) black.

Variation.

Antennal segments 54-57; second submarginal cell of fore wing more or less narrowed anteriorly and with a short or rather long ramellus; vein M+CU of hind wing 1.6-1.8 times as long as 1-M; female and male may have hind leg and metasoma entirely black.

Distribution.

Central North Vietnam: Ha Tinh and S. Vietnam: Dong Nai.

Biology.

Unknown.

Etymology.

From “macula” (Latin for “spot”), and “fero” (Latin for “carry”), because of the black lobes of the mesoscutum.
