Type material.
Holotype, ♀ (IEBR), Aga. 170, "S. Vietnam: Kien Giang, Phu Quoc N.P., 4.xii.2003, N.Th. Huong".
Diagnosis.
The colour pattern of this species seems to be unique in the genera Troticus and Disophrys , having the wings completely yellowish and having only a small isolated stigmal spot.
Description.
Holotype, ♀, length of body 16.0 mm, of fore wing 16.0 mm.
Head.
Antennal segments 68, length of third segment subequal to fourth segment, length of third, fourth and penultimate segments 1.8, 2.0 and 1.2 times their width, respectively; apical antennal segment long conical, 2.6 times as long as penultimate segment; length of maxillary palp 0.7 times height of head; in dorsal view length of eye 1.3 times temple; temple gradually narrowed (Fig. 394); ocelli large, POL:OD:OOL = 10:9:24; face with dense distinct fine punctures; lateral carina of frons near antennal sockets (Fig. 394); pair of crests between antennal sockets slightly convergent; frons, vertex and temple smooth, sparsely setose.
Mesosoma.
Length of mesosoma 1.5 times its height; subpronope very deep and large; pronotum smooth laterally, crenulate anteriorly; area near lateral carina of mesoscutum smooth; side of mesoscutum shiny and smooth, medio-posteriorly slightly depressed, middle lobe convex; notauli wide, deep and coarsely crenulate; scutellar sulcus short with 3 carinae and 0.4 times as long as dorsal part of scutellum (Fig. 396); scutellum distinctly narrowed with sharp distinct punctures, subposterior crest strong and slightly curved; mesopleuron below precoxal sulcus finely punctate and above sulcus shiny, almost smooth; precoxal sulcus complete, deep and strongly crenulate, with one crenula connected to prepectal carina (Fig. 395); metapleuron finely punctate; propodeum with pentagonal areola and medial carina basally; spiracle very large, subelliptical, 2.4 times as long as wide (Fig. 396), distance between spiracle and lateral carina 0.5 times as long as width of spiracle.
Wings.
Fore wing: second submarginal cell large, pentagonal, narrow anteriorly, without ramellus (Fig. 393); r:3-SR:SR1= 6:10:75; 2-SR:3-SR:r-m = 12:10:14. Hind wing: M+CU rather long, 0.8 times as long as 1-M (42:50); surroundings of cu-a densely setose.
Legs.
Hind coxa rather long, hind femur robust, length of hind femur, tibia and basitarsus 4.0, 7.2 and 12.6 times their width, respectively; hind femur (as remainder of legs) with long and dense setosity; outer side of apex of hind tibia with two equal and distal each other pegs; length of outer and inner spurs of middle tibia 0.3 and 0.4 times middle basitarsus, respectively; length of outer and inner spurs of hind tibia 0.3 and 0.4 times hind basitarsus; fore and middle tarsi slender.
Metasoma.
First tergite slender, smooth, slightly widened apically (Fig. 397); length of first tergite 1.5 times its apical width, slightly depressed laterally; second metasomal suture absent (Fig. 397), ovipositor sheath short conical, 0.2 times as long as inner hind tibial spur.
Colour.
Yellow; antenna brown but scapus yellow, blackish ventrally; fore wing with isolated stigmal spot.
Distribution.
S Vietnam: Kien Giang.
Biology.
Unknown.
Etymology.
From “allo” (Greek for “other”), and “flavus” (Latin for “yellow”), because of the different yellow colour pattern.
