Lam"; 2 ♀ (IEBR), Aga. 206 & 212, "Central North Vietnam: Nghe An, Pu Mat N.P., 8.ix.2005, P.Th. Nhi"; 2 ♀ (RMNH), Aga. 206 & 213, id.; 1 ♀ (IEBR), Aga. 182, id., but 22-25.vii.2006, Tr.X. Lam.
Diagnosis.
Similar to Disophrys subfasciata ( Brullé, 1846) from India, but that species has no horn-like protuberances between the antennal sockets (present in Disophrys rhinoides ), the face, mesoscutum and scutellum coarsely punctate (finely punctate), the scutellar sulcus with 3 carinae (with 1 carina), the area below the precoxal sulcus densely punctate (sparsely punctate) and the inner hind tibial spur 0.6 times (0.5 times) as long as the hind basitarsus.
Description.
Holotype, ♀, length of body 8.2 mm, of fore wing 7.5 mm.
Head.
Antennal segments 52, length of third segment 1.8 times fourth segment, length of third, fourth and penultimate segments 2.5, 1.4 and 2.0 times their width, respectively; apical antennal segment twice times as long as penultimate; length of maxillary palp 0.6 times height of head; in dorsal view length of eye 2.3 times temple (Fig. 136); POL:OD:OOL = 8:5:18; face finely punctate laterally, but rugose-punctate medially; crests between antennal sockets forming pair of large horn-like protuberances (Fig. 136); frons wide, shiny, with rugae; long carina emitted from each base of horn-like protuberances and diverging posteriorly; lateral carinae from anterior rim of lateral ocelli to antennal sockets laterally; vertex with sparse fine punctures.
Mesosoma.
Length of mesosoma 1.4 times its height; subpronope large and deep; side of pronotum with sparse fine punctures; area near sharp lateral carina of mesoscutum smooth; mesoscutum shiny and smooth with sparse fine punctures; medio-posteriorly impressed, its middle lobe with a pair of faint shallow longitudinal grooves; notauli narrow, deep and finely crenulate (Fig. 138); scutellar sulcus as long as dorsal face of scutellum; scutellum laterally smooth, slightly narrowed posteriorly, convex anteriorly and depressed posteriorly; subposterior crest transverse, lateral carina incomplete; precoxal sulcus wide and strongly crenulate; mesopleuron below and above precoxal sulcus shiny, with sparse fine punctures, almost smooth; metapleuron short setose and with sparse strong rugae; propodeum with strong lateral carinae, large areola with one transverse carina; propodeal spiracle elongate, elliptical, 2.8 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 without ramellus (Fig. 141); r:3-SR:SR1 = 8:10:78; 2-SR:3-SR:r-m = 12:10:13. Hind wing: M+CU 1.3 times as long as 1-M (25: 20); surroundings of cu-a densely setose.
Legs.
Length of hind femur, tibia and basitarsus 3.3, 6.1 and 7.8 times their width, respectively; outer side of hind coxa smooth; hind femur (as remainder of leg) with short and dense setosity; length of outer and inner spurs of middle tibia 0.5 and 0.6 times middle basitarsus, respectively; outer side of apex of hind tibia with two 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 robust; hind basitarsus with a distinct carina-like row of short setae ventrally.
Metasoma.
First tergite smooth and gradually widened apically (Fig. 140); length of first tergite 1.7 times its apical width, without setae apically; laterope long; second metasomal suture absent, ovipositor sheath robust and as long as basal width of hind tibia; ovipositor slender, slightly curved.
Colour.
Brownish-yellow; antenna and apical 0.6 of both wings dark brown; hind tarsal segments brown; stigmal spot large and dark brown (Fig. 141); basal two thirds of pterostigma, narrow area below pterostigma and basal 0.4 of wings yellow.
Variation.
Antennal segments 52-54; length of body 7.5-9.0 mm and of fore wing 7.5-8.6 mm; vein M+CU of hind wing 1.2-1.5 times as long as 1-M; one female has the body dusty dark brown.
Distribution.
NE Vietnam: Thai Nguyen, Hoa Binh and Central North Vietnam: Nghe An.
Biology.
Unknown.
Etymology.
From “rhinos” (Greek for “nose”), because of the small nose-like projections between the antennal sockets.
