Diagnosis.  
 Troporhogas benjamini sp. nov. can be differentiated from others species by its colour pattern, which is mainly dark brownish red with ivory white on mouthparts including palps, tegula (Fig. 12 C) and TT 1 and 2 (anteriorly and laterally) and T 6. Metasoma bicoloured: T 1 and T 6 ivory, T 2 anteriorly and laterally ivory with black mark in the middle, TT 3–5 mainly black except for small anterolateral areas.   
Description.  
Holotype, female body length 5.5 mm; fore wing 4.9 mm; ovipositor sheath 0.05 mm.  
 Head. Antenna with 50 flagellomeres. Terminal flagellomere acuminate, 3.7 × longer than wide, 1.4 × longer than penultimate flagellomere. First flagellomere 1.2 × longer than second and third, respectively. Width of head: width of face: height of eye = 3.2: 1.5: 1.0. Inter-tentorial distance 3.2 × tentorio-ocular distance. Face and clypeus rugose with sparse setosity laterally. Frons with strong transverse striation that obscure the transverse carina arising from outer part of antennal sockets. Shortest distance between posterior ocelli: transverse diameter of posterior ocellus: shortest distance between posterior ocellus and eye = 1.0: 1.8: 1.8. Vertex and temple shiny and with sparse setosity, with mid-longitudinal groove. Occipital carina weakly curved dorsally.   
 Mesosoma. Mesosoma 2.0 × longer than high. Entire mesosoma coriaceous and setose. Mesopleuron and metapleuron setose. Mesoscutum shiny, without groove medially, sparsely punctate, notauli present. Scutellar sulcus smooth with strong medial carina and a pair of incomplete submedial carinae. Axillae narrow, finely striate. Raised anterodorsal area of mesopleuron below subalar depression with strong punctures tending to merge into distinct diagonal striate anteriorly. Precoxal sulcus complete, sinuate, transversely striate, broad and weakly impressed anteriorly becoming narrower and deeper to posterior margin of mesopleuron. Propodeum with submedial carinae anteriorly weakly curved and converging posteriorly; with strong setiferous punctures lateral to them, reticulate with long setae and without a mid-longitudinal carina.   
 Wings. Fore wing. Lengths of fore wing veins r-rs: 3 RSa: 3 RSb = 1.0: 2.7: 3.7. Lengths of vein 2 RS: 3 RSa: rs-m = 1.7: 2.0: 1.0.   
 Legs. Lengths of fore femur: fore tibia: fore tarsus = 1.1: 1.0: 1.1. Lengths of hind femur: hind tibia: hind tarsus = 1.0: 1.1: 1.4. Length of hind femur and tibia 2.7 × and 6.8 × as long as wide, respectively. Hind tibial spurs with long setae on basal 0.3. Tarsal claws with large acutely pointed basal lobe.   
 Metasoma. T 1 1.5 × longer than posteriorly wide. T 2 1.5 × as long as T 3. TT 1 and 2 with mid-longitudinal carina dorsally, sparsely striate. TT 3–6 with distinct striate sculpture. Ovipositor sheath straight and much shorter than hind basitarsus, ~ 0.2 × length hind femur (including trochantellus).   
 Colour. Bicoloured body; scapus, pedicellus and flagellar segments dark brown. Head brownish black, but mouthparts area ivory, stemmaticum dark brown. Mesosoma dark brown to black except for ivory tegulae. Metasoma bicoloured; T 1 and T 6 ivory, T 2 anteriorly and laterally ivory with black mark in the middle, TT 3–5 mainly black, hypopygium white. Wings hyaline with dark brown venation, pterostigma brown. Fore legs and mid legs bicoloured brownish and white, hind legs entirely black. Ovipositor and ovipositor sheath black.   
 Male. Length of body 5.9 mm, of fore wing 4.9. Antenna incomplete, with at least 38 flagellomeres. Sculpture on frons less strong. Occipital carina distinctly pointed medially. Head yellow, darker dorsally. Mesosoma orange-yellow except mesopleuron, mesosternum, metapleuron and propodeum which are largely brown to piceous. Metasoma cream-white except T 3 behind anterior transverse groove with pair or large black marks the join narrowly across midline and project to posterolateral margin, and T 4 which same pattern as T 3 except black marks not connected medially.
