Head. Antenna broken, with 51 segments remaining; middle segments twice longer than wide (6:3); third antennal segment 1.3 times fourth segment (9:7); width of face 1.1 times length of face and clypeus combined (19:17); malar space 0.85 times as long as mandible width (6:7); mandible width 0.9 times as long as hypoclypeal depression (7:8); in dorsal view height of eye 2.8 times as long as temple (17:6); occipital carina deeply concave (Fig. 11); in lateral view width of eye 3.0 times as long as temple (15:5); POL:Od:OOL=3:4:4; distance between anterior and posterior ocelli equal to OOL (Fig. 11); face with short median carina, rugose medially, lateral area with fine transverse striae; frons with fine transverse striae; vertex and temple smooth.
Mesosoma. Length of mesosoma 1.6 times as long as high (72:45); propleuron wide, crenulated (Fig. 13); notauli deep, crenulate; mesonotum with sparse fine punctures; scutellar sulcus 0.5 times as long as scutellum (6:12) with one medial carina; scutellum sparsely punctate; mesopleuron shiny and smooth medially, sparsely and finely punctate anteriorly and posteriorly; precoxal sulcus wide, crenulate (Fig. 15); mesosternum sparsely punctate; metapleuron rugose-punctate; propodeum areolate medially, rugose-punctate anteriorly, rugose latero-posteriorly (Fig. 12).

Fore wing: pterostigma 4.4 times as long as wide (44:10); r:2-SR:3-SR:SR1=10:13:26:42; vein r arising before middle of pterostigma; vein 1-SR+M nearly straight; vein cu-a distinctly postfurcal; 1-CU1:cu-a:2-CU1=3:6:28; basal length of second submarginal 2.5 times as long as its apical width (35:14). Hind wing: vein M+CU 1.3 times vein; M+CU:1-M:1r-m=32:24:12; vein 2-SC+R transverse.
Legs. Hind coxa sparsely punctate dorsally; length of hind femur, tibia and basitarsus 5.7, 8.75 and 9.0 times as long as their width, respectively; inner hind tibial spur 0.33 times as long as basitarsus (12:36); hind tarsal claw with large acute lobe (Fig. 16).
Metasoma. First tergite 1.2 times as long as its apical width (40:33) (Fig. 14); first-second tergites sparsely striate; medial length of second tergite 1.5 times third tergite (30:20); first-second metasomal tergites with medial longitudinal carina, sparsely striate (Fig. 14); third tergite without medial carina; third-fifth tergites densely striate; ovipositor sheath as long as hind inner spur; ovipositor slender.
Colour. Scapus and antennal segments brown; palpi yellow; stemmaticum black; pronotum and mesonotum yellow; mesopleuron, metapleuron and propodeum black; fore coxa ivory; fore femur, tibia and tarsus yellow, except telotarsus brownish yellow; middle coxa brown, fore femur, tibia and tarsus yellow, except telotarsus brownish yellow; hind coxa black, hind femur, tibia and tarsus blackish brown; fore wing yellowish brown; pterostigma yellow with brown border; veins yellowish brown; first and second tergites white, except black spot at apex of second tergite; third-fifth tergites black; tergite 6 white; hypopygium ivory with long sparse setae; ovipositor sheath brown.
Variation
Paratypes: antenna with 49 segments; first tergite 1.2 times as long as its apical width; medial length of metasomal second tergite 1.3–1.5 times third tergite medially; body length 6.1–7.8 mm; fore wing length 5.5–6.6 mm; stemmaticum brown; lateral lobes of mesoscutum dark brown; first metasomal tergite with brown spot at base.
Male
Unknown.
Distribution
NW Vietnam: Hoa Binh (Mai Chau), Lai Chau (Tam Duong); NC Vietnam: Ha Tinh (Huong Son).
Biology
Unknown.
Etymology
From “contra” (Latin for “opposite”), because of the contrasting orange and black of its body colour.
Notes
Iporhogas contrastus sp. n. differs from Iporhogas chinensis Chen & He, 1997, from China by having: the metapleuron rugose-punctate; precoxal sulcus wide, crenulate; hind tarsal claw with large lobe; vein cu-a of fore wing distinctly postfurcal; vein M+CU of hind wing 1.3 times as long as vein 1-M and hind leg entirely black. The new species differs from Iporhogas flavistigma Chen & He, 1997, from China by having: the occipital carina in dorsal view deeply concave; precoxal sulcus wide, crenulate; metapleuron largely punctate; vein 2-SC+R of hind wing transverse and hind leg entirely black.
