Variation
Paratypes (males; Fig. 4), antenna with 36–43 segments; first tergite 1.1–1.3 times as long as its apical width; medially second metasomal tergite 1.3–1.5 times as long as third tergite medially; body length 4.5–5.2 mm; fore wing length 3.6–4.4 mm.
Mesopleuron of males sometimes with fine transverse crenulae anteriorly; mesopleuron rugose-punctate anteriorly; fore and middle legs pale yellow; hind coxa and femur brown; hind tibia and tarsus yellowish brown; pterostigma and wing veins of males yellow or yellowish brown; first and second metasomal tergites white or ivory, except black spot at base of first and at apex of second tergite; third-fourth tergites black, except white basal corners; fifth and sixth tergites entirely white.
Distribution
NW Vietnam: Lai Chau (Tam Duong), Hoa Binh (Yen Thuy), Phu Tho (Xuan Son); NE Vietnam: Ha Giang (Vi Xuyen), Vinh Phuc (Tam Dao NP); NC Vietnam: Quang Binh (Phong Nha-Ke Bang NP).
Biology
Unknown.
Etymology
From “tri” (Latin for “three”), and “coloris” (Latin for “hue, tint”), because of the tricoloured body.
Notes
Iporhogas tricoloratus sp. n. differs from Iporhogas chinensis Chen & He, 1997, from China by having: the ocelli large; metapleuron finely punctate and vein M+CU of hind wing comparatively long, 1.4 times as long as vein 1-M. The new species differs from Iporhogas flavistigma Chen & He, 1997, from China by having the occipital carina in dorsal view roundly concave; metapleuron finely punctate and hind coxa finely punctate.
