A very variable species, especially in respect to its coloration. Melanistic males are similar to melanistic males of Euagathis forticarinata (Cameron), but the latter have the scutellum angulate anteriorly, the mesoscutum and the head dorsally never more or less darkened and the mesoscutum and mesopleuron distinctly sculptured. Variation in the series from South Vietnam: second submarginal cell of fore wing with or without a short ramellus; apical antennal segment 1.5-1.7 times as long as penultimate segment; vein M+CU of hind wing 0.5 times as long as 1-M; first tergite 1.8-2.0 times as long as its apical width; hind tibia dark brown or yellowish-brown apically. Distribution. S Vietnam: Dong Nai, Kon Tum. Outside Vietnam known from Brunei; Indonesia; (Java; Sumatra), Malaysia (Sabah) and Thailand. Figures 160-162.
