( Figure 1O ) Description Antennae in male bipectinate, tapered towards end, the longest ramus more than three times the diameter of flagellum. Frons yellow, probably faded from green. Labial palpus yellowish brown, probably faded from dark green, only slightly extending beyond frons. Vertex greenish-white. Dorsal side of thorax green. Hind tibia without hair-pencil. Wing pattern . Length of forewing „ 20–22 mm . Wings yellowish green. Outer margin of both wings smooth, no tail process on hindwing. Forewing with apex slightly falcate; antemedial line white, wavy, strongly curved outwards between lower margin of cell and vein A 2 . Postmedial line of both wings white, nearly straight, indistinct near costa. Submarginal line composed of white patches between veins. Discal spot invisible. Fringes green basally and white terminally. Underside greenish white, postmedial line visible. Male genitalia ( Figures 2O , 3O ). Uncus sclerotized, triangular. Socii sclerotized, curved and tapered. Gnathos developed, median area expanded, with a pair of short, pointed processes. Valva with basal half broad, tapered towards end. Spinose patch present, distally from which is a pointed harpe located on a transverse sclerotized ridge. Saccus developed, protruding, blunt. Transtilla undeveloped. Juxta membranous. Aedeagus sclerotized posteriorly and tapered. Sternite 3 without setal patches. Segment 8 ( Figure 5O ) with tergite sclerotized posteriorly, with posterior margin shallowly depressed at middle and expanded laterally; sternite deeply depressed at middle. Female genitalia . Unknown. Diagnosis Geometra burmensis is broadly similar externally to G. smaragdus , but much smaller, and the antemedial and postmedial lines of G. burmensis are not accompanied by shading as in G. smaragdus . In the male genitalia, G. burmensis is close to G. fragilis and G. sinoisaria , but the setae on the valvae are less developed than in those two species. The new species is distinctive in its gnathos, which is expanded in the middle and carries a pair of slender, curved processes: in G. sinoisaria the gnathos is a simple solid process, while in G. fragilis the gnathos carries a pair of thorn-like processes.
