( Figs. 5, 10, 15 , 48–54 ) Green to yellow green ( Figs. 5, 10 ), 4 longitudinal pale yellow lines on vertex and pronotum, 3 on scutellum. Vertex margin anteriorly with transverse submarginal ventral fuscous line. Compound eyes blue, ocelli off white in color. Forewings green with apical 1/3 brown, white spots in apical and anteapical cells; brown spot at end of clavus; usually 3 additional brown spots on apical margin, veins R and R1 red. Head including eyes 1.2x as long as width of pronotum. Head not produced in front, crown length 0.6x shorter than width between eyes. Face 0.9x as long as wide. Frontoclypeus longer than wide; frontal suture, terminating laterad of ocelli. Ocelli near anterior margin, very closely oppressed to eyes. Pronotum length 0.5x as long as wide and 1.3x length of scutellum. Male genitalia. Pygofer ( Fig. 48 ) longer than wide, posterior margin oblique, with posterior ½ heavily setose. Valve subtriangular. Style ( Fig. 50 ) with bluntly angulate preapical lobe, apophysis short, beak-like, 0.16 of total length. Connective ( Fig. 54 ) with stem 1.2x shorter than arms.Aedeagal shaft in lateral view slender, slightly sinuate near midlength, apically membranous, with pair of long, slender asymmetrical subapical procesess, one recurved and other nearly straight, gonopore subapical on ventral margin basad of process ( Figs. 51–53 ).

Holotype ³, INDIA : Meghalaya : Barapani , Umiam District , ( 25°39’36.2”N 91°54’03.6”E ), 14.xii.2017 , Sweep net Coll. Stuti ( NPC ). Etymology. The species name alludes to the asymmetrical subapical processes of the aedeagus Remarks. Thomsonia asymmetrica sp. nov. externally resembles T. gressitti (Distant) and T. porrecta (Walker) . The new species differs in having the aedeagal shaft sinuate medially with two asymmetrical subapical processes, one recurved and the other straight, compared to T. gressitti (Distant) which has pairs of apical and preapical processes. The new species differs in having asymmetrical apical processes of the aedeagus and the shaft sinuate in lateral view, compared with T. porrecta (walker) which has symmetrical apical processes of the aedeagus and the shaft straight in lateral view..
