5336CD28962AFF96FF7332EE5DA95382.taxon	description	Description. Male (Figs. 1 a – b): Head, thorax, and abdomen brown with a greyish overtone; head and thorax with light brown, antennae filiform, brownish yellow, apically hooked. Labial palpus protruding, brown greyish. Abdomen terminating in a black and a fan shaped tuft, close in shape to a gingko leaf (Fig. 7 a). FWL: 39 - 42 mm. FW elongate, with falcate apex, outer margin slightly excavated below the apex but then convex to the tornus, tornus clearly protruding. Upperside ground colour brownish, with a line from the costa towards middle of outer margin, thereby dividing a light brown apical area from the dark brown discal area, and a large dark green hook medially, which projects markedly outwards between veins M 3 to CuA 1. A wide, deep brown stripe present near the hooked patch. Underside of both wings predominantly light-brown, with two distinct dark brown median lines. A deep brown submarginal line separates the lighter marginal area from the darker rest of the wing. HW upperside blackish brown, with a light patch at tornus. Underside light brown with two distinct dark brown median lines. Submarginal line separating the darker marginal area from the lighter rest of the wing. Female (Figs. 1 c – d): FWL: 45 mm. Similar to the male, but with wings broader and the ground color is slightly paler. Abdomen ending in a point with only a few black hair-like scales. Male genitalia (Figs. 2 a – c): Uncus and gnathos form a typical macroglossine “ bird-beak ” structure. Uncus slightly curved, with a tiny apical hook, densely hairy dorsally. Gnathos markedly curved upward and much deeper than uncus, apex blunt. Valva rounded, with wider terminal part wider than the basal part, apex blunt. Sacculus almost straight, constricted apically into a short harpe, which is narrow and blunt. Phallus long and slender, with a distal transverse process; anterior lobe markedly wider than posterior one, with long spinules along two sides.	en	Jiang, Zhuo-Heng, Wang, Cheng-Bin (2020): Review of the genus Eurypteryx C.

5336CD28962AFF96FF7332EE5DA95382.taxon	diagnosis	Differential diagnosis. Eurypteryx bhaga is most similar to E. obtruncata Rothschild & Jordan, 1903, which is only known from the island of Sulawesi, Indonesia. The line on the forewing upperside from the costa towards middle of outer margin, which divides the light brown apical area from the dark brown discal area in E. bhaga, is more complete than in E. obtruncata. The hindwing upperside in E. bhaga is deep brown, with a light straight patch at tornus, but is slightly curved in E. obtruncata.	en	Jiang, Zhuo-Heng, Wang, Cheng-Bin (2020): Review of the genus Eurypteryx C.

5336CD289628FF90FF7331C65D15544B.taxon	description	Description. Male (Figs. 3 a – b): Head, thorax, and abdomen brown with a greyish overtone; head and thorax light brown; antennae filiform, brownish yellow, apically hooked. Labial palpus protruding, greyish. Abdomen ending in a triangular tuft (Fig. 7 b). FWL: 31 mm. FW elongate, apex sharply pointed, outer margin oblique, slightly excavated just below the apex and above the tornus, the latter clearly protruding outwards. Upperside ground colour brownish yellow, with greyish semicircular marginal area between the apex and vein M 3. Underside of both wings predominantly greyish-brown, with a straight greyish submarginal line separating the lighter marginal area from the darker rest of the wing. A round yellowish discal spot near the base of M 3. HW upperside dark brownish. Underside greyish-brown with a light grey postmedial line. Female (Figs. 3 c – d): FWL: 32 mm. Similar to male, but the round yellowish discal spot is visible on the forewing upperside and the submarginal line on the underside is dark brown. Abdomen ending in a narrow, brushshaped tuft. Male genitalia (Figs. 4 a – c): Uncus and gnathos form a typical macroglossine “ bird-beak ” structure. Uncus thin and slightly curved, with a tiny apical hook, sparsely hairy dorsally. Gnathos straight and only slightly thicker than uncus, apex blunt. Valva rounded, with basal part wider than terminal part, apex slightly blunt. Sacculus slightly constricted and markedly curved upward apically into a harpe. Phallus long and slightly curved, with a transverse process distally; anterior lobe of the process longer than the posterior, formed into a slender hook with spinules on two sides.	en	Jiang, Zhuo-Heng, Wang, Cheng-Bin (2020): Review of the genus Eurypteryx C.

5336CD289628FF90FF7331C65D15544B.taxon	diagnosis	Differential diagnosis. Eurypteryx dianae is most similar to the Thai species, E. geoffreyi Cadiou & Kitching, 1990 (Figs. 5 a – d). Both species have similar habitus characters, such as the brownish ground colour and yellowish discal spots on the forewings and hindwings. However, they can be separated by the different forewing shape, which is more elongated, the apex more pointed and the tornus more obviously protruding outwards in the male of E. dianae than in E. geoffreyi. The postmedial line on the undersides of the wings is totally missing in E. geoffreyi, but clearly visible in E. dianae. The ground colour of E. dianae is lighter compared with the brownish black of E. geoffreyi. The yellow discal spot of the female E. dianae is rather rounded compared to the half-moon-shape of E. geoffreyi. The male of E. geoffreyi also has a visible yellow discal spot on hindwing underside that is almost missing in the male of E. dianae. The apical abdominal tuft of the male E. geoffreyi (Fig. 7 c) and male E. bhaga (Fig. 7 a) appear more rounded than in E. dianae (Fig. 7 b). The sacculus (Fig. 4 b) of E. dianae is similar to E. geoffreyi, but lacks a semicircular tooth on the dorsal edge of the harpe, which is conspicuous in E. geoffreyi (Fig. 6 b). The phallus (Fig. 4 c) of E. dianae is longer and straighter than in E. geoffreyi and the transverse apical process has marginal spinules on two sides, whereas it is almost smooth in latter species (Fig. 6 c).	en	Jiang, Zhuo-Heng, Wang, Cheng-Bin (2020): Review of the genus Eurypteryx C.
