Theretra lifuensis
Similar to Theretra celata celata but immediately distinguishable by the pink tone of the medial band of the hindwing upperside. Forewing less elongated than in Theretra celata celata and outer margin more convex between M1 and M3. Forewing upperside similar to Theretra celata celata but: ground colour darker and more grey; discal spot clearly evident; a scalloped olive-green band present distal to fourth postmedial line (barely indicated in some Theretra celata celata and absent in most). Hindwing upperside with pale medial band distinctly tinged pink, especially in females. Male FWL: 33.8-37.3 mm (n = 9). Female FWL: 40.1 mm (n = 1).
Male genitalia: Similar to Theretra celata celata but: Tegumen with a clear convex bulge on the dorsal margin just basal to uncus. Uncus narrower in lateral view; in dorsal view, lateral margins medially concave. Gnathos narrower in lateral view, posterior ventral surface less concave. Valve ovate with rounded distal margin; sacculus narrower. Harpe smaller with a distinctive three-pointed apex.
