Cocytius, Amphonyx, Morcocytius, Pseudococytius The Cocytius genus has recently been divided into several new genera. The moths listed below were previously all considered Cocytius species. Cocytius antaeus Fw upperside semitransparent posterior to vein CuA1; black dash here consequently more or less obliterated; dash posterior to vein M3 heavier, buffish white subbasal line separated into costal, more distal disco-cellular, and posterior part, differing from Cocytius duponchel in that posterior part is more distal, at right-angles to cubital vein and more distal than costal part; the reverse is true in Cocytius duponchel; postdiscal line more curved than in Cocytius duponchel. Both wings undersides often with conspicuous ochre-yellow wash. Hindwing upperside with transparent spaces long, that posterior to vein M1 obviously longer than the brown wing border is broad; these spaces incised distally as the border is dentate between veins; a semitransparent patch that posterior to vein CuA2 anteriorly. Amphonyx duponchel Two thin dark streaks from upper thorax to mid thorax where they expand into teardrops. Forewing upperside with black discal dashes between veins M3 and CuA2 not prominent; discal spot transverse, kidney-shaped, dirty white. Hindwing upperside with translucent patch posterior to vein M1 shorter than the black marginal band is broad at vein M1 Amphonyx lucifer Thorax: black markings prominent against greyish green. Abdomen: mesial line usually prominent, sometimes faint or widely interrupted. Ground colour varies from walnut shell, yellowish-brown to greenish-grey. Two narrow, distinct dark streaks posterior to veins M3 and CuA1. Morcocytius mortuorum Dull orange band across upper abdomen at junction with thorax. Three small yellow-orange dots between each abdominal segment, Note strong presence of white scales in antemedial line. Forewings lack streaks or bars. Pseudococytius beelzebuth More orangey-brown shading on forewing than in other species in this group. Strong presence of black diagonal line from costa to cell. Line, interrupted by cell, continues as thicker, shorter black bar, parallel to inner margin. Black, much thinner streak often interrupted above bar.

Euryglottis Euryglottis albostigmata Distinct in colour and patterning from other Euryglottis species. Fw dorsal surface lacks white apical slash, lacks lower subterminal angle-shaped markings. Euryglottis aper The forewing dorsal surface has a well marked discal band of three lines. The ventral surface of the abdomen has apical dots on sternites 3-5, but these are indistinct as compared with those of Euryglottis guttiventris. Euryglottis davidianus Similar to Euryglottis aper, but easily distinguished by the head paler; yellow abdominal spots smaller; forewing upperside with antemedian and postmedian lines much straighter. Euryglottis dognini Abdomen: three rows of white spots on each side; middle row not yellow as in Euryglottis davidianus and Euryglottis aper. Abdomen ventral surface: large white patch at base. The tips of coxae are white. CATE Euryglottis guttiventris Abdomen underside with apical spots on sternites 3-5 distinct, more so than in Euryglottis aper; basal patch pale. Forewing upperside with discal band and vein-streaks less distinct than in Euryglottis aper.
