About Acosmeryx pseudonaga Butler, 1881
Color varieties of this species were repeatedly described as separate species, but they are now classified as color morphs of the single species A. shervillii. According to G. F. Hampson's The Fauna of British India, Including Ceylon and Burma: Moths Volume I, the adult moth has the following appearance: The body is greyish brown, with a dark vertex on the head. The prothorax, mesothorax, and metathorax each have a dark transverse streak. Each segment of the abdomen has dark, dorso-lateral oblique stripes. The fore wing has nine curved, waved dark antemedial lines. The interspaces between three of the pairs of lines are filled with dark brown, forming one subbasal band and two antemedial bands. There is a pale speck with a dark ring at the end of the cell; the pale center of this speck is sometimes absent. There are four curved postmedial lines on the fore wing, plus an oblique dark band that runs from beyond the middle of the costa to the outer angle. In some forms, this band extends outward along vein 5, making it more oblique. A pale, obsolescent submarginal line runs from below the apex to the outer angle, and sometimes extends out to the margin at vein 4. The hind wing is brownish fuscous, with faint traces of a pale patch and dark lines near the anal angle. The underside is more or less suffused with ferruginous, ochreous, and grey; the outer margin of both wings is dark, and the hind wing has five indistinct lines. The larva is green, with a series of brown dorsal spots and lateral oblique stripes on the 5th to 10th somites. It has an ocellated spot on the 4th somite, and a black stripe running from the 1st to 4th somite, with a yellow line above this black stripe. The larval horn is brown.
