Calyptomena

The genus name Calyptomena was introduced in 1822 by the American naturalist Thomas Horsfield.^[2] The name was also introduced in the same year by Stamford Raffles,^[3] but Horsfield's work was published in June 1822 and has priority over Raffles' article, which was published in November 1822.^[4] The genus name combines Ancient Greek kaluptos meaning "covered" with mēnē meaning "moon".^[5]

The genus contains three species.^[6]
