Abstract
A new archaeococcoid (Hemiptera: Coccomorpha: Monophlebidae), Perissopneumon kalyaniense Das & Das sp. nov., is described from specimens collected on twigs of Glycosmis pentaphylla (Retz.) DC. (Rutaceae), a medicinal plant from Kalyani, West Bengal, India. The new species is similar to Perissopneumon ferox Newstead 1900, but can be distinguished by different character states of ventral multilocular pores and anal tube. An updated identification key to the species of Perissopneumon Newstead found worldwide is provided. The current status of the genus Perissopneumon Newstead is discussed.
