Remarks

• Structure: Bremner (1907) described the female scale: "It has much the appearance of a clam, ranging in form from mytiliform to round, 1-1.5 mm in size, dirty-white in colour; the exuvia is at one side, and at the anterior extremity is glossy straw-coloured; the ventral scale is nearly as well developed as the dorsal, and has what appears to be the ventral half of the exuvia at the anterior end". Ferris (1938a) described the scale cover: "Female scale brown, broadly oval, exuviae apical. Scale of the male not seen".
• Biology: Occurring beneath the sheathing bases of leaves and among scales on the rootstocks.
• General Remarks: Description and illustration of adult female by Ferris (1920b, 1938a) McKenzie (1956), Ben-Dov (1988b) and by Gill (1997).
