Abstract


The white coconut scale, Parlagena bennetti Williams, 1969 (Hemiptera: Diaspididae) is reported for the fi rst time on New Zealand fl ax, Phormium tenax J.R. Forst. & G. Forst. (Xanthorrhoeaceae), coconut, Cocos nucifera L., Manila palm, Veitchia merrillii (Becc.) H.E. Moore, oil palm, Elaeis guineensis Jacq. and an oil palm hybrid OxG: E. oleifera x E. guineensis (Arecaceae) in continental Colombia, and on coconut from Venezuela. Previously, P. bennetti was known only on the Caribbean islands of Trinidad and San Andres, causing serious damage to coconut, its only known host until now. A brief characterization of P. bennetti and an updated list of 23 species of scale insects of the family Diaspididae reported worldwide on Elaeis spp. is provided.
