This paper (originally published as 12.141) described the root borer, Acanthophorus rugiceps Gahan (Coleoptera: Cerambycidae), as a new record on physic nut, Jatropha curcas L. (Malpighiales: Euphorbiaceae), in India. The species involved has since been identified as Acanthophorus serraticornis (Olivier) by Dr. Alain Drumont (Entomology Department, Institut Royal des Sciences naturelles de Belgique, Bruxelles Belgium), which is known to be present in India. The original paper has therefore been withdrawn.
