Abstract
A new species of Dactylopius Costa (Dactylopius gracilipilus Van Dam & May) is described and illustrated. It is morpho-logically similar to Dactylopius tomentosus (Lamarck), but has more gracile truncate setae, abundant simple pores dorsally, and appears to be host-restricted to Corynopuntia Knuth (Cactaceae: Opuntioidea).References
