Pan-Pacific Entomologist. 79: 128-134 Interpretive Summary: Caterpillars of the moth family commonly known as leafrollers are economically important pests of a variety of crops. In Chile they are known to feed on citrus, grapes, kiwifruit, apples, and many others. In order to effectively detect and intercept these species on commodities imported into the United States, it is important to make available illustrations and descriptions of these and related pest species with which they may be confused. In this paper, we present diagnoses and illustrations of two Chilean species that each have numerous forms that may be misinterpreted as different species. This information will be useful to scientists interested in the leafroller fauna of Chile, for pest managers in Chile, and for U.S. action agencies such as APHIS, whose goal is to exclude invasive foreign species at U.S. ports-of-entry.
Technical Abstract: The genus Lypothora Razowski, 1981, was proposed for three species known only from the holotypes collected in Chile. We recognize two species, L. fernaldii (Butler) and L. walsinghamii (Butler); the third species, L. blanchardi (Butler), is considered a synonym of L. walsinghamii, new synonymy. Typical of many Neotropical Polyorthini, species of Lypothora are highly polymorphic. Specimens examined were associated with the two recognized species on the basis of uniformity in male and female genitalia and co-occurrence of males and females at single collecting localities on the same date. We present illustrations of the genitalia and facies.
