It includes all the available distributional data reviewed in the literature and additional records from material examined in private and public collections. All the provincial records are listed for each taxon. For some uncommon or little-known species, further details on their distributions are given. The current taxonomic arrangements of some species-groups are discussed. Furthermore, the female of Meroleuca (Meroleucoides) albomaculata (Dognin, 1916) is described for the first time and Molippa placida (Schaus, 1921) is reported for the first time for Peru.

  • Opinion Request No.2011-SA-0213
    ANSES Opinion Request no.2011-SA-0213 Maisons-Alfort, 16 August 2011 The Director Genera l OPINION of the French Agency for Food, Environmental and Occupational Health & Safety on the analysis of the risks to health and the environment related to strategies in French Guiana to combat the Hylesia metabus moth (Lepidoptera: Saturniidae), the agent responsible for “Caripito itch” dermatitis ANSES undertakes independent and pluralistic scientific expert assessments. ANSES primarily ensures environmental, occupational and food safety as well as assessing the potential health risks they may entail. It also contributes to the protection of the health and welfare of animals, the protection of plant health and the evaluation of the nutritional characteristics of food. It provides the competent authorities with the necessary information concerning these risks and the requisite expertise and technical support for drafting legislative and statutory provisions and implementing risk management strategies (Article L.1313-1 of the French Public Health Code). Its opinions are made public. On 8 August 2011, ANSES received an urgent request from the Ministries for the Environment, Health and Labour to analyse the risks to health and the environment of the different control strategies for Hylesia metabus in French Guiana. 1. BACKGROUND AND PRESENTATION OF THE ISSUE Since the end of May 2011, certain communities close to mangrove swamps in coastal areas of French Guiana have been infested by a nocturnal moth, Hylesia metabus, commonly known as the Yellowtail or Ashen Moth. An unusual feature of the female is the presence of microscopic urticating hairs on its abdomen that it releases into the air, which in humans cause persistent rashes and itching.

  • Taxonomy, Phylogeny and Resource Use of Glyptapanteles (Hymenoptera: Braconidae, Microgastrinae), Genus Highly Diversified in the Neotropics
    TAXONOMY, PHYLOGENY AND RESOURCE USE OF GLYPTAPANTELES (HYMENOPTERA: BRACONIDAE, MICROGASTRINAE), GENUS HIGHLY DIVERSIFIED IN THE NEOTROPICS BY DIANA CAROLINA ARIAS PENNA DISSERTATION Submitted in partial fulfillment of the requirements for the degree of Doctor of Philosophy in Entomology in the Graduate College of the University of Illinois at Urbana-Champaign, 2014 Urbana, Illinois Doctoral Committee: Professor James B. Whitfield, Chair, Director of Research Professor May R. Berenbaum Professor Sydney A. Cameron Dr. Marianne Alleyne Dr. Kevin P. Johnson ABSTRACT Among hymenopteran parasitoid wasps, Ichneumonoidea is one of the superfamilies with the highest number of species and includes the highly diverse Microgastrinae subfamily. Microgastrinae wasps are very abundant and can be collected in many different terrestrial habitats. A considerable number of species have been used in successful biological pest control programs, making it one of the most important insect groups. Glyptapanteles is one of the larger genera within Microgastrinae, which was segregated after several attempts to subdivide the gigantic genus Apanteles Foerster 1862. To date, 122 species have been described worldwide, of which only six are Neotropical, despite unpublished evidence that this genus is one of the largest in the Neotropics. Glyptapanteles are diminutive parasitoid wasps, which are free-living as adults, but as immatures, they attack exclusively larvae of Lepidoptera as a food resource for their developing larvae. These parasitoid wasps play a preponderant role in regulating their lepidopteran host populations and in maintaining high biological diversity in terrestrial ecosystems. A reliable revision for the Neotropics has not yet been attempted and many Glyptapanteles species remain undescribed. The scarcity of both taxon sampling and biological information is no longer standard for some Neotropical groups of insects.
