Inventario de himenópteros parasitoides (Cynipoidea y Chalcidoidea,. Hymenoptera, Insecta) de la isla de Coiba (Panamá)

Abstract

Inventory of Parasitic Hymenoptera (Cynipoidea and Chalcidoidea Hymenoptera, Insecta). A preliminary list is provided concerning an inventory of parasitic Hymenoptera fauna from Coiba island (Panama). The selected inventoried families were: Figitidae (Cynipoidea) and Chalcidoidea, Encyrtidae and Eucharitidae (Chalcidoidea). The work represent the rust relevant collecting and published data of that hyrnenopteran families from Coiba and from continental Panama. Three collecting trips (two-five weeks long) were made to Coiba island between 1994 and 1996 and twenty nine collecting sites, representing most Coiba ecosystems and hymenopteran habitats were samp1ed. Insects were collected mainly by means of sweep net and Malaise traps. Cynipoidea.- An amount of 1602 individuals of Cynipoidea was collected. Taxa identified can be surnmarised as follows: "Figitinae": two unidentified species of Neralsia Cameron; Aspicerinae: two species of Prosaspicera Kieffer and Balna nigriceps Cameron, 1883. The later is redescribed and illustrated with electronscan photographs. The following Eucoilinae genera are listed, mostly representing the first record for Panama: Dieucoila Ashmead, Eucoila Westwood, Ganaspis Ftirster, Hexacola Ftirster, Kleidotoma Westwood, Nordlandiel/a Diaz, Odonteucoila Ashmead, Rhabdeucoela Kieffer, Rhoptromeris Ftirster, Tropideucoila Ashmead and Trybliographa Ftirster. Chalcidoidea.- Four genera of Chalcididae are recorded: Brachymeria Westwood, Conura Spinola, Haltichella Spinola and Notaspidium Dalla Torre, 1897. A preliminary identification 1ist of Conura species is presented: thirty-four species are listed, thirteen of them representing new species. A list of thirty-one genera of Encyrtidae is presented: Acerophagoides Blanchard, Acerophagus Smith, Adelencyrtus Ashmead, Aenasius Walker, Anagyrus Howard, Anicetus Howard, Apoanagyrus Compere, Apsilophrys De Santis, Archinus Howard, Arhenophagus Aurivillius, Blepyrus Howard, Cerchysiella Girault, Cheiloneurus Watwood, Chrysoplatycerus Ashmead, Encyrtus Latreille, Forcipestricis Burks, Gyranusoidea Compere, Helegonatopus Perkins, Hexacladia Ashmead, Lamennaisia Girault, Leptomastix Ftirster, Mahencyrtus Masi, Meniscocephalus, Metaphycus Mercet, Oencyrtus Ashmead, Prionomastix Mayr, Psyllaephagus Ashmead, Zaomma Ashmead and Zaommoencyrtus Girault. Four genera, representing at least nine species of Eucharitidae, two of them probably new for science, are recorded: Orasema Cameron, Dilocantha Shipp, Kapala Cameron, Obeza Heraty and Pseudochalcura Ashmead. Taxonomic list from the faunistic surveys in Coiba is discussed and compared with available data from Pan ama and Costa Rica in order to estimate the global richness of the studied groups in the island. A rough estimation of global fauna of Hymenoptera in Coiba, from the data of the selected groups of parasitic Hymenoptera, is also made, and numbers are compared with available data from other islands.
