| description | In 2003, a new gall-inducing wasp of the genus <i>Ophelimus</i> was detected in the Valparaíso Region (Chile), affecting tree plantations of <i>Eucalyptus globulus Labill</i> and <i>Eucalyptus camaldulensis</i> Dehnh. <i>Since then Ophelimus</i> has been frequently detected in different plantations in Chile, covering a widespread area. A preliminary collaborative study suggests that the micro-wasp detected should be classified as a new <i>Ophelimus</i> species. In this paper, using an integrative approach (including genetic, morphological, and behavioral data), we addressed the delimitation and description of this new species. This study involved the use of brood adult specimens, raised at the laboratory of <i>MIP</i>lagas Ltda., from infested twigs of <i>E. globulus</i> collected in several localities between of Valparaíso and Los Lagos Regions (Chile). Morphological structures were described according to current Eulophidae taxonomic keys, as well as additional traits, such as gall morphology and behavior. Genetic characterization was implemented using a phylogenetic approach, based on a 648 bp specific fragment of the mitochondrial Cytochrome Oxidase I gene (<i>COI 5</i> region) obtained from collected specimens and available databases (Genbank, NCBI, and BOLDSystem). Specifically, distinctive patterns of variation were detected in traits like gall and antennae morphology, growth habit trends, and a notorious polyphenism in the setae from the sub marginal vein. Overall evidence suggests that this new entity should be considered a new species in <i>Ophelimus</i>, which is henceforth named <i>Ophelimus migdanorum</i> Molina-Mercader. |
