| description | <p>The monophyly of the Geometrinae is examined by investigating the green wing pigment and morphology of the tympanal (hearing) organs. The green colour of Geometrinae is caused by a single pigment, here termed geoverdin, located in the scales. Analysis of this pigment indicates that it is neither a bile pigment nor a derivative of chlorophyll. A method developed for taxonomic comparison of lepidopteran pigments and based on a chromatographic profiling technique is presented. The morphology of geometrid tympanal organs is described and an apomorphy for the Geometrinae, the distinctive shape of the ansa, is proposed. The value of the taxonomic literature on the Geometrinae is assessed in terms of its ability to identify internal monophyletic groups.</p> <p>A taxonomic revision of the genus <em>Oospila</em> Warren is presented, in which the neotropical genera <em>Auophylla</em> Warren, <em>Auophyllodes</em> Prout, <em>Halioscia</em> Warren, <em>Oospila</em> Warren, <em>Oospiloma</em> Prout, <em>Progonodes</em> Warren and <em>Racheolopha</em> Warren are united into a single genus. Phylogenetic analysis is used to demonstrate the monophyly of the revised genus <em>Oospila</em> and to assess relationships between species groups within it. The revised genus <em>Oospila</em> is defined as a monophyletic group supported by two apomorphic characters: the form of the abdominal crests and the presence of an anellar complex produced by the fusion of the juxta and transtilla. Sixty-six species of <em>Oospila</em> are treated, of which three are described as new. One new subspecies is also described. Forty-eight species group names are synonymised, and 16 species are recombined with <em>Oospila</em>.</p> |
