          Abstract

          Idiococcobius Hayat, syn. nov., is synonymised with Coccobius Ratzeburg, based on morphological and molecular data from a new species of Coccobius from Malaysian Borneo. The new species is sufficiently similar morphologically to the type species of Idiococcobius to place it unambiguously within that genus, but molecular data from the new species, and a reassessment of the morphology of Idiococcobius, indicate synonymy of the two genera. Idiococcobius encarsoides Hayat is therefore transferred to Coccobius; resulting in the new combination: Coccobius encarsoides (Hayat), comb. nov. Coccobius islandicus Geng & Polaszek, sp. nov, is described from morphology and DNA sequence data.

            DNA barcodes distinguish species of tropical Lepidoptera.

            Although central to much biological research, the identification of species is often difficult. The use of DNA barcodes, short DNA sequences from a standardized region of the genome, has recently been proposed as a tool to facilitate species identification and discovery. However, the effectiveness of DNA barcoding for identifying specimens in species-rich tropical biotas is unknown. Here we show that cytochrome c oxidase I DNA barcodes effectively discriminate among species in three Lepidoptera families from Area de Conservación Guanacaste in northwestern Costa Rica. We found that 97.9% of the 521 species recognized by prior taxonomic work possess distinctive cytochrome c oxidase I barcodes and that the few instances of interspecific sequence overlap involve very similar species. We also found two or more barcode clusters within each of 13 supposedly single species. Covariation between these clusters and morphological and/or ecological traits indicates overlooked species complexes. If these results are general, DNA barcoding will significantly aid species identification and discovery in tropical settings.
