Notes on the pleasing lacewing genus Dilar Rambur, 1838 (Neuroptera, Dilaridae), with description of a new species from Vietnam.

In recent years many studies have been undertaken on the species of the genus Dilar Rambur, 1838 that occur in Asia, these have greatly increased the knowledge of Dilaridae in that region. Dilar has 69 valid species distributed in the Palaearctic and Oriental regions. In this paper we describe a new species Dilar aspoeckorum sp. nov. from Vietnam and a new female (probably Dilar harmandi (Navás, 1909)) from Nepal.

Description of adults and immature stages of Antipodoecia Mosely from Australia and synonymy of the families Antipodoeciidae and Anomalopsychidae (Insecta: Trichoptera).

The female, larva, and pupa of Antipodoecia Mosely from Australia are described, males re-examined and briefly described. Similarities with other trichopteran families are discussed. Based on morphological synapomorphies of males, females, pupae, and larvae, we infer that the genera Antipodoecia, Anomalopsyche, and Contulma share an immediate common ancestor, although relationships among these genera remain unresolved. Consequently, the Neotropical family Anomalopsychidae is a junior synonym of Antipodoeciidae from Australia.

The Trichoptera barcode initiative: a strategy for generating a species-level Tree of Life.

DNA barcoding was intended as a means to provide species-level identifications through associating DNA sequences from unknown specimens to those from curated reference specimens. Although barcodes were not designed for phylogenetics, they can be beneficial to the completion of the Tree of Life. The barcode database for Trichoptera is relatively comprehensive, with data from every family, approximately two-thirds of the genera, and one-third of the described species. Most Trichoptera, as with most of life's species, have never been subjected to any formal phylogenetic analysis. Here, we present a phylogeny with over 16 000 unique haplotypes as a working hypothesis that can be updated as our estimates improve. We suggest a strategy of implementing constrained tree searches, which allow larger datasets to dictate the backbone phylogeny, while the barcode data fill out the tips of the tree. We also discuss how this phylogeny could be used to focus taxonomic attention on ambiguous species boundaries and hidden biodiversity. We suggest that systematists continue to differentiate between 'Barcode Index Numbers' (BINs) and 'species' that have been formally described. Each has utility, but they are not synonyms. We highlight examples of integrative taxonomy, using both barcodes and morphology for species description.This article is part of the themed issue 'From DNA barcodes to biomes'.
