Book Description
Abstract: The phylogenetics, systematics, taxonomy, and biology of Gelechioidea (Insecta: Lepidoptera) are investigated. This superfamily is probably the second largest in all of Lepidoptera, and it remains one of the least well known. Taxonomy of Gelechioidea has been unstable historically. In Chapters Two and Three, I review the taxonomy of Gelechioidea and characters that have been important. Chapter Four provides the first phylogenetic analysis of Gelechioidea to include molecular data. I combine novel DNA sequence data from Cytochrome oxidase I and II with morphological matrices for exemplar species. The results challenge current concepts of Gelechioidea, suggesting that traditional morphological characters may not be homologous structures and are in need of further investigation. I conduct in Chapter Five an in-depth study of morphological evolution, host-plant selection, and geographical distribution of a medium-sized genus Depressaria Haworth (Depressariinae), larvae of which generally feed on plants in the families Asteraceae and Apiaceae. Host-plant use is commonly studied in this group because of physiological and behavioral responses exhibited by Depressaria pastinacella to furanocoumarins produced by their host plants, yet no species level phylogeny is available. This study is the only modern phylogeny of the genus, and includes all North American species but one, and about half the Old World species. In Chapter Six I describe nine new species of Scythris Hübner (Scythridinae) from the Galápagos Islands, Ecuador, and provide a key and illustration of genitalia and abdominal modifications. Finally, Chapter Seven represents an application of moth taxonomy to address questions of sampling protocols used for studies of biodiversity and conservation. I use Gelechioidea in eastern North America as indicators of diversity, with attention to the effectiveness of different sampling protocols with respect to active versus passive sampling, and plot-based versus plotless sampling. A list of Gelechioidea was produced from trap sites from an Appalachian forest in southern Ohio. The composition and diversity of Ohio Gelechioidea captured in a passive, plot-based protocol compares favorably to more exhaustive sampling, and reinforces recent (and counterintuitive) recommendations that it is more efficient and repeatable to focus surveys on target groups in focal localities rather than to conduct extensive sampling programs.

Book Description
This work provides a hypothesis of evolutionary relationships within the Neotropical genus Sparganothina and between this genus and other lineages of Sparganothini (Lepidoptera: Tortricidae). Nineteen species are considered to belong to Sparganothina. Ten additional species are placed in "Sparganothina" and five in "Coelostathma" pending a better phylogenetic understanding of Coelostathma and related genera. Thirty species are described as new.

Book Description
This Special Issue on the Systematics and Phylogeny of Weevils presents 31 new research papers on one of the most diverse and successful groups of animals on Earth, the beetle superfamily Curculionoidea. It was in part inspired to commemorate the extraordinary life and scientific achievements of Guillermo (“Willy”) Kuschel (1918–2017), who shaped this field of science over the last century like no other weevil systematist. The papers in this memorial issue span weevil faunas from all over the globe, including South and Central America, Africa, Europe and the Near East, South-East Asia, New Guinea, Australia and New Zealand. They include major advances on the phylogeny and classification of the “broad-nosed” weevils (Entiminae), on the weevils associated with American cycads and on the unique extinct weevil fauna preserved in the 100-million-year-old Burmese amber, when weevils started to diversify alongside the oldest angiosperm plants. They comprise a tribute to Willy Kuschel, the proceedings of a weevil symposium held in his honor in 2016 in Orlando, Florida, 24 systematic studies (including seven phylogenetic analyses) and five other contributions on the diversity, biology, distribution, evolution and fossil history of weevils. In the papers collated in this volume, 30 new genera and 92 new species of weevils are described and a new family of extinct weevils is recognized.

Book Description
The authors examine relationships within the Chrysoxena group of the tortricid tribe Euliini. They define 54 species among six genera: Chrysoxena Meyrick; Vulpoxena Brown, new genus; Thoridia Brown, new genus; Dorithia Powell; Cuproxena Powell and Brown, new genus; and Bidorpitia Brown, new genus. Using cladistic methods, the authors develop a phylogenetic hypothesis for the genera and species groups of Dorithia and Cuproxena. A systematic treatment of the included species provides appropriate generic assignment for several previously misplaced species and describes many taxa as new.
