Cryptic species are organisms which look identical, but which represent distinct evolutionary lineages. They are an emerging trend in organismal biology across all groups, from flatworms, insects, amphibians, primates, to vascular plants. This book critically evaluates the phenomenon of cryptic species and demonstrates how they can play a valuable role in improving our understanding of evolution, in particular of morphological stasis. It also explores how the recognition of cryptic species is intrinsically linked to the so-called 'species problem', the lack of a unifying species concept in biology, and suggests alternative approaches. Bringing together a range of perspectives from practicing taxonomists, the book presents case studies of cryptic species across a range of animal and plant groups. It will be an invaluable text for all biologists interested in species and their delimitation, definition, and purpose, including undergraduate and graduate students and researchers.

Molecular data from three chloroplast markers resolve individuals attributable to Radula buccinifera in six lineages belonging to two subgenera, indicating the species is polyphyletic as currently circumscribed. All lineages are morphologically diagnosable, but one pair exhibits such morphological overlap that they can be considered cryptic. Molecular and morphological data justify the reinstatement of a broadly circumscribed ecologically variable R. strangulata, of R. mittenii, and the description of five new species.

This section of the Handbook of Zoology is intended as a comprehensive and exhaustive account of the biology of the taxa Gastrotricha, Nematoda, Nematomorpha, Priapulida, Kinorhyncha, Loricifera, Gnathostomulida, Micrognathozoa, Rotifera, Seisonida and Acanthocephala, covering all relevant topics such as morphology, ecology, phylogeny and diversity. The series is intended to be a detailed and up-to-date account of these taxa. As was the case with the first edition, the Handbook is intended to serve as a reliable resource for decades. Many of the taxa of this volume are comparatively unknown to many biologists, despite their diversity and importance for example in meiofaunal communities (Gastrotricha, Rotifera, Gnathostomulida), their fascinating recent discoveries (Loricifera and Micrognathozoa), their importance as parasites (many nematodes, Nematomorpha, Acanthocephala) and their importance for evolutionary questions (e.g. Priapulida, Gastrotricha). The groups covered range from those poor in species (such as Micrognathozoa with 2 known species) to the species-rich and diverse Nematoda and their ca. 20.000 described species. While each taxon is covered by one chapter, nematodes are treated in several chapters dedicated to their structural, taxonomic and ecological diversity.

"The Megophrys major species group (MMSG) is composed of typically medium to large sized frogs. Within the genus, it is the most geographically widespread clade ranging from the western Himalayas to southern Indochina. In this study, we examined in detail the extent of cryptic diversity within the MMSG-Indian populations based on molecular data (up to ten genes) using multigene concatenation and coalescent-based phylogenetic techniques, species delimitation analyses and extensive morphological data.Molecular evidence suggests a high level of hidden cryptic diversity within the MMSG, particularly within the M. major species complex (MMC), highlighting overlapping distributions, a case of potential mitochondrial transfer between two species, and tree topology discordance between phylogenetic methods and mitochondrial and nuclear data sets. Most analyses indicated distinct eastern and western clades in the MMC, and that the western clade may further divide into a northern and a southern subclade.A detailed taxonomic review of Indian members of the Megophrys major species group is provided. Previously undocumented complex nomenclatural issues involving known species are highlighted and resolved. Megophrys monticola is taxonomically redefined for the first time as a valid species since its synonymy with M. parva in 1893. The taxonomic status of two recently described species, Xenophrys katabhako and X. sanu are discussed in light of increased molecular and morphological sampling, and are synonymised with M. monticola. Megophrys monticola and M. robusta are redescribed based on their original type specimens and recently collected material. Megophrys major is neotypified and M. robusta lectotypified to remove prevailing nomenclatural instability. Four new large sized Indian MMC species are formally described from the Northeast Indian states of Arunachal Pradesh, Meghalaya and Nagaland, and Myanmar. All South Asian MMSG species are morphologically diagnosed from known congeners in the group. The geographic distributions of all taxa discussed are significantly redefined based on the revised taxonomy and extensive literature review. Morphological and molecular evidence suggests that Megophrys major sensu stricto might be endemic to Northeast India; M. glandulosa is formally removed from the Indian and Bhutan species checklists. Numerous misidentifications in literature are highlighted and corrected. In order to reduce future misidentifications of species reported from surrounding regions, high definition images of the holotypes of three Chinese species, M. glandulosa, M. medogensis and M. zhangi are provided for the first time, and a detailed description of Myanmar specimens of M. glandulosa is also given. This study provides the principle foundation for further research into the taxonomic status of the remaining, currently undescribed MMC taxa from Southeast Asia. Keywords: Reptilia, nomenclature, molecular systematics, integrative taxonomy, morphology, conservation, natural history"--page 3.

Volume One of the thoroughly revised and updated guide to the study of biodiversity in insects The second edition of Insect Biodiversity: Science and Society brings together in one comprehensive text contributions from leading scientific experts to assess the influence insects have on humankind and the earth’s fragile ecosystems. Revised and updated, this new edition includes information on the number of substantial changes to entomology and the study of biodiversity. It includes current research on insect groups, classification, regional diversity, and a wide range of concepts and developing methodologies. The authors examine why insect biodiversity matters and how the rapid evolution of insects is affecting us all. This book explores the wide variety of insect species and their evolutionary relationships. Case studies offer assessments on how insect biodiversity can help meet the needs of a rapidly expanding human population, and also examine the consequences that an increased loss of insect species will have on the world. This important text: Explores the rapidly increasing influence on systematics of genomics and next-generation sequencing Includes developments in the use of DNA barcoding in insect systematics and in the broader study of insect biodiversity, including the detection of cryptic species Discusses the advances in information science that influence the increased capability to gather, manipulate, and analyze biodiversity information Comprises scholarly contributions from leading scientists in the field Insect Biodiversity: Science and Society highlights the rapid growth of insect biodiversity research and includes an expanded treatment of the topic that addresses the major insect groups, the zoogeographic regions of biodiversity, and the scope of systematics approaches for handling biodiversity data.
