DKK 960.00 excluding postage (subscription discount of 10% if ordered direct from publisher). The Tortricidae represent one of the largest groups of Microlepidoptera with just over 9000 described species. Their vernacular name, ‘leafroller moths’, is derived from the larval habit of many species of feeding concealed within a roll or a fold of a leaf of the host plant. However, the larvae of numerous species employ other diverse feeding habits, including boring in most plant parts, feeding in flowers or on leaf litter or even predating scale insects. Many species are important pests of agricultural, forest and ornamental plants, and such five-star pests as spruce budworm (Choristoneura fumiferana) and codling moth (Cydia pomonella) have attracted considerable research attention. It is almost a century since the last attempt at a world catalogue of the Tortricidae – Edward Meyrick's Lepidopterorum Catalogus volume of 1912 and Genera Insectorum of 1913 – but these dealt only with the Tortricinae (and only a part of that) and covered only a little more than 10% of the species listed here. Therefore, a catalogue of this large and important group of moths is long overdue and this volume is to be welcomed for that reason alone. The introductory sections describe the layout of the catalogue. Names listed include infrasubspecific names and misspellings, flagged as such. Original orthography is retained for all names. Valid names are listed alphabetically within a genus, each with their synonyms; genera are arranged alphabetically with subfamilial and tribal assignment given, together with type species and any synonyms. Authorship, reference and date are given for each name. For species group names, the genus of original combination is given together with the type locality and the status, sex and depository of known type specimens. A list of repository and serial publication abbreviations is given, and the introductory material is completed with a summary of the suprageneric classification of the Tortricidae, including synonyms. Authorship of the systematic catalogue itself is not just by J. W. Brown but also seven of the world's leading experts on the group – Joaqin Baixeras, Richard Brown, Marianne Horak, Furumi Komai, Eric Metzler, Józef Razowski and Kevin Tuck. The layout is clear and the treatment is very user-friendly. The index at the end of the work gives author, date and current taxonomic placement (for species) and this makes the retrieval of names very simple. Extreme care seems to have been taken with the rendering of scientific names and a check of some 500 revealed only a single (one-letter) error. However, treatment of authors' names is somewhat more cavalier, and slightly complex European names occasionally lose letters – Fisher (for Fischer) v. Roeslerstamm, Hoffman (for Hoffmann), Peyerimoff (for Peyerimhoff), Zerney (for Zerny), etc. It is in the type localities where thorough cross-editing by contributors could have worked wonders. As it is, attempts to bring geographical names up to date or to apply a country to a town or a province are sporadic and sometimes wildly erroneous. Misspellings are rife. Tristram is a collector, not a locality, and I quickly noted Baberton for Barberton, Beruit for Beirut, Glogan for Glogau and Granada for Grenada. Oran is not a province of France but, as given correctly on the facing page, of Algeria. Other reviewers have given more extensive lists of examples. Extrapolation is unsafe; although most of the type specimens of Tortricidae described by Meyrick in 1926 from Sarawak were uniques that were sent to Kuching and lost, any duplicates went to London and there is, for example, a perfectly good syntype of Neocalyptis felina in the Natural History Museum, London. Although type locality information in this work should be double-checked before quotation, this hardly detracts from a monumental corpus of well-presented information and the authors are to be congratulated on their successful inventory of a very large slice of Lepidopteran diversity.
