This publication is an extract from the CD-ROM ‘Beetle Larvae of the World’ (Lawrence et al. 1999), which can be obtained from CSIRO Publishing (http://publish.csiro.au).
This package is generated from a DELTA database (Dallwitz 1980; Dallwitz, Paine, and Zurcher 1993). It comprises an interactive identification and information retrieval system using the program Intkey (Dallwitz, Paine, and Zurcher 1995, 2000), descriptions, illustrations, references, and other subsidiary material. It allows the identification of larval beetles from any part of the world to the family or subfamily level, and occasionally to tribe or genus.
This is the second release of the package. It includes a new version of Intkey, operating under MS-Windows and with numerous enhancements. Also, natural-language descriptions as HTML and MS-Word files have been added.
The data have not been significantly altered. A few minor corrections have been made, and a few changes have been made in the classification and family-group names, following Lawrence and Newton (1995) and Opinion 1916 of the International Commission on Zoological Nomenclature (I.C.Z.N. 1999).
The database consists of a set of 390 taxa (family, subfamily, tribe or genus), each of which is coded for 174 characters with from 1 to 17 character states (usually 2 or 3). There are 6 additional text characters, which include a short statement on geographic distribution, notes on general biology (habitat, feeding habits etc.), alternate group name(s) (synonymy), taxon images with their accompanying specimen data and acknowledgments, and a short list of references pertaining to a particular taxon.
Most of the characters have been coded from preserved specimens, most of which have been cleared and dissected, and comparisons made with published figures and descriptions; in a few cases, however, character states were obtained from published information alone. In the latter case, it was sometimes necessary to code a character as ‘unknown’.
