Created in 1999 and hitherto functioning as amateur resource, the Internet-site Dolichopodidae Homepage contains: General Information, Catalogues, Keys, Bibliography, Net Publications, and (since 2004) a Phototheque, etc. (www.fortunecity.com /greenfield/porton/875/). The parts Catalogues and Net Publications contain both original country lists of species, and links to accessible Internet-resources including catalogues and databases, as a rule created for taxa of a higher rank than family. The site is arranged now in 1170 files (about 50 MB), of which 470 are html-files (about 13 MB). In 2003 a check list of species of the family Dolichopodidae of the World has been published and regularly updated since, being organized as the alphabetic list of genera with hyperlinks to lists of species with full bibliographic descriptions. It includes about 240 genera, 7000 valid species and about 10000 lines with other names of species rank. Experience shows that the remote support of the site and regular updating the world taxonomic check list demands considerable expenses of time and money from the taxonomist, who was engaged to work mainly in a different field of activity. Publication of species lists and other materials as hypertext and tabular hypertext documents allows data retrieval by use of common search engines to find the site in the Internet by a user query "genus - species". In most cases the necessary page of the site appears in the first place after outputting search results. Thus, the submitted information resource favourably differs from relational databases (such as Fauna Europaea) by a minimum number of steps to receive the resulting data.
