  • Although dated 2020, two works are available in early 2021 (January?). Nicolas Cliquennois - Phasmatodea chapter in Les Insectes du Monde [proposed, revised classification] which is a tricky area with rank-free names proposed by some workers! We have heard from Francis Seow-Choen that 'A taxonomic guide to Stick Insects of Sumatra' Vol. 2 was published in 2020 (Vol. 1 was published 2018). It will take time for booksellers to stock them, but you can contact the author direct - see list of experts below

The Phasmida Species File (PSF) is a taxonomic database of the world's Phasmida (stick and leaf insects, known as walking sticks and walking leaves in the U.S.), excluding fossil species. There is full synonymic and taxonomic information for 3,380 valid species, 38,200 citations to 3,300 references, over 7,700 specimen records and 17,000 images of 75% of valid species, with more being added to on a regular basis. Another future aim of this database is to provide high quality images of living phasmids in the wild. Images of captive-reared species can be found elsewhere, notably on

Colleagues have kindly collaborated by providing photos of type material [with particular thanks to Oskar Conle & Frank Hennemann].

To see information contained in the database, use the links across the top of the page.  Click on Search to find a specific taxon or other kinds of information.  Clicking on Taxa will make the order Phasmida your current taxon unless you have previously moved to a different taxon in this session.

This website and database use Species File Software.  Information about the design and use of SFS may be found on a separate website.

List of Experts

Leading specialists and others with a serious interest in the fauna have taken responsibility to review information in their areas of expertise — taxonomic and/or geographic.  An explanation of participation in the development of the PSF is also available.  The following lists geographic locations associated with the name of the phasmid taxonomist.
