  • JULY 2019 Phasmid Study Group members watched a superb 25 min film on Dryococelus australis by Asher Flatt at the Natural History Museum. For a trailer, see The latest lavishly illustrated Seow-Choen book was published Feb 2020: Stick Insects of Borneo Vol. 3. This updates previous volumes by the same author and Bragg, a new checklist to 369 species or subspecies accounts for new synonymny and combinations is included. However, this still omits Hoploclonia abercrombiei Bragg, 1995, which was re-instated as a Borneo sp. in 2018.

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.). There is full synonymic and taxonomic information for 3,350 valid species and 5,300 taxonomic names, 37,700 citations to 3,200 references, over 7,600 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].
