Taxonomic revision of Paraphasma Redtenbacher, 1906 (Phasmatodea, Pseudophasmatidae) based on phallic and external morphology. Zootaxa. 5122(1): 1-80.

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 3,464 valid species [+185 subspecies], more than 40,200 citations to 3,460 references, more than 8,100 specimen records and 19,400 images of 81% 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, Royce Cumming and Francis Seow-Choen].

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.
