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.). It contains full synonymic and taxonomic information for c. 3,040 valid species and over 4,690 taxonomic names (all ranks, valid and not valid). There are c. 27,000 citations to c. 2500 references. There are also c. 6100 specimen records and more than 11500 images of two thirds of valid species, with more being added to on a regular basis [MANY THANKS TO COLLEAGUES COLLABORATING ON THIS. I HAVE THOUSANDS OF TYPE PHOTOS TO UPLOAD (VARIOUS COLLECTIONS), TAKEN BY OSKAR CONLE & FRANK HENNEMANN]. Keys to taxa may be added at a much later stage.
