Phyllium (Pulchriphyllium) shurei n. sp. is currently only known from a male specimen, therefore only a key to known Phyllium males Phasmatodea ; West Java ; from Java is included.

The measurements of the holotype were made to the nearest 0.1 mm using digital A new species of leaf insect, Phyllium (Pulchriphyllium) calipers. The holotype is deposited in the Montreal shurei n. sp. is described and illustrated from Java, Insectarium type collection. Indonesia. It is surprising that the island of Java is the type locality for this new species because of the island's popularity as a tourist destination and the breeding center for other popular Phyllium species commercially available (Fig. 1). However, the camouflage of the leaf insect family has allowed many species to be overlooked for years, even in very popular locations. The discovery of Phyllium (Pulchriphyllium) maethoraniae Delfosse, 2015, from Chiang Mai Province of northern Thailand, named from a single unique female specimen, is another surprising discovery from a very popular destination. To date only the holotype male specimen has been recovered of Phyllium (Pulchriphyllium) shurei n. sp., and it is the hope of the authors that the recognition of an additional species from Java will prompt the search for this rare species and for the currently unknown female. Materials and Methods Photo in Fig. 1 was taken by Maman Cahyana in Sukabumi, West Java, Indonesia. Photos in Fig. 2 were taken by the first author at the San Diego Natural History Museum using a Canon 5D Mark II and a MP-E 65mm macro lens and were stacked using Zerene photo stacking software, version 1.04, 64-bit. Photos in Fig. 3 were taken by René Limoges of the Montreal Insectarium using a Nikon D810 DSLR camera with Nikon Micro-Nikkor 200 mm f/4 lens on Manfrotto 454 micrometric positioning sliding plate.
