A study of the members of the tribe Phasmatini Gray, 1835, that occur within the boundaries of Wallacea (Phasmatodea: Phasmatidae: Phasmatinae: 'Lanceocercata')

摘要

The tribe Phasmatini Gray, 1835 predominantly includes very striking stick insects of remarkable size, most of which are characteristic for their large and often colourful wings. The tribe represents roughly half of the Giant Stick Insects of Wallacea, a subregion in Eastern Indonesia comprising thousands of islands that are separated by deep water straits from the continental islands to the west (Sundaland: Borneo, Java and Sumatra) and East (New Guinea). Within Wallacea the Phasmatini are represented by four genera, namely Anchiale Stal, 1875, Eurycnema Audinet-Serville, 1838, Paracyphocrania Redtenbacher, 1908 and Phasma Lichtenstein, 1796. Currently eight distinct species are known to occur in the Wallacea. Two of these are newly described in the present paper, this is Anchiale buruense sp. n. and Paracyphocrania major sp. n..
