TL;DR: Taxonomic changes render Clitarchus endemic to New Zealand and consisting of three species; C. hookeri, C. rakauwhakanekeneke and C. tepaki.
Abstract: We describe two new species of Clitarchus Stal from Northland, New Zealand. Clitarchus rakauwhakanekeneke sp. nov. is described from the Poor Knights Islands and Clitarchus tepaki sp. nov. is described from the Te Paki / North Cape area and the Karikari Peninsula at the northernmost tip of New Zealand. Two new synonymies are proposed including Clitarchus multidentatus Brunner (syn. nov.) and Clitarchus tuberculatus Salmon (syn. nov.) as synonyms of Clitarchus hookeri (White). Clitarchus magnus Brunner, recorded from Thailand, is transferred to Ramulus Saussure and given the replacement name Ramulus changmaiense nom. nov. The holotype of C. multidentatus was recorded as being collected from New Caledonia; however we believe this is a labelling error and the specimen was collected from New Zealand. These taxonomic changes render Clitarchus endemic to New Zealand and consisting of three species; C. hookeri , C. rakauwhakanekeneke and C. tepaki . Keys to the adult males and females of Clitarchus species are given in addition to notes on host plants, ecology and geographic distributions.
TL;DR: A new genus and species of stick insect from Northland, New Zealand, Tepakiphasma ngatikuri is described and due to the presence of certain key synapomorphies it is phylogenetically placed within the Australasian clade Lanceocercata.
Abstract: We describe a new genus and species of stick insect from Northland, New Zealand, Tepakiphasma ngatikuri, gen. nov., sp. nov. We have classifi ed this genus as a member of Phasmatidae, Phasmatinae, Acanthoxylini, and due to the presence of certain key synapomorphies it is phylogenetically placed within the Australasian clade Lanceocercata. A number of character states differentiate Tepakiphasma from other New Zealand Acanthoxylini genera including the number and arrangement of teeth on the claspers and a perforate egg capitulum or capitular cone. Like many New Zealand phasmatodeans the known host plants of T. ngatikuri include species of Myrtaceae. This genus appears to have an extremely limited geographic distribution and is known from only two specimens collected in the Te Paki / North Cape area at the northernmost tip of mainland New Zealand. This discovery further emphasises the importance of the Te Paki / North Cape area in New Zealand biodiversity. The phasmatodean fauna of New Zealand now contains 1...
