ABSTRACT We describe a new genus and species of stick insect from Northland, New Zealand, Tepakiphasma ngatikuri, gen. nov., sp. nov. We have classified 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 10 genera and 23 described species. KEY WORDS Acanthoxylini, Lanceocercata, Phasmatidae, Phasmatinae, Te Paki. INTRODUCTION The Te Paki/North Cape area at the very northern tip of New Zealand is of high biodiversity value because of the large numbers of endemic plant (e.g., Davidson et al. 1969; Druce et al. 1979; de Lange et al. 2003; von Konrat & Braggins 2005), vertebrate (e.g., Chapple et al. 2008) and invertebrate species (e.g., Gardner 1967; Goulstone et al. 1993; Larochelle & Larivière 2005; Winterbourn 2009). Furthermore, due to the extremely degraded habitat in this area (Gardner & Bartlett 1980; Lux et al. 2009) many of these endemic species are threatened with extinction (Lux et al. 2009). Many vertebrate species have become extinct due to human induced environmental changes and information on the pre-human invertebrate fauna is lacking, with the exception of land molluscs (Brook 1999). Because the Te Paki/North Cape area is a centre of endemism, two collecting trips were undertaken to survey the phasmatodean fauna. In December 2008 we collected a pair of late instar nymphs in Radar Bush, Te Paki Recreation Reserve. These specimens were taken back to the laboratory and reared through to adulthood. Analysis of morphological characters indicated the specimens belong to a new species and genus. This discovery represents the second new phasmatodean species from the Te Paki/North Cape area, the first being an undescribed species of Clitarchus Stål discussed by Buckley et al. (2010a). MATERIAL AND METHODS Specimens and analysis of characters The specimens studied here are lodged in the New Zealand Arthropod Collection (NZAC), Auckland, New Zealand. Higher level nomenclature follows Günther (1953) instead of more recent classifications for reasons outlined in Klug and Bradler (2006). Measurements were made using electronic digital callipers. Specimens were studied and illustrations were prepared using LEICA MZ75, ZEISS Stemi SV6 and ZEISS Stemi SV11 stereomicroscopes at different magnifications and with a drawing tube (camera lucida). Terminology of adult morphological characters follows Beier (1968) and Littig (1942) and that of egg characters Clark Sellick (1997, 1998). The holotype and paratype of this newly described species are stored in the NZAC in 70% and 100% ethanol respectively, as this method of preservation facilitates inspection of the terminalia better than in pinned specimens and ensures the preservation of DNA in 100% ethanol. DNA sequence data from the paratype will be published at a later date. Because the genus is known from only one species and two specimens the generic description is essentially identical to the species description. For this reason we give a diagnosis for the genus, a full species description and a discussion of characters justifying erection of a new genus. 118

Notes on variation As mentioned in the description, the structure of the capitulum shows some variation. Some eggs have a conical capitulum and others have a flat capitulum with a central apical projection resembling a stalk (Figs. 9, 11). Etymology The specific name was selected by the Ngāti Kurī people who are kaitiaki (guardians) of the Te Paki/North Cape area. Type locality and distribution The species is known only from the type locality, near the bottom of the Kauri Bush Track in Radar Bush, Te Paki Recreation Reserve. This locality is known either as Radar Bush or Kauri Bush. The holotype and paratype were collected from two Metrosideros perforata (Myrtaceae) vines, both growing on trees, within a few metres of each other. 122 DISCUSSION Taxonomic status and classification The antennae of Tepakiphasma are longer than the fore femora and this character state is shared with the New Zealand genera Acanthoxyla Uvarov, Clitarchus, and Pseudoclitarchus Salmon, which are placed in Phasmatidae, Phasmatinae, Acanthoxylini. Phylogenetic studies show both the Phasmatidae and the Phasmatinae to be non-monophyletic (Whiting et al. 2003; Bradler 2009; Buckley et al. 2009, 2010b) and so this taxonomic placement is provisional only. Tepakiphasma is a member of the clade Lanceocercata (Bradler 2001) due to the presence of key apomorphies including leaf-like cerci, absence of a vomer, claspers orientated medially against each other and the male clasping the female at the base of the operculum (abdominal sternum 8) (Fig. 2). We have erected a new genus, because Tepakiphasma displays a number of character states not possessed by any other genus of New Zealand stick insect. The most striking character state difference between Tepakiphasma and the remaining New Zealand genera is the morphology of the egg. Clark-Sellick (1997) described the opercular extensions of [ ] most Acanthoxylini as simply raised opercula that cannot be termed capitula. However, Clark-Sellick (1997) also described the structure in question as a closed conical capitulum in Clitarchus and Pseudoclitarchus and as a conical capitular structure in Argosarchus. We follow the latter interpretation, because a perforated operculum would be equivalent to an open capsule and consequently a non-viable egg. The perforated capitulum or capitular cone (Fig. 14) is an apomorphy with regard to all other New Zealand phasmatodean taxa. However, perforated capitula are known from stick insects from other subfamilies in other geographic areas (e.g., Clark Sellick 1997; Baker & Chandrapatya 2001). In Acanthoxyla, Clitarchus and Pseudoclitarchus, the female cerci are all much longer, significantly extending posteriorly beyond the paraprocts (Salmon 1948, 1991; Jewell & Brock 2002), whereas in Tepakiphasma the cerci are only slightly longer than the paraprocts. The relative size of the cerci and paraprocts are similar between Argosarchus and Tepakiphasma; however the cerci of Tepakiphasma are much more rounded apically (Fig. 5, 9) than in Argosarchus. Acanthoxyla lacks males (Salmon 1991), and therefore we are unable to compare the male of Tepakiphasma with males of this genus. However, the number of teeth on the claspers differs between Clitarchus, Pseudoclitarchus, Argosarchus and Tepakiphasma. Clitarchus males have between three and five teeth on each clasper (Fig. 5; Salmon 1991; Buckley & Bradler unpublished data), Pseudoclitarchus has a single tooth per clasper (Salmon 1991) and Tepakiphasma has two teeth on

6 New genus of New Zealand stick insect each clasper (Figs. 3, 4). The claspers of Argosarchus are different from all remaining Acanthoxylini as they possess a cluster of long spine-like teeth at the apex (Salmon 1991). Therefore, the suite of putative autapomorphies displayed by Tepakiphasma and the lack of unambiguously synapomorphic characters with other New Zealand taxa are consistent with its generic status. Natural history and conservation The type locality consists of regenerating forest dominated by various broadleaf trees, Kunzea ericoides, Agathis australis, and the podocarps Dacrydium cupressinum, Halocarpus kirkii, Podocarpus totara and the tree Libocedrus plumosa (Gardner & Bartlett 1980). This area occupies approximately 20 hectares only and is of outstanding biodiversity value because it has the greatest plant diversity of all remaining forest fragments in the Te Paki/North Cape area (Gardner & Bartlett 1980). Furthermore, this forest fragment and the immediate surrounding area is the type locality for a number of beetle (Holloway 1961; Larochelle & Larivière 2005), mirid hemipteran (Eyles 2005), spider (Forster 1970), skink (Chapple et al. 2008), and plant species (von Konrat & Braggins 2005), and is the only known locality of several undescribed species of land snail (e.g., Goulstone et al. 1993). The new, and as yet undescribed, species of Clitarchus discussed by Buckley et al. (2010a) is widespread in the Te Paki/North Cape area including Radar Bush. Both specimens were found on Metrosideros perforata as final instar nymphs, and were observed to feed on this host shortly after collection. In the laboratory they were reared on Lophomyrtus bullata (Myrtaceae) through to adulthood and then kept alive on Metrosideros excelsa (Myrtaceae) for several months. Although T. ngatikuri can survive on at least three species of Myrtaceae, we have not yet collected it from Leptospermum scoparium or Kunzea ericoides (both Myrtaceae), both of which are abundant in the Te Paki area and are known host plants for many other New Zealand Phasmatodea (Salmon 1991; Buckley et al. 2010b). Despite searches at a number of other sites in the Te Paki/North Cape area, this species has not been located beyond Radar Bush. Potential threats to T. ngatikuri include predation by adventive rats, possums and vespulid wasps, all known predators of New Zealand Figures 3-9.

A mammalian control programme is currently underway in the Radar Bush area, and the discovery of a vulnerable endemic stick insect species strongly suggests this programme should be continued long term. In recent years significant fires have occurred in the Te Paki area and destruction of the type locality also remains a threat (Lux et al. 2009). We recommend that surveys of the Te Paki/North Cape area be undertaken urgently to assess the distribution of T. ngatikuri and if necessary conservation management plans put into action.
