Tetragnatha arborea Urquhart, 1891: 172 View in CoL , pl. 21, fig. 9. Syntypes not examined, description and illustrations accurate enough to make reliable identification.
TYPE MATERIAL: The syntypes (males and females, from New Zealand, North Island, Stratford, Taranaki) are not at the Canterbury Museum (Nicholls et al., 2000) and are probably lost (C. Vink, in litt., to G.H.).
DIAGNOSIS AND DESCRIPTION: See genus diagnosis and description. Female description based on specimens (TEAU026, TEAU047). Male description based on specimen (TEAU028).
VARIATION: Females (N = 2) total length 8.36– 9.13. Cephalothorax length 3.63–4.12, width 2.73–3.14. Femur length 4.91–5.80.
DISTRIBUTION: Tawhai arborea is found in New Zealand’s North Island (fig. 55).
NATURAL HISTORY: Tawhai arborea builds vertical orb webs with open hubs, few radii, and sticky spirals. The web illustrated in figure 5C had a height of 34 cm (from top to bottom spiral thread). Forster and Forster (1999: 166, fig. 11.28a) describe their webs as large, “up to a metre wide, with widely spaced sticky threads. They are also found within the forest, and their webs may be tilted at a slight angle over running water.”
REMARKS: Tetragnatha arborea was considered a synonym of Orsinome lagenifera , but these species differ considerably in their morphology. Tawhai arborea was misidentified in the phylogenetic analysis of Wheeler et al. (2017) as “ Allende sp. CG103.” Our phylogenetic analysis suggests that both Taraire and Tawhai are not close relatives of Orsinome .
