Abstract
ABSTRACTMarine strandlines provide habitat for a variety of littoral and terrestrial invertebrates, including arachnids. In this study we recorded spiders in strandlines at 35 sites on Banks Peninsula, New Zealand. On average, only 1.5 named species were recorded per thirty-minute hand search, and many sample visits (30%) recorded no spiders. Species accumulation curves suggested further species could be recorded with further sampling, but these may be tourist species rather than strandline residents. Thirty-eight species were recorded in total, with the introduced theridiid Steatoda capensis being the most common (30 records) and widespread (17 locations). The New Zealand endemic species Otagoa nova (25 records) (Toxopidae), Anoteropsis litoralis (15) and Anoteropsis hilaris (15) (Lycosidae), and the introduced Tenuiphantes tenuis (24) (Linyphiidae), were also common. Spiders were more frequent in strandlines on boulder beaches compared with shingle beaches, although there was no statistical differences in the numbers of species recorded on the different beach types.
