Detalle de: On four poorly known harvestmen from New Zealand (Arachnida: Opiliones: Cyphophthalmi: Eupnoi: Dyspnoi: Laniatores)

Despite the unique and interesting nature of New Zealand's Opiliones fauna, little work on these animals has been published since the studies of Forster, whose last harvestman publication appeared nearly half a century ago. Since then, most groups of New Zealand Opiliones have been neglected. Here we provide field observations and live photographs of four poorly known species, one for each of the four Opiliones suborders. We also redescribe Rakaia collaris Roewer, 1942, a species of Cyphophthalmi described on the basis of a single female specimen, and considered a nomen dubium in previous studies. The objective of this study is to highlight the incredible New Zealand opiliofauna and to raise interest in this group of terrestrial arthropods commonly used for biogeographical and evolutionary studies.
