S ummary A new type of spring web, spun by spiders of the genus Ulesanis of the Theridiidae, is described. It consists of a straight or Y‐shaped sticky thread. The spider holds one end of the thread in one foot and sits on a twig. When prey is caught it releases the twig and allows the thread to go slack. This behaviour affords a close parallel to the single‐thread cribellated web of Miagrammopes. Two new species of Ulesanis, U. pukeiwa and U. puketoru , are described from New Zealand, and they are compared with other Australasian and Pacific species.
