Hyptiotes paradoxus, also known as the triangle spider, is a cribellate orbweaver in the family Uloboridae.
Body
Adult males have a body length of 3–4 mm (0.12–0.16 in), females 5–6 mm (0.20–0.24 in). The carapace is Broad. It ranges from ginger to dark brown, and has a dense covering of hairs. The abdomen is orange-brown to reddish-brown, with faint black horizontal bands which extend around the sides. It is raised towards the anterior, giving the spider a hunched look, and it may bear a pair of small tubercules on the anterior side. The male has a darker and more cylindrical abdomen than the female, and it lacks the raised anterior. They have short, stout legs, which are coloured as the carapace. Mature males have extremely large pedipalps, similar in size to the carapace.[3]
Eye arrangement
They have eight eyes in two rows, with the posterior row distributed across the midline of the carapace, and the anterior row halfway between the posterior row and anterior edge. The anterior median eyes are close together, and distant from the anterior lateral eyes; the posterior medians are spaced apart, with the posterior laterals on tubules on the side of the carapace, around halfway back.[3]
