Legs. Long and slender. Fore and middle legs subequal in length, with hind leg 1.7 length of fore and middle legs. Femora, tibiae and two proximal segments of hind tarsi armed with variable numbers of linear spines. Fore femur unarmed; fore tibia bears three prolateral and three retrolateral inferior linear spines; fore tarsus unarmed. Middle femur unarmed; middle tibia bears two prolateral and three retrolateral inferior linear spines; fore tarsus unarmed. Middle femur unarmed; middle tibia bears two prolateral and three retrolateral inferior linear spines; middle tarsus unarmed. Hind femur bears two prolateral inferior linear spines; hind tibia bears twenty-seven or twenty-eight prolateral and twenty-seven or twenty-eight retrolateral superior linear spines; proximal segment of hind tarsus bears three or four prolateral and five retrolateral superior linear spines; second segment of hind tarsus bears two prolateral and two retrolateral superior linear spines. Apical spines constant in number, as for generic description. First segment of hind tarsus equal in length with other three segments together. Ratio of length of legs to length of body: fore leg, 1.7:1; middle leg, 17:1; hind leg, 2.8:1. Genitalia. Male: Suranal plate, Fig. 1 (SPL), sides convex proximally, notched 0.57 from proximal end; distally the plate is trilobed, each lobe rounded apically; three lobes thickly clothed with setae; rest of plate sparsely clothed with setae. Subgenital plate (hypandrium), Fig. 2 (H), 1.3 wider than long. Lateral margin convex. Distally between the insertion of the styli the plate is trilobed, the median lobe being pointed at the apex and strongly keeled; with lateral lobes longer, rounded and thickly clothed with setae; proximal portion of plate thickly clothed with setae, more distal portion of plate sparsely clothed with setae. Subgenital plate covers genitalia. Disto-laterally it bears two styli (S), one on each side, thickly clothed with setae, length of styli being 0.5 length of sternite IX. Pseudosternite, Figs. 1, 2 (PD), wider than long, convex laterally, tapering to concave proximo-distally with a rounded apex; on dorsal surface it is curved back on itself for a short distance. Locality. Banks Peninsula (type locality). Types. Lectotype male in Canterbury Museum Collection. Female unknown. Pleioplectron diversum Hutton, 1897. Text-fig. 3, figs. 1–2. 1897. Pletoplecton diversum Hutton, Trans, N.Z. Inst., 29: 235. 1899. Miotopus diversus (Hutton), Hutton, Trans. N.Z. Inst., 31::41. In 1897 Hutton added another new species to his genus Pleioplectron as P. diversum. It was described from a single female specimen collected by S. H. Drew from Upper Wanganui. The original material has been examined by the author and compared with Hutton's description, from which it differs in a number Text-fig. 3 —Pleioplectron diversum Hutton.
