Types. Holotype male (Colenso's type for Hemideina longipes) in Canterbury Museum Collection. Paratype female in Hudson Collection, Dominion Museum. Male and female paratypes in Dominion Museum Collection. Pachyrhamma longipes has no close affinities to any of the species so far placed in the genus Pachyrhamma. It differs from the other species in: 1 The relatively small number of spines on the hind tibiae. 2. Absence of spines, other than apical ones, from hind tarsi. 3. Shape of the subgenital plate of female. Pachyrhamma waitomoensis n. sp. Text-figure 2. Figs. 1–5. Colour. Basic colour light brown, with anterior and posterior borders of pronotum and posterior borders of mesonotum, metanotum and abdominal terga dark brown; lateral borders of pronotum and mesonotum mid brown; nota irregularly mottled with light and mid brown; abdominal terga mottled with mid brown, light brown and ochrous; femora and tibiae banded with ochrous and light brown, mid brown at their junctions; tarsi pale ochrous; antennae light brown; ovipositor deep reddish-brown. Body Length up to 33 mm; average length in male 32 mm; average length in female 30 mm. Antennae in male 5.5–6 times as long as body, and in female 4.8–5.3 times as long as body. Fastigium almost as high as long. Cerci long, tapering in female, but rounded terminally in male, unsegmented, clothed with long and short setae. Antennae. As in generic description. Sexual dimorphism poorly developed, antennae of male slightly stouter at base and longer than female; no spines present on flagellum of male or female. Legs. Long and slender. Fore and middle legs subequal, with hind leg slightly less than twice length of fore or middle legs in female, and slightly more than twice length of fore or middle legs in male. Sexual dimorphism is shown by fore and middle legs of female being 0.8 as long as male, and hind legs of female 0.66 as long as male. Fore and middle femora unarmed, hind femora bearing a variable number of linear spines beneath; fore, middle and hind tibiae and two proximal segments of hind tarsi armed with variable numbers of linear spines (Table II) No spines occur on fore or middle tarsi. Apical spines constant in number, as in generic description. On hind tibiae prolateral apical spur longer than retrolateral one, both clothed with short setae. Ratios of lengths of legs to length of body: fore leg, male, 1.9:1; female, 1.8:1. Middle leg, male, 2:1; female, 1.7:1. Hind leg, male, 4.6:1; female, 3.2:1. Genitalia Female: Suranal plate, Fig. 1 (SAP), rounded laterally, with terminal margin emarginate and bearing two groups of setae Subgenital plate, Fig. 2 (SGP), concave laterally, terminal margin deeply emarginate, whole plate very sparsely clothed with setae. Male: Suranal plate, Fig. 4 (SPL), convex laterally, slightly emarginate terminally. Subgenital plate Table II.—Variability in Number of Linear Spines on the Legs Pachyrhamma waitomoensis n.sp.
