Rostrum with large, curved dorsal spine. Anterior margin of sternite 3 concave with row of six to eight spines. Sternite 4 with one pair of large lateral spines; surface with scattered small spines and granules only. Abdomen covered with spines; pair of large submedian spines on anterior portions of segments 1–6 each; telson anterior portion covered with denticles. Antennal scale small and triangular, barely reaching midpoint of penultimate article, rudimentary or absent; ultimate article with distal spine; penultimate article unarmed. Maxillipeds 3 widely separated; propodus with two to five spines along extensor margin; ischium with 33 teeth on mesial ridge (including two to three strong teeth on basis). Pereopod 1 (cheliped) slender, palm 2.4–3.0 times as long as dactyli. Pereopods 2–4 carpi seven to eight times longer than propodi.</p> <p>Variation: Baba (1974) gave only one measurement of the carapace length (11.5 mm). The material presented here includes a further 115 specimens with carapace lengths between 6.6 (NIWA 14565) and 19.2 mm (NIWA 14568). Within this size range, the morphometric proportions of the carapace, telson, sternum, and pereopods correspond well with that of the holotype examined. The only significant difference appears to be in the height–width ratio of the cheliped palm with the male holotype palm being nearly 12 times as high as wide. In both small males and females, the palm is more slender (15.5 and 16.3 times as high than wide, respectively).</p> <p>Body sizes of males and females were not significantly different; ovigerous females were generally the largest specimens (range: 9.2–19.2, mean: 12.8, median: 12.8 mm, N = 42), followed by males (range: 6.6–17.5, mean: 12.0, median: 11.9 mm, N = 40). Nonovigerous females were the smallest on average (range: 7.5–15.8, mean: 11.2, median 10.8 mm, N = 34).</p> <p>The size of the ovum ranged from 1.6–2.2 mm in diameter.</p> <p>The large series of specimens examined showed considerable variation in the presence, absence, and size of the antennal scale. Of 58 specimens examined for this character, only six (10%) bore a scale as shown in Baba (1974). Most specimens (70%) showed a rudimentary scale and in 20% of the specimens, the scale appeared to be absent. This character varied even from left to right on the same specimen (Fig. 2), from specimens collected from one station, and no sex or geographical correlation was obvious.</p> <p>The basis of maxilliped 3 usually bears three strong spines (proximal smallest), the holotype lacks the smaller proximal spine.</p> <p>Small differences are noted amongst major spines on the dorsal surfaces of the carapace and abdomen, usually with an additional spine to the characteristic spines noted by Baba (1974). The only exception are two specimens from the NMNZ collection that, unfortunately, lack location information; both females lack the dorsal spine on the carapace but otherwise match the diagnostic characters of G. novaezelandiae.</p> <p>A curious deformation of the rostrum was noted on male NIWA 14572 that had a sagittal split along most of the length of the rostrum (appearing like two parallel rostra and lacking a dorsal spine). Otherwise, the specimen matched the species description well.</p> <p>Remarks: Gastroptychus novaezelandiae Baba, 1974 is a New Zealand endemic and the most common chirostylid in New Zealand waters. It belongs to the group with a concave anterior margin of sternite 3, maxillipeds 3 widely separated, and the P2–4 propodi very short (carpus more than seven times longer than propodus). It is most similar to Gastroptychus brachyteres Baba, 2005 (from the Kei Islands, Indonesia) and Gastroptychus brevipropodus Baba, 1991 (from around New Caledonia) but it can be readily distinguished from both these species by the dorsal spine on the rostrum, the pronounced paired submedian spines on the abdominal tergites 1–6, at least two spines on the extensor margin of the propodus of the third maxilliped, and the lack of prominent submedian spines on the sternal plastron (only scattered granules and very small spines along sternite 4).</p> <p>Distribution: Margins of the New Zealand continental shelf at depths of 264–732 m and from about 34°S (north-east of the North Island) to 53°S (sub- Antarctic slope) (Fig. 3).</p> <p>Ecological and biological remarks: Baba (1974) noted that the holotype of G. novaezelandiae was taken from a dorsal groove of the pennatulacean Balticina willemoesii (Kölliker). The NIWA station register provides notes for occasional collection of pennatulaceans and other cnidarians in the same haul containing G. novaezelandiae and recent benthic imagery taken on the Chatham Rise revealed this species perched on small hydrozoans and gorgonian corals as well as two occasions with specimens walking on the soft sediment (unpubl. data).</p> <p>The female specimen NIWA 14574 carried a sacculinid rhizocephalan parasite under the abdomen. Additionally, some pereopods of the female NIWA 14580, the southernmost record, are thickly covered with solitary hydroids.</p></div> 	https://treatment.plazi.org/id/03E487F2FFD03C49320018C90B0EF18A	Public Domain	No known copyright restrictions apply.

Rostrum sharply triangular. Sternal plastron wider than long along midlength; sternite 3 strongly depressed, anterior margin narrow; deeply emarginated, with pair of median spines. Antennal basal article with distinct outer spine; ultimate and penultimate articles unarmed; antennal scale slightly shorter to slightly longer than peduncle. Pereopod 1 (cheliped) merus with at least one row of large tubercles on inner proximal margin; ischium with stout triangular distodorsal spine. Pereopods 2–4 with proximal portion of the merus dorsal ridge with irregular margin; carpi smooth along dorsal margin; pereopods flexor margin with terminal spines paired, closely followed by penultimate spine and close to juncture with dactylus; dactyli with spines on flexor margin orientated parallel to dactylar margin; length of P4 merus about half that of P3.</p> <p>Variation: The new records agree with the illustrations by Ahyong &amp; Poore (2004) with only minor variations: most specimens bear a pair of epigastric tubercles but in about 10% of the specimens, these are absent (one specimen from NZOI station D836 NMNZ Cr. 012080 bears an additional minute tubercle).</p> <p>The antennal scale is more commonly just short of the antennal peduncle but about 25% of the specimens bear an antennal scale slightly overreaching the antennal peduncle. Large tubercles on the inner margin of the merus are mostly arranged in two short longitudinal rows but may only comprise very few tubercles in small specimens although large males show this character most clearly.</p> <p>Remarks: Uroptychus australis closely resembles Uroptychus empheres Ahyong &amp; Poore, 2004, Uroptychus gracilimanus (Henderson, 1885), Uroptychus vandamae Baba, 1988, and Uroptychus remotispinatus Baba &amp; Tirmizi, 1979 but is distinct from these in the combination of having the antennal scale longer or slightly shorter instead of distinctly shorter than the antennal peduncle, sternite 4 lacking a field of granules and the anterolateral spine falling short of the anterior margin of sternite 3, large tubercles on the proximal flexor margin of the cheliped merus, in having the P4 merus about half instead of two-thirds as long as that of P3, the spines on the flexor margin of the P2–4 orientated parallel to, instead of oblique to the dactylar margin.</p> <p>Henderson’s (1885) type material, from four Challenger stations amongst Indonesia (male and female), Port Jackson (male and two females), and the Kermadec Islands (two females), include three species of which Baba (2005) designated the male from Challenger stn 164 (Port Jackson) as lectotype. The female from Challenger stn 194 (off Banda, Indonesia) and the specimens from Challenger stns 170 and 171 (Kermadec Islands) belong to a different and undescribed species Uroptychus sp. (see below). Uroptychus australis differs from this species in e.g. lacking distinct epigastric spines, the antennal scale nearly reaching or overreaching the antennal peduncle and having inclined spines along the dactylar flexor margin of the walking legs nearly contiguous with the margin.</p> <p>Distribution: This is a widespread south-west Pacific species, currently known from eastern Australia, New Zealand, and Indonesia, at depths of 458–1395 m (Fig. 5).</p> <p>Specimens from NZOI station D836 (NMNZ Cr. 012080) were preserved with pieces of gorgonian coral indicating a possible association of this species with coral.</p></div> 	https://treatment.plazi.org/id/03E487F2FFDB3C4632281AE10F83F54C	Public Domain	No known copyright restrictions apply.

First abdominal tergite with ridge at posterior margin; tergites 2–4 without transverse ridges or grooves. Pleural margins of segments 2 to 4 rounded, tergite 2 wide, slightly concave. Telson 1.7 times as broad as long; posterior portions equal length of anterior portion.</p> <p>Eyes: smooth. Cornea subglobular, 0.5 times length of ocular peduncle, reaching distal quarter of rostrum.</p> <p>Antennal peduncle: Article 2 with distinct outer spine, reaching nearly to midlength of penultimate article of peduncle. Penultimate article with very blunt and lobe-like distal spine (left peduncle with additional, ventral spine). Ultimate article unarmed, 1.1 times as long as penultimate. Antennal scale reaching to midlength of ultimate article; 3.7–4.0 times as long as wide.</p> <p>Maxilliped 3: surface smooth.

Propodus 1.7–2.0 times as long as dactylus; extensor margin smooth; flexor margin with only distal pair of spines. Dactylus straight; flexor margin with spines along distal two-thirds; with five or six spines along flexor margin (excluding distal spine), stout triangular, perpendicular to margin; penultimate spine largest; distal spine very small.</p> <p>Variation and remarks: Uroptychus kaitara sp. nov. belongs in a group of species with an unarmed dorsal carapace, carapace lateral margin with more than three spines, P2–4 propodi without marked distal projection, dactyli penultimate spine extremely broader than ultimate, penultimate not much larger than antepenultimate, remaining spines loosely arranged; a group of species that comprises Uroptychus inclinis Baba, 2005, Uroptychus tridentatus (Henderson, 1885), and Uroptychus zezuensis Kim, 1972. It differs, however, from all these species in having the entire dorsal surface and entire lateral margin of the carapace and anterior margin of tergite 2 covered with small spines (Uroptychus inclinis and Uroptychus tridentatus have seven and Uroptychus zezuensis bears five distinct spines along the anterior lateral margin, the posterior third and posterior carapace margin are unarmed). The dorsal surface is also more sculptured in Uroptychus kaitara with the epigastric and branchial region broadly inflated and separated by a deep and distinct cervical groove (Uroptychus inclinis, Uroptychus tridentatus, and Uroptychus zezuensis are evenly convex with an indistinct cervical groove). Of the closely allied species, only Uroptychus tridentatus with its wide western Pacific distribution shares the distribution range of Uroptychus kaitara; Uroptychus inclinis is only known from the Kei Islands, Indonesia and Uroptychus zezuensis has only been recorded from the northwestern Pacific.</p> <p>Uroptychus kaitara sp. nov. can also be allied to species that have spines along the carapace lateral margin, spines across the entire dorsal carapace surface, and a smooth cheliped palm, such as Uroptychus paku sp. nov., Uroptychus fusimanus Alcock &amp; Anderson, 1899, and Uroptychus sexspinosus Balss, 1913. All of these species, however, have scattered large spines on an otherwise smooth carapace and abdomen, whereas Uroptychus kaitara is densely covered with small spines including the second tergite of the abdomen. Uroptychus kaitara further differs from these three species in having spines along the dorsal margin of P2–4 meri only, whereas Uroptychus paku and Uroptychus sexspinosus have spines along the merus and carpus and Uroptychus fusimanus has unarmed ambulatory legs.</p> <p>The left palm of the cheliped of the holotype is considerably larger than the right. All legs of the holotype are detached.</p> <p>Distribution: Off Macauley Island, Kermadec Islands; 398–412 m (Fig. 7).</p> <p>Etymology: Kaitara is the Māori word for coarse, with reference to the tuberculate dorsal surface.</p></div> 	https://treatment.plazi.org/id/03E487F2FFD93C4031A91D0B0DC4F2CC	Public Domain	No known copyright restrictions apply.

Dorsal surface unarmed, finely granulated. Frontal margin deeply excavate, relatively straight; outer orbital angle produced into small spine. Anterolateral margin with well-developed spine, lateral margin convexly divergent posteriorly, unarmed but irregular, with pair of granules on anterior border of branchial lateral margin, posterior margin unarmed. Rostrum narrow, triangular, slightly deflected ventrally, 0.4 times length of remaining carapace; dorsal surface smooth, glabrous, slightly excavate dorsally; lateral margins with fine lateral serration along posterior two-thirds, unarmed.

Ischium with disto-dorsal and disto-ventral spines (dorsal spine very large and curved). Merus surface with rows of granules, ventral row of eminences and round spines, with two small ventral spines distally. Carpus surface smooth, with two ventral spines distally (small and blunt), carpus 0.6–0.7 times as long as palm. Propodus with palm 2.1–2.2 times as long as high, unarmed. Dactylus 0.3–0.4 times as long as propodus, occlusal margins slightly or not gaping, denticulate.</p> <p>Pereopods 2–4: decreasing in length posteriorly, surface slightly setose and unarmed.

Dactylus gently curved; flexor margin with 11–12 spines along entire length; stout triangular, subequal, slightly decreasing in size proximally; fringe of plumose setae along the extensor margin.</p> <p>Ovum: 1.4–2.7 mm.</p> <p>Variation: The additional material examined can unequivocally be identified as Uroptychus maori. Examination of many specimens reveals that the bilateral asymmetry of the chelipeds and the antennal scale as illustrated by Borradaile (1916) is unusual. The left cheliped is considerably larger than the right in the male holotype but subequal in all other specimens except for the male from NIWA 23134 where the left cheliped is smaller than the right. The left antennal scale is shorter and narrow triangular in the holotype but examination of the material shows that the more common form is the larger scale of the right scale of the holotype: nearly reaching the end of the peduncle, rounded and at least 1.5 times as wide as the peduncle. The asymmetries can probably be attributed to regrowth of a lost appendage.</p> <p>Notes on variation from the holotype are as follows: the granulation and spination of the ischium and merus of the cheliped are more pronounced in large specimens with two large spines along the ventral margin of the merus. The rostrum of the male from NIWA 23134 is stunted, shorter than the ocular peduncle. Females appear larger than males (females’ carapace length range: 17.5–20.5 mm, mean: 19.0 mm; males from 12.0– 15.3 mm, mean: 13.4). The propodal palm is more massive in females with a height–width ratio of 2.2–2.6 for males and 3.3–3.5 for females (holotype male is 2.1–2.2). Large specimens have up to 14 inclined spines along the flexor margin of the propodus of the walking legs.</p> <p>Remarks: Uroptychus maori Borradaile, 1916 most closely resembles the species with denticulate lateral carapace margins and massive chelipeds: Uroptychus brucei Baba, 1986, Uroptychus litosus Ahyong &amp; Poore, 2004, and Uroptychus nitidus occidentalis Faxon, 1893. Uroptychus maori differs from Uroptychus brucei in having the rostrum not deeply excavate, the absence of spines on antennal article 4 where Uroptychus brucei bears a distal spine, Uroptychus maori has spines on P2 propodus along less than three-quarters of length of flexor margin, Uroptychus brucei has spines along the entire flexor margin of the propodus, the anterior margin of sternite 3 is angular in Uroptychus maori whereas produced to spines in Uroptychus brucei. Uroptychus maori differs from Uroptychus litosus in the shape of the carapace, with Uroptychus litosus lateral margins distinctly convex posteriorly whereas Uroptychus maori has more subparallel lateral margins; Uroptychus maori has a finely granulated dorsal carapace surface where the carapace is smooth in Uroptychus litosus; very strong anterolateral spines, distinctly overreaching the outer orbital spine (the anterolateral spine only slightly overreaches the outer orbital spine in Uroptychus litosus); the anterior margin of sternite 4 is rounded and entire (laterally serrated and with strong anterior spine in Uroptychus litosus) and Uroptychus maori has a more elongate cheliped (ratio of cheliped length to carapace length for Uroptychus maori 2.8–3.5 for the longer cheliped and Uroptychus litosus approximately 2). Uroptychus maori differs from Uroptychus nitidus occidentalis in the fine granulation of the carapace surface (the latter having a smooth surface), in the shape of anterior margin of sternite 3 (medially produced angular margin and overreaching lateral angle in Uroptychus maori and laterally produced to spine, overreaching medial angle in Uroptychus nitidus occidentalis); in the relative length of the articles of the antennal peduncle (in Uroptychus maori, the ultimate article is 2.3 times as long as the penultimate, whereas in Uroptychus nitidus occidentalis, the two are subequal).</p> <p>Uroptychus maori also differs from all the above species by the extremely large and curved spine on the distodorsal margin of the ischium of the cheliped and the presence of plumose setae on the extensor margin of the dactyli of the walking legs.</p> <p>Of all closely allied species, the distribution range of Uroptychus maori is most proximate to Uroptychus litosus (known from Tasmania). Uroptychus brucei has only been recorded from north-western Australia and Uroptychus nitidus has a known Atlantic and north-western Pacific distribution range.</p> <p>Distribution: Three Kings Islands north of the North Island of New Zealand from a depth of 183 m (type locality) and now from the West Norfolk Ridge, the Three Kings Ridge, and the Bay of Plenty (Fig. 5); 183– 700 m.</p></div> 	https://treatment.plazi.org/id/03E487F2FFDF3C5C31E71AAC0CE6F522	Public Domain	No known copyright restrictions apply.

Uroptychus paku is closely allied to Uroptychus sexspinosus Balss, 1913 and Uroptychus fusimanus Alcock &amp; Anderson, 1899 but differs from both in dorsal carapace ornamentation and rostrum. Uroptychus sexspinosus has six lateral carapace spines and a number of equally sized spines on the epigastric, hepatic, cardiac, and branchial regions. In contrast, Uroptychus paku has five spines on the lateral carapace margin and only eight dorsal spines (the paired branchial spines being much larger than the remaining spines). Furthermore, the rostrum in Uroptychus sexspinosus is half the length of the remaining carapace, whereas the rostrum of Uroptychus paku is nearly as long as the remaining carapace. Uroptychus fusimanus differs from Uroptychus paku in having the dorsal carapace surface with many spines in more or less distinct rows, seven spines along the convex lateral carapace margin (see above for Uroptychus paku), rostrum simple (distally serrated in Uroptychus paku) and shorter than half length of remaining carapace (nearly as long as carapace in Uroptychus paku), P2–4 meri and carpi unarmed (dorsally furnished with strong spines in Uroptychus paku).</p> <p>Neither of these species have a distribution that is close to Uroptychus paku; Uroptychus sexspinosus is known from Japan and Uroptychus fusimanus is known from India.</p> <p>Distribution: North of L’Esperance Island, Kermadec Islands, 122–307 m (Fig. 7).</p> <p>Etymology: Paku is the Māori word for small or tiny, a reference to the small size of the specimen.</p></div> 	https://treatment.plazi.org/id/03E487F2FFC63C5B31891F020DF5F2C2	Public Domain	No known copyright restrictions apply.

Dactylus 0.5 times as long as propodus; occlusal margins not gaping, denticulate.</p> <p>Pereopods 2–4: similar (meri slightly shortening from P2–4), surfaces setose, unarmed.

The two paratypes agree well with the holotype female in proportions and spination. The frontal margin of the sternal plastron bears small submedian spines in both paratype specimens (a spine is only visible on one side of the holotype) indicating that submedian spines adjacent to the median notch is the more common condition. The cervical groove is more distinct in the male paratype and the left antennal scale falls short of the midlength of the ultimate antennal article (the right scale is normal). The female paratype has only been preserved with a single walking leg, the dactylus bears six spines in addition to the ultimate spine (instead of seven for holotype and male paratype). The palm of the cheliped of the small female paratype is more slender but comparable to the left cheliped of the female holotype (4.4 and 4.0 for paratype, 3.74 and 2.52 for holotype). The male paratype is missing its chelipeds; however, the particularly robust right cheliped accompanying the holotype probably belongs to the male paratype (the suture lines appear to match).</p> <p>Remarks: Uroptychus rutua sp. nov. is most closely related to Uroptychus toka sp. nov. with respect to carapace shape and size and armature of the abdomen, maxilliped 3, pereopods, and sternal plastron. Their relationships are discussed under that species (see below).</p> <p>Uroptychus rutua is closely allied to species with unarmed dorsal and lateral carapace surfaces, maxilliped 3 unarmed, with distal pair of spines on P2–4 propodi, dactyli with six or seven spines along the flexor margin. This includes Uroptychus paenultimus Baba, 2005, Uroptychus glaber Baba, 1981, and Uroptychus tomentosus Baba, 1974. Uroptychus rutua is readily distinguished from these by the strongly convex carapace with distinctly elevated epigastric inflations and a field of spinules on the hepatic carapace region (all three species have very shallowly convex and smooth carapace curvature without spines on the dorsal surface). Uroptychus paenultimus further differs from Uroptychus rutua in having an acute frontal margin of the sternal plastron (rounded in Uroptychus rutua), maxilliped 3 merus with spines (unarmed in Uroptychus rutua) and eight or nine slender and inclined spines on the P2–4 dactyli (seven sharp triangular spines arranged perpendicular to margin in Uroptychus rutua). Uroptychus tomentosus can further be distinguished from Uroptychus rutua by carapace size (6.4–17.7 mm for Uroptychus tomentosus and 3.6–3.9 mm for Uroptychus rutua) and length of P2–4 dactylus (less than half length of propodus for Uroptychus tomentosus and more than half length for Uroptychus rutua). Finally, Uroptychus glaber additionally differs from Uroptychus rutua in having an unarmed antennal peduncle.</p> <p>The record for Uroptychus rutua overlaps with the distribution range for Uroptychus tomentosus whereas Uroptychus paenultimus and Uroptychus glaber are known from Indonesia and Japan, respectively.</p> <p>Distribution: Raoul Island, Kermadec Islands, 165– 180 m (Fig. 7).</p> <p>Etymology: Rutua is the plural Māori word for bump or bulge with reference to the paired inflations on the anterior portion of the dorsal carapace.</p></div> 	https://treatment.plazi.org/id/03E487F2FFC43C5432FF1A000D17F250	Public Domain	No known copyright restrictions apply.

Sternal plastron at least three times wider than long; sternite 3 anterior margin widely and shallowly excavated, with small median notch. Rostrum short, barely reaching or slightly overreaching ocular peduncle. Antennal peduncle unarmed, ultimate and penultimate articles subequal length; antennal scale barely reaching end of antennal article 4. Maxilliped 3 unarmed; ischium with obsolete denticles on mesial ridge. Pereopod 1 (cheliped) slender, 4.8–5.7 times as long as carapace; ischium with stout distodorsal spine; merus and carpus with at least one terminal dorsal spine. Pereopods 2–4 slender; meri and carpi smooth along dorsal margins; carpi long, slightly shorter than propodi on P2–3, much shorter on P4; propodi unarmed; P4 propodus 0.4 times length of P2 propodus; propodus and dactylus subprehensile and subequal in length, gaping when folded, margins bearing plumose setae; flexor margin of dactylus with 9–16 spines nearly perpendicular to margin, all spines obscured by dense setae.</p> <p>Variation and remarks: Uroptychus scambus Benedict, 1902 is a widespread Indo-West Pacific species and very distinct with its very wide carapace and sternum (wider than high for both characters), short rostrum (at most slightly overreaching the ocular peduncles) and subprehensile and setose propodus and dactylus of the walking legs. The New Zealand Uroptychus scambus closely agree with the description by Kensley (1981) for South African material.</p> <p>Sexual dimorphism is not only significant with respect to the size of the cheliped palm but also in the height–width ratio of the sternal plastron. Male specimens have a more massive cheliped propodal palm than females (height–width ratio for males: 3.0–3.6; females: 3.7–4.0) and females have a significantly wider sternal plastron than males (height–width ratio for males: 3.2–3.8; females: 6.1–7.5) with the highest height–width ratio in ovigerous females where the sternum is both increased in width and simultaneously reduced in height in large females. This probably enlarges the cavity under the abdomen and may allow the females to support more eggs (female NIWA 10136 carried 14 eggs, each a diameter between 1.22 and 1.59 mm).</p> <p>The cheliped spination increases with body size, with the cheliped carpus in the largest male (ZMUC CRU–11506) bearing ten strong spines along its mesial margin. None of the New Zealand specimens had spines along the mesial margin but the largest specimens had a row of up to nine strong granules, progressively diminishing in number and size in smaller specimens. Additionally, large specimens also have two or three terminal spines on the carpus and merus in addition to the strong distodorsal spine.</p> <p>The small female (NMNZ Cr 012089) had a small kentrogonid rhizocephalan under its abdomen.</p> <p>Distribution: East coast of South Africa, Andaman Sea, Nicobar Islands, Indonesia, Japan, New Zealand, and Tasman Sea, 296–2084 m. In New Zealand, U. scambus has been found between 452 and 1129 m (Fig. 5).</p> </div>	https://treatment.plazi.org/id/03E487F2FFCB3C5731A71A260FB0F2E0	Public Domain	No known copyright restrictions apply.

Rostrum 0.4 times as long as remainder of carapace, anteriorly rounded. Pterygostomian flap granulate, anterior portion covered with serrate ridges, with sharp anterior spine. Sternal plastron wider than long along midlength, sternite 3 with round anterior margin and semicircular median notch; sternite 4 entire. Abdomen unarmed, setose. Cornea small. Antenna stout; penultimate article with small distal spine; ultimate article unarmed; scale barely overreaching penultimate article to barely reaching midlength of ultimate article. Maxilliped 3 unarmed. Pereopod 1 (cheliped) slender, three times as long as carapace, setose and unarmed except small distodorsal spine on ischium. Pereopods 2–4 sparsely to strongly setose; meri smooth to irregular on proximal portion of dorsal crest, unarmed; carpi smooth along dorsal margin; propodi with pair of distal movable spines only; dactyli broad relative to length, less than half length of propodus, with three to six spines, loosely arranged, flexor margin with ultimate spine smaller than penultimate, subequal to antepenultimate.</p> <p>Variation: Variations from the original account by Baba (1974) include the length and shape of the antennal scale. The length of the scale ranges from barely overreaching the penultimate to reaching to the middle of the ultimate article of the antennal peduncle, whereas the width of the scale remains 1.6–1.7 times that of the antennal peduncle (1.6 in the paratype) (Fig. 15 shows short scale of ovigerous female of NIWA 10900). More commonly, the scale terminates in a more round tip than illustrated in the holotype. One female (Mu 68–81, NMNZ Cr. 012092, south-east New Zealand) bears two small distal spines on the penultimate article.</p> <p>The new records support Baba’s (1974) remarks on variation regarding the degree of setation of the body and appendages varying from densely setose to moderately setose with no clear pattern related to sex or size. With regards to the spination of the dactyli of the ambulatory legs, specimens most commonly (60%) bear five spines, larger specimens more often bear six spines, and smaller specimens bear three to four spines.</p> <p>Further variation is exhibited in the length–width ratio of the carapace, 1.2 in paratype female, slightly more in smaller specimens (1.3 in 8.5 mm male, NIWA 10900) and slightly less in large specimens (1.1 in 14.3 mm female, NIWA 23138).</p> <p>Females are generally larger than males (range of carapace length for ovigerous females: 10.4 to 17.3 mm, mean 14.6 mm, median 14.3 mm; females: 4.3 to 16.8 mm, mean 11.0 mm, median 11.8 mm; males: 6.4 to 17.7 mm, mean 10.6 mm, median 9.5 mm).</p> <p>Large males show slightly gaping fingers of the cheliped.</p> <p>The female paratype and the large female of the (NMNZ Cr. 012096, south-east New Zealand) are infected with akentrogonid rhizocephalans on the ambulatory legs, the antennae, and the third maxilliped. Additionally, two specimens are infected by kentrogonids beneath the abdomen (two kentrogonids on NIWA 23158; one large sacculinid rhizocephalan on NIWA 23160).</p> <p>Remarks: Uroptychus tomentosus is recognizable by its setaceous body and appendages, round rostrum, small ocular peduncle, rounded frontal margin of the sternal plastron with a U-shaped median notch, short, rounded antennal scale, and the short dactyli of the ambulatory legs with three to six widely spaced spines.</p> <p>The female paratype matches the description of the holotype. It represents the only female of the type series of seven specimens and was collected from close to the type locality and at a similar depth.</p> <p>Uroptychus tomentosus is most similar to Uroptychus pilosus Baba, 1981, which shares the short antennal scale and short P2–4 dactyli. Uroptychus tomentosus differs from Uroptychus pilosus by having a distinct anterolateral and postorbital spine (vs. rounded), a small (sometimes minute) distal spine on the penultimate antennal article (vs. unarmed), and by having three to six spines on the dactyli of the walking legs (vs. only two terminal spines).</p> <p>Distribution: Chatham Rise, east of New Zealand’s South Island (between 43° 09′S and 44° 50′S), at depths of 116– 382 m. This species is one of the more common New Zealand chirostylids and appears to be endemic to the continental shelf of the eastern coast of New Zealand (Fig. 16). Its range is extended to the northern tip of New Zealand (34°08′S) and to the Bounty Islands to the south (48°13′S) from a depth range of 64– 540 m.</p></div> 	https://treatment.plazi.org/id/03E487F2FFCE3C5331C71A8D0B56F5A4	Public Domain	No known copyright restrictions apply.

Rostrum short, deflected ventrally, 0.2 times the length of remaining carapace, round apex; dorsal surface smooth, sparsely setose, and shallowly convex; lateral margins smooth. Pterygostomian flap lateral surface with few granules, anterior margin produced into a small spine.</p> <p>Sternum: sternal plastron as wide as long, lateral extremities slightly divergent between sternites 5–7, serrated along lateral margins, surface smooth except for transverse row of granules on sternite 4. Anterior margin of sternite 3 with median notch flanked by pair of submedian spines; lateral margins produced to strong tooth. Sternite 4 two times as wide as sternite 3, anteriorly shallowly concave; anterolateral margin produced to tooth (not overreaching sternite 3 but reaching base of anterolateral tooth).</p> <p>Abdomen: tergites smooth and unarmed, with very few setae. First abdominal tergite with shallow ridge at anterior margin. Pleural margins of segments 2–4 rounded; tergite 2 wide, slightly concave. Telson and tergite 6 two times as broad as long, distal portion emarginate, length 1.4 times that of proximal portion.</p> <p>Eyes: cornea subglobular, 0.4 times length of ocular peduncle, overreaching rostrum.</p> <p>Antennal peduncle: article 2 with blunt distolateral spine.

Antennal scale reaching to midlength of ultimate article; 2.1–2.2 times as long as wide.</p> <p>Maxilliped 3: surface smooth, ischium without distal spines, 12 teeth on mesial ridge (four or five strong spines on basis). Merus, carpus, propodus, and dactylus unarmed.</p> <p>Pereopod 1: stout, 2.7 times as long as carapace (3.3 excluding rostrum), surface smooth, fingers furnished with long setae. Ischium with dorsal and ventral spines distally and with row of spinules on ventral margin. Merus with rows of granules, ventral row of spines, with two ventral spines distally. Carpus sparsely tuberculate on ventral surface, with two small, round ventral spines distally, carpus 1.1–1.2 times as long as palm. Propodus with palm 2.4–2.5 times as long as high, unarmed. Dactylus 0.3 times as long as propodus, occlusal margins slightly gaping, denticulate, with distinct distal process.</p> <p>Pereopods 2–4: decreasing in length and spination posteriorly (merus of P4 0.7 times merus of P2), surface slightly setose (distally furnished with long setae). Merus unarmed, 1.3–1.0 times as long as propodus (P2 longest). Carpus unarmed. Propodus 2.0–2.2 times as long as dactylus, extensor margin smooth.

This group of species includes Uroptychus litosus Ahyong &amp; Poore, 2004, Uroptychus nitidus (Milne Edwards, 1880), Uroptychus similis Baba, 1977, and Uroptychus indicus Alcock, 1901. Uroptychus webberi can be readily distinguished from these species by the parallel carapace margin with distinct and wide ridge along posterior third, round rostrum overreached by ocular peduncle and broader antennal scale (approximately half as wide as long).</p> <p>The truncation of the rostrum could also be a result of damage and confirmation of this condition is pending collection of further specimens. Only the third pereopods remain attached to the body and the left second pereopod is missing in the holotype.</p> <p>The record for Uroptychus webberi is closest to the known distribution of Uroptychus litosus, known from Tasmania. Uroptychus nitidus has a known Atlantic and north-western Pacific distribution range, Uroptychus similis has been recorded from Midway Island, Hawaii, and Uroptychus indicus is widespread in the Indian Ocean.</p> <p>Distribution: Off Macauley Island, Kermadec Islands, 610–640 m (Fig. 7).</p> <p>Etymology: Named in honour of Richard Webber, Curator of Crustacea, National Museum of New Zealand Te Papa Tongarewa, Wellington for his contributions to New Zealand crustacean taxonomy, for providing material for this work, and his general support.</p> </div>	https://treatment.plazi.org/id/03E487F2FFCC3C6C320B1E680CC9F7C9	Public Domain	No known copyright restrictions apply.

Propodus about two times as long as dactylus, extensor margin smooth; flexor margin with only distal pair of spines. Dactylus straight; flexor margin with six spines along distal two-thirds of flexor margin; ultimate small, penultimate largest, preceded by successively diminishing, loosely arranged spines perpendicular to margin.</p> <p>Ovum: 0.6–0.7 mm.</p> <p>Remarks: Uroptychus yaldwyni sp. nov. belongs to the group of small-bodied species with spines or granules on lateral carapace margin, unarmed dorsal carapace surface, sternite 3 with median notch, P2–4 dactylar spines loosely arranged, and penultimate spine not extremely broad. Uroptychus yaldwyni is most closely related to Uroptychus altus Baba, 2005, Uroptychus paenultimus Baba, 2005, and Uroptychus wolffi Baba, 2005. It can be distinguished from these three species by the presence of six or seven small, slender spines on the lateral branchial margin of the carapace with an additional small spine on the anterior border of the anterior branchial region, a very strong anterolateral spine, nearly level with the dorsal margin of the ocular peduncle, a distinct cervical groove, distinct ridge along proximal third of lateral carapace margin, unarmed maxilliped 3, and dactylar spination of the walking legs: Uroptychus yaldwyni has four large triangular spines proximal to two distal spines, directed perpendicular to the flexor margin, whereas U. altus, U. paenultimus, and U. wolffi have three, eight to nine, and six slender and inclined spines proximal to two distal spines, respectively. Additionally, the cheliped is more slender and elongate in Uroptychus yaldwyni (4.2 times as long as carapace, palm greater than 4.5 times as long as broad; in Uroptychus altus the cheliped is 2.7 times as long as carapace, palm 1.9 times as long as broad; in Uroptychus paenultimus, the cheliped is three times as long as carapace, the palm is three times as broad as long; in Uroptychus wolffi the cheliped is 3.3 times as long as the carapace, the palm is three times as broad as long).</p> <p>Uroptychus yaldwyni is also very similar to Uroptychus amabilis Baba, 1979 in carapace shape and size. Uroptychus amabilis, however, does not bear spines along the lateral carapace margin, has spines on the mesial ridge of the maxilliped 3, a distal spine on the distal antennal article, the antennal scale nearly reaching the end of the antennal peduncle, and the dactyli of the walking legs shorter than half length of the propodi.</p> <p>All legs of the holotype are detached.</p> <p>The record for Uroptychus yaldwyni is closest to the known distribution of Uroptychus amabilis from New Caledonia. All others, Uroptychus altus, Uroptychus wolffi, and Uroptychus paenultimus have only been recorded from the Kei Islands, Indonesia.</p> <p>Distribution: Macauley Island, Kermadec Islands, 398–412 m (Fig. 7).</p> <p>Etymology: Named in honour of the late Dr John C.
