description: <i>UROPTYCHUS POLITUS</i> (HENDERSON, 1885) <i>Diptychus politus</i> Henderson, 1885: 420 [type locality: Kermadec Islands, 28° 33.00′S, 177° 50.00′W, 1098 m, 15.vii.1874, <i>Challenger</i> stn 171]. <i>Uroptychus politus.</i> – Henderson, 1888: 178, pl. 6: fig 2 a, b. – Thomson, 1899: 196 (list). – Baba, 1974: 387, fig. 5. – Baba, 2005: 219 (key), 230 (list). <i>Type material:</i> 1 ovig. &amp;female;, syntype, (7.2 mm), Kermadec Islands, 28° 33.00′S, 177° 50.00′W, 1098 m, 15.vii.1874, <i>Challenger</i> stn 171 (BMNH 1888: 33). <i>Diagnosis:</i> Carapace distinctly longer than broad, smooth and unarmed on dorsal surface; lateral margin unarmed, convexly divergent posteriorly; anterolateral spine relatively small, distinctly posterior to lateral orbital spine. Rostrum narrow triangular. Corneal width distinctly more than half length of ocular peduncle. Sternal plastron approximately as long as broad; sternite 3 posteriorly delimited by weakly convex depression, anterior margin moderately concave with small median notch flanked by submedian spines; sternite 4 smooth on ventral surface, anteriorly ending in tooth, not reaching anterior end of sternite 3. Abdomen smooth and unarmed. Antenna slender, articles 4 and 5 unarmed; antennal scale not reaching beyond midlength of article 5. Ischium of maxilliped 3 mesial ridge with mostly obsolescent spines; other segments unarmed. Pereopod 1 (cheliped) three times as long as carapace; merus and carpus with pair of stout ventrodistal spines, ischium with small distodorsal spine. Pereopods 2–4 meri and carpi smooth dorsally; propodi with pair of terminal spines preceded by row of five to seven spines along distal half to two-thirds, flexor margin without convex distal margin; dactyli without fringe of plumose setae, with sharp triangular spines on flexor margin, distal two slightly separated from third. <i>Remarks:</i> Two specimens (a male and a female) of <i>Uroptychus politus</i> were recorded by Henderson (1885) but only the female and a single left cheliped remain of the type series. <i>Distribution:</i> Presently known only from west of the Kermadec Islands at 1098 m (Fig. 5).
