UROPTYCHUS POLITUS ( HENDERSON, 1885) View in CoL

Diptychus politus Henderson, 1885: 420 [type locality: Kermadec Islands   GoogleMaps , 28° 33.00′S, 177° 50.00′W, 1098 m, 15.vii.1874, Challenger stn 171].

Uroptychus politus View in CoL . – Henderson, 1888: 178, pl. 6: fig 2 a, b. – Thomson, 1899: 196 (list). – Baba, 1974: 387, fig. 5. – Baba, 2005: 219 (key), 230 (list).

Type material: 1 ovig. ♀, syntype, (7.2 mm), Kermadec Islands , 28° 33.00′S, 177° 50.00′W, 1098 m, 15.vii.1874, Challenger stn 171 ( BMNH 1888 : 33) GoogleMaps .

Diagnosis: 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.

Remarks: Two specimens (a male and a female) of Uroptychus politus were recorded by Henderson (1885) but only the female and a single left cheliped remain of the type series.

Distribution: Presently known only from west of the Kermadec Islands at 1098 m ( Fig. 5 View Figure 5 ).
