Macrochiridothea kruimeli Nierstrasz, 1918 Macrochiridothea kruimeli Nierstrasz, 1918: 130 –132, figs 13, 54– 64. — Nordenstam, 1933: — Nierstrasz, 1941: 279. — Sheppard, 1957, 172– 173, fig. 13. — Menzies, 1962: 101, fig. 51 J. — Moreira, 1973: figs 7–8. — Carvacho, 1997: 51 (list). Material. Holotype : Punta Arenas, 53 °09'S, 70 ° 55 'W, Chile, ZMA (female, 15 mm). Diagnosis. Total body length of male 8 mm; female 15 mm. Dorsal surface rugose, posterior pereonites and pleonites with median ridge; pleotelson smooth. Lateral lobes on head acute. Coxa 6 reaching posteriorly to pleonite 3. Antenna 1 peduncle article 2 without anterodistal prolongation. Antenna 2 peduncle, article 4, 2.2 times as long as greatest width; article 5, 8 times as long as greatest width. Pereopods 2 and 3 dactyli subchelate, closing on truncate palm. Pereopod 5 ischium without a prominent hook on upper margin. Pleopod 2, appendix masculina straight, apex laterally denticulate. Distribution. Southern Chile and off southern Argentina; to 107 m depth. Remarks. Nierstrasz’s (1918) drawings are small and his photograph difficult to interpret. Sheppard (1957) added details of antennae and mouthparts from a male taken east of southern Argentina (49 ° 29´S, 66 ° 21´W, 104–107 m depth; Discovery stn WS 809). The species is characterised its large size and a rugose dorsum but is otherwise similar to M. setifer. : Published as part of Poore, Gary C.
