 issued from : W. Vervoort in Verh. K. ned. Akad. Wet., Afd. Natuurk., 1951, (Sect. 2) 47 (2). [p.122, Fig.65]. Female (from ± 66°.5S, 11°W): habitus (lateral). Nota: Head and 1st thoracic somite separated, 4th and 5th fused. Postero-lateral margin of the last thoracic somite is not smoothly rounded, but produced into a minor knob, distinctly visible in dorsal and lateral views. A1 reaching the middle of the abdomen (or even slightly longer); the 8th-9th segments completely fused and these segments partly fused with the 10th.

 issued from : W. Vervoort in Verh. K. ned. Akad. Wet., Afd. Natuurk., 1951, (Sect. 2) 47 (2). [p.123, Fig.66]. Female: a, urosome (dorsal); b, right P4 (anterior); c, P5 (anterior). Nota: Genital segment formed by fusion of the first 3 urosomal somites, slightly longer than the combined length of the intermediate abdominal segment and anal segment, which two segments have the same length. Caudal rami slightly longer than the anal segment and about twice as long as wide. Exopod of P4 with very short endspine (exactly 1/3 the length of the 3rd exopodal segment); in this respect the females, here, differ from Gisebrecht's account.

Sampling depth (Antarct., sub-Antarct.) : 200-1000 m. Sargasso Sea: 500-2000 m (Deevey & Brooks, 1977, Station "S"); 495-1646 m at Station S1 (SE Hokkaido) in the Oyashio region.
According to Vervoort (1951, p.121) the male, unknown to Giesbrecht, is mentioned by Farran and Lysholm & al., but it is still undescribed. The female, which is not so easily distinguished from M. lucens, differs by the shape of the last thoracic segment; the proportional length of the urosomal segments and the caudal rami, the structure of P5 and the length of the enspine of the exopod of P4.
For Bradford-Grieve (1999 b, p.113) the Southwest Pacific specimens appear to differ slightly from the Vervoort's description because the "minor" knob on the posterior metasomal corners inconspicuous, and no outer distal spine was observed on the 3rd segment of the female P5.
For Bradford '1971 b, p.24) the species seems to inhabit both the Deep Warm Water and Antarctic Bottom Water (Vervoort, 1965), hence its wide distiburion. | | | Last update : 07/12/2020 | |
