Supplemental description
Penis 2.5 times as long as broad in lateral view, armed with about 15 short plumose setae on posterior margin and three short, naked setae near apex of posterolateral part; apex rounded armed with three long, mesially curved setae and a short seta ( Figure 4A View Figure 4 ).
Female with tuft of setae on sixth thoracopod and with developed oostegites on seventh and eighth thoracopods; oostegite on seventh thoracopod with baling lobe.
Fourth pleopodal endopod of male six-segmented; third, fourth, and fifth segments armed with modified seta at mesial distal angle, these setae extending beyond tip of terminal setae on ultimate segment, slightly thicker than others and furnished with fine setae on distal one-fourth ( Figure 4 View Figure 4 B–D). Fourth pleopodal exopod of male six-segmented, as long as endopod, without modified setae ( Figure 4B View Figure 4 ).
Fifth pleopodal endopod of male six-segmented, without modified setae ( Figure 4E View Figure 4 ). Fifth pleopodal exopod of male six-segmented, as long as endopod; fourth and fifth segments armed with modified seta at mesial distal corner, these modified setae with same setulation as those of endopod of fourth pleopod ( Figure 4E View Figure 4 ).
Distribution
This species is widely distributed in the meso- and bathypelagic zones deeper than 500 m of the Atlantic, Indian, and West Pacific Oceans: Ireland ( Holt and Tattersall 1905, 1906; Tattersall 1911), Iceland ( Hansen 1908), the Denmark Strait ( Stephensen 1912, 1933), Great Britain ( Tattersall and Tattersall 1951), South Africa ( Zimmer 1914; Illig 1930; Tattersall 1955), Sri Lanka ( Illig 1930), the Gulf of Aden ( Coifmann 1936b), northeastern USA ( Tattersall 1951), Somalia ( Birstein and Tchindonova 1962), Indonesia ( Pillai 1965; present study), the Arabian Sea ( Pillai 1965), and Japan ( Ii 1964; Murano 1977; present study).
This species was collected by trawl ( Holt and Tattersall 1905; Tattersall 1911; Stepehnsen 1933, present study), a net towed vertically or obliquely ( Hansen 1910; Illig 1930; Birstein and Tchindonova 1962; Ii 1964; Murano 1977; present study), and a bottom net ( Murano 1977).
Remarks
The presence of modified setae on the male pleopods and the components of the marsupium are reported for the first time.
