Description
Neolepidotrochus parvidiscus angolensis Bohn, 2005
(Figs 13 B–C, 14)
Neolepidotrochus parvidiscus angolensis Bohn, 2005: 234 –237, figs 1(C–G), 3, 4
Material. M 48/1340: Holotype (ZSM 20020017).
Remarks. This subspecies has been recently described in more detail (Bohn 2005) and is characterised by: body wall and tentacle bases with two types of wheel deposits, neolepidotrochid type wheels (Fig. 13 B) and myriotrochid type wheels (Fig. 13 C). Neolepidotrochid type wheels with variable number (up to 16) of outwardpointing secondary teeth (Fig. 12 B: arrowheads), not present in all wheels, but in the majority; edge of rim between two outwardpointing primary teeth roughly straight; neolepidotrochid type wheels from anterior body smaller (mean diameter: 111, range: 95–129), than wheels from posterior body (mean diameter: 140, range: 127–158) and with higher ratio of hub diameter to wheel diameter (mean: 40 %, range: 30–47 %) compared to wheels from posterior body (mean: 29 %, range: 22–36 %). Myriotrochid type wheels have a diameter of 130 (75–166), ratio of hub diameter to wheel diameter 21 % (18–26 %), spokes 10 (8–14).
Distribution. (Fig. 14) Angola Basin in the southeastern Atlantic Ocean, 5395 m.
