Lanceophora n. g. Thandar, Zettler & Arumugam, 2010
Etymology: The name is derived from lancea L. – lance and phora Gk.- bearing, with reference to the lance-like deposits of the body wall.
Diagnosis: Small (up to 27 mm) cucumariid holothuroids with a slightly curved barrel-shaped body, tentacles 10, two ventral tentacles reduced or absent; tube feet restricted to ambulacra in 1–2 rows, interambulacra naked. Calcareous ring simple, no posterior prolongations to the radial plates; body wall deposits a superficial layer comprising a smooth to knobbed basal part bearing a long lance-like projection held in the same plane as the basal part, and an inner layer of large, smooth to knobbed multilocular plates.
Type species: Cucumaria souriei Cherbonnier, 1949a (here designated)
Other species included: Lanceophora lanceolata Thandar, Zettler & Amrumugam, 2010
Remarks: A new genus is here erected to accommodate only the type species and the new species described below. Lanceophora comes very close to Panningia but differs from it in the presence of a barrel-shaped rather than a U-shaped body form, reduced ventral tentacles, lack of any posterior prolongations to the radial plates of the calcareous ring, and that the lance-like prolongation of the superficial deposits is not held at an angle to the main body of the ossicle but in the same plane. C. souriei is chosen as the type species since the new species may prove to be conspecific with it. Although Cherbonnier (1963) did compare his Panningia crosnieri with C. souriei he did not refer the latter species to Panningia but let it stand as originally described.

Grandidierella ischienoplia Bochert & Zettler, 2010
Material examined: Holotype: one male (2.2 mm, ZMB 27841, 1 slide ZMB 5005) (AHAB9, 121; South Atlantic, shelf coast off Angola; water depth 44 m, dredge sampling; 8°45.320'S; 13°12.890'E; salinity at bottom 35.8 PSU, temperature at bottom 18.2°C, oxygen at bottom 1.58 ml/l; collected by S. Forster, 2 June 2004). Paratype: one male (ZMB 27842) data same as holotype (mounted on 6 slides, ZMB 5006-5011)
Etymology: The specific name “ischienoplia” is a combination of the Greek ischion = ischium (segment of limb) and enoplus = armed: alluding to the strong projection of third segment of the male gnathopod 2. The Latin form of enoplus is enoplius. The name is used as an adjective.
Habitat: On a bottom of silty sand, at 44 m depth.
Distribution: Only known from the type locality.
