(Figs 7–8) Type material Holotype (ZSM Mol 20070895), leg. Katrin Linse, February 4 2002, ANT XIX/ 3 (ANDEEP I). Paratypes, one from type locality (ZSM Mol 20021185). Two paratypes (ZSM Mol 20021177) Antarctica, Drake Passage, St. PS 61 / 042–02 (59 ° 40.29 ’S 57 ° 35.43 ’W to 59 ° 40.42 ’S 57 ° 35.27 ’W), 3680–3683 m, Katrin Linse, January 27 2002, ANT XIX/ 3 (ANDEEP I). Besides the SEMmounted holotype, all other specimens are fixed and preserved in 96 % ethanol. Type locality: Antarctica, South Shetlands, St. PS 61 /043–08 (60 ° 27.12 ’S 56 °05.10’W to 60 ° 27.18 ’S 56 °04.80’W), 3959–3961 m (Fig. 8). Etymology: The species is named after our friend Jens Michael Bohn (ZSM), a holothurian specialist and participant of the relevant expeditions. We selected his surname because his nickname is “ Bohni ”. Description: Shell minute, up to 1.30 mm long, 1.28 mm wide (Fig. 7 A), globosely turbinate, fragile, translucent white in color, with inflated whorls slightly depressed at the shoulder, slightly expanded laterally, low spired, spire angle ranging from 80 ° (smallest paratype) to 85 ° (holotype). Protoconch (Fig. 7 D) of 1.25 whorls, 280 µm in diameter, 100 µm high, globose, sculptured with fine anastomosing threads, forming microscopic pits of irregular arrangment. Teleoconch (Figs 7 A, C) of up to 2.75 whorls with convex profile. Suture incised. Last adult whorl globose, slightly depressed at shoulder. Aperture oval, peritreme holostomate, although very weak at periphery of preceeding whorl; with thick inner, thin outer lip. Shell base roundly inflated. Umbilicus (Fig. 7 B) tightly open, circular, deep. Axial sculpture of narrow ribs, ranging from 29 (largest paratype) to 31 on last whorl in holotype, 25 on penultimate whorl. Ribs regularly spaced, rounded, low, interspaces about three times rib width. Spiral sculpture of numerous flat threads, seven on first teleoconch whorl, about 12 on last adult whorl, narrower than axial ribs, crowded in upper and lower half of whorl, centrally ...
