Anatoma   “East coast”: Jansen, 1999: 49, figs. 13–15.

Type material. HOLOTYPE AMS C.431072. 1.47 mm.

PARTAYPES: AMS C.29025, 8. AMS C.402671, 1. AMS C.402672, 1. AMS C.402673, 7. AMS C.402674, 1. AMS C.406337, 5.

Type locality. West of D’Entrecasteaux Channel , SE Tasmania, Australia, 43.045°S 147.347°E GoogleMaps   .

Etymology. The sculpture of fine, irregularly intersecting lines is reminiscent of the paintings of Mark Tobey (1890–1976: cf. Anonymous, 1997): tobey­: referring to the painters surname; ­oides: Latin: like, similar to.

Description. Shell globular, medium size to large (4.2 mm). Protoconch 3/4 whorls, flocculant sculpture, no apertural varix. Teleoconch I fewer than 0.5 whorls, no spiral cord in position of selenizone, fine centrifugal markings, strong axials present. Teleoconch II up to 2 1/4 whorls (1.6 mm shell). Sculpture with axials predominant, approximately 85 on body whorl on fully grown shell, approximately 15 spiral threads on shoulder at apertural margin. Approximately 25 spiral threads on base. Umbilicus continuously sloping from base, narrow, deep. Selenizone at periphery, keels distinct, growth marks poorly coordinated with axials. Aperture rounded, somewhat flared. Animal unknown.

Differential diagnosis. Anatoma tobeyoides   n. sp. is most similar to A. australis   . However, A. tobeyoides   n. sp. lacks the protoconch varix found in A. australis   , has a teleoconch I of less than half a whorl, whereas in A. australis   it has more than half a whorl, A. tobeyoides   n. sp. lacks a spiral cord on teleoconch I whereas A. australis   has a prominent one, and A. tobeyoides   n. sp. has much weaker spirals than axials and centrifugal spirals on teleoconch I and early teleoconch II, whereas A. australis   has spirals and axials of equal strength and lacks the centrifugal spirals.

Distribution. South Australia, Tasmania (43.2°S) through Queensland (21.7°S), 27– 1330 m shells only, 154 m live.
