Anatoma funiculata new species: Figures 7–8 View FIGURE 7 View FIGURE 8 , 18 View FIGURE 18

Type material. HOLOTYPE ( AMS C.403660) . PARATYPES ( AMS C.205271 [ex AMS C.403660], 1. AMS C.402656, 1) .

Type locality. 21 m, SW side Euston Reef , GBR, QLD, Australia, 16.667°S, 146.217°E GoogleMaps .

Etymology. Funiculus, Latin: strand of material, referring to the thick spiral cord in the umbilicus.

Description: Shell globular, small to medium size (to 1.28 mm width: holotype). Protoconch 3/4 whorl, with flocculant sculpture, one or two faint spiral streaks, no varix. Teleoconch I 1/3 whorl, 8 axials, no spirals, interaxials smooth. Teleoconch II up to two whorls (holotype), axials 75 on body whorl of holotype; shoulder with 7 spirals, base with 15 spirals, both forming points at intersection with axials. Umbilicus open, deep, sloping continuously from base; funiculus in umbilicus fusing with apertural margin. Selenizone at periphery, keels distinct. Slit parallel, open anteriorly. Aperture rounded, somewhat flared, with shelf towards umbilicus fusing with umbilical funiculus. Animal unknown.

Differential diagnosis. Thieleella equatoria is similar in overall shape and sculpture, however, T. equatoria has a protoconch with reticulate sculpture, teleoconch I of more than 0.5 whorls, a wider umbilicus, and more numerous and stronger axials. Anatoma australis is more globular in overall shape, has a teleoconch I of more than 0.5 whorls and with spiral sculpture, and lacks the funicular strand in the umbilicus. Anatoma tobeyoides n. sp. is more globular in outline, has the irregular centrifugal markings on teleoconch I, less pronounced keels on the selenizone, and lacks the funicular strand in the umbilicus. Anatoma aupouria is wider in overall outline of the shell, has more numerous spirals on the shoulder, more axials on the base, the base axials showing the characteristic opisthocline loops/embayments. Anatoma turbinata is much more high­spired, has a teleoconch I of more than 0.5 whorls with spiral sculpture, and lacks the funicular strand in the umbilicus.

Distribution. Only known from the type locality (GBR, QLD, Australia).
