Cancellocochlea
n. gen.
Diagnosis.
Shell very small, orange brown, biconcave or discoidal/planate with tightly coiled whorls, the last inflated. Protoconch sculpture reticulate (
coolongolook
) to spiral (
heatherae
); teleoconch with few sinuate radial ribs; microsculpture cancellate consisting of prominent microradial ribs and low microspiral cords, beaded at their intersection. Aperture narrowly to broadly ovately-lunate. Umbilicus wide U-shaped to wide cup-shaped. Penis tubular with an apical verge that has a lateral pore; longitudinal ridge shaped pilasters present. Epiphallus shorter than penis.
Range and habitat.
From the Port Stephens area northward to the Manning River drainage basin, NSW; found in rainforest on volcanics, living under logs and rocks.
Remarks.
Cancellocochlea coolongolook
n. sp.
and
Ca. heatherae
n. sp.
display significant differences in protoconch sculpture. The protoconch sculpture of
Ca. coolongolook
has similarities to both
Planorbacochlea parriwiensis
and
P. yessabahensis
(both reticulate) while the beaded spiral pattern of
Ca. heatherae
links it to the Hunter/Port Stephens
Planorbacochlea
group.
